PROGRESS REPORT OF STREAM MEASUR.EMENTS 

FOR THE CALENDAR YEAR 1905. 

PART XI. 

By M. C. HINDERLIDER and G. L. SwENDSEN. 

INTRODUCTION. 

ORGANIZATION AND SCOPE OF WORK. 

The hydrographic work of the United States Geological Survey includes the collecton bf 

facts concerning and the study of conditions affecting the behavior of water from the time it 

reaches the earth as rain or snow until it joins the oceans or great navigable rivers. These 

investigations became a distinct feature of the work of the Survey in the fall of 1888, when 

an instruction camp was established at Embudo, N. Mex. The first speeific appropriation 

for gaging streams was made by the ad of August 18,1894, which contained an item of $12,500 

"for gaging the streams and determining the water supply of the United States, including 

the investigation of underground currents and artesian wells in the arid and semiarid sections." (28 Stat. L., p. 398.) 

Since that time the appropriations have been gradually increased, as shown by the following table:

1900 ........................................ 50,000 1906 ···········-····················-····· 200,000 

As a result of the increased appropriations the work has been greatly extended, and at the 

same time it has been more thoroughly systemized by the adoption of standard methods and 

by grouping the States into districts, in each of which a district hydrographer and a corps of 

assistants carry on a comprehensive study of the hydrbgraphic resources. 

The chief features of the hydrographic work are the coJlection of data relating to the flow 

of surface waters and the study of the conditio~s affecting this flow. Information is also collected concerning river profiles, duration and magnitude of floods, water power, etc., which 

may be of use in hydrographic studies. This work includes the study of the hydrography of 

:wery important river basin in the United States and is of direct value in the commercial and 

agricultural development of the country. 

In order to collect the material from which estimates of daily flow are made gaging stations are established. The selection of a site for a gaging station and the length of time it is 

maintained depend largely on the physical features and the needs of each locality. If the 

water is to be used for power special effort is made to obtain information concerning the 

1

minimum :Bow; if water is to be stored the maximum flow receives special attention. In all 

sections of the country permanent gaging stations are maintained for general statistical purposes, to show the conditions existing through long periods. They are also used as primary stations and their records in ~onnection with short series of measurements serve as 

bases for estimating the :Bow at other points in the drainage basin. 

During the calendar year 1905 the division of hydrography has continued measuring the· 

:Bow of streams on the same general lines as in previous years. Many new and improved 

methods have been introduced, by which the accuracy and value of the results have been 

increased. Approximately 800 regular gaging stations were maintained during the year 

and an exceptionally large number of miscellaneous measurements and special investigations 

were made. The" Report of Progress of Stream Measurements," which contains the results 

of this work, is published in a series of fourteen Water-Supply and Irrigation Papers, Nos. 

165 to 178, as follows: 

No.165. Atlantic coast of New England drainage. 

No. 166. Hudson, Passaic, Raritan, and Delaware River drainages. 

No. 167. Susquehanna, Gunpowder, Patapsco, Potomac, James, Roanoke, and Yadkin river drainages. 

No. 168. Santee, Savannah, Og_eechee, and Altamaha rivers and eastern Gulf of Mexico drainages. 

No. 169. Ohio and lower eastern Mississippi river drainages. 

No.170. Great Lakes and St. Lawrence River drainages. 

No. 171. Hudson Bay and upper eastern and western Mississippi River drainages. 

No. 172. Missouri River drainage. 

No. 173. Merarnec, Arkansas, Red, and lower western Mississippi river drainages. 

No.174. Western Gulf of Mexico and Rio Grande drainages. 

No.175. Colorado River drainage above Yuma. 

No. 176. The Great Basin drainage. 

No. 177. The Great Basin and Pacific Ocean drainages in California and Colorado River drainage below 

Gila River. 

No.178. Columbia River and Puget Sound drainages. 

These papers embody the data collected at the regular gaging stations, the results of the 

computations based on the observations, and such other information as may have a direct 

bearing on the study of the subject, and include, as far as practicable, descriptions of the 

basins and the streams draining them. 

For the purpose of introducing uniformity into the reports for the various years the drainages of the United States have been divided into eleven grand divisions, which have been 

again divided into secondary divisions, as shown in the following list. The Progress Report 

has been made to conform to this arrangement, each part containing the data for one or 

more of the secondary divisions. The secondary divisions have in most cases been redivided, 

and the facts have been arranged, as far as practicable, geographically.

DEFINITIONS.

The volume of water flowing in a stream, the "run-off" or "discharge," is expressed in 

various terms, each of which has become associated with a certain class of work. These 

terms may be divided into two groups-(1) tpose which represent a rate of flow, as second-feet, 

gallons per minute, miner's inch, and run-off in second-feet per "square mile; and (2) those 

which represent the actual quantity of water, as run-off in depth in inches and acre-feet. 

They may be defined as follows: 

"Second-foot" is an abbreviation for cubic foot per second, and is the rate of discharge 

of water flowing in a stream 1 foot wide, 1 foot deep, at a rate of 1 foot per second. It is 

generally used as a fundamental unit from which others are computed. 

"Gallons per minute" is generally used in connection with pumping and city water 

supply. 

Th~ "miner's inch" is the rate of discharge of water that passes through an orifice 1 in<.,h 

square under a head which varies locally. It has been commonly used by miners and irrigators throughout the West, and is defined by statute in each State in which it is used. In 

most States the California miner's inch is used, which is the fiftieth part of a second-foot. 

"Second-feet per square mile" is applied to the average number of cubie feet of water 

flowing per second from eac.h square mile of area drained, on the assumption that the run-off 

is distributed unifoTI:nly both as regards time and area. 
4 STREAM MEASUREME~TS IN 1905, PART XI. 

"Run-off in inches" is the depth to which the drainage area would be covered if all the 

water flowing from it in a given period were conserved and m1iformly distributed on the surface. It is used for comparing run-off with rain fall, which is usually expressed in depth in 

inches. 

"Acre-foot" is equivalent to 43,560 cubic feet, and is the quantity required to cover 

an acre to the depth of 1 foot. It is commonly used in connection with storage for irrigation work. There is a convenient relation between the second-foot and the acre-foot. One 

second-foot flowing for twenty-four hours will de.liver 86,400 cubic feet, or approximately 

2 acre-feet. 

EXPLANATION OF TABLES. 

For each regular gaging station are given, as far as available, the following data: 

1. Description of station. 

2. List of discharge measurements. 

3. Gage-height table. 

4. Rating table. 

5. Table of estimated monthly and yearly discharges and run-off, hased on all the facts 

obtained to date. 

The descriptions of stations give such general information about the locality and equipment as would enable the reader to find and use the station. They also give, as far as possible, a complete history of all the ehanges since the establishment of the station that would 

be factors in using the data colJected. 

The discharge-measurement table gives the results of the discharge measurements made 

during the year, including the date, the name of the hydrographer, the area of cross section, the mean velocity, the gage height, and the discharge in second-feet. 

The table of daily gage heights gives the daily fluctuations of the surface of the river as 

found from the mean of the gage readings taken each day. The gage height given in thetable repr~sents the elevation of the surface of the water above the zero of the gage. At most 

stations the gage is read in the moming and in the evening. 

The rating table gives discharges in second-feet corresponding to each stage of the river as 

given by the gage heights. 

In the table of estimated monthly discharge, the column headed ''Maximum" gives the 

mean flow for the day when the mean gage height was highest, and it is the flow as given ·in 

the rating table for that mean gage height As the gage l:tetght is the mean for the day, 

there might have been short periods when the water was higher and the corresponding discharge larger than given in this column. Likewise, in the column of'' Minimum," the quantity given is the mean flow for the day when the mean gage height was lowest The column 

headed "Mean'' is the average flqw tor each second during the month. On this are based 

the computations for the three remaining columns, which are defined above. 

In the computations for the tables of this report the followmg general and special rules 

have been used: · 

Fundamental rules for computation. 

1. The highest degree of precision consistent with the rational use of time and money is imperative. 

2. All items of computation should be expressed by at least two and not more than four significant 

figures. · 

3. Any measurement in a vertical velocity, mean velocity, or discharge curve whose per cent of error 

is five times the average percent of error of all the other measurements should be rejected. 

4. In reducing the number of significant figures, or the number of decimal places, by dropping the last 

figure, the following rules apply: 

(a) When the figure in-the place to be rejected is less than 5, drop it without ch.::.nging the preceding 

figure. Example: 1,827.4 becomes 1,827. 

(b) When the figure in the place to be rejected is greater than 5, drop it and in~rease the preceding figure by 1. Exam pie: 1,827.6 becomes 1.828. 

(c) When the figure in the place to be rejected is 5, and it is preceded by an even figure, drop the 5. 

Example: 1,828.5 becomes 1,828. 

(d) When the figure in the place to be rejected is 5, and it is preceded by an odd figure, drop the 5 

and increase the preceding figure by 1. Example; 1,827.5 becomes 1,828. 
CONVENIENT EQUIV A.LENTS. 5 

Special roles for computation. 

1. Rating tables are to be constructed as closely as the data on which they are based will warrant. 

No decimals are to be used when the discharge is over 50 second-feet. 

2. Daily discharges shall be applied dire.ctly to the gage heights as they are tabulated. 

3. Monthly means are to be carried out to one decimal place when the quantities are below 100 second-feet. Between 100 and 10,000 second-feet the last figure in the m~nthly mean shall be a significant 

figure. This also applies to the yearly mean. 

4. Second-feet per square mile and depth in inches for the individual months shall be carried out 

to at least three significant figures, except in the case of decimals where the first significant figure is 

preceded by one or more naughts (Ol, when the quantity shall be carried out to two significant 

figures. Example: 1.25; 0.125; 0.012; 0.0012. The yearly means for these quantities are always to be 

expressed in three significant figures and at least two decimal places.

FIELD METHODS OF MEASURING STREAM FLOW. 

The methods used in collecting these data and in preparing them for publication are 

given in detail in Water-Supply Papers No. 94 (Hydrographic Manual U. S. Geological 

Survey) and No. 95 (Accuracy of Stream Measurements). In order that those who use 

this report may readily become ac-quainted with the general methods employed, the following brief description is given: 

Streams may be devided with respect to their physical conditions into three classes-(1) 

those with permanent beds; (2) those with beds which change only during extreme low or 

high water; (3) those with constantly shifting beds. In estimating the daily :Bow special 

methods are uecessary for each class. The data on which these estimates are based and 

the methods of collecting them are, however, in general the same. 

There are three distinct methods of determining the :Bow of open-channel streams-(1) 

by measurements of slope and cross section and the use of Chezy's and Kutter's formulas; 

(2) by means ·of a weir; (3) by measurements of the velocity of the current and of the 

area of the cross section. The method chosen for any case depends on tlie local physical 

conditions, the degree of accuracy desired, the funds available, and the length of time that 

the record is to be continued. 

Slope method.-Much information has been collected relative to the coefficients to be 

used in the Chezy formula v=cvrs. This has been utilized by Kutter, both .in developing 

his formula for c and in determining the values of the coefficient n which appears therein. 

The results obtained by the slope method are in general only roughly approximate, owing 

to the difficulty in obtaining accurate data and the uncertainty of the value for n to be 

used in Kutter's formula. The most common use of this method is in estimating the flood 

discharge of a stream when the only data available are the cross section, the slope as shown 

by marks along the bank, and a knowledge of the general conditio:p.s. 

Weir method.-When funds are available and the conditions are such that sharp-crested 

weirs can be erected, these offer the best facilities for determining :Bow. H dams are suitably situated and constructed, they may be utilized for obtaining reliable estimates of :Bow. 

The conditions necessary to insure good results may be divided into two classes-(1) those 

relating to the physical characteristics of the dam itself, and (2) those relating to the diversion and use of the water around and through the dam. 
FIELD :METHODS OF MEASURING '-FLOW. 7 

The physical requirements are as follows: (a) Sufficient height of dam, so that backwater 

will not interfere with free fall over it; (b) absence of leaks of appreciable magnitude; (c) 

topography or abutments which confine the flow over the dam at high stages; (d) level 

crests, which are kept free from obstructions caused by floating logs or ice; (e) crests of a 

type for which the coefficients to be used in Q=c b hi, or some similar standiird weir formula, 

'are known (see Water-Supply Paper No. 150); (f) either no flash boa·ffis or exceptional 

care in reducing leakage through them and in recording their condition. 

Preferably there should be no diversion of water through or around the dam. Generally, 

however, a dam is built for purposes of power or navigation, and part or all of the water 

flowing past it is diverted for such uses. This water is measured and added to that passing 

over the dam. To insure accuracy in such estimates, the amount of water diverted should 

be reasonably constant. Furthermore, it should be so diverted that it can be measured, 

either by a weir, a current meter, or.a simple system of water wheels which are of standard 

make or which have been rated as ll).eters under working conditions and so installed that 

the gate openings, the heads under which they work, and their angular velocities may be 

accurately observed. 

The combination of physical conditions and uses of the water should be such that the 

estimates of flow will not involve for a critical stage of considerable duration the use of a 

head on a broad-crested dam of less than 6 inches. Moreover, when all other eonditions 

are good, the cooperation of the owners or operators of the plant is still essential if reliable 

results am to bJ obtained. 

FIG. 1.--Cable station, showing section of river, car, gage, etc. 

A gaging station at a weir or dam has the general advantage of continuity of record 

through the period of iee and floods and the disadvantages of uncertainty of coefficient to 

be used in the weir formula and of complications in the diversion and use of the water. 

Velocity method.-The determination of the quantity of wate.r flowing past a certain section of a stream at a given time is termed a discharge i:neasurement. This quantity is the 

product of two factors-the mean velocity and the area of the cross seetion. The mean 

velocity is a function of surface slope, wetted perimeter, roughness of bed, and the channel 

conditions at, above, and below the gaging section. The area depends on the contour of 

the bed and the fluctuations of the surface. The two principal ways of measuring the 

velocity of a stream are by floats and current meters. 

Great care is taken in the selection and equipment of gaging stations for determining discharge by velocity measurements in order that the data may have the required degree of 

accura.cy. Their essential requirements are practieally the same whether the velocity is 

determined by meters or floats. They are located as far as possible where the channel is 

straight both above and below the gaging section; where there are no cross currents, backwater, or boils; where the bed of the stream is reasonably free from large projec.tions of a 

permanent charac.ter, and where the banks are high and subject to overflow only at flood 

stages. The station must be so far removed from the effects of tributary streams and dams 

or other artificial obstructions that the gage height shall be an index ot\he discharge. 
8 STREAM MEASUREMENTS IN 1905, PART XI. 

Certain permanent or semipermanent structures usually referred to as ''equipment" are 

generally appurtenant to a gaging station. These are a gage for determining the fluctuations of the water surface, bench marks to which the datum of the gage is referred, permanent marks on a bridge or a tagged line indicating the points of measurement, and, where 

the current is swift, some appliance (generally a secondary cable) to hold the meter in position in the water. As a rule the stations are located at bridges if the channel conditions 

are satisfactory, as from them the observations can more readily be made and the cost of 

the equipment is small. 

The floats in common use are the surface, subsurface, and t1,1be or rod floats. A corked 

bottle with a flag in the top and weighted at the bottom makes one of the most satisfactory 

surface floats, as it is affected but little by wind. In case of flood measurements, good 

results can be obtained by observing the velocity of floating cakes of ice or debris. In case 

of all surface-float measurements, coefficients must be used to reduce the observed velocity 

to the mean velocity. The subsurface and tube or rod floats are intended to give directly 

the mean velocity in the vertical. Tubes give excellent. results when the channel conditions 

are good, as in canals. 

In measuring velocity by a float, observation is made of the time taken by the float to 

pass over the" run," a selected stretch of river from 50 to 200 feet. long. In each discharge 

measurement a large number of veloeity determinations are made at different points aeross 

the stream, and from these observations the mean veloeit.y for the whole section is determined. 

This may be done by plotting the mean positions of the floats as indicated by the distanees 

from the bank as or.dinates and the corresponding times as abscissas. A curve through these 

points shows the mean time of run at any point across the stream, and the mean time for the 

whole stream is obtained by dividing the area bounded by this curve and its axis by the 

width. The length of the nm divided by the mean time gives the mean velocity. 

The area used in float measurements is the mean of the areas at the two ends of the run 

and at several intermediate seet.ions. 

The essential parts of the current meters in use are a wheel of some type, so construGted 

that the impact of flowing water causes it to revolve, and a deviee for recording or indicating the number of revolutions. The relation between the veloeity of the moving water and 

the revolutions of the wheel is determined for each meter. This rating is done by drawing 

the meter through still water for a given distance at different speeds and noting the number 

of revolutions for each run. From these data a rating table is prepared whieh gives the 

velocity per second for any number of revolutions. 

Many kinds of current meters have been constructed. They may, howev.er, be classed in 

two general types-those in which the wheel is made up of a series of eups, as the Price, and 

those having a screw-propeller wheel, as the Haskell. Each meter has been developed for 

use under some special condition. In the case of the small Price meter, which has been 

largely developed and extensively used by the United States Geological Survey, an attempt 

has been made to get an instrument which could be used under practically all conditions . 

. Current-meter measurements may be made from a bridge, cable, boat, or by wading, and 

gaging stations may be classified in accordance with such use. Fig. 1 shows a typical cahle 

station. 

In making the measurement an arbitrary nurnber of points are laid off on u line perpendicular to the thread of the stream. The points at which the velocity and depth are observed are 

known as measuring points, and are usually fixed at regular intervals, varying from 2 to 20 

feet, depending on the size and conditions of the stream. Perpendiculars dropped from the 

measuring points divide the gaging s~ction into strips. For each strip or pair of ~trips the 

mean velocity, area, and discharge are determined independently, so that conditions 

existing in one part of the stream may not be extended to parts where th~ do not apply. 

Three classes of methods of measuring velocity with current meters are in general usemultiple-point, single-point, and integration. 

The three principal multiple-point methods in general use are the vertical velocity curve, 

0.2 and 0.8 depth, and top, bottom, and mid-depth. 
FIELD METHODS OF MEASURING FLOW. 9 

In the vertical velocity-curve method n series of velocity determinations are made in each 

vertical at regular intervals, usunlly- from 0.5 to 1 foot apart. By plotting these velocities 

as abscissas and their depths as ordinates, n.nd drawing a smooth curve among the resulting 

points, the vertical velocity curve is developed. This curve shows graphically the magnitude 

and changes in velocity from the surface to the bottom of the stream. The mean velocity in 

the vertical is then obtained l,>y dividing the area bounded by this velocity curve and its axis 

by the depth. On account of the length of time required to make a complete measurement 

by this method, its use is limited to the determination of coefficients for purposes of comparison and to measurements under ice. 

In the second multiple-point method the meter is held successively at O.Z and 0.8 of the 

depth, and the mean of the velocities at these two points is taken as the mean velocity for 

that vertical. Assuming that the vertical velocity-curve-is a common pnrabola with horizontal axis, the mean of the velocities at 0.22 and 0.79 of the depth will give (closely) the 

mean velocity in the vertical. Actual observations under a wide range of conditions show 

that this second multiple-point method gives the mean velocity very closely for open-water 

conditions where the depth is over 5 feet and the bed comparatively smooth, and moreover 

the indications are that it will hold nearly as well for ice-covered rivers. 

In the third multiple~point method the meter is held at mid-depth, at 0.5 foot below the 

surface, and at 0.5 foot above the bottom, and the mean velocity is determined by dividing 

by.6 the sum of the top velocity, four times the mid-depth velocity, and the bottom velocity. 

This method may be modifieq by observing at 0.2, 0.6, and 0.8 depth. 

The single-point method consists in holding the meter either at the depth of the thread of 

mean velocity or at an arbitrary depth for which the coefficient for reducing to mean velocity 

has been determined. 

Extensive experiments by vertical velocity-curves show that the thread of mean velocity 

generally occurs at from 0.5 to 0.7 of the total depth. In general practice the thread of mean 

velocity is considered to be at 0.6 depth, at which point the meter is held in the majority of 

measurements. A large number of vertical velocity-curve measurements taken on many 

streams under and varying conditions show that the average coefficient for reducing the 

velocity obtained at 0.6 depth to mean velocity L'l practically unity. 

In the other principal single-point method the meter is held near the surface, usually 1 foot 

below, or low enough to be out of the effect of wind or other disturbing influences. This is 

known ns the subsurface method. The coefficient for reducing the velocity taken at the 

subsurface to the mean has been found to be from 0.8.5 to 0.95 depending on the stage, 

velocity, and channel conditions. The higher the stage the larger the coefficient. · This 

method i~ especially adnpted for flood measurements or when the velocity is so great that 

the meter can not be kept at 0.6 depth. 

The vertical-integration method consists in moving the meter at a slow, uniform speed 

from the surface to the bottom and back again to the surface, and noting the number of 

revolutions and the time taken in the operation. This method has the advantage that the 

velocity at each point in the vertical is measured twice. It is well adapted for measurements 

under ice and as a check on the point methods. 

The area, which is the other factor in the velocity method of determining the discharge of a 

stream, de~nds on the stage of the river, whi'ch is observed on the gage, and on the general 

contour of the bed of the stream, which is determined by soundings. The soundings at·e 

usually taken at each measuring point at the time of the discharge measurement, either by 

using the meter and cable, or by a special sounding line or rod. For streams with •permanent beds standard cross sections are usually taken during low water. These sections 

'serve to check the soundings which are taken at the time of the measurements, and from 

them any change which may have taken place in the bed of the stream can be detected. 

They are also of value in obtaining the area for use in computations of high-water measurements, as accurate soundings are hard to obtain at high stages. 

In computing the discharge measurements from the observed velocities .and ·depths at 

various points of measurement, the measuring section is divided into elementary strips, as 
10 STREAM MEASUREMENTS IN 1905, PART XI. 

shown b fig. 1, and the mean velocity, area, and discharge are determined separately for 

either a single or a double strip. The total discharge and the area are the sums of those 

for the various strips, and the mean veloeity is obtained by dividing the total discharge by 

the total area. 

The determination of the flow of an ice-eovered stream is difficult, owing to diversity and 

instability of conditions during the winter period, and also to lack of definite information 

in regard to the laws of flow of water under iee. The method now employed is to make 

frequent discharge measurements during the frozen periods by the vertical velocity-curve 

method and to keep an accurate record of the conditions, such as the gage height to the 

surface of the water as it rises in a hole cut in the ice, the thickness and character of the ice, 

etc. From these data an approximate estimate of the daily flow can be made by constructing a rating curve (really a series of curves) similar to that used for open channels, but considering in addition to gage heights and discharge varying thickness of ice. Such data as 

are available in regard to this subject are published in Water-Supply Paper No. 146, pp. 

141-148. 

OFFICE METHODS OF COMPUTING RUN -OFF. 

There are two principal methods of estimating run-off, depending. on whether or not the 

bed of the stream is permanent. 

For stations on streams with permanent beds the first step in computing the run-off is 

the eonstruction of the rating table, which shows the dischar~e corresponding to any stage

FIG. 2.-Rating, area, and mean-velocity curves for South Fork of Skykomish River near Index, Wash. 

of the stream. This rating tah1e is applied to the record of stage to determine the amount 

of water flowing. The construetion of the rating table depends on the method used in 

measuring flow. 

For a station at a weir or dam the basis for the rating table is some standard weir formula. 

The coefficients to be used in its application depend on the type of dam and other conditions near its crest. After inserting in the weir formula the measured length of crest and 

assumed coefficient the discharge is computed for various heads and the rating table eonstructed. 

The data necessary for the construction of a rating table for a velocity-area station are 

the results of the discharge measurements, which include the record of stage of the river at 

the time of measurement, the area of ·the cross section, the mean velocity of the current, 

and tho qu"antity of water flowing. A thorough knowledge of the conditions at and in the 

vicinity ef the station is also necessary. 
COOPERATION AND ACKNOWLEDGMENTS. 11 

The construction of the rating table depends on the following laws of flow for open permanent channels: (1) The discharge will remain eonstant so long as the conditions at or 

near the gaging station remains constant. (2) The discharge will be the same whenever 

the streil.m is at a given stage if the change of slope due to the rise and fall of the stream be 

neglected. (3) The discharge is a function of and increases gradually witli the stage. 

The platting of results of the various discharge measurements, using gage heights as 

ordinates and discharge, mean velocity, and area as abscissas, will define curves which 

show the discharge, mean velocity, and area corresponding to any gage height. For the 

development of these curves there should be, therefore, a sufficient number of discharge 

measurements to cover the range of the stage of the stream. Fig. 2 shows a typical rating 

curve with its corresponding mean velocity and area curves. 

As the discharge is the product of two factors, the area and the mean velocity, any change 

in either factor will produce a corresponding change in the di~harge. Their curves are 

therefore constructed in order to study each independently of the other. 

The area curve can be definitely determined from accurate soundings extending to the 

limits of high water. It is always concave toward the horizontal axis or on a straight line, 

unless the banks of the stream are overhanging. 

The form of the mean-velocity curve depends chiefly on the surface slope, the roughness 

of the bed, and the cross section of the stream. Of these, the slope is the principal factor. 

In accordance with the relative change of these factors the curve may be either a straight 

line, convex, or concave toward either axis, or a combination of the three. From a careful 

study of the conditions at any gaging station the form which the vertical velocity-curve 

will take ean be predieted, and it may be extended with reasonable certainty to stages 

beyond the limits of actual measurements. Its principal use is in connection with the 

area curve in locating errors in discharge measurements and in eonstructing the rating 

table. 

The discharge curve is defined primarily by the measurements of discharge which are 

studied and weighted in accordance with the loeal conditions existing at the time of eaeh 

measurement. The eurve may however, best be located between and beyond the measurements by means of eurves of area and mean veloeity. The discharge curve under normal conditions is concave toward the horizontal axis and is generally parabolic in form. 

In the preparation of the rating table the diseharge for each tenth or half tenth on the 

gage is taken from the curve. The differences between successive diseharges are then 

taken and adjusted aecording to the l~w that they shall either be eonstant or increasing. 

The determination of daily discharge of streams with ehangeable beds is a difficult problem. In ease. there is a weir or dam available, a condition whieh seldom exists on streams 

of this elass, estimates can be obtained by its use. In ease of velocity-area stations frequent 

diseharge measurements must be made if the estimates are to be other than rough approximations. For stations with beds which shift slowly or are materi~lly changed only during 

floods rating tables ean be prepared for periods between sueh changes and satisfactory 

results obtained with a limited number of measurementS', provided that some of them are 

taken soon after the change occurs. For streams with continually shifting beds, such as 

the Colorado and Rio Grande, discharge measurements should be made every two or three 

days and the discharges for intervening days obtained either by interpolation modified by 

gage heights or by Professor Stout's method, which has been deseribed in full in the Nineteenth Annual Report of the United States Geological Survey, Part IV, page 323, and in 

the Engineering News of April 21, 1904. This method or a graphical application of it is 

also much used in estimating flow at stations where the bed shifts but slowly.

GENERAL DESCRIPTION OF COLORADO RIVER DRAINAGE BASIN. 

Colorado River is formed in the southeastern par~ of Utah by the junction of Grand and 

Green rivers. Green River is larger than the Grand and is the upward continuation of the 

Colorado. Including the Green the entire length of the C.olorado is about 2,000 miles. The 

region drained is about 800 miles long, varies in width from 300 to 500 miles, and contains 

about 300,000 square miles. It comprises the southwestern part of Wyoming, the western 

part of Colorado, the eastern half of Utah, practically all of Arizona, and small portions of 

California, Nevada, New Mexico, and old Mexico. Most of this area is arid, the mean 

annual rainfall being about 8~ inches. The streams receive their supply from the melting 

snows on the high mountains of Wyoming, Utah, and Colorado. 

There are two distinc.t portions of the basin of the Colorado. The lower third is but 

little above the level of the sea, though here and there ranges of mountains rise to elevations of 2,000 to 6,000 feet. This part of the valley is bounded on the north by a line 

of cliffs which present a bold, often v.ertical, step hundreds or thousands of feet, to the 

table-land above. The upper two-thirds of the basin stands from 4,000 to 8,000 feet 

above sea ltlvel, and is bordered on the east, west, and north by ranges of snow-clad mountains which attain altitudes varying from 8,000 to 14,000 feet above sea level. Through this 

plateau the Colorado and its tributaries have cut narrow gorges or canyons in which they

flow at almost inaccessible depths. At points where lateral streams enter, the canyons are 

broken by narrow, transverse valleys, diversified by bordering willows, clumps of box elder, 

and small groves of cottonwood. The whole upper basin of the Colorado is traversed by a 

labyrinth of these canyons, most of which are dry during the greater portion of the year, and 

carry water only during the melting of the snow and the brief period of the autumnal and 

spring rains. 

Low mesas, dry and treeless, stretch back from the brink of the canyons, and beyond are 

long lines of brilliantly colored cliffs, scores or hundreds of miles in length and hundreds or 

thousands of feet in altitude, presenting steep or even vertical faces of rock. These cliffs 

form a series of terraces, and each marks the boundary "of some geological series of strata 

the edges of which are exposed, like courses of m~nry, in the scarp walls of the palisades.'' a 

The lateral extension of such a line of cliffs is very irregular, sharp salients being projected 

on the plains below an$1 dee{t recesses cut into the terraces above. 

The region is further diversified by short ranges of eruptive mountains. A vast system 

of fissures extends across the country, and huge cinder cones, red, brown, and black, stand 

along the fissures and form conspicuous landmarks, set, as they are, in contrast to the 

bright varigated rocks of sedimentary origin. b 

As a matter of convenience the drainage area has been divided into three basins: (1) 

Green River basin, (2) Grand River basin, and (3) Colorado River below the junction of 

Grand and Green rivers, and each of these basins is subdivided to allow the separate description of branches of the main river. 

GREEN RIVER DRAINAGE BASIN. 

AREA AND EXTENT. 

Green River and its tributaries drain an area rudely triangular in outline, bounded on the 

north and east by the Wind River Mountains and the ranges forming the Continental Divide, 

un the south and east by the White River ~lateau and the Roan or Book Clifs, and on the 

north and west by the Gros Ventre and Wyoming mountains and the great Wasatch Range. 

The greatest length of the basin, north and south, is ~bout 370 miles. In an east-west direction it measures at its widest point about 240 miles. The total drainage area is approximately 41,000 square miles. 

The area includes a large part of western Wyoming, northwestern Colorado, and eastern 

Utah. The Uinta and Uncompahgre Indian reservatwns are located in this basin in northeastern Utah. 

In the following account of the work of the United States Geological Survey in this region 

during 1905 the basin has been subdivided, as a matter of convenience, the main river being 

described first and the tributary streams, beginning at the headwaters, afterwards. 

GREEN RIVER. 

DESCRIPTION OF BASIN. 

Green River heads on the west slope of the Wind River Mountains in western Wyoming, 

its ultimate source being a number of small lakes fed by the glaciers and Immense snow 

deposits always to be found on Fremont and neighbormg peaks. For perhaps 25 miles the 

river flows northwestward through the mountains. It then turns abruptly and runs in a 

general·southerly direction across western Wyoming mto Utah. A few miles below the 

Wyoming-Utah boundary ~;tnother sharp turn carries the river eastward along the Uinta 

Mountains, through which it breaks near the east end of the range. It then flows southwai;d in Colorado for about 25miles, turns pack into Utah, and continues to flow in a southwesterly and southerly direction until it unites with the Grand to form the Colorado. Its 

length, measured roughly along the course, is approximately 425 miles.

14 STREAM MEASUREMENTS IN 1905, PART XI. 

The topography of the headwater region is· rugged in the extreme. The Wind River 

Range on the east and the Gros Ventre and Wyoming ranges on the northwest and west 

gradually close in as the_y extend southward, forming a basin comprising approximately 

7,450 square miles in extent above the gaging station at Green River, Wyo. The upper part 

of this basin is very narrow, but southward the valley opens out and near Fontanelle, Wyo., 

is several miles wide, with benches and rolling table-lands extending westward to the foothiJls of the Wyoming Range and eastward to the bluffs which hug the east bank of the river. 

At Green River the valley is again narrow-only a few hundred yards in width-and for some 

distance southward the river runs between bluffs standing so close together that no flood 

plain is seen. Throughout much of its course in Utah the Green flows through. a succession 

of bug, deep, narrow canyons, with walls ranging in height from a few hundred to as many 

thousand feet, separated by short valleys containing small tracts of arable lands. 

1n its upper course the Green receives as tributaries numerous streams heading in the 

Wind River, Gros Ventre, and Wyoming ranges of mountains, some of them extending so far 

back into the abrupt, ragged canyons that they dovetail with streams flowing in opposite 

directions. The most important of these tributaries are Newfork River, Big Sandy Creek, 

La Barge Creek, Fontanelle Creek, Black Fork, and Henry Fork. South of the Uinta Mountains the first large stream flowing into the Green is the Yampa, which comes in from the 

east at the point where the Green turns westward to reenter Utah after its southward journey 

in Colorado. Farther south Ashley Creek and Uinta and White rivers discharge their 

waters to the Green, Ashley Creek and the Uinta from the west and the White from the cast. 

Below this point the only tributaries of importance are Minnie Maud Creek and San Rafael 

River, which enter from the west, the latter at a point about 32 miles above the junction of 

the Green and the Grand. 

In the foothiUs and in close proximi,ty to the main ranges of the upper portion of the 

basin the soil is sand mi~ed with disintegrated granite, changing into a light, sandy loam on 

the rolling uplands, and a rich alluvial deposit in the valleys .adjacent to the waterways. 

Very little land is under cultivation, and except ih a few favored localities the only product is 

hay, which is consumed by the stock grazed on the surrounding hills. Directly south of the 

Uinta Mountains, in the region drained by Ashley Creek and Uinta, Whiterocks, and 

Duchesne rivers, large tracts of excellent agricultural land are found, much of It bemg comprised in the Uinta Indian Reservation. 

The geology of this basin is described in the Eleventh Annual Report of the United States 

Geological and Geographical Survey of the Terntories for 1877, F. V. Hayden in charge, 

pages 509-646. Information in regard to the hydrography is contained in the first to fourth 

annual reports of the Reclamation Servwe and in other United States Geological Survey 

reports. 

GREEN RIVER AT GREENRIVER, WYO. 

This ~tation was ~stablished May 2, 1895, near the pu~p house at a point about 40 feet 

below the bridge of the Umon Pacific Railroad,atGreenriver, Wyo. Since that date it has 

been maintained contmuously, except for a few months during the winter and during the 

year 1900. 

The channel is straight for about 500 feet above and 300 feet below the measuring section, 

and the banks are sufficiently high to prevent overflow. The bed of the stream is composed 

of sand. During low-water penods the entire right half of the channel is a bed of clean sand, 

shifting more or Jess each year, and the stream runs m a single channel on the left; but as the 

water rises it extends across the two channels and under the approaches of the bridge. At 

the gage there are at ordinary stages two channels and at times of flood four channels, interrupted, to some extent, by open cribs four feet wide, made by spiking heavy planks to piles 

driven into the bed of the stream, which here is sandy but stable. 
GREEN RIVER. 15 

Discharge measurements are made from the iron highway bridge about one-half mile below 

the railway bridge, as the section under the latter is unsatisfactory for the purpose. The 

initial point for soundings is a deep notch cut in the railing near the end of the. bridge on the 

left bank. 

The gage, which was observed during 1905 by William Slater, is a staff securely fastened 

to heavy submerged cribbing on the east bank of the river. The bench mark is a cross on 

the third step from the bottom of the south end of the east abutment of the railroad bridge; 

elevation 12.48 feet above the zero of the gage. It has not changed perceptibly since so 

placed.

GREEN RIVER AT JENSEN, UTAH. 

This station was established November 7, 1903. It is located at Jensen pust-office, about 

300 feet below what is known as Billings Ferry, 1.5 miles from Vernal. The nearest railroad 

station, Dragon, Utah, is about 40 miles distant. Brush Creek enters the river 1! miles 

above the station and Ashley Creek 3 miles below. 

The channel is straight for about] ,000 feet above and below the station. The right bank 

is high, is composed of gravel, and will not overflow; the left bank is low and sandy and 

covered with underbrush. The bed of the stream is sandy and shifting. There is but one 

channel at all stages. 

The first discharge measurements were made from the ferryboat, but the station was 

equipped with a cable and car during 1904. The initial point for sounrlings is the first 

white mark on the cable on the right bank. 

The gage is a vertical timber 10 feet long, braced to a cottonwood tree about 10 feet from 

the edge of the river. The gage is referred to bench marks as follows: (1) A 40-penny spike 

driven into the cottonwood tree to which the gage is attached; elevation, 10.66 feet above 

the zero of the gage. (2) A. 40-penny spike driven into the southwest corner of Mr. Billings's 

grain house about 3 feet above the ground; elevation, 25.64 feet above the zero of the gage.

GREEN RIVER AT OURAY, UTAH. 

This station was established March 23; 1904. It is located about 500 feet below the ferry 

maintained by the Government at Ouray1 Utah. The nearest town is Vernal, Utah, 35 

miles distant, and the nearest railroad station is Dragon, about 35 miles distant. 

The channel is slightly curved for ~1bout 2,000 feet above and is straight for 1,200 feet 

below the station. Both banks are fairly high and timbered. The right bank overflows for 

a short distance at high stages. The bed is composed of clean sand and is shifting. The 

stream is usually confined to one channel, which changes as sand bars are formed during 

high water. The velocity is fairly good. 

Discharge measurements are m~1de from the Government ferry cable, which is suspended 

across the river about 500 feet above the gage. The initial point for soundings is the first 

white mark on the cable on the right bank of the river. 

The gage is a staff securely driven into the river bottom and spiked to a large cottonwood 

tree that overhangs the right bank. The gage is referred to bench marks as follows: (1) A 

large nail ddven into the inside face of the tree that supports the gage rod; elevation, 13.80 

feet above the zero of the gage. (2) A large nail driven into a blaze on a root of one of a 

group of large cottonwood trees 150 feet northeast of the gage; elevation, 13.51 feet above 

the zero of the gage. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 59-60.

GREEN RIVER. 19 

GREEN BIVER AT GREENRIVER, UTAH. 

This station was established Oetober 21, 1894, discontinued in November, 1896, and reestablished February 16, 1905. It is loeated at the Rio Grande Western Railway bridge at 

Greenriver (formerly Blake), Utah, in latitude 39° north, longitude 110° 9' west, in the San 

Rafael quadrangle. 

The ehannel is straight for about 2,000 feet above and 1,000 feet below the station. Both 

banks are barren and are suffieiently high to prevent overflow. At the ferry eable the bed 

is of clay and shale and is apparently permanent exeept for a thin layer of silt or sand, whieh 

is deposited near the eenter at low stages and sluiees out at high stages. The bed at the 

railroad bridge is in the main solid roek and is probably permanent, but is rather rough in 

profile. Conditions for high-water measur~ments are unfavorable owing to the large 

masonry piers of the bridge and the high veloeity of the eurrent. The veloeity at the lowwater seetion is low. Information in regard to winter eonditions is ineomplete. 

At low and ordinary stages diseharge measurements are made from a ferryboat at a point 

400 to 500 feet above the bridge. The cable to whic.h the ferryboat is attaehed is graduated 

at 20-foot intervals with white paint. The in~tial point for soundings is the south faee of a 

blazed tree, to whieh the eable is attaehed, on the west side of the stream. High-water 

measurements are made from the lower ehord on the upstream side of the steel-truss railroad bridge. The initial point for soundings is a white zero mark across the rail on the east 

end of the bridge. 

The gage, which was read during 1905 by Frank Jaeobs, is of the ehain type, and is 

attaehed to the upper guard rail of the bridge at a point near the seeond pier from the west 

end. The length of the chain is 28.45 feet. The distanee from the outside edge of the pulley to the 3-foot mark on the gage rod is 1.85 feet. The old beneh mark established in 1894 

was on a pier, but a new bridge has since been eonstrueted and the pier changed. It was 

therefore impossible to get a definite tie to the original datum. A~tigh tie was, however, 

obtained from the old inclined gage on the shore near the pump house, and this showed the 

present datum to be 1.68 feet below the original. In view of the faet that the cross seetion 

at the gage has been ehanged to some extent by the reloeation of the bridge piers, it is 

probably impossible to establish a satisfaetory relation between the original reeords and 

those now being taken. The present beneh mark is the top of a 1 !-inch iron drift bolt set 

in the west abutment of the railroad bridge on the north side. The bolt projects about 8 

inches above the surface of the stone and is on one of the footing courses of the abutment 

about 3 feet from the top; elevation of beneh mark above the zero of the gage, 25.64 feet.

Newfork River and its tributaries drain a portion of the western slopes of the Wind River 

Range, extending from Fremont Peak southeastward to Mount Bonneville, Mount Geikie, 

and Twin Buttes. The main stream flows in a general southerly course to a point near 

Cora, Wyo., where it turns sharply to the southwest, joining Green River about 40 miles 

below. 
STREAM MEASUREMENTS IN 1905, PART XI. 

The entire length of the Newfork does not exceed 50 miles. The basin as a whole is triangular in shape and comprises approximately 1,100 square miles. Forests, in some places 

dense, cover about 300 square miles. Pines predominate, but aspens and firs are also found. 

Pine, Pole, and Boulder creeks and East.fork River are the chief tributaries of the Newfork. These are all small streams, heading far back among the high peaks of the range and 

fed by. the numerous springs and small mountain lakes with which the. region is dotted. 

Fremont, Boulder, Fayette, Half Moon, Burnt, and Meadow lakes are the largest and most 

important of these. Fremont Lake, through which Pine Creek flows, has an area of approximately 2,500 acres. The outlet is narrow and a dam at this point might be made to raise 

the water surface about 30 feet. Such a dam would probably store all the surplus waters 

of the creek. Boulder Creek flows through Boulder Lake. The outlet of this lake also is 

narrow, and a dam to raise the surface of the lake about 5 feet is in process of construction. 

In the drainage area of Pole Creek there are said to be no less than 40 small settling basins. 

The upper portion of all these streams is forested and the valleys and rolling bench lands 

are covered with sagebrush and a sparse growth of nutritious grasses. The soil of the foothill region is sandy and gravelly in character, gradually becoming a rich loam at the lower -

levels. Several ditches are taken out of Pine and Pole creeks and Eastfork River, and 

small areas of land are irrigated in a primitive way. The valley of Boulder Creek contains 

from 15,000 to 20,000 acres of the best agricultural land in the northern Green River basin. 

This could easily be watered from the creek, and diversion projects which contemplate the 

reclamation of the greater part of It are well under way. 

NE"\<VFORK RIVEU NEAR CORA, WYO. 

A temporary gaging station was established May 23, 1905, for the purpose of obtaining 

data in regard to th~ relative run-off of the stream and its tnbutaries. It is located at the 

''Pinedale Crossing," about 3 miles below Cora, Ill sec. 19, T. 34 N ., R. 104 W. 

The channel, though generally very winding, IS straight for 150 feet above and 100 feet 

below the gage. The banks are not subject to overflow. The bed of the stream is composed of cobblestones and is permanent. 

Discharge measurements are made by wading at a point 100 feet above or from a foot 

bridge 50 feet above the gage. 

The gage was read at 5 p.m. six days each week (the Sunday reading being estimated) by 

J. J. Hansen, the mail carrier between Cora and Pinedale. The gage consists of a board 

nailed to a hewn timber, firmly braced by long poles to the left bank of the stream. The 

bench mark IS the top of a stake dn ven mto the ground 10 feet northeast of the gage, opposite the 3.50-toot mark on the gage 

The statiOn was d1scontmued August 31.

PINE CREEK NEAR PINEDALE, WYO. 

Pine Creek, designated on the eariler maps as Fremont Creek, rises on the southern face 

of Fremont Peak, near the top, and flows southwestward to its point of junction with Newfork River. Its length is about 25 miles. From its source to a point about 2 miles beyond 

Fremont Lake, through which it flows, it is a winding stream having a series of falls and 

rapids, almost impassable even at low water. Its drainage area comprises 130 square 

miles, about 60 square miles being covered with forest, more or less dense. Two diversion 

ditches are taken from the stream, and together these irrigate about 2,000 acres of grass 

land. Another canal of larger dimensions is contemplated to provide water for an a_dditional 6,000 acres. 

A gaging station was established on the stream April 25, 1904. It was located about 

one-fourth mile west of Pinedale, but this location not proving entirely satisfactory, it was 

abandoned at the close of the season, and April2, 1905, it was reestablished near the Hansen 

ranch, 1 mile above Pinedale, in sec. 28, T. 34 K., R. 109 W. 

The channel is comparatively straight for several hundred feet above and below the 

·gage. The stream runs high in its banks, but does not overflow. The bed is rocky and 

permanent. There is but one channel, and this is unobstructed except during the winter 

months, wh~ ice forms. The range of gage heights seldom exceeds 2 feet. 

High-water measurements are made by means of a boat, a strong wire being stretched 

from bank to bank for use as an anchor. During low-water periods measurements are 

made by wading at a point 300 yards below the gage, where the bed of the channel isgenerally smoother. 

The gage, which during 1905 was read daily b~J. J. Hansen, is a verticallO-inch round 

timber, set 1 foot deep into the rocky bottom of the channel and braced firmly to a large 

pine tree on the right bank. The bench mark is a spike driven into the tree opposite the 

5-foot mark on the gage. 

A description of this station, with gage-height and discharge data, is contained in Water· 

Supply Paper No. 133, of the United States GeologicarSurvey, pages 60-62.

POLE CREEK AT FAYETTE, 'VYO. 

Pole Creek rises on the southern and western slopes of ~~ewfork Peak, flows southwestward, and um~es with Newfork Rtver about midway between the pmnts where Pine Creek 

and Eastfork Ri.ver jom that stream. Like the other tnbutat"Ies of the Newfork, it is a 

mountain stream, its somce of supply being the direct drainage at Its head and numerous 

small lakes and ponds, of whtch Fayette and Halfmoon lakes are the largest. The creek is 

about 25 miles m length. For the last 10 miles of its course it flows through a level or 

shghtly undulatmg valley, varying from 1 mtle to 3 miles in width, with a rich alluvial sml. 

Two dtversion dttches, which provide water for the Irngation of about 3,700 acres ~t land, 

are taken from the creek. 

The gaging statiOn was established April 22, 1904. It is located at a point opposite and 

about 300 yards distant from Fayette post-office, m sec. 9, T. 33 N ., R. 108 W. 

The channel is straight for about 50 feet above and 100 feet below the station. The 

right bank is low, IS covered with brush, and Is liable to overflow. The left bank is high 

and clean and does not overflow. The bed is composed of cobblestones and sand and _1:::~ 

stable. There is but one channel at low water; at high water there Is one main channel 

and a small slough on each side. The slope of the channel is toward the left bank, and tqe 

current is swift. Gage hetghts have a range of nearly 3 feet. The creek seldom free~ 

entirely over owmg to the veloctty of the current and the numerous adjacent sprin~. 

There are no natural obstructiOns except &uch as are formed by the accumulations of ~ee 

among the willows that fringe the banks and extend back for a considerable distance. 
26 STREAM MEASUREMENTS IN 1905, PART XI. 

At ordinary stages diseharge measurements are made by wading at a point about 200 

yards below the gage: High-water measurements are made by means of a boat swinging 

from a wire stretched taut directly across the channel from bank to bank. 

The gage, which was read during 1905 by G. N. Stadin, is a vertical timber set 1 foot 

deep i~to the cobblestone bed of the stream and firmly braced to the left bank. For use 

during high-water stages a wire gage has been attached to the vertical gage in such a way 

as to extend about 3 feet out over the stream. The gage is referred to bench marks as 

follows: (1) The top of a 3-inch stake driven firmly into the ground about 10 feet from the 

gage and marked with a copper number ''0;" elevation above the zero of the gage, 4.47 feet. 

(2) The top of a similar stake about 10 feet from the gage, marked with a copper number 

''7;" elevation, 5.02 feet above the zero of the gage. . 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 62-65.

28 STREAM MEASUREMENTS IN 1905, PART XI. 

FALL CREEK NEAR FAYETTE. WYO. 

Fall Creek, a small tributary of Pole Creek, joins the latter less than 2 miles from the point 

where it emerges from the foothills. It is fed by numerous springs and small mountain lakes 

and flows through Burnt Lake, which covers an area of 700 or 800 acres. The creek is about 

15 miles long and drains an area of 60 square miles, of which almost one-third is forested. 

The entire basin is very rough. One small ditch is taken from it, conveying water upon the 

Pole Creek flats. 

A gaging station was established April 22, 1904. It is located about 1 mile southeast of 

Fayette post-office, at the crossing of the Upper Boulder road, in sec. 10, T. 33 N., R. 108 W. 

The channel is straight for about 40 feet above and 50 feet below the station. The banks 

are high and are not liable to overflow. The bed of the stream is composed of cobblestones 

and gravel and is smooth. The current is swift except at very low water, when it becomes 

sluggish. There is but one channel at all stages. Early in 1905 some large cobblestones, 

which at low water protruded from the riffles below the gage; were removed, and the rating 

curve for 1905 is therefore slightly different from that for 1904. Gage heights have a range 

of almost 2 feet. The stream is frozen solid during the winter months. 

Discharge measurements are made at low and ordinary stages by wading, and at high 

water by means of a boat, the initial point for soundings being the left bank at the gage. At 

extreme low water a section 200 yards below the gage is chosen. 

The gage, which was read during 1905 by G. N. Stadin, is a vertical timber set in the bed 

of the stream and firmly braced to the left bank. The bench mark is a cross on the highest 

point of a stone about 1 foot in diamt>ter planted firmly in the ground 10 feet from the gage 

and surrounded by smaller stones. Elevation above the zero of the gage, 4.63 feet. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 65-67.

30 STREAM MEASUREMENTS IN 1905, PART XI. 

BOlJLDER CREEK NEAR BOULDER, WYO. 

Boulder Creek rises in the vicinity of Mounts Bonneville and Geikie, in the Wind River 

Mountains, flows westward through Boulder Lake, then turns to the southwest and unites 

with Newfork River 3 miles above the point where the latter stream is joined by the Eastfork. Numerous small mountain lakes, seattered over an area 5 or 6 miles square, contribute their drainage to the creek near its head. Boulder Lake, the largest of these, lies 

at an elevation of 7,200 feet and its water surface is estimated to cover 1,500 acres. The 

total area of the basin is 160 square miles and approximately one-third of this is timbered. 

The upper two-thirds of the basin is very rough; but the lower third is a gently sloping flat, 

which eontains 15,000 to 20,000 acres of excellent agricultural land. 

The gaging station was established April 23, 1904. It is located at the Coolidge ranch, 

about 1! miles northeast of Boulder post-office, in sec. 4, T. 32 N., R. 108 W., and is below 

all diversion ditches. In the 1904 Progress Report this station was given as Boulder Creek 

near Newfork, Wyo. 

The channel is nearly straight for about 300 feet above and below the station. The 

right bank is low and is covered with brush and small trees, but is liable to overflow for a 

short distance only; the left bank is high and can not overflow. The bed of the stream is 

composed of cobblestones and sand and is stable. There is but one ehannel at all stages, 

and this slopes toward the left bank. The current is swift at high water, but becomes 

sluggish at low stages. Gage heights have a range of about 4 feet. The stream freezes 

solid during the winter months. Early in 1905 the larger rocks and some sunken driftwood 

opposite the gage were removed, slightly ehanging the eross section and the value of the 

gage heights on the discharge curve. 

Discharge measurements are made by wading at the station until the water rises to 

about the 2-foot mark on the gage, when the wooden highway bridge, 2miles below, is used. 

The initial point for soundings is at the gage. 

The gage, which was read during 1905 by T. J. Coolidge, is a timber firmly set in the 

bed of the stream and braced to a tree and stump on the left bank. The bench mark is a 

spike driven in a stump opposite the 4-foot mark on the gage and 3 feet distant. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, of the United States Geological Survey, pages 67-69.

EASTFORK RIVER AT NEWFORK, WYO. 

Eastfork River, the southernmost as well as the largest of the tributaries of the Newfork, 

is formed by the three small creeks which drain its upper basin. Two of these, Silver and 

Willow creeks, head among the small mountain lakes about Twin Butte and on the southern 

slopes of Mount Geikie, at an elevation of about 9,000 feet; the third, Muddy Creek, is a 

spring stream and heads at a somewhat lower elevation farther to the south. The total area 

of the Eastfork basin is about 320 square miles, and perhaps 2 per cent of this is forested. 

The upper·portion of the basin is the broken, rugged country of the mountains; farther down 

the valley opens out into broad, level stretches, with a gradual slope to the west. The soil is 

a sandy loam, well eovered in its natural condition with a heavy growth of sagebrush and· a 

smaller quantity of nutritious grasses. Irrigation is practiced in a prinutive way, a few 

small diversion ditches taking water out upon lowland meadows. 

A gaging station was established April1, 1905. It is located at a point about one-third 

mile southeast of Newfork post-office, in sec. 34, T. 32 N., R. 108 W., and about onefourth mile above the county highway bridge across Eastfork, near the Noble ranch house. 

There is but one channel and the banks are not liable to overflow. The bed of the stream 

is sandy and shifting, and the section is less satisfactory than was supposed when the gage 

was installed. Gage heights have a range of about 4 feet. The bed at the highway bridge 

is less changeable and furnishes a better section than that first selected, though it il;l divided 

into three channels by the piling. The river freezes solid during the later months of the 

winter. 

During the lower stages discharge measurements are made by wading at the station, the 

initial point for soundings being the bench mark. At high water, whep_ the gage reads above 

2.5 feet, measurements are made from the highway bridge, which is a three-span wooden 

structure, resting upon piling protected by rock at the bottom. 

The gage, which during 1905 was read daily by Mrs. Cora Noble, is a vertical timber, 

firmly braced to the right bank. The bench mark is a copper "0" on the top of a post set 

in the ground 10 feet west of the gage; elevation, 5.68 feet above the zero of the gage.

Yampa River rises in Egeria Park, in the southeastern part of Routt County, Colo., runs 

in a general northerly direction to Steamboat Sprmgs, and thence westward to its point of 

junction with Green River, just east of the Colorado-Utah State boundary. Throughout 

almost its entire course it flows in a succession of open valleys alternating with deep, narrow 

canyons, the longest and deepest of the canyons being that through which it enters the 

Green. 

The drainage basin of the river lies for the ~1ost part within the boundaries of Routt 

County, which is a little larger than. the State of Massachusetts and comprises about 6,000 

square miles. Its eastern limit is formed by the Park Mountains, and the melting of the 

snows on their high peaks is the source of numerous small streams whose waters augment the 

volume of the river and foru1 its chief perennial supply~ Westward from the mountains the 

basin is largely the eroded and dissected Yampa Plateau, whose wide terraces, abrupt cliffs, 

and deep-cut gulches and arroyos are the striking features of the region. The general level 

is over 6,000 feet above sea. 
YAMPA RIVER DRAINAGE BASIN. 35 

The rocl:s of the basin are largely of sedimentary origin and embrace chiefly formations of 

Tertiary and Cretaceous periods. The soils derived from these rocks are friable and soft, 

with considerable alkali, and large tracts are covered with sagebrush. The forests in the 

mountainous portion of the basin are composed of coniferous trees, and scattered clumps of 

pinon and cedars are found in the plateau country. Weather Bureau records show the mean 

annual precipitation at the town of Lay to be 12.35 inches. 

Elk River, Fortification Creek, Elk Head Creek, William River, and Little Snake River are 

the most important tributaries of theY ampa. The upper basins of these streams are within 

the forested region, but along their lower courses are many cultivated areas. 

Irrigation in the Yampa basin is confined to low bottom lands and scattered first-bench 

lands, but a number of systems are now under consideration. 

YAMPA RIVER AT STEAMBOAT SPRINGS, COLO. 

This station was established May 3, 1904, at the highway bridge at the east end of SteamboatSpr}ngs. May 8, 1905,·it was reestablished at the new steel highway bridge, about onefourth mile below the old bridge, in sec. 17,-T. 6 N., R. 84 W. 

The channel is straight for about 400 feet above and below the station. The left bank is 

Jow, but a roadway about 8 feet high leading to the bridge prevents any overflow. The left 

bank is high and practically clean. The stream does not overflow even at extremely high 

stages. The bed is composed of royk and gravel, with some sand, and is clean and permanent. There is but one channel at all stages, obstructed to some extent by several large 

bowlders. The current is swift at high and medium at low stages. Gage heights have a 

range of about 4.5 feet. Ice conditions during the winter months render gage readings 

impracticable. 

Discharge measurements are made from the upstream side of the single-span bridge, to 

which the gage is attached. A stay line is used to keep the meter in position during measurements of high stages. The initial point for soundings is the upstream side of the left abutment, marked zero. 

A standard chain gage, which was read twice each day during 1905 by Elmer Brightman, 

is attached to the downstream side of the bridge, 35 feet from the left abutment. The length 

of the chain is 13.43 feet. The gage is referred to bench marks as follows: (1) The top of the 

west side of the left abutment of the bridge; elevation 11.50 feet above the zero of the gage. 

(2) A standard United States Geological Survey iron post, located 100 feet south of the 

left end of the old wooden bridge, one-fourth mile up the river; elevation, 15.65 feet above 

the zero of the gage. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 70--72.

This station was established April 30, 1904. It is located· on the wagon bridge 1 mile 

south of Craig, on the road to Meeker, Colo., in sec. 6, T. 6 N ., R. 90 W., just below the 

mouth of Fortification Creek and about 7 miles above the mouth of Williams River. 

The channel is straight for 250 feet above and 300 feet below the station. Both banks 

are low and overflow at extremely high stages. The bed of the stream is composed of sand, 

gravel, and cobblestones, and is permanent. There is but one channel at all ordinary stages, 

broken by the piers of the bridge; at high stages the stream flows through the culverts· at 

each end of the bridge, and the current is materially broken by the driftwood which invariably collects at the upper side of the piers. The current is swift at high, but very sluggish 

at low water. Gage heights have a range of about 6 feet during an ordinary season. Ice in 

the channel renders gage readings impracticable during the winter months. 

Pischarge measurements are made from the downstream side of the three-span tubular 

steel pier bridge. The initial point for soundings is the vertical wall of the old log abutment on the left bank, to which the gage is attached. 

_The gage, which was read twice each day during 1905 by Lawson Thompson, is a vertical 

timber 12 feet long, fastened to a pile on the old Jog abutment at the left end of the bridge. 

The gage is referred to bench marks as follows: (1) The top of a bolt marked with a cross on 

the top of the tubular steel and concrete pier on the downstream side of the left abutment

of the bridge; elevation, 14.34 feet above the zero of the gage. (2) The top of a bolt 

marked with a cross on the top of the corresponding pier on the upstream side of the bridge; 

elevation, 14.37 feet above the zero of the gage.

YAMPA RIVER NEAR MAYBELL, COLO. 

This station was established April 17, 1904. It is located at the Thornburg bridge, 10 

miles west of Maybell and 75 miles from Meeker, Colo., in sec. 19, T. 7 N ., R. 96 W. 

The channel is straight for about 300 feet abovP and 600 feet below the station. The left 

bank is low and dean and overflows to a considerable extent during high water. The right 

bank is high and clean and is not subject to overflow. The bed of the stream is composed 

of gravel and sand and is shifting. Ice conditions render gage readings impracticable during the winter months. The ordinary range of gage heights is about 6 feet. 

Discharge measurements are made from the downstream side of the two-span bridge to 

which the gage is fastened. · The initial point for soundings is the edge of the left abutment. 

The gage, which was read twice each day during 1905 by Peter Farren, is a staff fastened 

to the left downstream edge of the middle pier of the bridge. The bench mark is a United 

States Geological Survey standard bronze tablet set in the top stone of the right abutment on the downstream side; elevation above the zero of the gage, 10.79 feet. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, of the United States Geological Survey, pages 75-77.

Elk River rises in the northeastern part of Routt County, Colo., flows southward, and 

joins Yampa River 6 miles below Steamboat Springs. The drainage basineomprises the 

western slope of the Park Range and the greater part of it is mountainous, but there is some 

open prairie land along the river and its larger tributaries. Much of this prairie land is under 

cultivation, being irrigated by numerous ditches from the streams. Hay is the principal 

crop, but in the lower portion of the valley cereals are raised to some extent. The higher 

portions of the basin are covered by heavy forests of pine and spruce. Precipitation consists principally of snow during the winter months. 

The gaging station was established May 2, 1904. It is located about 2 miles southeast of 

Trull post-office, on the stage road between Steamboat Springs and Hayden, Colo., in sec. 

32, T. 7 N ., R. 85 W., and is below all tributaries. 

The channel is straight for 100 feet above and for 300 feet below the station. Both 

banks are low but are not liable to overflow except at very high stages. The bed of the 

stream is composed of rock and is permanent. There is but one channel at all stages. The 
42 STREAM MEASUREMENTS IN 1905, PART XI. 

current is swift at all times and exceedingly so at high water. Ice conditions render gage 

readings impracticable during the winter months. Gage heights have an ordinary range of 

about 4 feet. 

Discharge measurements are made from the downstream side of the single-span bridge 

to which the gage is attached. The initial point for soundings is the vertical wall of the 

masonry abutment at the left end of the bridge on the downstream side. There is also a 

stay-wire about 50 feet above the bridge for holding the meter at high stages. 

The gage was read twice each day during 1905 by H. W. Hitchins. The original gage was 

timber, placed vertically near the right end of the bridge. This was replaced June 22, 1904, 

by a standard chain gage, referred to the same datum. The chain hangs from a point 25 

feet from the initial point for soundings on the downstream side of the bridge. The length 

of the chain is 16.20 feet. The bench mark is a United States Geological Survey standard 

aluminum bench-mark tablet, set on the downstream end of the masonry abutment at the 

right end of the bridge; elevation, 15.995 feet above datum of gage. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply PaperNo. 133 of the United States Geological Survey, pages 78-80.

FORTIFICATION (;REEK AT CRAIG, COLO. 

Fortification Creek rises near Mount Walba, in northeastern Routt County, Colo., flows 

westward, southeastward, and southwestward, and joins Yampa River at Craig. 

The gaging station was established June 12, 1905. It is located at the highway bridge 

about one-fourth mile east of Craig, Colo., in sec. 6, T. 6 N., R. 90 W. 

The channel is straight for about 50 feet above and 20 feet below the station. The right 

bank is lo~ and overflo~s at very high water; the left bank is high. The bed of the stream is 

composed of sand and silt and is shifting. There is at all stages but one channel, which 

is dry late in the summer. 

Discharge measurements are made from the downstream side of the single-span bridge to 

which the gage is fastened. The initial point for soundings is the lower side of the bridge, 

flush with the west abutment. 

The gage, which was read twice each day by H. W. Rose, a civil engineer who lives at the 

station, is a vertical staff, fastened to the east abutment on the lower side of the bridge. 

A measurement made June 12,1905, by H. G. Graham, gave the following results: Width, 

51 feet area., 84 square feet; mean velocity, 2.52 feet per second; gage height, 4.40 feet; 

discharge, 212 second-feet.

"\VILLIAMS RIVER AT HAMILTON, COLO. 

Williams River rises in the White River Plateau, the highest portion of which reaches an 

elevation of 11,000 feet. It flows northwestward and unites with Yampa River about 7 

miles below Craig. It is joined by numerous small trib~taries which drain portions of the 

Williams River Mountains on the east and the Danforth Hills on the south. The largest of 

these tributaries is Marapos Creek, which rises near the Milk Creek divide, flows eastward, 

and joins Williams River at Hamilton. The entire drainage area is hilly or mountainous, 

and throughout the upper portion of it there are extensive forests, mainly of white pine 

and spruce. Farther down the forests give way to a growth of willows and cottonwood along 

the river bottom and oak brush and shrubbery on the hillsides. Agriculture is confined to 

the narrow valley extendi:t'lg along the river and some of its largest tributaries. Wild hay is 

the principal crop, and cattle raising is carried on extensively. The precipitation consists 

chiefly of snow during the winter months. The maximum discharge occurs during the latter 

part of May. 

The gaging station was established 4pril29, 1904. It is located at the highway bridge at 

Hamilton, on the stage road from Meeker to Craig, Colo., about 17 miles from Craig, in sec. 

20, T. 5 N., R. 91 W. 

The channel is straight for about 150 feet above and 100 feet below the station. The right 

bank is high, rocky, and clean; the left bank is low and wooded, but does not overflow except at extreme high stages. The bed of the stream is composed of cobblestones and gravel, 

but is shifting. There is but one channel at all stages. Gage heights have an ordinary range 

of about 3 feet. During the winter season ice obstructs the channel to such an extent that 

gage readings are impracticable. 

Discharge measurements are made from the lower side of the single-span bridge to which 

the gage is attached. The initial point for soundings is the downstream end of the vertical 

log abutment at the left end of the bridge. 

The gage, which during the early part of 1905 was read twice each day by Mrs. Thomas 

Hamilton, was a 14-foot timb~r, driven vertically into the bottom of the river, with the upper 

end fastened to the lower side of the bridge. May 21, 1905, a standard chain gage was installed, the datum being the same as that of the original gage. The length of the chain is 

14.94 feet. The gage is referred to bench marks as follows: (1) A nail driven into the top 

log at the northeast corner of the left abutment of the ~idge; elevation, 12.22 feet. (2) The 

head of a nail driven into a root on the west side of a small cottonwood tree about 25 feet 

from the left end of the bridge and just east of the road; elevation, 10.08 feet. (3) A nail 

driven into the southeast corner of the foundation of the blacksmith shop about 25 feet 

from the left end of the bridge; elevation, 10.08 feet. ( 4) A United States Geological Sur-· 

vey standard iron post at the southeast corner of the wagon bridge; elevation, 10.77 feet. 

Elevations are above the zero of the gage. 

A description of this station, with gage-heiglit and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 80-82.

MILK CREEK NEAR AXIAL, COLO. 

Milk Creek rises in the northeastern part of Rio BlancoCounty,Colo.,flows northwestward, 

and enters Yampa River about 20 miles below Craig. 

·The gaging station was established April 20, 1904. It is located at the highway bridge 

about 4 miles below Axial, Colo., in sec. 19, T. 4 N ., R. 92 W. 

The channel is straight for 75 feet above and 50 feet below the station. Both banks are 

high and clean and do not overflow. The bed of the stream is composed of sand, and shifts 

to such an extent that it is difficult to obtain a good rating curve. There is but one channel 

at all stages, the current being swift at high and medium at low water. Gage heights have a 

range of about 3.5 feet during an ordinary season. Ice conditions render gage readings 

impracticable during the winter months. 

Discharge measurements are made from the lower side of the single-span bridge to which 

the gage is attached. The initial point for soundings is at the left end of the bridge, at the 

water's edge, on the downstream s~de. 

The original gage, which was read once each day during 1905 by Mrs. 0. M. Hoback, who 

lives three-fourths of a mile east of the station, is a vertical staff, 10 feet long, driven 2 feet 

i_nto the sandy bed of the stream, the top being nailed to the bridge timbers. The gage is 

referred to bench marks as follows: (1) A nail driven about 4 inches above the ground into the 

east side of a telephone pole 25 feet south of the bridge; elevation, 10.96 feet. (2) A nail 

driven into the north side of a 12-inch pile at the northeast corner of the bridge; elevation 

10.08 feet. (3) A United States Geological Survey standard iron bench-mark post, set 

July 21, 1904, about 50 feet southeast of the gage rod; elevation 12.33 feet. Elevations are 

above the zero of the gage. 

This station has been discontinued. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, of the United States Geological Survey, pages 83-85.

1,483 

White River rises in Trappers Lake, which lies at an elevation of 9,500 feet above sea level 

in a small mountain basin of the White River Plateau in eastern Garfield County, Colo.; 

thence it flows westward to its point of junction with Green River in west-central Uinta 

County, Utah. Throughout its course it occupies a narrow, mountainous valley, with alternating parks and canyons, entering the longest and deepest of the canyons, in which it continues to its mouth, about 8 miles east of the Colorado-Utah State line. 

The basin comprises an arid, broken, and much eroded plateau region, which t~pographically 

is a continuation of the Grand River Mesa south of Grand River. The headwater portion 

covers the greater area and is called the White River Plateau; below this and to the south is 

the Roan or Book Cliffs Plateau. Fragmentary plateaus also occur along the northern side 

of the river. 

Mumerous small streams, among which are Marvine Creek and South Fork, join the White 

in the upper, mountainous portion of the basin. Douglas, Piceance, and Evacuation Creeks, 

draining the Book Cliffs Plateau, enter White River from the south. In the spring these 

creeks carry considerable water, derived mainly from melting snow, but in the summer they 

are very nearly dry. 

'I'he rocks of the basin are largely of sedimentary origin, and west of the Great Hog Back 

the relief features produeed by erosion are characteristic and remarkably uniform. The 

shales and marls, wherever sufficiently compact, have been made into steep, inaccessible 

bluffs, and sandstones have become vertical cliffs. The stream channels are deeply cut, and 

the flood waters carry a large amount of silt. The soils derived front these rocks vary from 

sandy to adobe texture, have praetically no organic ingredients, and are very friable, and 

wind and water are constantly breaking them up and transporting them lower down in the 

basin each year. 

Short grasses cover the tops of many of the ridges, while juniper and pinon overgrow their 

sides. Greasewood and sage brush occur extensively over dry valleys and along plateaulike ridges. In the moist valleys willows and cottonwoods grow in dense masses. In the 

White River Forest Reserve, which extends over. the greater portion of the headwaters, and 

in general at elevations above 7,500 feet, quaking aspens and 'spruce predominate, while 

along the plateaus pinon and cedars are more in evidence. 

The mean annual precipitation recorded at Meeker is 15.9 inches; farther west and at 

lower elevations it ia undoubtedly much less. 

Numerous ditches along the main stream and some of its tributaries divert water for irrigation, which has been praeticed in a desultory way for many years. Native hay and kindred 

products are the chief agricultural staples in the upper part of the area, while grains, grasses, 

alfalfa, and some fruits are grown in the lower valleys. 
50 STREAM- MEASUREMENTS IN 1905, PART XI. 

NORTH FORK OF WHITE RTVER NEAR BUFORD. C~OLO. 

This station was established July 28, 1903. It is located at the county bridge at Rawson's 

ranch, below the mouth of Marvine Creek, 7 miles from Buford, the nearest post-office, and 

32 miles from Meeker, Colo. 

The channel is straight for 200 feet above and 300 feet below the station. Both banks are 

high and are not liable to overflow. The bed of the stream is rocky and is free from vegetation. There is but one channel at all stages, broken by the two narrow bridge piers. The 

current is swift. 

Discharge measurements are made from the three-span highway bridge to which the gage 

is attached. The bridge has a total span of 85 feet. The initial point for soundings is the 

edge of the abutment at the south end of the bridge. 

The gage, which is read twice each. day by H. N. Rawson, is a timber spiked to the lower 

side of the first pier from the south end of the bridge. It reads from 1 foot to 9 feet. The 

gage is referred to bench marks as follows: (1) The top of a bolt on the bridge nearest the 

gage; elevation, 11.51 feet. (2) A spike in the trunk of a large cottonwood tree at the 

southeast corner of the bridge; elevation, 7.46 feet. (3) A spike in one of the abutment 

logs at the end of the upper sill at the southwest corner of the bridge; elevation, 7.88 feet. 

Elevations are above the zero of the gage.

52 STREAM MEASUREMENTS IN 1905, PART XI. 

SOUTH FORK OF WHITE RIVER NEAR BUFORD. COLO. 

This station was established July 25, 1903. It is located at the county bridge at the 

lower end of a section of the river known as "Stillwater," about 7 miles from Buford, the 

nearest post-offic{'., and about 30 miles from Meeker, Colo., in T. 1 S., R. 91 W. 

The channel is straight for 50 feet above the station and for 300 feet below. Both banks 

are high and are covered with grass and sagebrush. The bed of the stream below the " Stillwater" and at the station is covered with bowlders, some of which are 2 or 3 feet in diameter. 

There is but one channel at all stages, broken by the middle pier of the bridge, and the current is swift. During the winter months ice obstructs the channel to such an extent that 

gage readings are impracticable. 

High-water measurements are made from the bridge, which makes an angle of 20° with 

the normal to the stream. This is taken into account in making the measurements. The 

initial point for soundings is the edge of the abutment at the west end of the bridge. At 

low water, measurements are made by wading. 

~-· ·The gage, which was read twice each day during 1905 by Claud Dobbs, is a 10-foot vertical 

timber spiked to the upper side of the middle pier. The gage is referred to bench marks as 

follows: (1) The first bolt on the bridge east ~f the gage; elevation, 11.95 feet. (2) A 

spike in one of the logs of the abutment at the southwest corner of the bridge; elevation, 8.57 

feet. (3) The corner of a large rock 30 feet west of the bridge and north of the road; elevation, 13.14 feet. (4) The top of a pyra.mid-shaped rock on the east side of the river below 

the bridge 41 feet distant from the northeast bolt on the bridge tie and projecting 8 inches 

above the ground; elevation, 7.02 feet. Elevations are above the zero of the gage. The 

elevation of the station above sea level, as determined by aneroid barometer, is 7,400 feet.

This station was established May 24, 1901. It is located about one-half mile above the 

town of Meeker, at a point where a wagon bridge crosses the stream, on the ranch of L. F. 

Van Cleave, in sec. 25, T. 1 N., R. 94 W. 

The channel is straight for 500 feet above and below. the station. Both banks are high 

and not liable to overflow. The bed of the stream is composed of gravel and cobblestones and seems to be permanent. There is but one channel at all stages. The current is 

always swift and is extremely so at high water. G~ge heights have an ordinary range of 

about 2.5 feet. During the winter months ice obstructs the channel to such an extent that 

gage readings are impracticable. 

Discharge measurements are made from either the upstream or downstream side of the 

bridge, the initial point being at the left end. 

The gage, which was read twice each day during 1905 by L. F. Van Cleave, consists of a 

vertical timber nailed to the left abutment of the bridge on the downstream side. The gage 

is referred to bench marks as follows: (1) The top of a bolt in the truss immediately above 

the gage rod; elevation, 10.83 feet above the zero of the gage. (2) A standard United States 

Geological Survey iron post, located 30 feet north of the north end of the bridge; elevation, 

8.807 feet above the zero of the gage. ...

WHITE RIVER NEAR RANGELY, COLO. 

This station was estabiished April14, 1904. It is located at the wagon bridge 1 mile west 

of Rangely, Colo., in sec. 3, T. 2 N., R. 102 W. 

The channel is curved at the station and the bridge makes an angle of 15° with the radius 

of the curve. The right bank is high and clean and does not overfl~w; the left bank is low 

and clean, and overflows at high stages. The bed of the stream is composed of sand and 

gravel and is shifting. There is but one channel at all stages. There is an island about 200 

feet above the bridge which breaks the current and causes it to run diagonally across the 

channel in various directions. The current is swift at all times and at high stages surges 

rapidly. Conditions at this station are unfavorable for accurate measurements, but there 

is no other available point on this section of the stream. 

Discharge measurements are made from the downstream side of the single-span bridge, to 

which the gage is attached. The initial point for soundings is the vertical wall of the right 

abutment. 

The gage, which was read twice each day during 1905 by Miss Zinni::~ Coltharp, is a 12-foot 

timber fastened .to the downstream side of the right abutment of the bridge. The bench 

mark is a United States Geological Survey standard aluminum tablet, set on the top stone 

of the right abutment on the downstream side of the bridge; elevation, 16.86 feet above the 

zero of the gage. 

This station was abandoned December 31, 1905. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 99-101.

Marvine Creek rises in Marvine Lake, in the southeastern part of Rio Blanco County, 

Colo., and flows northwestward to its point of junction with White River. 

The gaging station was established July 27, 1903. It is located at a point where the 

stream is crossed by a large aspen log. The station is 10 miles from Buford, the nearest 

post-office, and is about 35 miles from Meeker. 

The channel is 30 feet wide and is stmight for 100 feet above and below the station. The 

right bank is sloping and will overflow for 10 or 15 feet at high water. The left bank is steep 

and is not liable to overflow. Both banks are covered with thick brush. The bed of the 

stream is covered with bowlders and is free from vegetation. The channel is divided into 

two parts by a large sunken log, which supports the middle of the footbridge. The current 

is swift. 

Discharge measurements are made from the log which spans the stream at the gage. The 

initial point for soundings is at the gage rod. 

The gage, which is read twice daily by James Fitzgerald, 'is a vertical 5-foot timber, 

fastened to the lower side of the foot log, which.is used as a bridge. It is referred to bench 

marks as follows: (1) The top of a rock 22 feet west of the gage rod; elevation, 4.62 feet. 

(2) The top of a triangular-shaped rock betwe(;ln two spruce trees on the west bank; elevation, 6.01 feet. (3) The top of a large rock 30 feet northwest of the gage; elevation. 4.61 

feet. Elevations are above the zero of the gage.

Duchesne River rises in the high peaks of the Uinta and Wasatch mountains, flows in a 

general southeasterly direction, and enters Green River 3 miles above the mouth of the 

White. It is a very crooked stream, swinging back and forth across its valley, its c.ourse 

marked by a thick line of cottonwoods. 

The principal tributaries of the Duehesne are Strawberry, East, and Lake creeks and 

Uinta River .. From the mouth of Strawberry Creek down to Lake Creek the valley of the 

Duchesne averages 2 miles in width and is bordered on both sides by sandstone bluffs 

approximately 200 feet high. The cliffs on the northern side of the river are capped hy a 

heavy deposit of coarse river gravel and eobblestones. 

Strawberrjr Creek, the main upper tributary of the Duchesite, drains an area of 1,166 square 

miles. The stream rises in the Uinta Mountains and the run-off is derived chiefly from 

matting snow except during the late summer, when the flow comes from small springs well 

distributed over the entire drainage basin. Numerous tributaries enter the stream, particularly from the nor·th and west, Indian, Bryants Fork, Mud, Horse, Sugar Springs, and 

Co-op creeks being the principal ones. They are all short and fall rapidly until they reach 

the valley, through which they flow sluggishly in well-defined channels. The main stream 

traverses the valley from north to south and is very sluggish. Very little sediment is carried 

by the stream at any stage. The average elevation of Strawberry Valley is 7,500 feet, 

which is rather high for agricultural pmposes but is splendidly adapted to grazing. 

Indian Creek, on which a gaging station was maintained during 1905, drains a small portion 

of the southern slopes of the Uinta Mountains. Its basin comprises smooth, rolling hills, 

fairly well timbered with pine and aspen. The normal flow is derived chiefly from springs. 
DUCHESNE RIVER DRAINAGE BASIN. 61 

The greater part of the precipitation is in the form of snow, which covers the ground for six 

or eight months each year. 

Uinta River and its principal tributary, Whiterocks River, have their sources in a series 

of lakes in the Uinta "Mountains, fed by the snow that exists the year round in the canyons 

and on-the high slopes. The upper drainage ar~a of these streams is very mountainous and . 

difficult of access. After leaving their canyons, 7 or 8 miles above the Indian agency at 

Whiterocks, the rivers flow southeastward, uniting in various channels between the agency 

and Fort Duchesne, from which point they flow in one channel, entering Duchesne River 

6 miles below, near the Ouray Indian school. Pole, Farm, and Dry Gulch creeks are small 

tributaries of the Uinta. 

STRAWBERRY CREEK IN STRAWBERRY VALLEY, UTAH. 

This station was established May 2, 1903. It is located in the canyon about one-fourth 

mile above the junction of Strawberry and Indian creeks, and is somewhat inaccessible, the 

nearest settlement being Heber, 40 miles away. The chief object of the station is the 

determination of the amount of water available for storage in Strawberry Valley. 

The channel is straight ior about 600 feet above and 400 feet below the station. The 

banks are wooded and are sufficjently high to prevent overflow. The bed of the stream is 

composed of gravel and during the summer months is overgrown with moss and weeds. 

The current is sluggish. The stream is frozen during the winter months. 

Discharge measurements are made by means of a cable and car of regular form. The 

initial point for soundings is the first metal tag on the tagged wire at the left bank. 

Gage readings and discharge measurements during 1005 were made by T. C. Callister. 

The original gage was of the vertical type and was used until September, 1904, when a new, 

inclined gage was established at the same locality, about 1,000 feet above the eable. The 

datum of the new gage is the same as that of tb.e old. The bench mark is a large sandstone • 

bowlderS. 82° E. 175 feet from the gage, 12 feet from the bank of the river, and projecting 

about 3 feet above the ground. It is marked'' Rec. Ser. B. M. No.7;" elevation, 19.15 feet 

above the zero of the gage, and 7,496 feet above sea level. July 2, 1905, a low-water station 

was established at a riffle about 200 feet below tbe regular gage, where the velocity is sufficiently high to prevent the growth of vegetation, which interferes seriously with the results 

at the regular station during the summer months. The gage at this point is a vertical staff 

driven into the stream bed and is referred to bench mark No. 7, above described, its zero 

having an elevation of 19.93 feet. The annual discharge at this station is therefore repre-

.sented by two discharge curves. · 

Beginning April 15, 1905, evaporation and precipitation observations were made at a 

• point near the station. The evaporation records are obtained by means of a 4 by 4 hy 4 

foot metallic tank set in the ground with its top about 3 inches from the surface. The 

equipment used in obtaining the precipitation reeords is of the standard form used by the 

United States Weather Bureau stations and was furnished by Doetor Hyatt, direct.or of 

the Utah division of the United States Weather Bureau. The results of the expermients 

are shown in the following tables:

NoTE.-Gage heights after July 2 refer to new gage at riffle, as the old gage heights were unreliable after 

that date on .account of growing moss. 

November 23-26 there was ice along the edges but the flow was unobstructed. November 27-28 back 

water caused by ice. November 29 to December 31 the creek was frozen completely over. Gage heights 

are to water surface.

This station was established April 5, 190.5. It is located in the canyon about 250 feet 

above the junction of the creek with Strawberry Creek. It is about 1 mile below the point 

where Indian Creek leaves Indian Creek Valley and enters the canyon, and is 40 miles 

from Heber, the nearest post-office. The records will show the amount of water that can 

be diverted from Indian Ct·eek into the Strawberry Valley storage reservoir. 

The channel is straight for about 25 feet above and below the station. The right bank 

is vertical for about 1! feet above the bed and then slopes gradually upward; the left bank 

slopes irregularly from the bed. Both hanks are sufficiently high to prevent overflow. 

The bed of the stream is smooth and rocky and is not liable to shift. A slight growth of 

moss occurs in the summer, but does not interfere with ,the rating curve to any great extent. 

The velocity is medi.um and the discharge ranges from 20 to 100 second-feet. Definite 

information in regard to winter conditions is lacking. 

Discharge measurements are made from two poles laid across the stream. The initial 

point for soundings is at the right bank. 

The gage, which was read during 1905 by the men at the Reclamation Service"camp in 

Strawberry Yalley, under the direction of T. C. Callister, is a large stake driven into the 

bed about 180 feet above tht: measuring section. It is referred to a bench mark consisting 

of a cross on a large sandstone bowlder 50 feet south of the river; elevation, 16.28 feet above 

the zero of the gage and 7,480 feet above mean sea level.

PRICE RIVER DRAINAGE BASiiT. 67 

PRICE RIVER DRAINAGE BASIN, 

PRICE RIVER NEAR HELPER, UTAH. 

Price River rises in the Wasatch Mountains, in the southeastern part of Utah County, 

flows in a general southeasterly direction, and unites with Green River at a point about 14 

miles above Greenriver, Utah. The main source of supply is the snow in the upper reaches 

of the basin, where elevations range from 8,000 to 9,000 feet. The region is extremely 

rough and rugged. The principal rock is a loose and badly disintegrated sandstone. There 

is but little soil and practically no vegetation except for small groves of scrubby cedar and 

a few scattered pines. The original scanty underbrush and grass have been almost entirely 

tramped out by sheep and cattle. The river is subject to floods in the spring and early 

summer, duri,ng which time it carries immense quantities of sediment. Gordon and Pleasant creeks are the main tributaries. They are both short, steep streams and enter the river 

from the west almost at right angles. 

The gaging station was established February 21, 1904. It is located on the upper side 

of the ford near the settlement of Spring Glen, about 3 miles south of Helper, Utah, and 

350 feet west of the main line of the Denver and Rio Grande Railroad. 

The channel is straight for about 125 feet above and 400 feet below the station, and the 

banks are sufficiently high to prevent any overflow. The bed of the stream is composed of 

fine gravel and sand and shifts slightly, especially during high water. Information in 

regard to winter conditions is incomplete. 

Low-water measurements are made by wading. The initial point for soundings is a 2 by 4 

inch post driven in the left bankS. 8° W., 2! feet fwm the gage. The ·course of the sec.tion 

is N. 44 ° W. A 2 by 4 inch post marks the position of the gaging station on the right 

bank.. Measurements during high water are impossible, as there is no provision for crossing 

except by wading. 

The gage, which was read daily during 1905 by John Tryon, is a staff driven into the 

stream bed and supported at the top by a timber buried in the bank. The gage is referred 

to bench marks as follows: (1) A Standard United States Geological Survey. cap cemented 

in a sandstone bowlder embedded in the bank at a pointS. 65° E. 23 feet from the gage; 

elevation, 12.55 feet above the zero of the gage, and so marked. (2) A cross chiseled on a 

large bowlder embedded in the bankS. 6° E. 19.2 feet from the gage, marked "B. M.;" 

elevation, 11.19 feet above the zero of the gage. 

A description of this station, with gage height and discharge data, is contained in WaterSupply Paper No. 133 of the United States Geological Survey, pages 128-130.

GRAND RIVER DRAINAGE BASIN. 

AREA AND EXTENT. 

Grand River and its tributaries drain an area comprising approximately 26,180 square 

miles, of which 22,290 are in Colorado and the rest in eastern Utah. East and southeast the 

basin is limited by the high ranges of the Continental Divide, which separate it from the 

basins of the Platte and the Arkansas rivers. On the north are the White River and Book 

Cliffs plateaus, while westward it extends to the canyon district of the Colorado . 

The tributaries include innumerable small creeks and five large streams, viz, Blue, Eagle, 

Roaring Fork, Gunnison, and Dolores _rivers. 

In the following account of the work of the United States Geologieal Survey in this region 

during 1905 the basin has been subdivided, the main river being described first and the 

tributaries afterwards in their order, from the head down. 

GRAND RIVER. 

DESCRIPTION OF BASIN. 

Grand River rises on the western slopes of the Rocky Mountains among the high peaks of 

the Front Range, flows in a general southwesterly direetion across Colorado into Utah, and 

unites with Green River to form the Colorado. From source to mouth the total distance 

traversed is about 350 miles. 

In most respects the Grand is a typical mountain stream, flowing throughout its course in 

a succession of deep canyons, with precipitous and ofttimes perpendieular walls varying in 

height up to 3,000 feet. above the water's edge, alternating with long, narrow, fertile valleys. 

The headwater region, eomprising approximately 50 per cent of the basin, eonsists of a 

long stretch of the weste:r:n portion of the Continental Divide, extending from the northcentral portion of Colorado s~utpward nearly to the Colorado-New Mexico line, a distance of 

260 miles, and separating the waters of the Grand from those of the Platte and Arkansas 

basins. The area is extremely rugged, elevations ranging from 7,000 to 14,000 feet. Gradients are steep, stream channels are numerous, and tributaries are rapid, the fall varying from 

20 to 150 feet. The streams of this region derive their waters chiefly from the snow masses 

on the Continental Divide and furnish the perennial discharge of the Grand. The intermediate or middle portion of the basin, consisting largely of broken and scoured plateaus of sedimentary origin, contributes a relatively small amount of the run-off, the tributaries being 
70 STREAM MEASUREMENTS IN 1905, PART XI: 

few and, with the exception of Gu.nnison River, insignificant. The lower portion of the 

basin, immediately adjacent to the Colorado-Utah State line, is an arid, much eroded region, 

furnishing an appreciable run-off, which carries a large amount of sediment. 

The largest tributaries of the headwater region are Frazer, Williams Fork, Troublesome, 

Blue, and Muddy rivers, which add their waters to the Grand before it leaves Middle Park. 

Eagle River comes in near Eagle, just above the point where the river enters Grand River 

Canyon, and Roaring Fork unites with it just below the mouth of the canyon at Glenwood 

Springs. At Grand Junction, Colo., the river receives t~e waters of its largest tributary, 

Gunnison River, and thereafter no other stream of importance enters until the Dolores comes 

in, 15 miles west"of the Utah boundary. 

A peculiar feature of the drainage is what might be termed its one-sided nature, practically 

all its important tributaries entering the river fr~m the east. That part of the basin lying 

north and west of the Grand is much less extensive in area, is lower, and is generally broken 

and barren, and a considerable portion of the waters of its streams is diverted for irrigation. 

The geological formations of the basin range from the granite and masses of igneous 

origm on the crest of the Continental Divide to the younger and less resistant sedimentary 

rocks of the plateau region. The soils of the upper basin, though shallow, generally contain considerable organic matter; those of the intermediate basin are largely decomposed 

and disintegrated sedimentary rocks. in the lower basin the soils consist of adobe clays 

and sandy loams, which grade imperceptibly from one to the other. The scant vegetation 

of the lower basin renders soil erosion large. 

The mountainous portion of the basin is still well covered with forests of spnwe, quaking 

aspen, cedar, and pinon, and the forestation of the intermediate basin is fair. The controlling vegetation of the lower basin is sagebrush, chico, and cactus pads, with scattered 

pines, cedars, and pinons. 

The precipitation ranges from 5 to 10 inches in the lower basin, 10 to 20 inches in the 

intermediate region, and 20 to 30 inches in the headwater region. By far the greater part 

of this is in the form of snow. 

Nat ural storage within the basin is limited to a few small, high, mountain lakes. The 

stream channels of the upper basin are bordered to some extent by fiat bottom lands, which 

are used as meadows and which are irrigated by a large number of small ditches. In the 

intermediate basin are a few small reservoirs storing snow and flood waters. A immber of 

pumping plants also draw upon this district. Irrigation is extensively practiced in the 

Uncompahgre, Gunnison, and Grand valleys, and a large project now under constmction 

by the Reclamation Service will require 1,200 second-feet of the discharge of Gunnison 

River. The immense power possibilities of the Grand are at present but little developed. 

NORTH FORK OF GRAND RIVER NEAR GRAND LAKE, COLO. 

This station was established July 29, 1904. It is located at the highway, bridge between 

Grand Lake and Hot Sulphur Springs, Colo., about 3 mires southwest of Grand Lake postoffice, in T. 3 N., R. 76 W. The nearest railroad station is at Granby, on the Denver, 

Northwestern and Pacific, 15 miles distant. 

The channel is straight for about 500 feet above and for 150 feet below the station. Both 

banks are about 2 feet high and are covered with heavy sod, willows, and scattered pine 

trees. The ground slopes upward from the top of the banks rather abruptly, so that even 

at very high stages the overflow is confined to a comparatively narrow channel. The bed 

of the stream at the station and for a considerable distance above and below is covered 

with large bowlders, which at high water cause a boiling and wave motion and at low stages 

eddies and in some places dead water. The channel is very rough and has a great fall. 

There is but one channel at all stages. The ordinary range of gage heights is about 3 feet. 

Gage readings are impracticable during the winter months owing to the formation of ice 

at the rod. The section is not entirely satisfactory, but it is the best available. 
GRAND RIVER. 71 

Discharge measurements are made at the higher stages from the downstream side of the 

single-span wooden bridge to which the gage is attached. The initial point for soundings 

is a 10-penny nail driven into the bridge floor over the north face of the right abutment 

and marked zero with black paint. 

Tlie gage, which was read twice each day during 1905 by G. W. Carr, is a staff attaehed 

vertically to the downstream edge of the right abutment of the bridge. The gage reads· 

from 2 to 10.3 feet, the 2-foot mark resting on the becl of the stream. The bench mark is 

a 10-penny nail driven into a notch cut in the northeast root of a 12-inch pine tree which 

stands- at the right end of the bridge on the downstream side; elevation, 8.36 feet above 

the zero of the gage. The elevation of the station above sea level is about 8,400 feet. 

A description of this station with gage-heights and discharge data is contained in WaterSupply Paper No. 133, United States Geological Survey, pages 130-132.

This station was established July 3,1, 1904. It is located at the footbridge at the west end 

of Grand Lake, about one-half mile south of Grand Lake post-office, Colo., in sec. 6, T. 3 N., 

R. 75 W. The nearest railroad station is 18 miles distant, at Granby, on the Denver, Northwestern and Pacific Railway. 
GRAND RIVER. 73 

The channel is straight for about 300 feet above and for 150 feet below the boat station. 

Both banks are about 3 feet high, and their level tops are covered with white pine trees. 

The stream does not overflow at this point, which is one-fourth mile below the gage and 

outlet. · The. current is swift at high water and medium at lower stages. The bed of the 

stream is composed of gravel and eobblestones and is firm and free from vegetation. At 

the gage both banks are low and are liable to overflow. There is but one channel at all stages. 

Gage heights have an ordinary range of 2.5 feet. Ice eonditions render gage readings 

impracticable during the winter months. 

High-water measurements are made from a boat at a ford about one-fourth mile below 

the gage. Points for soundings are marked at 5-foot intervals by tin tags fastened to a wire 

stretched across the stream 50 feet above the ford. The initial point for soundings is the 

tree to which the wire is fastened on the right bank. At ordinary and low stages measurements are made by wading at convenient points below the gage. 

The gage, which was read twice each day during 1905 by J. W. Davies, is a staff attached 

vertically to the southeast corner of the seeond pier from the north end of the footbridge, 

the 2-foot mark resting on the bed of the stream. The gage is referred to bench marks 

as follows: (1) A cross on the top of a large granite bowlder 85 feet south of the left bank 

of the outlet and 40 feet west of the lake, marked with black paint "U.S. G. S. B. M." 

elevation, 12.05 feet above the zero of the gage. (2) A eross cut in the top of a granite 

bowlder 1,198 feet north from the initial point for soundings and marked ''B. M. ;"elevation, 

14.93 feet above the zero of the gage. Elevation above sea level is about 8,500 feet. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pages 132-134. ·

GRAND RIVER. 75 

NORTH INLET TO GRAND LAKE AT GRAND LAKE, COLO. 

This station was established August 3, 1905. It is located at the footbridge which crosses 

the stream about 100 yards north of the mouth and 300 yards east of Grand Lake postoffice, in sec. 5, 'l'. 3 N., R. 7.r'i W. 

The channel is straight for 300 feet above and for 200 feet below the station. The right 

bank is low, is covered with grasses and scattered willows and white pine trees, and at high 

stages overflows to a considerable extent. The left bank is high and is covered with a dense 

growth of white pines and underbrush. The bed of the stream is composed of large cobblestones and gravel and is permanent. There is but one channel at all ordinary stages, 

broken by the middle pier of the bridge. The current is swift at high and medium at low 

water. 

High-water measurements are made from the upstream side of the two-span footbridge. 

The initial point for soundings is a 40-penny nai·I driven in the top of the west end of the 

north stringer of the bridge, 97 feet from bench mark No.2. The point is marked with 

black paint. Low-water measurements are made by wading at convenient points above 

the bridge. · 

The gage, which was read twice each day during 1905 by J. Cairns, is a 4-foot timber fastened to the west face of the outer pier of the bridge. It is referred to bench marks as 

follows: (1) A 40-penny nail driven horizontally in the west face of a white pine tree 8 inches 

in diam~ter located on the left bank of the stream, 20 feet northeast of the east end of the 

bridge, marked "U. S. B. M.;·'' elevation, 5.32 feet above the zero of the gage. (2) A 

40-penny nail driven horizontally in the east face of a white pine tree 1 foot in diameter 

located on the right bank of the stream 97 feet west of the initial point for soundings; elevation, 4.43 feet above the zero of the gage.

76 STREAM MEASUREMENTS IN 1905, PART XI. 

GRAND RIVER AT HOT SULPHUR SPRINGS, COLO. 

This station was established July 27, 1904. It is located at the highway bridge one-eightli 

mile below Hot Sulphur Springs, Colo., in sec. 3, T. 1 N., R. 78 W., and is 5 miles above the 

mouth of Williams Fork River. 

The channel is straight for about 200 feet below the station. Above the station it is 

curved at almost a right angle. Both bn.nks are high and can not overflow. The bed of the 

stream is composed of bed rock, heavy gravel, and large bowlders on the right side, while on 

the left side it is a sloping gravel bar extending outward to the left abutment of the bridge. 

It is free from vegetation a,nd, except for the gravel bar, is permanent. There is but one channel at all stages broken by the two piers of the bridge. The current is swift and at low 

water passes under the bridge squarely. At high water the current in the greater part of 

the section passes under the bridge at an angle. The accuracy of measurements is affected 

by the boiling of the water at the piers and by the large bowlders in the channel beneath the 

bridge. During the spring and early summer of 190.1) the channel 100 feet below the station 

was somewhat ohstruct.ed by large bowlders which were blasted from a railroad cut on the 

right bank. This obstrudion backs the water np on the gage to a considerable extent and 

at extreme low stages causes dead water in a portion of the cross sections. 

Discharge measurements, except at Yery low stages, are made from the upstream side of 

the three-span bridge. The initial point for soundings is located over the inner face of the 

right abutment and is marked with a circle on the upstream hub rail. A stay line is.loeated 

30 feet above the bridge. 

The gage, which was read once each da.y during 1905 by ~·Irs. Carrie Wills, consists of a 

vertical staff, bolted vertically to the downstream end of the first pier from the right bank. 

The gage reads from 2 to 10.8 feet, the 2-foot mark resting on bed rock. The gage is referred 

to bench marks as follows: (1) A cross painted on the north pier above the gage rod; elevation, 16.48 feet above t"b.P zero· of the gage. (2) A eros<! eut in the top of a bench on the 

northwest face of a sandstone cliff on the east side of the road 50 feet south of the bridge; elevation, 25.49 feet above the zero of the gage. The elevation of the station above sea level 

is approximately 6,5.5() feet. 

A description of this station and gage-height and discharge data are contained in WaterSupply Paper, No. 133, United States Geological Survey, pages 135-137.

This station was established July 24, 1904. It is located at the mouth or upper end of 

Gore Canyon, about 3 miles southwest of Kremmling, Colo. 

The channel is straight for about 100 feet above and for 150 feet below the station. The 

right bank is the grade of the Denver, Northwestern and Pacific Railway; the left bank is 

abrupt and is covered with bowlders and bushes; neither bank overflows. The bed of the 

stream is composed of sand, silt, and bowlders and is very shifting, the change in channel 

being as great as 10 feet in places. The channel scours out during high-water stages and 

gradually fills up again as the water subsides. There is but one channel at all stages. The 

current is very sluggish at low water and medium to swift at high water. Gage heights 

have a range of about 15 feet during an ordinary season. Gage readings in the winter 

months are somewhat affected by ice in the channel. The shifting of the bed makes the 

development of a good rating curve a difficult matter. The ·statim~ is not entirely satisfactory, but it is the best location available below the mouth of Blue River. 

· Discharge measurements are made from a cable stretched across the river just below the 

gage and about 150 feet above the wagon bridge. The cable is approximately 280 feet 
GRAND RIVER. 79 

long and is tagged with tin tags marked every 5 feet from the top of the right bank, which 

is a high sandstone cliff, to the top of the left bank. The initial point for soundings is the 

face of the rock to which the cable is anchored on the right bank. 

Gage readings at this station were made twice each day during 1905 by J. C. Harper. 

The original equipment consisted of a wire gage attached to the cantilever arm of the 

frame to which the gage rod was spiked in a horizontal position. This gage was destroyed 

by high water in June, 1905, and after the water had subsided the old gage was placed on a 

new cantilever arm similar to the old one but about 3 feet higher, the gage datum remaining the same and the' wire was replaced by a standar<;l chain. The length of the chain is 

36.50 feet. Bench mark No. 1 is a cross cut in the east face of a large bowlder on the right 

bank about 20 feet south of the cable marked with black paint ''U.S. B.M.;" elevation, 

25.03 feet above the zero of the gage. The elevation above sea level is about 7,250 feet. 

Bench mark No.2 is a cross cut and painted block on top of a cone-shaped granite bowlder 

on the left bank of the river about 50 feet downstream from the gage. Elevation of bench 

mark above gage datum is 9.57 feet. This bench mark is submerged at high water. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pages 137-139.

GRAND RIVER AT GLEN,VOOD SPRINGS, COLO. 

This sf.ation is located in the mountains, midway between the Continental Divide and the 

Colorado-Utah boundary line, and just above the third large tributary of the Grand, which is 

<.;ailed Roaring Fork. 

A comparison of the miscellaneous discharge measurements made at the mouth of Roaring 

Fork, at Glenwood Springs, during 1903 and 1904, with the discharge of the Grand, at Glenwood ~prings, shows that the volume of water being discharged by the Roaring Fork augments the volume of water which passes the Glenwood station by 50 per cent. While there 

is a moderate amount of inigation of the first bottom lands from the tributaries above this 

point, relatively little of the run-off of the basin is used. 

The station wus established May 12, 1899, at the request of the Denver and Rio Grande 

Railroad Company. It was at first located at the railroad bridge, a quarter of a mile west of 

the depot and just above the mouth of Roaring Fork; but at the beginning of 1900 it was 

removed to a point near the electric-light works. The measuring section is located at the 

State Street Bridge, which crosses the r-iver at the main thoroughfare of Glenwood Springs, 

and is about 10 feet below the point at which all discharge measurements from 1900 to 1904, 

inclusive, were made. · 

The channel at the cable section is straight for a distance of several hundred feet each way. 

The left bank is the Denver and Rio Grande Railroad embankment and is well protected by 

a concrete and dry rubble retaining wall. The right bank is a low wall composed.of bowlders, 

without any binding material, and protects the grounds of the Hotel Colorado. At extremely 

high water these grounds have been flooded, but this is a rare occurrence. The bed·o1 the 

stream is-composed of bowlders and cobblestones and is permanent. A small amount of silt 

is deposited at low water, but it scours out in the spring and does not change the ctoss·section 

materially. There is but one channel at all stages. At high water the current is swift, often 

reaching a velocity as high as 20 feet per second; at low water the current. has a modPrate 

velocity. Gage heights runge from 2.5 to 12 feet. . · .. 

Discharge measurem~nts since May 16, 1905, have been made by means of a cable, car, 

and stay line 6o feet upstream, the cable being anchored to the piers of the State Street 

Bridge. Measurements from 1900 to 1904, inclusive, were made from the footway which 
82 STREAM MEASUREMENTS IN 1905, PART XI. 

erosses the stringers of the bridge below the roadway, about 10 feet above the present seetion. Plottings of old and new eross seetions show no material difference. 

Gage readings at this station are made by W. H. Riehardson, the manager of the Glenwood Electric Light and Power Company, morning and evening eaeh day during the entire 

year. The first gage was wire, but when the station was removed to the eleetric-light works 

a new gage rod was placed. This consisted of a light vertica~ staff, to the lower end ?f which 

was attaehed a wooden float, which rested on the surface of the water, standing in a well or 

box made-of 6-inch boards. The bottom of this well conneeted with a small wooden flume 

extending out into the river, which allowed the water in the well to assume the level of the 

river surfaee. In July. 1902, this gage being in bad repair was replaeed by an automatic 

water•register, the site being the same as that of the old float gage. The register never 

worked satisfactorily and was later replaced by another float gage, using the same well and 

intake flume. The present gage eonsists of a eopper float and eounterweight eonnected 

with a silk line passing over pulleys so arranged that a rise of 1 foot of the river registers but 

one-half foot on the rod. By this arrangement the large rise and fall of the river is readily 

aec~mmodated by a length of gage that would be impossihle with a direct-reading gage. 

The gage rod proper con8ists of a light pine rod, 1 by 1 inch by 5 feet, seeurely fastened in 

a vertical position inside a small house in which the apparatus is located and which sets on 

top of the vertical well. A pointer attached to a counterweight slides along the gage rod 

and registers the rise and fall of the river. This gage has given entire satisfaction. The 

original basis for the installation of this gage and the method of correction since that time is 

the relation of the depth of waterin the well to the gage reading. When the gage reads correctly the differenee between the depth of water in the well and the gage reading is 2.25 feet. 

The bench mark established June 27, 1904, is a cross cut in the top of the foundation capstone of the power house directly in front of the gage house, east of the power-house door, 

and is indicated by the letters '' B.M." cut in the vertical faee of the foundation stone on 

which the beneh mark is loeated. Elevation of bench mark above the datum of the gage is 

17.77 feet.

GRAND RIVER NEAR PALISADES, COLO. 

This station was established April 9, 1902. It is loeated at the steel highway bridge at 

the point where the river enters Grand Valley, 2 miles above Palisades, in T. 11 S., R. 98 W., 

and is above all irrigating ditches supplying water to Grand Valley, with the exeeption of 

one pumping plant, which takes about 20 seeond-feet from the river one-fourth mile above 

the station. 

The stream channel is straight for 600 feet both above and below the station. The right 

bank is high and rocky, is composed largely of bowlders, cobblestones, and gravel, and will 

not overflow. The left bank is somewhat lower and will overflow for a short distance, but 

only at extreme high water. It is composed primarily of bowlders covered with sand. 

Above the banks are narrow mesas merging into abrupt talus slopes capped by sandstone, 

which rise precipitously for several hundred feet. From station 70 to station 140 the bed 

of the stream is approximately level and is composed of solid sand~tone. Below the surface of the water on each ::;ide of this clean portion of the channel are large fragments of 

sandstone and large lava bowlders. During low water a deposit of silt forms to a depth of 

about 1 foot in the deeper portion of the ehannel and also fills in the large interstices of the 

rough banks. At high water .this deposit is scoured out. The depth of the water varies 

from 12 feet at low stages to 22 feet at extreme high stages. This unusual depth of water 

at the low stage is due to the retardation of flow caused by immense sandstone bowlders 

and detritus aeross the stream channel, about 1,500 feet below the station, at a point loeally 

called the Narrows. As a result the low-water current is sluggish and there are considerable 

areas of dead or backwater along each side. At high water the current is moderate at the 

sides, increasing very rapidly toward the eenter of the stream, where velocities of 20 feet per 

second have been observed. There is but one channel at all stages. Surface ice fo.t:IDS 

across the channel during winter. 

At the reeently constructed suspension bridge at Palisades the channel is straight, wide, 

and of uniform depth, the bed is of eobblestones, and the stream current is even. Conditions at the suspension bridge are far superior to those at the highway bridge for highwater measurements, while the reverse is true for low-water measurements. 

At low water diseharge measurements are made from the downstream side of the singlespan steel highway .bridge, which is 212 feet between masonry abutments. The initial 

point for soundings is the edge of. the capstone of the left masonry abutment. .At high 
GRAND RIVER. 85 

stages discharge measurements are made from the 320-foot suspension bridge at Palisades, 

the initial point for soundings being at the face of the left abutment. 

The gage, which was observed twice daily during 1905 by S.M. Purdy, was originally of 

wire and was located on the downstream side near the center of the highway bridge. On 

April5, 1904, the wire gage was replaced by a new chain gage. The zero of the ehain gage 

is identical with the zero of the wire gage. The scale on the inside of the chain-gage box 

reads from 11.6 to 22.5 feet. The length of the chain is 21.27 feet. The beneh mark is a 

point on the capstone on the downstream end of the approach abutment on right bank of 

river. It is marked with a circle cut about the point and the lett-ers "B. M. ;" elevation 

above the zero of the gage, 29.49 feet.

Fraser River rises among the peaks of the Front Range in southeastern Grand County, 

Colo., and flows in a general northwesterly direction to its point of junction with Grand 

River in the east-eentral part of Middle Park. The stream receives a number of small tributaries, among which are Elk, St. Louis, Crooked, and Pole creeks, all short mountain streams 

draining the eastern slopes of the Vasquez Mountains. 

The gaging station was established July 28, 1904. It is located on the main road between 

Coulter and Grand Lake, at the wagon bridge three-fourths mile southwest of Granby and 

about 4 miles above the mouth of the river, in sec. 9, T. 1 N., R. 76 W. In the 1904 Progress Report this station was called Fraser River, near Coulter, Colo. 

The channel is straight for about 100 feet above and curved for 100 feet below the station. 

The right bank is about 2 feet high, is covered with willows, and overflows at high stages. 

The left bank above the station is a high, abrupt mesa; below the station it is a 6-foot mesa 

for about-.50 feet, then a low, brush-covered flat, which is overflowed at high stages. The bed 

of the stream is composed of smooth cobblestones, and the cross section is fairly uniform, 

clean, and pem1anent. There is but one channel at all stages, broken by two crib piers, 

which cause boiling effects and back water at high stages. The current is swift at high and 

medium at low water. Gage heights have a range of about 2.5 feet during an ordmary season. lee conditions render winter gage readings impracticable. 

About 40 feet below the bridge a small temporary diversion dam is placed in the stream 

every year for the greater part of the low-water season to divert water into an irrigation 

ditch on the left bank. This weir backs the water up on the gage to a considerable depth 

and necessitates the construction of a separate rating curve for this period. 

Discharge measurements are made from the downstream side of the three-span bridge to 

which the gage is attached. The initial point for soundings is immediately over the inner 

face of the left abutment and is marked with a circle on the downstream hand rail. 

The gage, which was read twiee eaeh day during 1905 by J. N. Ostrander, a eivil engineer, 

who lives but a few hundred feet away, is a staff, spiked vertieally to the downstream inner 

edge of the first pier from the left bank. The gage reads from 2 feet to 10.8 feet, the 2-foot 

mark resting on the bed of the stream. The gage is referred to bench marks as follows: 
88 STREAM MEASUREMENTS IN 1905, PART XI. 

(1) A nail in the top of the white-pinl' stake driven into the left bank about 30 feet south of 

the left end of the bridge, proj~ting about 6 inches above the surface of the ground, and 

marked "U.S. G. S. B. M.;" elevation, 13.12 feet above the zero of the gage. (2) A cross 

cut on the top of the foundation stone at the southeast corner of the residence of the observer. 

The stone is marked "U. S. B. M." on the east face; elevation, 13.09 feet above the zero of 

the gage.

Williams Fork rises in the Williams River Mountains in southeastern Grand County, 

flows in a general northwesterly direetion, and unites with Grand River in the central part 

of Middle Park, Colorado. 

The gaging station was flStablished July 2.5, 1904. It is loeated at the wagon bridge on 

the ranch of F. A. Field, in T. 1 N., R. 79 W., about 9 miles west of Hot Sulphur Springs, 4 

miles above the mouth of the stream, and below all the tributaries. 

The channel is straight for about 100 feet above and below the station. 'l'he right bank 

is a low gravel bar, lined with willows, and at extreme high stages is overflowed for a distance of 75 feet from the second channel. 'l'he left bank is a level pasture land, about 4 

feet high, and is not liable to overflow. The bed of the stream is composed of small and 

medium-sized bowlders and is permanent. At low water' there is but one channel; at high 

water a second channel begins a.bout 300 feet above the bridge, on the right side of the 

strearn, passes about 100 feet from the right end of the bridge, and enters the main stream 

200 feet below. This ehannel is very rough and irregular and is almost entirely covered 

with gmss and sht·ubbery. 'l'he current is swift at high and medium at low stages. Gage 

heights have a range of about 1.8 feet in an ordinary season. During the winter months 

ice obstructs the channel to such an extent as to make gage readings impracticable. Highwater measurements arc affected by the back water and boiling caused by the middle pier 

of the bridge and by the roughness of bed of the second channel. 

Diseharge mea.."lurements are made from the downstream side of the 2-span wooden 

bridge to which the gage is attached. The initial point for soundings is a 60-penny nail 

. driven into the top of the left end of the downstream guard rail of the bridge, immediately 

over the inside face of the abutment. The second channel formed at high water is measured by wading at convenient points. 

The gage, which was read twice eaeh day duririg 1905 by F. A. Field, is a staff, graduated 

from 2 to 8 feet, fastened vertically to the downstream end of the middle crib pier, the 2-foot 

mark resting on the bed of the stream. The bench mark is a 60-penny nail driven into the

south face of a white-pine tree standing on the left bank of the river 30 feet north of the 

west end of the bridge; elevation, 6.03 feet above the zero of the gage. Ele-vation above 

sea level is about 7,600 feet. ' 

A description of this station, with gage-height and discharge data, is ~tained in WatbrSupply Paper No. 133, United States Geological Survey, pages 146-148.

Troublesome River rises among the peaks of the Continental Divide in the northern part 

of Grand County, Colo., and flows southward to its point of junction with Grand River in 

Middle Park. 

The gaging station was established July 22, 1904. It is located about 100 yards below 

the highway bridge at Troublesome, Colo., in see. 12, T. 1 N., R. 80 W. 

The channel is straight for about 50 feet above and 100 feet below the station. The right 

bank is about 3 feet high and is lined with a heavy growth of willows; the left bank is preeipitous, is about 4 feet high, and is bordered by a level meadow; neither bank overflows. 

The bed of the stream is composed of small cobblestones and gravel, and is clean, uniform, 

and permanent. There is but one channel, broken by the piers of the bridge, which form 

eddies and undercurrents in a portion of the cross section. The current is very swift at high 

and medium at low stages. Gage heights have a range of about 2.5 feet in an ordinary 

season. During the winter months the channel is so obstructed by ice as to make gage 

readings impractieable. 

Discharge measurements are ordinarily made by wading at convenient points near the gage 

rod. At extremely high stages they are made from the 2-span bridge about 100 yards · 

above the gage-rod. The initial point for soundings is the west face of the stake driven into 

the tol? of the left bank, to which the gage rod is fastened. 

The gage, which was read twice each day during 1905 by Mrs. Eva M. Becker, is an inclined 

staff, graduated from 0.8 foot to 5.8 feet, securely fastened to stakes driven into the left 

bank and bed of the stream. One vertical foot equals 1.525 feet on the slope. The gage is 

referred to bench marks as follows: (1) A 10-penny nail driven into the top of the stake on 

the left bank to which the gage is fastened; elevation, 5.83 feet above the zero of the gage.

(2) The center of a black cross painted on the bottom log near the southeast corner of Mrs. 

E. M. Becker's house, marked "U. S.+B. M.;" elevation, 16.08 feet above the zero of the 

gage.

Muddy River rises among the high peaks in the northwestern part of Grand County, 

Colo., and flows southeastward to the point where it unites with Grand River. 

The gaging station was established July 24, 1904. It is located at the highway bridge 

about one-eighth mile northwest of Kremmling, in sec. 7, T. 1 N., R. 80 W., about 2 miles 

above the mouth of the river. The station is below all tributaries of importance. 
94 STREAM MEASUREMENTS IN 1905, PART XI. 

The channel is curved for about 100 feet above and straight for 50 feet below the station. 

The right bank is about 8 feet high above and 10 feet high below the station, and is clean 

and almost perpendicular. The left bank below the bridge is 10 feet high, slopes at an angle 

of about 45 degrees, and is lined with willows; above the bridge it is irregular and about 8 

feet high. The stream at this point does not overflow except at extremely high stages, and 

then only for a short distance back from the left bank. The bed of the stream is composed 

of mud, with some sand and a few loose rocks washed from the riprap near the south abutment of the bridge, and is clean hut shifting. There is but one channel at all stages, broken 

hy the middle pier of the bridge, which is irregularly shaped and causes back water and 

undercurrents in a portion of the cross section, affecting the discharge measurements at 

high stages. The current is medium at high and very sluggish at low water. The shifting 

of the bed makes it very difficult to obtain a good rating curve. Gage heights have a range 

of about 6 feet during an ordinary season. In the winter months ice obstructs the channel 

to such an extent that gage readings are impracticable. 

At high-water stages discharge measurements are made from the downstream side of the 

two-span highway bridge to which the gage is attached. The initial point for soundings 

is a 10-penny nail driven into the downstream hand rail over the north face of the left abutment. The hand rail is marked from 0 to 58 feet with nails driven at 2-foot intervals. At 

ordinary and low-water stages measurements are made by waqing at convenient points 

below the station. 

The gage, which was read twice each day during 1905 by C. S. McGee, is a staff attached 

vertieally to the lower left eorner of the middle pier of the bridge. The gage reads from 2 

to 14 feet, the 2-foot mark resting on the bed of the stream. The gage is referred to beneh 

marks as follows: (1) A 60-penny spike driven horizontally into the west face of the left 

end of the downstream bridge stringer over the left abutment; elevation, 13.65 feet above 

the zero of the gage. (2) A 30-penny nail driven horizontally in the stringer at the east 

end of the north abutment of the bridge; elevation, 13.95 feet above the zero of the gage . 

.A. description of this station with gage height and diseharge data is eontained in Water··

Blue River rises among the peaks of the Continental Divide in the extreme southeastern 

part of Summit County, Colo., and flows in a general northwesterly direction until it joins 

Grand River above the point where the latter stream enters Gore Canyon. 

The gaging station was establishea July 21, 1904. It is located at the State highway 

bridge on the road between Kremmling and DiHon, Colo., 17 miles from the former and 26 

miles from the latter, in T. 2 S., R. 80 W., and is below all tributaries of any importance. 
BLUE R1VER DRAINAGE BASIN. 97 

The channel is straight for about 400 feet above and 200 feet below the station. The 

banks are lined with willows and are not liable to overflow. The bed of the stream is very 

rough, but is clean and stable. There is but one channel at all stages, broken by the center 

pier of the bridge. Several large bowlders in the ehannel near the gaging seetion eause a 

wave and boiling motion of the water at high stages and eddies and dead water during 

low stages. Gage heights have a range in an ordinary season of about 2.5 feet. During 

the winter months iee forms in the ehannel to sueh an extent as to make gage readings 

impraetieable. 

Diseharge measurements are made from the downstream side of the two-span iron bridge 

·to which the gage is attached. The initial point for soundings is a 4-penny nail driven 

into the downstream guard rail at the left end of the bridge immediately over the east face 

of the left abutment. It is marked zero. 

The gage at this station is read once each day by Mrs. Dolly Heatherly, who lives 1 mile 

south of the bridge. The original gage was a staff, graduated from 2 to 11 feet, fastened 

vertically to the west face of the middle masonry pier near the downstream end. On 

August 26, 1904, this gage was removed and was replaced by a regulation chain gage, the 

elevation of the datum of the two gages being the- same. In September, 1905, the wooden 

gage was reset in its original position and datum and is to be used during season of high water; 

at all other times the chain gage is to be used. The gage is referred to bench marks as 

follows: (1) A cross cut in the top of the second step from the top of the downstream wing 

of the left abutment, painted bhtck, and marked "U. S.+B. M."; elevation, 9.04 feet above 

the zero of the gage. (2) A 60-penny spike driven vertically into the west end of the 

block, to which the pulley of the gage is fastened; elevation, 11.69 feet above the zero of 

the gage. 

A description of this station, with gage height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pages 151-153.

EAGLE RIVER DRAINAGE BASIN. 

EAG.I .. E RIVER NEAR EAGLE, COLO. 

Eagle River, an important headwater tributary of Grand River, rises among the high 

peaks of the Continental Divide, in Eagle County, Colo., immediately opposite the headwaters of Arkansas River, flows a little north of west for about 20 miles, and then in a 

general westerly direction to its junction with the Grand. It is a very rapid stream throughout Its entire course, flowing alternately through canyons and narrow, terraced valleys. 

The drainage area is almost wholly in Eagle County. The upper third of the basin is 

entirely mountainous, the general elevation at the crest of the divide being 12,000 feet above 

sea level, with peaks over 14,000 feet in altitude. In this part of its course the river descends in falls and eascades, the average slope above the mouth of Roche Moutonnee Creek 

being 150 feet per mile. The rocks are about equally divided between n~etamorphic granites and sedimentary formations. The forest cover is excelient, soil is shallow, and erosion 

is small. The annual precipitation, which is mostly in the form of snow, varies from 20 to 

30 inches. This portion of the basin furnishes 90 per cent of the discharge of the stream. 

The lower two-thirds of the basin is also mountainous but is Jess accentuated, the elevations varying from 7,000 to 11,000 feet. The rocks are largely sedimentary, erosion is 

greater, and the forest eover is meager. The precipitation is approximately 20 inches. 

The principal tributaries of the Eagle are Gore, Roche Moutonnee, Gypsum, and Brush 

creeks. 

Below Wolcott a few small ditches div<>.r water for irrigation of the narrow first bench 

lands, and there is enough irrigation in Gypsum and Brush Creek valleys to divert the entire 

flow during the latter part of the season. 
EAGLE RIVER DRAINAGE BASIN. 99 

The gaging station was established March 12, 1905. It is located at Rule's private road 

bridge, in T. 5 S., R. 85 W., 2! miles below Eagle, Colo. The chief object of the station is 

the collection of power data. 

The channel is straight for 250 feet above and 150 feet below the station. The right bank 

is high, is composed of bowlders, cobblestones, and gravel, and does not overflow; the left 

bank, a long, narrow bottom bordered by abrupt mesa bluffs, overflows at high water to 

base of bluffs. Both ban],i:s are covered with scattered trees and brush. The bed of the 

stream is composed of cobblestones and bowlders and is permanent but very rough. There 

is but one channel at all stages. At low water there is an area of dead water at. the left abutment, due to a depression in the bed of the stream under the bridge, and the current is sluggish; at high water this area of dead water disappears. The center of the current is very 

swift during high water. Above and below the bridge the. velocity is much greater than at 

the bridge. The height of water ranges from 0.8 foot to 6 feet on the gage. Ice forms over 

the channel under the bridge during cold weather. · 

Diseharge measurements are made from the downstream side of the 66-foot single-span 

wooden bridge, which stands at right angles to the strea.::n current. The initial point for 

soundings is the face of the left abutment. 

A vertical staff gage, which was read twice each day during 1905 by Kenneth Rule, is 

spiked to the face of the left abutment of the bridge. The gage is graduated from zero to 10. 

feet. The bench mark is a point encireled by paint and marked '· B.M." on a large bowlder 

at the right of the bridge; elevation; 15.72 feet above the zero of the gage.

GUNNISON RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN. 

Gunnison River is formed in Gunnison County, Colo., by the union of East and Taylor 

rivers, two streams that have their origin among the snow-covered peaks and on the slopes 

of the Continental Divide in the northeastern part of the county and which descend through 

narrow mountain valleys and unite ahout 12 miles above Gunnison. From. the junction of 

these rivers the Gunnison flows west and southwest to the point where it Pnters Grand RivPr 

at Grand Junction, in the central part of Mesa County, Colo. 

The upper course of the river lies through a broad, mountainous valley, but near the 

mouth of Lake Fork the valley narrows and the river enters the Black Canyon of the Gunnison, through which it winds in a tortuous course for 56 miles between granite walls that rise, 

precipitously :l,OOO feet above the water's edge. A short distance below the mouth of 

North Fork, the largest tributary of the river, the canyon walls break abruptly, and the 

valley is broad and fertile. Below Delta the river enters another nar-row canyon, with walls 

averaging 800 feet in height, and this continues irregularly to Grand ;Junction, a few tracts 

of narrow bottom land lying between the channel and the canyon walls. 

As an aid to description the basin may be divided into an· upper, mountainous area and a 

lower, plateau area, the two being divided roughly by a north-south line d~awn through the 

town of Hotchkiss. 

The mountainous portion of the basin is the greater in area and varies in altitude from 

6,000 to 14,000 feet. The ~eologic formations include. large areas of igneous as well as sedimentary rocks, the soil cover is shallow, and large tracts are entirely barren. In the more 

inaccessible parts of the region the primeval forest still exists, but at many places, especially 

in the neighborhood of the mining camps, the timber has all been cut off. The prevailing 

forests are spruce, aspen, cedar, and characteristic mountain undergrowth. All the arable 

land in the high mountain valleys is devoted to forage crops, and a number of small ditches 

divert water for their irrigation. Power development of considerable magnitude is feasible 

in this part of the basin. 

The plateau region embraces the Uncompahgre Plateau along the southwestern border of 

the basin, the Vernal and Inclinado mesas in the central part, and the Grand l\fesa in the 

northern part. These plateaus have an extreme elevation of 10,000 feet above sea level and 

break down in a series of broad steps to the valleys, with parallel drainage lines cutting 

deeply at right angles through these steps. The topography is the product of erosion acting 

on: sedimentary formations. The soil of the lower valleys is chiefly adobe, and the higher 
GUNNISON RIVER DRAINAGE BASIN. 101 

mesas have large content of gravel and sand. Groves of quaking aspen, interspersed with 

large, open grazing plots, cover broad areas of this plateau region. Forests of pine and 

aspen occur on the top of the Grand Mesa, with pinon pines and cedars along the foothills. 

In the vrJleys chico and sagebrush form the controlling vegetation, except along the streams, 

which are bordered to someextent by cottonwood, willow, and undergrowth. 

The chief tributaries of the Gunnison are Ohio, Tomichi, Lake Fork, and Cimarron creeks 

and Smith, North Fork, and Vncompahgre rivers, the North Fork being the largest . 

.North Fork River rises in the Huntsman Hills, 20 miles south of Glenwood Springs, flows 

in a general soutb and southwesto:lrly course, and unites with the Gunnison about 8 miles 

west of Hotchkiss. The drainage area is highly mountainous, except for a small portion 

which lies below Paonia, extreme points reaching an altitude of 13,000 feet. The mesa 

lands at the lower end of the valley stand 5,[1()0 feet above sea level. The higher peaks are 

formed of granitic ro(~ks, hut lower down Cretaceous formations occupy at least SO per cent 

of the area of the basin. The mountains are forested and the mesa lands are covered with 

sagebrush. All the tillable lands of the North Fork and its tributaries have been brought 

under cultivation, and irrigation is practiced to such an extent that the entire flow is needed 

for existing systems. 

Uncompahgre River, the principal tributary of the Gunnison from the south, rises among 

the snowy peaks of the highly serrated Uncompahgre Mountains and flows a little west of 

north to its junc.tion with the Gunnison at Delta. The basin embraces a mountainous, 

plateau, and valley area of 1,130 square miles, oblong in shape, the width increasing slightly 

at the lower end. The mountain area occupie'l but a small part of the basin, but contributes 

the perennial waters of the stream. The plateau area is greatest in extent and borders the 

valley on both sides, the larger :uncompahgre Plateau lying to the southwest. Escarpments are conspi~uous features of this plateau. The relief features are terraced mesas 

flanked by shale buttes and ridges, trenched by deep, narrow canyons. Pncompahgre VallPy proper begins at a point near Eldredge Siding, on the Denver and Rio Grande Railroad. 

The other tributaries of the Gunnison need not here be described. Ohio, Tomichi, Lake 

Fork, and Cimarron ereeks are perennial streams, but almost their entire volume is diverted 

for irrigation during the growing sea'!on, so that very little of their water reaches the Gunnison except at times of heavy storms or during spring floods. 

Precipitation records for the Gunnison basin are meager. Those which exist show a 

range from 9 inches in the plateau region to about 25 inches in the mountains. 

The natural flow of the Uncompahgre and North Fork rivers is diverted for irrigation 

along their respective valleys, ancl the Gunnison tunnel will divert water from the mountainous area and transmit it to the Uncompahgre Valley, which has been an irrigated district 

since the early eighties. 

EAST RIVER AT ALMONT, COLO. 

East River rises in the Elk Mountains in the northern par~ of Gunnison County, Colo., 

flows in a general southerly direction, and unites with Taylor River to form the GunPison. 

The gaging station was established April 17, 1905. It is located at the county highway 

bridge at Almont, 100 feet above Taylor River, in T. 51 N., R. 85 W. The object of the 

station is the determination of the amount of flood waters available for storage in connection with the Uncompahgre V nlley project and the collection of power data. 

The channel section measures 75 feet between the bridge abutments and is straight for 

100 feet both above and below the station. The banks are low and are liable to overflow. 

a.t extreme high water. The bed of the stream is composed of bowlders and cobblestones 

and is Yery rough but generally·permanent. There are two channels at all stages, divided 

hy the center pier of the bridge, and the current IS swift. Gage heights range from 0.7 

foot to S feet. 

Discharge measurements are made from the downstream side of the two-span wooden 

bridge. The initial point for so'undings is the face of the left abutment and is indicated 

by a brass-headed tack in the hand rail, marked with a circle. 
102 STREAM MEASUREMENTS IN 1905, P .ART XI. 

The gage, whieh was read during 1905 hy' Vernon Davis, is a vertical staff graduated 

from zero to 7 feet. spiked to the right end of the pier on the downstream side of the bridge. 

The bench mark is a point on a large stump in Cottage Grove on the right bank of the river, 

about 25 feet from the bridge, encircled hy black paint and marked "B. l\f. ;" elevation,

: ·I·········~ I· ... '~: ·-1~ TAYLOR RIVER NEAR ALMONT, COLO. 

Taylor River rises in northeastern Gunnison County, Colo., among the high peaks of the 

Continental Divide, flows in a general southwesterly direction, and unites with East River 

to form the Gunnison. 

The gaging station was established April17, 1905. It is located at George Clark's private 

road bridge, 14 miles above Almont, Colo., in T. 15 S., R. 83 W. The object of the station 
104 STREAM MEASUREMEN'l'S IN 1905, PAR-T XI. 

is the determination of the amount of flood water available for storage in conLection with 

the Uncompahgre Valley project, and the collection of power data. 

The channel is straight for several hundred feet both above and below the station. The 

banks are both low, composed of bowlders and earth, are partly lined with willows, and 

are not liable to overflow. The stream bed is made up of large bowlders and cobblestones, 

and is very rough but permanent. The fall is large, the slope being equal to 0.016, or about 

80 feet per mile. The crib piers of the bridge divide the channel into three parts. The 

velocity is rapid at all stages. Ice conditions interfere with measurements during the winter 

months. Accurate measurements are exceedingly hard to obtain on account of the roughness of the channel. 

Discharge measurements are made from the downstream side of a pole bridge, which is 

75 feet between abutments and is supported by two crib piers. The gage, which was read during 1905 by George Clark, is a vertical staff, graduated from zero to 7 feet, spiked to the left side 

of the left pier. The bench mark i~ a point, encircled with white paint and marked" B. M.," 

on top of a granite bowlder on the left bank just below the bridge; elevation above the zero 

of the gage, 4.34 feet.

GUNNISON RIVER NEAR CIMARRON. COLO. 

This station was established September 18, 1903. It is located at the Denver and Rio 

Grande Railroad bridge, 1! miles from Cimarron, Colo., 1,000 feet above the mouth of Cimarron River, in T. 19 S., R. 91 W. The purpose of the station was the collection of hydrographic data relative to the Uncompahgre Valley project, which comtemplates the diversion 

of 1,300 cubic feet of water per second from Gunnison River about 12 miles below. The 

station was discontinued December 16, 1905, having been replaced by the station established 

at the east portal of Gunnison tunnel in April, 1905. 

The channel is straight for 1,000 feet above and 300 feet below the station. The left bank 

is a granite cliff which rises vertically from the water. The right bank is a mountain slope 

of about 45°. The bed of the stream, which is permanent, is composed of granite bowlders along the sides with an even deposit of sinall cobblestones in the center. There is 

but one channel at all stages. At the cable section the left bank is an offset in the stream 

channel filled with a deposit of mud. The velocity is swift at low stages and very rapid 

during high water. Gage heights range from 3 to 12 feet. 

Discharge measurements are made by means of a cable, car, stay, and tag lines. The 

initial point for soundings is at the face of the left cliff, 20 feet from the eye bolt to which 

cable is fastened, and is marked zero on the tag line. 

A standard chain gage, which was road twice daily during 1905 by G. C. Gates, is installed 

on the upstream side of the Denver and Rio Grande Railroad bridge near the west €.nd, about 

75 feet downstream from the cable. The gage scale reads from zero to 10 feet, with two 

markers, giving a range of 20 feet in gage heights. The length of chain from end of weight 

to center of first marker is 56.06 feet. The bench mark is the top of the southeast corner 

capstone of the east masonry abutment of the Denver and Rio Grande Railroad bridge, a line 

being eut across the eorner of the eapstone to indieate the beneh mark; elevation, 56.52 

feet above the zero of the gage.

GUNNISON RIVER AT EAST PORTAL OF GUNNISON TUNNEL, COLORADO. 

This station was established April 1, 1905, and replaces the Cimarron station, 12 miles 

above. It is located about 100 yards above the portal of the tunnel and is in T. 49 N., 

R. 7W., 21 miles by wagon road from Montrose. The object of the station is to detennine the 

volume of flow of the river at this point, as 1,300 second-feet will be diverted by the Q-unnison 

tunnel when it is completed. 
GUNNISON RIVER DRAINAGE BASIN. 109 

The channe1 is straight for 500 feet above and 300 feet below the station. " The banks are 

steep, rocky mountain sides, and do not overflow. The bed of the :>tream is composed primarily of -solid ledges of schists with a shifting deposit of gravel and sand which reaches a 

depth of 3 to 4 feet at low water. There is but one channel at all stages. The current is 

sluggish at low water; but becomes swift during high water. page heights range from 5 to 

14 feet. 

Discharge measurements are made by mea,ns of a cabls, ~tar, and tag line. The initial 

point for soundings is the left bank 'at high-water mark and is indicated by zero on tag line. 

Tlu3 gageJ which is read twice daily by H. L. Da~iels, is a ~ertical staff, graduated from 

zero to 15 feet, bolted to a vertical eliff on the right bank oft e river 50 feet upstream from 

the cable. The bench mark is a United States Geological Sur ey standard aluminum tablet 

set in a rock ledge 50 feet south of the mouth of Gunnison tm nel; elevation of bench mark 

above the zero of the gage, 29.11 feet.

This station was established April30, 1903, It is located at the wooden highway bridge 

on the road between Delta and Cory, Colo., about 6 miles east of Delta. 

The channel is over 200 feet wide and is straight for 300 feet above and 500 feet below the 

station. The right bank is abrupt, high, and wooded, and does not overflow; the left bank 

is. a gradual slope of cobblestones, gravel, and sand to the annual flood plain; is partly covered wit~ trees and underbrush, and overflows at extreme high water. The bed of the 

stream is composed of bowlders and cobblestones and is permanent. There is but one 

channel at all stages. The current is swift at high water. Gage heights range from 5 to 13 

feet. 

Discharge measurements are made from the downstream side of the two-span bridge. The 

initial point for soundings is a brass tack in the hand rail at the center of the left pier, 

downstream side of bridge. 

A standard chain gage, which was read twice daily during 1905 by John Shea, is located 

on the downstream side of the bridge 90 feet from the right bank. The gage scale reads 

from zero to 10 feet, with two markers, allowing for a range of 20 feet in gage heights, the 

second marker being used above 10 feet. The length of the chain from the end of the 

weight to the center of the second marker is 14.12 feet. The bench mark is the top edge of 

the iron rim of the northwest cylinder pier, downstream side of bridge, marked with white 

paint at the point of B: M.; elevation above the datum of the gage, 17.59 feet.

GUNNISON RIVER AT WHITEWATER, COLO. 

This station was regularly established April 10~ 1902, incomplete series of gage heights 

having been obtained during 1895, 1897, and 1901. It is located at the steel wagon bridge 

constructed by the State of Colorado at a point about one-half mile above the railroad 

station at Whitewater, on the Denver and Rio Grand-e Railroad. It was intended that this 

station should replace that formerly maintaine-d on the Gunnison at Grand Junction, which 

was abandoned on account of conditions that rendered accurate gagings impossible. 

The channel is straight for 1,000 feet above and 500 feet below the station. The cross 

section at the bridge is 282 feet wide, is uniform in area, and is clean. The right bank is of 

alluvial material, with abrupt slopes about 14feet high; the left bank is of the same material, 
GUNNISON RIVER DRAINAGE BASIN. 113 

but slopes more gently and overflows at extreme high water.. The bed of the stream is 

composed of cobblestones, coarse gravel, and sand, and is fairly permanent. At the center 

of the cross section the current is broken by cylindrical piers and old sheet piling, and a 

small area adjacent to these fills in with silt at low water but scours out during high water. 

There is but one channel at all stages. The current is moderate at low water but swift at 

high. Gage heights range from 3.5 to 14 feet. 

Discharge measurements are made from the downstream side of the two-span steel bridge. 

A stay line is used at high water. The initial point for soundings is the edge of the capstone 

of the left masonry abutment on the downstream side of the bridge . 

. · The gage, which was read twice daily during 1905 by James Page, was originally of wire, 

and was located on the downstream side of the right span. On AprilS, 1904, the old gage 

was replaced by a new chain gage with the same datum. The gage scale is graduated from 

zero to 10 feet, with two markers, giving a range of 20 feet in gage heights. The length of 

the chain from the end of the weight to the center of the first marker is 21.59 feet. The 

second marker is 11.59 feet from end of weight and is used when gage heights are above 10 

feet. The bench mark, established July 3, 1904, is a standard United States Geological 

Survey iron bench-mark post located about 40 feet southeast of the east end of the bridge; 

it is stamped 4,653.6 feet above sea level; the elevation of the bench mark above the datum 

of gage is 6.83 feet. 

Information in regard to this station is contained in the following publications of the 

United States Geological Survey (Bull=Bulletin; WS=Water-Supply Paper):

118 STREAM MEASUREMENTS IN 1905, PART XI. 

CIMARRON CREEK AT CIMARRON. COLO. 

Cimarron Creek rises in the extreme. southwestern part of Gunnison County and flows 

northward to its point of junction. with Gunnison River. The drainage ~trea is entirely 

mountainous. During the ~ummer and fall short, heavy rainstorms occur frequently, and 

the rapid ru-n-off induced by the steep slopes of the basin causes sudden fluctuations in gage 

heights. 

The gaging station was established April28, 1903. It is located at Smith's private bridge, 

1,000 feet south of the Denver and Rio Grande Railroad station at Cimarron, in T. 48 N., 

B. 6 W., and about 1 mile abovethe mouth of Cimarron Creek. 

The channel is straight for 100 feet above and 250 feet below the bridge. Both banks are 

low, rocky, and partly wooded and have not been known to overflow during the past ten 

years. The bed of the stream is composed of bowlders and cobblestones and is very rough, 

but is stable. The gradient is steep, though somewhat uneven. At low water there is but 

one channel. At high water there are two chamiels divided by the ·central pier of the bridge. 

The current is always rapid. Gage heights range from 1.5 to 4 feet. Accurate measurements are difficult to secure on account of the roughness of the section and the swift and 

irregular velocities. 

Discharge measureinents are made from the downstream side of the footbridge, which is 

supported -by two log abutments and one log crib pier in the center of the stream. The 

initial point for soundings is the left abutment on the downstream side and is marked zero 

on the bridge. Th~ bridge was washed away in June, 19051 but was replaced shortly afterwards at a greater elevation. 

The gage, which was read during 1905 by J. L. Linscott, is a vertical staff graduated from 

zero to 6 feet, spiked to the face of the left abutment of the bridge on the downstream side. 

The bench mark consists of two nails driven into the root of a cottonwood tree 50 feet west 

of gage; elevation above the _zero of the gage, 8.24 feet. This station ·was discontinued 

December 31, 1905.

the United States Geologica! Survey:

UNCOMPAHGRE RIVER NEAR COLONA, COLO. 

This station was established April 9, 1904. It is located at the private road bridge of 

J. M. Duckett, in T. 47 N., R. 8 W., one-half mile above Eldredge siding on the Denver 

and Rio Grande Railroad nnd 3 miles above Colona, Colo. It is best reached by drivirg 

from Montrose. The station re;_Jlaces one that was established August 10, :!.903, at Kettle ·s 

bridge, 1 mile south of Colona, to take the place of the original station, which was locat£d 

one-half mile northea.."lt of Colona. Both of these stations were abandoned because of 

unsatisfactory conditions. 

The channel is straight for abcnt 300 feet above and below the station. The banks are 

about 4 feet high, are rocky and partly wooded, and neither is subject to _overflow. The 

bed of the stream is composed of large and small cobblestones, and a loose deposit of silt 

shifts along each side. There is but one channel at all stages and the current is swift. 

Gage heights range from 0.5 foot to 4 feet. A<;curate measurements are difficult to secure 

on account of the rough bed and steep gradient of the channel. 

Discharge measurements are made from the downstream side of the 46.2-foot single-span 

bridge to which the gage is attached. The initial point for soundings is the downstream 

edge of the left abutment. 

The gage, whieh was read during 1905 by Miss Clara Duckett, is an 8-foot board graduated 

from zero to 7 feet. It was spiked vertically to the upstream side of the left abutment. 

The high water of June, 1905, caused the pier to sink 0.18 foot during July, and on August 

14, 1905, the gage was moved to the downstream side of the left pier and set at the original 

datum. The bench mark is the upper edge of a large screw set about 3 feet above the 

ground in an 8-inch willow tree 75 feet south and upstream from the right end of the bridge; 

elevation, 9.97 feet above the zero of the gage.

UNCOMPAHGRE RlVER AT MONTROSE, COLO. 

This station was established April 22, 1903. It is located at the iron highway bridge 

west of Mo~trose and one-fourth mile west of the Denver and Rio Grande Railroad near· 

Haskell Park. 

The channel is straight for 100 feet above and 300 feet below the bridge. The right bank 

is of earth; the left bank is of earth below the bridge, but above the bridge is the steep 

slope of a shale bluff. Both banks are liable to overflow at extreme high water. The bed 

of the stream is com:Rosed of cobblestones and gravel and is quite rough. There is but one 

channel at all stages, broken during high water by the left pier of the bridge. The higher 

portion of the left side of the channel is covered with undergrowth which obstructs the flow 

during high stages. The current ts rapid at all times. Gage heights range from 2 to 6 feet. 

Discharge measurements are made from either side of the bridge. The initial point for 

soundings is at the inner edge of the lower cylinder bridge pier at the right bank. 

The gage, which was read twice daily during 1905 by Herbert Reeves, is a vertical staff, 

. graduated from zero to 8 feet, spiked to a wing dam 20 feet above the bridge. The zero of 

this gage, which was established April15, 1904, is ] .45 feet.higher than that of the· original 

gage which it replaced. The bench mark consists of two nails driven into a blaze on the 

root of a cottonwood tree 50 feet to the right of the gage; elevation, 8.61 feet above the 

zero of the gage.

GUNNISON RIVER DRAINAGE BASIN. 125 

UNCOMPAHG:RE RIVER AT DELTA, COLO. 

This station was established April29, 1903. It was originally located at a highway bridge 

one-fourth mile above the Denver anq Rio Grande Railroad bridge, but on November 17, 

1903, the station was removed to thel Denver and Rio Grande Railroad bridge, one-fourth 

mile northwest of the Denver and Rio prande Railroad station, in order that the measured 

discharge of the river might include tl)e mill-ditch waste. Excluding the discharge of seasonal high water in May or June ar>d ab occasional rise from local storms, the water passing 

this station is entirely seepage water from irrigation above. 

The channel at the gage rod anc! the bridge below is a long gentle curve. The right bank 

is of earth, is high and clean, and is not subject to overflow. The left bank is also of earth 

and is clean; but it is low and may overflow during extreme high water. The bed of the 

stream is composed of earth and fragments of rock and is fairly permanent. There is but 

one channel at all stages. The current is sluggish at low and swift at high water. Gage 

heights range from 0.6 foot to 4 feet. 

Discharge measurements were originally made from the highway bridge, to which the 

first gage was attached, or by wading near the gage. From November 17, 1903, to May 2, 

1904, measurements were made from the Denver and .Rio Grande Railroad bridge. After 

the latter date measurements were made from the single-span road bridge 100 feet below the 

new gage. The initial poirit for soundings is the face of the left abutment at the downstream side of the road bridge and is marked by a brass-headed nail in the hand rail. At 

low-water measurements are made by wading near the bridge. · 

Gage readings at this station are made by Michael O'Rourke. The first gage at the railroad bridge was a vertical rod"nailed to a 12-inch pile on the downstream side of the bridge. 

It read froml foot to 6 feet. Readings were taken from this gage untilApril21, 1904, when a 

new gage was installed on the right bank 45 feet east of the center of the Denver and Rio 

Grande Railroad track at the south approach to the bridge. There is no definite and constant 

relation between the new and old rods as the cross sections are not identical. The new gage 

is an inclined rod,graduatedup to6feet. The bottom of the rod rests on the rivet· bottom and 

is held in place by six 2- by 4-inch timbers driven firmly into the bank. The bench m~rk for 

the vertical gage was a cross on the top of the lower chord of the bridge over the gage rod; 

its elevation was 8.75 feet above the zero of the gage. The bench mark for the inclined gage 

is a point marked with black paint and the letters ''B. M.," on the surface of the northeast 

corner of the stone abutment where the south end of the steel bridge rests, on the downstream side; e~evation, 7.36 feet above the zero of the gage.

COLORADO RIVER DRAINAGE BASIN BETWEEN JUNCTION OF 

GRAND AND GREEN RIVERS AND YUMA. 

COLORADO RIVER. 

DESCRIPTION OF RIVER. 

From the junction of Grand and Green rivers the Colorado flo~s southwestward, passes 

across the northwestern corner of Arizona, then turns to the south and for the rymainder of 

its course forms a part of the southeastern boundary of Nevada and California and the.western boundary of Arizona. It empties into the Gulf of California about 60 miles below Yuma, 

Ariz. The canyons through which it flows are world famed and need not here be described. 

The Colorado has been called the Nile of America, and like the Nih it is subject to an 

annual summer rise which comes at the time when it is most needed for irrigation. It is of 

interest to compare the Colorado with the Nile and Susquehanna rivers. The Nile being 

similar in type, the Susquehanna being contrasted and showing the difference in flow between 

arid and humid regions. In this comparison a normal year based upon records of the past 

ten years for the Colorado and Susquehanna rivers and such data as could be found in regard 

to the Nile ha.S been used. The Colorado has been taken as the standard of comparison 
128 STREAM MEASUREMENTS IN 1905, PART XI. 

The Nile has 5.7 times the drainage area and the Susquehanna about one-eighth the area. 

The rainfall in the Nile basin is 3.8 times greater; that in the Susquehanna basin is 4.5 

times greater. The run-off per square mile from the Nile basin is 1.9 times greater; that 

from the Susquehanna basin is 37 times greater. The ratio of rm:~-off to rainfall in the Nile 

basin is 2 times smaller; that of the Susquehanna basin is 8.2 tim~s greater. 

The discharge of the Nile is 10.8 times greater; that of the Susquehanna is 4.5 times 

greater. 

The maximum flow of the Colorado is from 70,000 to 110,000 second-feet and occurs in 

May, June, or July; for the Nile it is about 353,000 second-feet and occurs about the first of 

September; for the Susquehanna it is from 200,000 to 400,000 second-feet and occurs during March, April, and May. 

The minimum flow of the Colorado is from 2,500 to 3,000 second-feet and occurs during 

January and February; that of the Nile is about 14,500 second-feet and occurs about the 

end of May; for the Susquehanna it is from 2,500 to 5,000 second-feet and occurs in September and October. 

The mean flow of the Colorado is. about 10,700 second-feet; for the Nile it is about 115,800 

second-feet; for the Susquehanna it is about 43,000 second-feet. 

The water of the Colorado carries an immense amount of sediment, reaching as high as 

2,000 parts of sediment to 100,000 parts of water. Prof. R. H. Forbes, in Bulletin No. 44, 

University of Arizona Agricultural Experiment Station, says: 

On the basis of the profile constructed from available data for the vo!ume of flow of the Colorado. and 

of the year's s:It determinations made in the laboratory, it is estimated conservatively that the river 

during 1900 brought down about 61,000,000 tons of sedimentary material, which, condensed to the form 

of solid rock, is enough to cover 26.4 square mlles 1 foot deep, or to make about 164 square miles of recently 

settled, submerged mud 1 foot deep, reckoning the whole amount of mud for the year to average 6.2 

times the bulk of the solid sediment. 

A comparatively small amount of land is irrigated by the waters of the Colorado, owing 

to the fact that the stream and its tributaries are situated so far below the level of the irrigable lands as to render their diversion extremely difficult or impracticable. There are two 

pumping plants that lift water for irrigation at Yuma and several at other points on the 

river above Yuma. The Imperial canal diverts water from _the river at a point about 10 

miles by river below Yuma. 

The principal tributaries of the Colorado below the Grand and Green are the San Juan, 

Little Colorado, Bill Williams Fork, and Gila rivers, which enter from the east, and the Virgin River, which enters from the west. With the exception of the Virgin and Bill Williams 

Fork rivers, these streams and their various tributaries are described in other parts of this 

report. 

COLORADO RIVER AT HARDYVILLE, ARIZ. 

Thisstation was established May 11, 1005. It is maintained in cooperation with the 

State of California, and is located one-fourth mile above the deserted town of Hardyville 

and 7 miles above Fort Mohave, Ariz. 

The right bank is composed of cemented gravel, is high, and is not subject to overflow. 

The left bank is made up of ailuvial material, easily eroded, is low and wooded, and is liable 

to overflow at flood stages. The bed is composed of cemented gravel and changes gradually 

as the river falls from flood stage to low water, a bar forming in that portion of the section 

nearest the right bank and altering the section materially. There is but one channel at all 

stages. The flow ranges from 3,000 to 100,000 second-feet, with velocities of from 2 to 8 

feet per second and a variation of probably 12 feet in gage heights. 

Discharge measurements are wade from a car and cable located 250 feet above the pumping plant of the Rattan mi1l. The initial point for soundings is the end of the turn-buckle 

farthest from the river on the Nevada side. 

The gage, which was read once each day during 1905 by Marion Herrick, is located 275 

feet below the cable on the left bank. The gage is in two sections: The low~r section is an 

inclined rod fastened to posts buried in the bank; the upper section is a timber set vertically 
COLORADO RIVER. 129 

:n the bank. The bench mark is the top of a 3-inch iron pipe buried in the gravel bank 1~ feet from the river and 40 feet below the _gage rod. Its elevation is 20.54 feet above the zero 

of the gage and 507.18 feet above sea level.

COLORADO RIVER DRAIN AG ~ BASIN. 

SAN JUAN RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN. I 

San Juan River rises among the snow masses that crown the high peaks of the San J~an Mountains in southwestern Colorado, flows southwestward into.New Mexico, then sw~ngs 

to the west and northwest, passing from San Juan County, N. Mex., across the extrfme 

southwestern corner of Colorado into San Juan C,ounty, Utah, in the southwestern pa~ of 

which it unites with the Colorado. . I 

For the first 75 miles of its course the San Juan is a typical mountain stream, but at Qanyon Largo, N.Mex., where it turns westward, its character changes, and it occupies a brQadwinding, sandy channel in an arid valley, bordered on each side by terraced mesas. Bdlow 

the mouth of Mancos River the valley narrows and the river bottom is bounded by ab~pt 

bluffs, broken and cut by dry water channels, and merging farther on into the walls pf a 

deep, narrow, box canyon in which the river flows to its end. I 

The drainage area includes portions of four States and Territories. Its topography ra.ges 

in type from mountainous at the headwaters in Colorado to the types exemplified inj the 

valleys, pl"S.teaus, and eroded mesas of Utah, New Mexico, and Arizona. Large are~s of 

eruptive rocks occur in the highest portions of the basin, but the predominating format~ons 

are of sedimentary origin. The headwater streams are protected by fine forests of spi'uce 

and yellow pine and, at lower elevations, large areas of aspen. The lower basin is prtctically barren except for an extensive growth of· sagebrush, scattered cedars, pinons, jnd 

range grass,es. , 

The principal tributaries of the San Juan are Navajo, Piedra, Pine, Florida, Animas, land 

La Plata rivers, the Animas being the most important. I 

· Animas River has its source in the region~ above Silverton, draining portio~ of the 1dle 

and La Plata mountains, the former being the most rugged of the Rocky Mountain r ges. 

The river flows southward to the Colorado-New Mexico line and thence southwestwa to 

the point where it joins the San Juan at Farmington, N. Mex. The upper portion of the b sin, 

above Durango, is very mountainous and furnishes the greater part of the nm-off. his 

region is generally well timbered with pine, spruce, and aspen, but large areas consift of 

naked granite peaks. Immediately above and below Durango the valley broadens a~d is 

bordered by mesas and bluffs cut by narrow canyons and covered with sagebrush and fcattered pines and pinons; along the stream channels cottonwoods predomihate. The pcks 

of this region are chiefly of sedimentary origin. The soils of the lower valleys consift of 

sandy loam and are very fertile. ! 

La Plata River rises in the granite masses known as La Plata Mountains, about 25 !files 

northwest of Durango, Colo., and flows southward to its point of function with the San ~l,lan. 

Its drainage basin is a narrow strip parallel to and adjoining the Animas basin. The tifPper 

pertion of the basin is a well-watered and forest-clad mountain region which merges squthward into an arid mesa, plateau, and canyon country. La Plata Valley proper is a nat'row, 

shallow depression from Hesperus down, bounded on both sides by high, broken table- nds 

and deeply eroded mountains. The lower mountain slopes are covered with pinon, rub 

oak, and cedar; the lower valleys support heavy growths of sagebrush and chico; thetper 

mountain slopes were at one tfme heavily timbered with spruce and yellow and white ine, 

but these forests have been largely removed by lumbermen. 1 

The other tributaries of the San Juan need not here be described. Those mentiont are 

perennial streams but much of their water is diverted for irrigation and never reach the 

main river. In addition to the perennial streams are many intermittent creeks throu out 

New Mexico which col!tribute large volumes of water during heavy storms. · , ~ 

Much land is now under cultivation along the valleys of the San Juan, Animas; JPine, 

Florida, and La Plata rivers and the smaller tributaries in Colorado. Numerous rmall 

lakes high up in the mountains tend to equalize the flow of some of the tributariesL and 

. many large and small storage-reservoir sites are available which wi,ll i~ time be develrped.

One large power plant has been constructed in this basin and others are contemplated. The 

largest deposits of lignite and bituminous and coking coal to be found in the West are in this 

drainage area. 

SAN JUAN RIVER NEAR FARMINGTON, N. MEX. 

This station was established Ju.ne 18, 1904. It is located near the Methodist Indian 

school about 3 miles south of Farmington, N.Mex., and about 2 miles below the mouth of 

Animas River. 

The channel is straight for about 900 feet above and below the station. The right bank 

is a high sandstone cliff and can not overflow. The left bank at low water is a gravel bar 

extending out to 325 feet from the initial point for soundings, when it rises to a height of 

6 feet; it prob~bly never overflows beyond this point. The bed of the stream is composed of 

eobblestones, shale, and a few large, scattered bowlders. It is clean and permanent except 

on the left side where sand rests on the shale. There is but one channel at all stages. The 

current is swift at high and medium at low water. Gage heights range from 3 to 12 feet. 

Discharge measurements were made from the susp~nsion footbridge, which was carried 

~way by the high water of 1905. Since then discharge measurements have been impracticable as there is no other bridge on the river. 

The gage, which was read during 1905 by Elmer King, is a standard chain gage and is 

attached to a framework extending from the top of a sandstone eliff, about 15 feet above 

low water, on the right bank of the river, about 300 yards above the bridge. The gage 

scale is placed horizontally on the top of the cliff and is graduated from zero to 20 feet. 

The length of the wire from the end of the weight to the marker, which is a knot tied in 

the wire near the ring, is 20.79 feet. On May 23,1905, a high-water gage, consisting of an 

inclined staff graduated to read from 8.6 to 16.4 feet, was set in the right bank about 

150 feet below the wire gage. The bench mark is a cross, painted black and marked 

"U. S. G. S. B. M.," on the top of the sandstone cliff about 50 feet east of the gage; 

elevation above the datum of the wire gage, 12.79 feet. The top of the gage rod (above 

the brace) is 0.82 foot above the bench mark. The elevation of the bench mark above the 

datum of the new gage is 12.94 feet, and hence the datum of the new gage is 0.15 foot above 

the datum of the old gage. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pp. 180-183. 

A measurement made oy M. C. Hinderlider May 23, 1905, gave the following ret~ults: 

Width, 302 feet; area, 1,764 square miles; mean velocity, 9.73 feet per second; gage height, 

10.55 feet; discharge, 17,170 second-feet.

ANIMAS RIVER AT DURANGO. COLO. 

This station was established June 20, 1895, and bas been maintained during the greater 

part of each year since. ft was originally located at the old wagon bridge, one-fourth mile 

west of the railroad bridge, at Durango and about 200 feet above the Rio Grande Southern 

Railroad bridge. On June 20, 1901, the station was removed to a new bridge, located just 

below the site of the old one. 

The channel is straight for-300 feet above and 400 feet below the station. Both banks 

are high and rocky and not liable to overflow. The bed of the stream is rocky and fairly 

permanent. There is but one channel at aU stages, broken by the center pier of the bridge. 

Gage heights range from 6 to 13 feet. During the high water of 1905 such radical changes 

occurred in the channel_ as to make two rating tables necessary. 

Discharge measurements are made from the bridge to which the gage is attached. The 

initial point for soundings is the downstream edge of the right abut~ent. 

The gage at this station was read twice daily during 1905 by C. G. Graden. The original 

gage was spiked to the west side of the south end of the middle pier of the wagon bridge. 

The head of a bolt at the east abutment of the railroad bridge is 17.2.4 feet above this gage 

datum. During the early part of 1899 the old wagon bridge was removed and a new one 

was constructed a short distance below. On April I, 1899, a gage was fastened to the central pier of this bridge. Owing to this change in the location and height of the rod there is 

no apparent relation between the rating tables before and after 1899. The present gage, 

established June 20, 1901, is a vertical 14-foot timber, fastened to the southwest corne~ of 

the center masonry pier on the downstream side of the new wagon bridge, one-eighth mile 

west of the railroad station at Durango. The timber is held in place by spikes driven into 

cracks in the masonry. The gage is referred to bench marks as follows: (1) A chiseled point at the southwest corner of the center pier of the highway bridge; elevation 

16.75 feet above the zero of the gage. (2) A chiseled point on the lower side of the left 

abutment of the bridge.; elevation, 16.84 feet above the zero of the gage. On April1 and 2, 

1903, sand and gravel were washed down by Lightner Creek, which enters ab.out 100 feet 

below the bridge, and were deposited around the gage rod. On April 14, 1903, a new wire 

gage was established on the downstream side of the bridge in the span next the left bank. 

This gage was read until June 6, when it was stolen. In the meantime the sand and gravel 

had been washed from the foot of the old gage, from which readings were taken thereafter.

ANIMAS RIVER NEAR FARMINGTON, N.MEX. 

This station was established June 18, 1904. It is located at the highway bridge about 1 

mile northeast of Farmington, N. Mex. 

The channel is straight for about 900 feet above and below the station. The right bank 

is a gradually sloping gravel bar, covered with smalJ cobblestones and scattered trees and 

shrubs; it has been known to overflow, but this ts an extremely rare occurrence. The 

left bank is a flat, grassy, perpendicular bank, f> or 6 feet above low water, is lined with 

willows, and is not liable to overflow. The bed of the stream is composed of gravel, cobblestones, and silt, is free from vegetation, and is permanent The current is moderately 

swift. 

Discharge measurements are made from the downstream side of the two-span bridge to 

which the gage is attached. The initial point for soundings is the west face of the left.abutment and is marked zero with black paint on the bridge floor. 
138 STREAM 1\-lEASUREMENTS IN 1905, PART XI. 

A standard chain gage, which is read twice each day by Mrs. Adellie Ricketts, is attached 

to the downstream side of the bridge, 40 feet from the left end. The gage scale is graduated 

from 2 to 7.8 feet. The length of the chain•is 12.78 feet. The bench mark is a United 

States Geological Survey standard bench-mark tablet set into the southwest face of a 12-

inch ·cottonwood tree ltbout 50 feet north of the right end of the bridge; its elevation is 

11.13 feet above the datum of the gage and 3.17_feet below the top of the horizontal bridge 

chord on which the gage box rests. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pp. 191-195.

LA PLATA RIVER AT HESPERUS, COLO. 

This station was established June 14, 1904, in connection with investigations relating to 

the La Plata project in New Mexico. It is located at the highway bridge on the west side 

of Hesperus, Colo. 

The channel is straight for about 50 feet above and below the station. Both banks are 

low and covered with brush and scattered trees, but neither is liable to overflow. The bed 

of the stream is composed of large and small cobblestones, but is not permanent. A small 

island above the bridge, dead water at low stages, and a tortuous channPl below the bridge 

affect the accuracy of meter measurements at the bridge. The current is swift. The fall 

of the river, according to levels run by the La Plata Ditch Company for about 10 miles, is 

135 feet per mile. Gage heights range from 0.8 foot to 3.5 feet. 

Discharge measurements are made by wading at suitable points along the stream at low 

stages, as the conditions at the bridge are at some stages unfavorable to careful gagings. 

At high stages measurements are made from the wooden wagon bridge on the west side of 

Hesperus. The initial point for soundings is a nail driven into the downstream side of the 

wagon bridge over the south face of the north abutment. 

The gage was read twice daily during 1905 by Fred Harrison. The original gage-was a 

4-foot board graduated from zero to 3.9 feet. This gage was spiked to the upstream end of 

the south face of the north abutment, with the zero mark resting on the bed of the river. 

The bench mark is a nail driven horizontally into the west face of a 12-inch cottonwood tree 

about 8 inches above the ground, about 75 feet northeast of th~ gage rod, on the right bank 

of the river; elevation, 9.15 feet above the zero of the gage. On account of the boiling 

action of the water at this gage, a new staff gage was installed on April26, 1905. The new 

gage is graduated from zero to 5.2 feet and is spiked in a vertical position to the south face 

of the north abutment on the downstream side of the bridge. The datum of the new gage 

is not the same as that of the old,. being 8.09 feet below the above bench mark. 

On August 20, 1905, it was found necessary to transfer this gage to the north face of the 

south abutment downstream side of the bridge where it is now located. Elevation of gage 

datum same as that last described, viz, 8.09 feet below the bench mark. 

A description of this station, with gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geological Survey, pp. 195-196.

142 STREAM MEASUREMENTS IN 1905, PART XI. 

I,A PLATA RIVER NEAR LA PLATA, N. MEX. 

This station was established June 1, 1905, in connection with investigations relating to 

the La Plata project. It is located on the single-span wooden highway bridge 1 mile southeast of La Plata post-office, N.Mex., in sec. 3, T. 31, R. 13 W., below all points of diversion. 

The channel is straight for 50 feet above the bridge, beyond which it bends to the right; 

below the bridge it is straight for 300 feet. The left bank is well defined but is,Jiable to 

overflow at high stages. During high wat.er the right bank overflows below the bridge but 

does not overflow above. Both banks are lined with sagebrush and willows. There is but 

one channel at all stages. Gage heights range from 1 foot to 4.5 feet. At gage height of 

1 foot the river is dry. 

Discharge measurements are made from the downstream side of the bridge. 

The gage, which was read twice each day during 190.) by Frank Williams, is a vertical 

staff graduated from 3 to 10.1 feet, spiked to the northwest corner of the east abutment of 

the bridge. The 3-foot mark rests on the bed of the stream and the 9.4-foot mark is even 

with the surface of the bridge floor. The gage is referred to bench marks as follows: (1) 

The head of a 20-penny spike driven vertically into the top of the second log from the bottom at the northeast corner of Mr. ·williams's house; elevation, 21.37 feet above the zero 

of the gage. (2) A nail driven into the spur root on the south side of a cottonwood tree 

southeast of house; elevation, 19.47 feet abovP. the ZP.ro of the gage.

COLORADO RIVER DRAINAGE BASIN. '145 

LITTL1! COLORADO RIVER DRAIN AGE BASIN. 

DESCRIPTION OF BASIN. 

The country drained by the Little Colorado River consists of a high plateau with an ele.. 

vation over 4,000 feet above sea level, extending from the Continental Divide in northwestern New Mexico westward to the San Francisco M-ountains in Arizona, and from the 

Grand Canyon of the Colorado southward to the Mogollon Mesa. The greater part of this 

plateau is composed of rolling plains with a few feet of soil at the surface underlain by 

rock. Through this plateau the river winds northwestwarc! to its junction with the great 

Colorado. - ~ 

The run-off from approximately 6,000 square miles of the drainage area finds its way 

into the Little Colorado above the mouth of Rio Puerco, the largest tributary which joins 

the main stream 2 miles above the town of Holbrook, Ariz. Both the Little Colorado and 

the Rio Puerco are flashy streams, seldom clear even during low stages. They have shifting, 

sandy bottoms, and when not confined in canyons the stream beds are wide with abrupt 

·earth banks. The discharge fluctuates greatly, being insignificant in dry seasons. The 

floods at'e short and violent and carry large quantities of silt in suspension. 

LITTLE COLORADO RIVER AT 'WOODRUFF, ARIZ. 

This station was established March 16, 1905. It is loeated about 100 yards below the 

erossing of the Hoi brook-Winslow wagon road and one-fourth mile below theW oodruff dam. 

The channel is straight for 300 feet above and 100 feet below the station. The banks are 

high, with some brush, and neither is liable to overflow. The bed of the stream is composed 

of sand. The current is swift at.high and medium stages of water. 

Discharge measurements are made by means of a cable, car, and tag wire. The initial 

point for soundings is the i_ron hook on the chain connecting the cable with anchorage on 

left or west bank of stream. 

The gage is o~served twice each day by R. L. Newman. The original gage was a combined vertical and inclined rod located on the right or east bank of the stream about 60 feet 

below the measuring section. This gage was destroyed on May 3, 1905, by high water, caused 

by the breaking of the St. John and Woodruff dams. It was replaced on May 6, 1905, with 

a temporary gage, which was used until July 30, 1905, when a permanent gage was installed 

at the original location. The bench mark is a nail driven into a 6-inch cottonwood tree 

23 feet N. 10° W. from east end of gage. The original elevation of this bench mark was 

19.40 feet above the zero of the gage. This tree was so bent over by the rush of water on 

May 3 that the bench mark is about 0.05 foot lower than it was originally. The zero of the 

gage established July 30, 1905, was set 13.03 feet below the elevation of the bench mark, or 

approximately 13.07 feet below the original elevation. On July 30, 1905, the water stood at 

5.0 feet on the temporary gage set by the observer May 6, and registered 0.8 foot at the same 

time on the new permanent gage.

LITTLE COLORADO RIVER DRAINAGE BASIN. 149 

LITTLE COLORADO RIVER AT HOLBROOK, ARIZ. 

This statio:r~ wa.s established March 17, 1905. It is located at the county bridge across 

Little Colora4o River at Holbrook, Ariz. 

The chanool is straight for about 300 feet both above and below the station. A stone 

jetty along the side of the wagon road forms the right bank; the left bank is dean and 

does not overfow. The bed of the stream is sand to an average depth of 3 to 5 feet, and is 

very unstable. The entire flow of the river passes under the bridge; but as the section is 

wide the current does not always flow at right angles to the bridge. 

Discharge measurelnents are made from the downstream side of the bridge. The initial 

point for soundings is the face of the bridge abutment on west bank of stream. Soundings 

are taken at each of the floor beams. 

The gage, which was read twice each day during 1905 by Mrs. Anna Connor, is a staff 

fastened· in an upright position to the downstream face of the first pier from the west bank. 

The gage is referred to beneh marks as follows: (1) The corner of the top of the bridge pier 

to whieh the g.age is fastened; elevation, 11.80 feet above the zero of the gage. (2) The 

bottom outside edge of the bridge chord; elevation, 12.73 feet above the zero of the gage.

CHEVLON FORK NEAR WINSLOW, ARIZ. 

This station was established December 18, 1905. It is located 4~ miles above the mouth 

of the river, in sec. 34, T. 18 N., R. 17 E., 19 miles east of Winslow, Ariz. 

The channel is straight for 150 feet above and below the station. The current is very 

swift during high water. At extreme low water the current is rather sluggish, but it has a 

good velocity at ordinary stage. Both banks are practically vertical cliffs about 33 feet 

high. A dirt bank extending about 12 feet from the base of the cliff and 3 or 4 feet high has 

been deposited at the foot of the cliff on the left bank. The bed is of solid rock excepting a 

small bank of sand on the left bank which is alternately deposited and scoured out. 

Discharge measurements are made by means of a cable, car, and tagged and stay wires 

The initial point for soundings is the face of the eyebolt to which the tagged wire is fastened 

ob. the left bank of the stream. A secondary cable has been stretched across the river 100 

feet downstream from the tagged wire for use in making float measurements at very high 

stages. 

An automatic water stage register is placed on an overhanging platform 26.5 feet above 

the bed of the creek. The station is visited and the register reset once each w~k by R. L. 

Newman. The distance to the center of the first band from the top of the baseboard upon 

which the register sets is 5.90 feet; to the center of the second band, from the same point, 

9.57 feet. The base of the register baseboard is 27.30 feet above the datum of the gage.

Muddy River is a branch of the Virgin, one of the more important tributaries of the Colorado. The stream drains a long narrow strip of eountry in the eastern part of Lincoln 

County, Nev., flows southward, and joins the Virgin about 25 miles above the point where 

the latter stream enters the Colorado. 

The gaging station was established January 1, 190-±. It is located near the crossing of 

the San Pedro, Los Angeles and Salt Lake Railroad, about 6 miles downstream from Moapa, 

Nev. The station is above the Narrows and will show the amount of water available for 

storage at the proposed reservoir site in the Narrows. 

The channel is straight for 35 feet above and below _the station, and high, brush-covered 

banks slope up from the vertical sides of the channel. The immediate banks are low, but 

not liable to overflow. The bed of the stream is composed of sand and is shifting. It is 

covered with vegetation, which is kept grubbed out near the station. The current has a 

moderate velocity. 

Discharge measurements are made from a footbridge 450 feet downstream from the gage. 

The initial point for soundings is a nail driven into the downstream side of the bridge at the 

right bank. 

The gage, which was read twice each day during 1905 by J. V. Houghton, is a vertical· 

staff nailed to a post driven into the right bank. The bench mark is the top of a 2-inch post 

driven into the ground in a willow clump 20 feet from the gage on the right bank; elevation, 

9.90 feet above the zero of the gage. 

A description of this station, with gage-height and discharge d~ta, is contained in WaterSupply Paper No. 133, United States Geological Survey, pages 196-197.

Gila River rises in western and southwestern New Mexico, receiving its waters from mountains having an elevation of from 7,000 to 8,000 feet. At the point where it crosses into 

Arizona it still has an elevation of 6,000 feet. From this place it flows between mountain 

ranges, falling rapidly, until at Florence, 180 miles away, it is about 1,500 feet above sea 

level. At a point about 15 miles above Florence the river emerges upon the plains, through 

which it winds for about 75 miles before reeeiving the waters of its principal tributary, the 

Salt. From the junction of the Salt the Gila continues west and southwest and enters the 

Colorado at Yuma, Ariz., near thG southwestern corner of the Territory. 

The principal tributaries are the San Pedro and Santa Cruz rivers from the south, and 

the San Francisco, Salt, Aqua Fria, and Hassayampa rivers from the north. 

San Francisco River rises in the southwestern part of Socorro County, N. Mex., and flows 

southwestward into Graham County, Ariz., where it unites with the Gila. The basin comprises approximately 1,800 square miles of high,_mountainous country. 
GILA RIVER DRAINAGE BASIN. 159 

Salt River, though considered a tributary of the Gila, is in fact larger both in catchment 

area and in discharge. It receives the drainage from central Arizona, its principal tribu-· 

tary, the Verde, flowing southeasterly and south from th~ mountains and table-lands south 

of the Colorado River. The Verde Valley is situated in Yavapai County, Ariz., on the headwaters of the stream, and extends from a canyon above Camp Verde to a point about 10 

miles below the fort. About a mile above the junction of the Verde and 30 miles above 

Phoenix the Salt enters upon the plains of the Gila Valley. 

San Pedro River rises in the northern part of the Mexican State of Sonora, flows northward for more than 100 miles, and empties into the Gila a few miles below the town of Dudleyville, 45 miles a.bove Florence, Ariz. Rising in a country of very light snowfall, the river 

depends for the greater part of its water supply on the frequent showers of the rainy seasons. 

It flows over a sandy bed between high, steep banks, and during the dry season it shrinks 

to an insignificant stream of clear water which rises and sinks in the sand with the varying 

depth of bed rock. 

The floods of the upper Gila and its tributaries are usually short and violent, occurring 

during the months of January and February. The season of low water occurs in June and 

July. 

GILA RIVER NEAR CLIFF, N. MEX. 

This station was established September 9, 1904.- It is located 9 miles below Cliff postoffice and one-half mile below the mouth of Mangos River. It is 40 miles from Silver 

City, N.Mex. The station is best reached by stage from Silver City to Gila Store, thence 

by private conveyance. If the river is in flood, the latter part of the journey must be made 

on horseback. · 

The channel is straight for 400 feet above and 300 feet below the station. The banks 

are about 6 feet high, are clean, and are subject to overflow during extreme high water. 

The bed of the stream is composed of sand and gravel, is free from vegetation, and is shifting. There is but one channel at all stages. At low water the channel, although straight, 

cuts across the section at a slight angle; during freshets the channel will be at right angles 

to the measuring section. 

Discharge measurements are made by means of a cable and car. The initial point for 

soundings is the zero of the tagged wire. .. 

The gage is read twice each day by Mrs. Winnie P. Clark. The original gage was a staff 

fastened to a large cottonwood tree on the east side of the river. This gage was carried 

out by heavy freshets in the early part of 1905, but observations of gage heights were continued on a temporary gage until February 17, 1905, when the station was temporarily 

abandoned. On May 22, 1905, the gage was reestablished and the station put in order, 

and observations of gage heights were again begun. The bench mark is a point marked 

"U.S.G.S. B.M." with black paint in a blaze on a sycamore tree N. 84° E. 293 feet from 

the gage; elevation, 8.55 feet above the zero of the gage. 

A description of this station, with gage-height data, is contained in Water-Supply Paper 

No. 133, United States Geological Survey, page 198.

GILA RIVER AT SAN CARLOS, ARIZ. 

This station was established July 11, 1899, in connection with the investigation of the 

water supply of the Gila Valley.a It is located one-half mile south of the Indian agency at 

San Carlos and below the mouth of San Carlos Creek. 

The channel is straight for some distance above and below the station, and the water is 

comparatively swift. The right bank is high, but the left is low and liable to overflow. 

The bed of the stream IS sandy and shifting. 

Discharge measurements are made from a eable and ear a short distance above the gage 

rod. ·The gage at this station is read by R. H. Ros:i. The original gage was an inclined rod 

securely fastened to posts driYen into the left bank. During the heavy floods of January, 

February, and.March, 1905, the cable and gage were washed away, and there are breaks in 

the gage records for those months. In April and May, 1905, the station was Yisited by Mr. 

Gerard H. Matthes, who constructed an approximate gage record covering the period 

between April1 and May H, based on the data available at that time. On May 14 a chain 

gage was established on the right bank of the river about 500 feet below the new cable. In 

August, 1905, new cables were placed in position and the station was rebuilt. Owing to the 

fact that the channel left the chain gage during low water, an inclined gage was placed on 

the right bank of the stream about 60 feet above the cable for use at low stages. The zero 

of this gage coincides in elevation with the zero of the chain gage. The bench marks are as 

follows: (1) Nail in cottonwood tree on edge of bank 50 yards upstream from gage; elevation, 23.38 feet. (2) Nail in cottonwood tre~ near ditch baek of gage; elevation, 20.58 feet. 

(3) Three nails driven at the same level in three forks of old cottonwood tree on irrigating 

ditch one-third mile north of gage; elevation, 23.85 feet. Elevations are above the zero of 

the gage. This station was discontinued Deeember 31, 1905.

United States Geological Survey (Ann=Annual Report; WS=Water-Supply Paper):

164 STREAM MEASUREMEN'l'S IN 1905, PART XI. 

GILA RIVER AT DOME (GILA CITY), ARIZ. 

This station was established October 15, 1903. It is located 20 miles above the junction 

of the Gila with the Colorado. The point of gaging first established was one-fourth mile 

north of the depot at Dome. The river now flows in a channel fully 1 mile north of the 

original channel. 

The Gila carries an enormous amount of mud and sand. At times the waves of sand 

traveling along the bed of the stream are so large, the current is so swift, and the stream 

to shallow, that the water is broken into a uniform succession of waves 2 feet high and 

over. During 1905 there have been ·ten floods reaching a maximum mean discharge for 

twenty-four hours, as follows: Two floods of 95,000 second-feet or over; 1 flood of 80,000 

second-feet or over; 2 floo-of 40,000 second-feet or over; 5 floods of 13,000 second~feet 

or over. At every flood the channel shifts. The valley at its narrowest is half a mile 

wide and the waters may occupy any part or all of it. There is no place on the lower part 

of the Gila where a permanent cable can be erected at a reasonable expense. 

Up to about 8,000 second-feet discharge measurements are made by means of a boat 

and cable above that by means of floats. When the Colorado above the Gila is known 

to be constant the crest of the flood is measured after it joins the Colorado at Yuma, and 

an allowance of 5 per cent is made for flattening of the erest between Dome and Yuma. 

The gage observer is B. Rinehart. Fourteen gages have been put in by the hydrographer 

since the establishment of the station, not including temporary rods placed by the observer. 

The permanent bench mark is a standard United States Geological Survey iron post at the 

f!Outhwest corner of depot under platform, marked " 189 Y"; elevation, 189.60 feet above 

sea level and 31.97 feet above the zero of the gage.

SAN FRANCISCO RIVER AT ALMA, N. MEX. 

This station was established October 18, 1904. It is located about one-half mile south 

of Alma, N.Mex., and 85 miles northwest of Silver City. It is best reached by stage from 

Silver City, which makes the trip daily except Sundays. 

The channel is straight for about 500 feet above and below the station. The Mnks are 

about 4 feet high, are clean, and are subject to overflow during extreme high water. The 

bed of the stream is composed of gravel, is free from vegetation, and is firm and regular. 

The current is swift. • 

Discharge measurements are made by means of a cable, car, and tagged wire. The 

initial point for soundings is the zero of the tagged wire. The cable was carrie(! away by 
GILA 'RIVER DRAINAGE BASIN. 167 

a. heavy flood on March 16, 1905, but was recovered and restored at a point about 600 feet 

higher upstream on March 24. Measurements prior to March 16 were taken at the lower 

section; since then the upper section has been used. 

The gage, which is read twice each day by Mrs. Ella D. Hollimon, consists of a staff 

fastened to the east or left bank of the stream. The gage was washed out by the flood of 

March 16, 1905, but was immediately replaced in its old position. The bench mark is a 

20-penny nail driven into a blaze in a cottonwood tree 118.5 feet N. 73° E. from the gage; 

it is marked' ·u. S. G. S. B. M."; elevation above the zero of the gage, 9.06 feet. 

A description of this station with gage height and discharge data is contained in WaterSupply Paper No. 133,, United States Geological Survey, pages 206-208,

SAN PEDRO RIVER AT CHARLESTON, ARIZ. 

This station was established January 22, 1904. It is located about one-half mile west 

of Charleston station on the El Paso and Southwestern Railroad and 6 miles south of 

Fairbank, Ariz. 

The channel is straight for about 800 feet above and 500 feet below the station. Both 

banks are nearly vertical for 20 feet, are clean, and are not subject to overflow. The bed 

of the stream is composed of sand and is shifting. At high water there is but one channel, 

but at low water the channel is divided by &and bars. The current is swift. 

Discharge measurements are made at high water by a cable and car 10 feet below the gage. 

The initial point for soundings is 21 feet from the cable support on the east bank. Lowwater measurements are made by wading. 

The gage is read twice each day by H. R. Fry. The original gage was read until March 

28, 1904, when a second gage was established 200 feet upstream from the first. The second 

gage, which was read from March 29 to July 30, 1904, is in two sections: The upper section 

is attached vertically to a cottonwood t~ee on the left bank; the upper end of the lower 

section, which is inclined, is fastened to the same tree and the lower end is set in the bed of 

the stream. In July and August, 1904, floods changed the channel to such an extent that 

a third gage became necessary. This was established August 15, 1904, on the east ba;nk, 

directly opposite the old or second gage, and consists of a vertical rod fastened to a deadman in the bank at the same datum as the old gage. Readings have since been made from 

the third gage. The bench marks are as follows: (1) A United States Geological Survey 

standard iron bench-mark post near a post on the east side of the El Pase and Southwestern 

Railroad station at Charleston; elevation, 57.265 feet above the zero of the gage and 3,957.265. 

feet .above mean sea level. (2) A spike in the west side of the root of a tree on the west bank 

of the river, 100 feet above the gage; elevation, 35.860 feet above the zero of the gage and 

3,935.860 feet above mean sea level. 

A description of this station, "'ith gage-height and discharge data, is contained in WaterSupply Paper No. 133, United States Geologicai Survey, pages 208-211.

SALT RIVER AT M'DOWELL, ARIZ. 

This sta:tion was established April20, I897. It is located one-third mile above the junction of Salt and Verde rivers, 30 miles northeast of Phoenix, I5 milBs northeast of Mesa, 

and I! miles .above the Arizona canal ·diversion dam. 

The channel is straight for about 500 feet above the station. Th right bank is about 

3! feet high at the water's edge and rises with a gradual slope for 40D feet; it is clean and 

is subject to overflow. The l~ft bank rises vertically for about 5 feet at which point there 

is a small bench, from whi"ch the rocks rise to a considerable heigl t; this bank is clean 

and does not overflow. The bed of the stream is composed of san( and is shifting, and 

it is necessary to make a large number of measurements in order tp obtain an accurate 

estimate of the discharge. The current is swift . 

. Discharge measurements are made by means of a cable and car. The initial point for 

soundings is I20 feet south of the standard under the cable at the nor"h bank. Low-water 

measurements are made by wading about I,OOO feet upstream from tlhe cable, where a tag 

wire has been placed. 

Gage heights and measurements are taken by W. Richins, who df votes his whole time 

to the work. There have been five gages in use at this station, as fo lows: 

Gage No. I, set April20, I897, was a 2- by 6-inch timber bolted to tbe rocks on the south 

bank of the nvei, about one-fourth mile above the cable. Th1s gage, whiCh has smce been 

removed, was used until November 30, I899, when the station was teuporarily abandoned. 

The bench mark is a nail in a palo verde tree about 75 feet west of tL cable anchorage on 

the north bank; elevation, q.33 feet above the zero of the gage. 

Gage No. 2 was established in I901. It consists of a 2- by 6-inch timber fastened to a 

tree on the north bank of the river three-fourths mile above the caUe. The zero of this 

gage is I,323.54 feet above sea level. Its bench mark is a nail in a :oot of a willow tree, 

to which the gage is fastened; elevation, I,328.69 feet above sea level, and 5.10 feet above 

the zero of the gage. On April2, I903, high water in Verde River .Jacked ·up the water 

on gage No. 2 and changed the cross section by depositing sand. 

Gage No. 3 was installed May I9, I903. It consists of a I- by 6-L~h stadia rod spiked 

to a 2- by 4-inch timber and fastened to a tree on the south bank I! uiles above the cable. 

The water surface at this gage is about I5 feet higher than at the mou :.1 of the Verde River, 
178 STREAM. :MEASUREMENTS IN 1905, PART XI. 

and the zero of the gage is 1,336.27 feet above sea level. Three bench marks have been 

established for this gage, as follows: (1) A nail in a mesquite stump 200 feet east of Peters's 

corral; elevation, 1,363.2 feet above sea level and 26.93 feet above the zero of the gage. 

(2) A nail in the root of a mesquite tree on top of the bank 50 feet northwest of the northwest corner of Peters's corral and about 75 feet from the gage; elevation, 1,356 feet above 

sea level and 19.73 feet above the zero of the gage. (3) A nail in the willow tree to which 

the gage is attached; elevation, 1,344.27 feet above sea level and 8.00 feet above the zero 

of the gage. 

Gage No.4 was a temporary gage on the. north side of the river about 600 yards above the 

sec.tion and was read in conjunction with gage No. 3. This temporary gage, No. 4, was 

washed out by heavy floods early in 1905. 

Gage No. 5 was established because of the difficulty and time involved in reaching gage 

No.3 during high water and also because the river had changed its channel in such a way as 

to leave gage No.3 dry. It was located on the right bank of the river about one-fourth mile 

below the location of No. 3. No. 5 was read from March 10, the date of its establishment, 

to March 20, 1905, on which date it was destroyed. 

The river swept back to gage No.3, which was used until April14, when another change 

of channel rendered No. 3 useless. A temporary gage was then established at the old location of No. 4. This was observed until September 1, 1905, when a permanent gage was 

established. The zero of this gage is at an elevation of 1,326.62 feet above sea level and is 

referred to two bench marks: (1) On a mesquite tree 200 feet northwest of the gage; elevation, 1,346.12 feet above sea level. (2) A nail in tree at gage; elevation, 1,336.37 feet above 

sea level.

This station ~as established April20, 1897. It is located 30 miles northeast of Phoenix, 

15 miles northeast of Mesa, 2! niiles above the Arizona Canal diversion dam, and threefourths mile above the mouth of the river. 

The channel is straight for 300 feet above and below the ~tation, with a width of 100 

feet·at low water and 450 feet at high water. The right bank ~s high, rocky, and clean, and 

is no~ subject to overflow; the left bank is low, clean, and is ~biale to overflow. The bed 

of the strean1. is composed of sand and is shifting. The current is swift . 

. Discha¥-ge measurements are made by means of a cable, c1r, and tagged wire. At low 

water the channel is oblique to the gaging section and measu ements are made by wading 

at a point 400 feet above the cable. _

182 STREAM MEASUREMENTS IN 1905, P .ART XI. 

Gage heights are observed by W. Richins. Three gages have been in use at this station, 

as follows: 

Gage No. 1, established April 20, 1897, consisted of a vertical rod attaehed to a large 

eottonwood tree on the east bank about 60 feet below the cable. This was read until 

November 11, 1899, when the station was temporarily abandoned. The beneh mark is a 

point on a eat's claw (acacia) tree about 100 feet southeast of the gage; elevation, 27.02 

feet above the zero of the gage. 

Gage No.2 was established in January, 1901, and observations were resumed. It is an 

inclined 2- by 4-inch timber, fastened to the rocks on the west bank about 500 feet above 

the cable, the zero of the gage being 1,325.4 feet above sea level. Three bench marks were 

established for this gage, as follows: (1) A nail in a mesquite tree about 6 feet below the 

cable anchorage on the east bank; elevation, 1,345.5 feet above sea level, and 20.10 feet 

above the zero of the gage. (2) A nail in the cable standard at the east bank; elevation, 

1,341.3 feet above sea level, and 15.90 feet above the zero of the gage. (3) A mark on 

rock at the gage; elevation, 1,330.4 feet above sea level, and 5.00 feet above the zero of 

the gage. 

Gage No.3 was established May 16, 1904, on account of water piling up at No.2 during 

flood. It is a vertical rod fastened to a willow tree on the east bank about one-half mile 

above the cable. The zero of the gage is 1,339.26 feet above sea level. Two beneh marks 

were established for this gage: (1) A nail in a large cottonwood tree on the top of the east 

bank near the gage; elevation, 1,354.11 feet above sea level, 14.85 feet above the zero of 

the gage. (2) A nail in the wi1low tree to which the gage is attaehed; elevation, 1,347.26 

feet above sea level, and 8.00 feet above the zero of the gage. 

Gage No. 3, with the tree to which it was attached, was washed out during the heavy 

flood February 25, 1905. As the water showed no tendency to pile up at Gage No. 2, 

readings were resumed on that gage, which was used to the end of the year;

SANTA CRUZ RIVER AT TUCSON. ARIZ. 

This station was established October 15, 1905, by G. E. P. Smith. It is located at 

Congress Street Bridge, Tucson, Ariz. 

The channel is straight for 500 feet above and 300 feet below the station. The current· 

is swift. The left bank is low, wooded, and liable to overflow. The right bank is about 12 

feet high and not liable to overflow. The bed of the stream is composed of bowlders, 

and shifts during floods. 
186 STREAM :MEASUREMENTS IN 1905, PART XI. 

Discharge measurements are made from the bridge, which consists of one steel span 100 

feet long and four pile bents each 15 feet long. The initial point for soundings is the east 

P-dge of upstream cylindrical pier on the west bank. 

The gage is painted on the pier, which is taken as the initial point. During 1905 the gage 

was read twice each day by GeorgeS. Calliahan.

The Professional Papers, Bulletins, and Water-Supply Papers treat of a variety of 

subjects, and the total number issued is large. They have therefore been classified 

into the following series: A, Economic geology; B, Descriptive geology; C, Systematic geology and paleontology; D, Petrography and mineralogy; E, Chemistry and 

physics; F, Geography; G, Miscellaneous; H, Forestry; I, Irrigation; J, Water storage; K, Pumping water; L, Quality of water; M, General hydrographic investigations; N, Water power; 0, Underground waters; P, Hydrographic progress reports. 

Series P.-The hydrographic progress reports contain the results of stream measurements. A 

report is issued for every calendar year, containing the result'! of data collected during that year. 

These reports were first published as a part of the Director's annual report or as a bulletin; they are 

now published as water-supply and irrigation papers. The following is a list, by years, of the publications containing the progress reports of stream measurements. A detailed index of these reports 

(1888-1903) is published as Water-Supply Paper No. 119.
