INTRODUCTION.

SCOPE OF WORK.

The water supply of the United States is of more importance to the 

life and pursuits of the people than any other natural resource. In 

the arid States the limit of agricultural development is determined by 

the amount of water available for irrigation, while in all parts of the 

country the increase in the population of cities and towns makes necessary additional water supplies for domestic and industrial uses, in 

procuring which both the quantity and the quality of the water that 

may be obtained must be considered. The location of manufacturing 

plants may depend largely on the water-power facilities and on the 

character of the water. The notable advances made in the electric 

transmission of powder have led to the utilization of water powers for 

the operation of manufacturing establishments, railroads, and municipal lighting plants, many of which are at some distance from the 

places at which the power is developed.

The intelligent establishment and maintenance of enterprises or 

industries that depend on the use of water demands a thorough 

knowledge of the flowT of the streams and an understanding of the conditions affecting that flow. This knowledge should be based on data 

showing both the total flow and the distribution of the flow throughout the year, in order that normal fluctuations may be provided for. 

As the flow of a stream is variable from year to year, estimates of 

future flow can be made only from a study of observations covering 

several years. The rapid increase in the development of the water

a This report contains information similar to that published in previous years under the title 

" Report on the Progress of Stream Meisuroments,"

8 SURFACE WATER SUPPLY, 1906.

resources of the United States has caused a great demand by engineers 

for information in regard to the flow of streams, as it is now generally 

realized that the failure of many large power, irrigation, and other 

projects has been due to the fact that the plans were made without 

sufficient trustworthy information in respect to the water supply.

Owing to the broad scope of these hydrographic investigations and 

the length of time they should cover in order that the records may be 

of greatest value, it is in general impossible for private individuals to 

collect the necessary data, and as many of the streams traverse more 

than one State this work does not properly fall within the province of 

the State authorities. The United States Geological Survey has, 

therefore, by means of specific appropriations by Congress, for several 

years systematically made records of stream flow, with the view of 

ultimately determining all the important features governing the flow 

of the principal streams of the country. In carrying out this plan 

stations are established on the streams and maintained for a period 

long enough to show their regimen or general behavior. When a 

record that is sufficient for this purpose has been obtained for any 

stream, the work on that stream is discontinued. The order in 

which the streams are measured is determined by the degree of their 

importance.

During 1906 the regimen of flow was studied at about 700 stations 

distributed along the various rivers throughout the United States, as 

shown on PI. I. In addition to these records data in regard to precipitation, evaporation, water power, and river profiles were obtained 

in many sections of the country.

These data have been assembled by drainage areas and are published in a series of fourteen Water-Supply and Irrigation Papers, 

Nos. 201 to 214, inclusive, each of which pertains to the surface water 

resources of a group of adjacent areas. In these papers are embodied 

not only the data collected in the field, but also the results of computations based on these data and other information that has a direct 

bearing on the subject, such as descriptions of basins and the streams 

draining them, utility of the water resources, etc. The list follows.

« Reports containing data for years prior to 1901 are noted in the series list at the end of this paperDEFINITIONS.

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) Those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and run-oil in second-feet per 

square mile, and (2) those which represent the actual quantity of water,
10 SURFACE WATER SUPPLY, 1906.

as run-off in depth, in inches and acre-feet. They may be denned as 

follows:

"Second-foot" is an abbreviation for cubic foot per second and is 

the quantity 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.

The "miner's inch" is the quantity of water that passes through an 

orifice 1 inch 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.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, on 

the assumption that the run-off is distributed uniformly both as 

regards time and area.

"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 uniformly distributed on. the surface. It is used for comparing run-off with rainfall, 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 deliver 86,400 cubic feet, or approximately 2 acre-feet.

EXPLANATION AND USE 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 monthly and yearly discharges and run-off.

6. Tables showing discharge and horsepower and the number of 

days during the year when the same are available.

The descriptions of stations give such general information about the 

locality and equipment as would enable the reader to find and use the 

station, and the}7 also give, as far as possible, a complete history of all 

the changes that have occurred since the establishment of the station 

that would be factors in using the data collected.

The discharge-measurement table gives the results of the discharge 

measurements made during the year, including the date, name of the
INTRODUCTION. 11

hydrographer, width and area of cross section, gage height, and 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 the table represents the 

elevation of the surface of the water above the zero of the gage. At 

most stations the gage is read in the morning and in the evening.

The discharge measurements and gage heights are the base data 

from which the other tables are computed. In cases of extensive 

development it is expected that engineers will use these original data 

in making their calculations, as the computations made by the 

Survey are based on the data available at the time they are made and 

should be reviewed and, if necessary, revised when additional data 

are available.

The rating table gives the discharge in second-feet corresponding to 

various stages of the river as given by the gage heights. It is published to enable engineers to determine the daily discharge in case 

this information is desired.

In the table of 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 height 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 flow for each second during the month. Upon this the 

computations for the remaining columns, which are denned on 

page 4, are based.

The values in the table of monthly discharge are intended to give 

only a general idea of the conditions of flow at the station, and it is not 

expected that they will be used for other than preliminary estimates.

In most work where data in regard to flow are used the regimen of 

flow is of primary importance. Therefore for the principal stations 

tables have been prepared showing the horsepower that can be developed at various rates of flow, and the length of time that these rates 

of flow and the corresponding horsepower are available. These 

tables have been prepared on a basis of 80 per cent efficiency on the 

turbines, and the horsepower per foot of fall is given in order that the 

reader can determine the horsepower for any fall.

In the computations sufficient significant figures have been used so 

that the percentage of error in the tables will not in general exceed 1 

per cent. Therefore, most of the values in the tables are given to 

only three significant figures. In making the various computations 

Thatcher's slide rule, Crelle's tables, and computation machines have 

been generally used.
12 SURFACE WATER SUPPLY, 1906.

In order to give engineers an idea of the relative value of the 

various data notes in regard to accuracy are given as far as possible. 

This accuracy depends on the general local conditions at the gaging 

stations and the amount of data collected. Every effort possible is 

made to so locate the stations that the data collected will give a high 

degree of accuracy. This is not always possible, but it is considered 

better to publish rough values with explanatory notes rather than no 

data.

In the accuracy notes the following terms have been used, indicating the probable accuracy, in per cent, of the mean monthly flow. As 

these values are mean values, the error in the value for the flow of any 

individual day may be much larger.

Excellent indicates that the mean monthly flow is probably accurate to within 5 per cent; good, to within 10 per cent; fair, to within 

15 per cent; approximate, to within 25 per cent.

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. Geol. Survey) and No. 95 (Accuracy of Stream 

Measurements) . In order that those who use this report may readily 

become acquainted with the general methods employed, the following 

brief descriptions are given:

Streams may be divided, 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; and (3) 

those with constantly shifting beds. In determining the daily flow 

special methods are necessary for each class. The data on which the 

determinations are based and the jnethods of collecting them are, 

however, in general the same.

There are three distinct methods of determining the flow of openchannel 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 the 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 = c-v/^. 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
14 SURFACE WATER SUPPLY, 1906.

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 conditions.

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 flow. If dams are suitably situated and constructed, they may be utilized for obtaining reliable measurements of 

flow. 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 

water around and through the dam.

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

Preferably there should be no diversion of water through or around 

the dam. Generally, however, the 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 determinations of flow, 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 meters 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 determinations of flow will not involve, for a 

critical stage of considerable duration, the use of a head on a broadcrested dam of less than 6 inches. Moreover, when all other conditions are good, the cooperation of the owners or operators of the plant 

is still essential if reliable results are to be obtained.

INTRODUCTION. 15

A gaging station at a weir or dam has the general advantage of continuity of record through the period of ice 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 water flowing past a certain section of a stream at a given time is termed a discharge measurement. This quantity is the product of two factors 

the mean velocity and the area of the cross section. 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 water 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 accuracy. Their essential requirements are practically 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 projections of a permanent character, 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 of dams or other artificial obstructions that the gage height shall be an index of the discharge.

Certain permanent or semipermanent structures, usually referred 

to as "equipment/' are generally pertinent 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 tube 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.
16 SUEFACE WATEE SUPPLY, 1906.

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 velocity determinations are made at different points across 

the stream, and from these observations the mean velocity for the 

whole section is determined. This may be done by plotting the mean 

positions of the floats, as indicated by the distances from the bank, as 

ordinates 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 run 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 sections.

The essential parts of the current meters in use are a wheel of some 

type, so constructed that the impact of flowing water causes it to 

revolve, and a device for recording or indicating the number of revolutions. The relation between the velocity 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 which gives 

the velocity per second for any number of revolutions.

Many kinds of current meters have been constructed. They may, 

however, be classed in two general types those in which the wheel is 

made up of a series of cups, as the Price, and those having a screwpropeller wheel, as the Haskell. Each meter has been developed for 

use under some special condition. In the case of the small Price 

meter, shown in PI. II, B, 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 cable station.

In .making the measurement an arbitrary number of points are laid 

off on a 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 condition of the stream. Perpendiculars dropped from the measuring points divide the gaging section into 

strips. For each strip or pair of strips the mean velocity, area, and 

discharge are determined independently, so that conditions existing

INTRODUCTION. 17

in one part of the stream may not be extended to parts where they do 

not apply.

Three classes of methods of measuring velocity with current meters 

are in general use multiple-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.

In the vertical velocity-curve method a series of velocity determinations are made in each vertical at regular intervals, usually from 0.5 

to 1 foot apart. By plotting these velocities as abscissas and their 

depths as ordinates, and 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 by dividing the area bounded by this velocity-curve and its 

axis by the depth. On account of the length of time required to

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

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 0.2 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. On the assumption that the vertical velocity-curve is a common parabola 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 multiplepoint method gives the mean velocity very closely for open-water conditions, and moreover the indications are that it holds 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

24686 IRK 211 08 2
18 SURFACE WATEK SUPPLY, 1906.

velocity, four times the mid-depth velocity, and the bottom velocity. 

This method may be modified 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 a majority of 

the measurements. A large number of vertical velocity-curve measurements, taken on many streams and under varying conditions, 

show that the average coefficient for reducing the velocity obtained at 

0.6 depth to mean velocity is 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 

the wind or other disturbing influences. This is known as the subsurface method. The coefficient for reducing the velocity taken at 

the subsurface to the mean has been found to be from 0.85 to 0.95, 

depending on the stage, velocity, and channel conditions. The higher 

the stage the larger the coefficient. This method is specially adapted 

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 of the vertical is measured twice. It is useful 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, depends on the stage of the river, 

which is observed on the gage, and on the general contour of the bed 

of the stream, which is determined by soundings. The soundings are 

usually taken at each measuring point at the time of the discharge 

measurement, either by using the meter and cable or by a special 

pounding 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 shown in fig. 1, and the 

mean velocity, area, and discharge are determined separately for either
INTRODUCTION. 19

a single or a double strip. The total discharge and the area are the 

sums of those for the various strips, and the mean velocity is obtained 

by dividing the total discharge by the total area.

The determination of the flow of an ice-covered 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 ice. The method now employed is to make 

frequent discharge measurements during the frozen periods by the 

0.2 and 0.8, and vertical velocity-curve methods, 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, the varying thickness of ice. For information 

in regard to flow under ice cover see Water-Supply Paper No. 187.

OFFICE METHODS OF COMPUTING RUN-OFF.

There are two principal methods of determining 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 construction of a rating table, which shows 

the discharge corresponding to any stage of the stream. This rating 

table is applied to the record of stage to determine the amount of 

water flowing. The const ruction 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 the 

assumed coefficient the discharge is computed for various heads and 

the rating table constructed.

The data necessary for the construction of a rating table for a \j o

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 the quantity of water flowing. A thorough knowledge of the 

conditions at and in the vicinity of the station is also necessary.

The construction of the rating table depends on the following laws 

of flow for open, permanent channels: (1) The discharge will remain 

constant so long as conditions at or near the gaging station remain 

constant; (2) the discharge will be the same whenever the stream 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 with the stage.

FIG. 2. Discharge, area, and mean-velocity curves for Poto
INTRODUCTION. 21

The plotting of results of the various discharge measurements, using 

gage heights as ordinatcs, 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 meanvelocity 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 discharge. 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 changes 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 can be predicted, 

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 constructing the rating table.

The discharge curve is defined primarily by the measurements of 

discharge, which are studied and weighted in accordance with the 

local conditions existing at the time of each measurement. The curve 

may, however, best be located between and beyond the measurements by means of curves of area and mean velocity. 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 discharge for each tenth 

or half tenth on the gage is taken from the curve. The differences 

between successive discharges are then taken and adjusted according 

to the law that they shall either be constant or increasing.

The determination of daily discharge of streams with changeable 

beds is a difficult problem. In case there is a weir or dam available, a 

condition which seldom exists on streams of this class, the discharge 

can be determined by its use. In case of velocity-area stations frequent discharge measurements must be made if the determinations of 

flow are to be other than rough approximations. For stations with 

beds which shift slowly or are materially changed only during floods
22 SURFACE WATER SUPPLY, 1906.

rating tables can be prepared for periods between such 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 height or by Professor Stout's method, 

which has been described 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 determining the flow at stations 

where the bed shifts but slowly.

COLORADO RIVER DRAINAGE BASIN.

GENERAL DESCRIPTION.

Colorado River is formed in the southeastern part of Utah by the 

junction of Grand and Green rivers. The Green is larger than the 

Grand and is the upward continuation of the Colorado. Including 

the Green the entire length of the Colorado 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 Wj'oming, the western part of Colorado, the eastern half of Utah, practical^ 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-J>- inches. 

The streams receive their supply from the melting snows on the high 

mountains of Wyoming, Utah, and Colorado.

There are two distinct 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 vertical, step of 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 level, and is bordered on 

the east, west, and north by ranges of snow-clad mountains which
COLORADO RIVER DRAINAGE BASIN. 23

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.

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.

GREE1ST RIVER 'DRAINAGE BASIIST.

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, on the south 

and east by the White River Plateau and the Roan or Book Cliffs, 

and on the north and west by the Gros Yentre and Wyoming mountains and the great Wasatch Range. The greatest length of the 

basin, north and south, is about 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 

reservations are located in this basin in northeastern Utah.

As a matter of convenience the main river is 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 neighboring 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 into Utah. A few miles below the Wyoming-Utah boundary another sharp turn carries the river eastward along the Uinta
24 SURFACE WATER SUPPLY, 1906.

Mountains, through which it breaks near the east end of the range. 

It then flows southward in Colorado for about 25 miles, turns back 

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.

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 they 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; near Fontanelle, Wyo., it is several miles wide, with 

benches and rolling table-lands extending westward to the foothills 

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 long, 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.

In 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 east. 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.

The geology of this basin is described in the Eleventh Annual 

Report of the United States Geological and Geographical Survey of 

the Territories 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 Service and in other United 

States Geological Survey reports.

GEEEN RIVER AT GREEN RIVER, WYO.

This station was established May 2, 1895, near the pump house at 

a point about 40 feet below the bridge of the Union Pacific Railroad, 

at Green River, Wyo. Since that date it has been maintained continuously, except for a few months during the winter and during the 

year 1900. The conditions at this station and the bench marks are 

described in Water-Supply Paper No. 175, page 14, where are given 

also references to publications that contain data for previous years.

NOTE. There was probably some ice obstruction during January, February and March. During 

the high stages the gage heights obtained by the hydrographers do not agree with those recorded by the 

observer for the same dates. For this reason discharges based on the above high gage heights are 

liable to large error.

NOTE. The above values must be used with a great denl of caution as they are considered only rough 

approximations. It is probable that the discharge for January. February, and March is much too 

high owing to ice conditions, for which no corrections could be made on account of lack of data. April 

and May can be considered approximate. June is known to be far too high (compare observers' and 

hydrographers' gage heights on days of measurements), and May is probably too high, also, hut to a 

less extent. It i's believed that the remainder of the year can be accepted as fair.
30 SURFACE WATER SUPPLY, 1906.

MISCELLANEOUS MEASUREMENTS IN GREEN RIVER DRAINAGE BASIN.

Fontenelle Creek is tributarj" to Green River about 50 miles above 

Green River, Wyo.

The following measurement was made May 31, 19Ub:

Width, 40 feet; area, 99 square feet; gage height, 3.05 feet; discharge, 374 secondfeet.

NEWFORK RIVER DRAINAGE BASIN.

DESCRIPTION OF BASIN.

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 7 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.

The entire length of the Xewfork does not exceed 50 miles. The 

basin as a whole is triangular hi 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 Eastfork 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, Faj'ette, 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.

PINE CREEK NEAR PINEDALE, WYO.

This 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 April 2, 1905, was reestablished near the Hansen ranch, 

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

During 1906, discharge measurements were made from a bridge 

1 mile below the gage, where the section is more favorable. During 

the irrigating season two ditches divert water from the river between 

the gage and the measuring section. The gage is read by Mrs. J. J. 

Hansen.

The conditions at this station and the bench marks are described 

in Water-Supply Paper No. 175, page 23, where are given also references to publications that contain data for previous years.

NEWFORK RIVER DRAINAGE BASIN. 35

EAST FORK RIVER AT NEWFORK, WYO.

This station was established April 1, 1905. It was originally 

located at a point about one-third mile southeast of Newfork postoffice, in sec. 34, T. 32 N., R. 108 W. The conditions at this station 

are described in Water-Supply Paper No. 175, p. 32.

Owing to unsatisfactory conditions at this point the station was 

relocated May 1, 1906, at the county highway bridge one-fourth mile 

below.

There is but one channel, broken by two piers, and the banks are 

not liable to overflow. The bed of the stream is somewhat shifting. 

The channel is straight for 200 feet above and 100 feet below the 

station. The water is only sluggish at low stages. The river freezes 

solid during the winter.

Discharge measurements are made from the bridge. The initial 

point for soundings is at the gage on the left abutment.

The gage, which is read daily by Oliver N. Vible, is spiked to the 

left bridge abutment. The bench mark is a spike driven into the 

timber abutment of the bridge opposite the 6.50 feet mark on the 

gage.

YAMPA RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

Yampa River rises in Egeria Park, in the southeastern part of Routt 

County, Colo., runs in a generally northerly direction to Steamboat 

Springs, 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 most 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 form 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.

Elk River, Fortification Creek, Elk Head Creek, Williams River, 

and Little Snake River are the most important tributaries of the
YAMPA RIVER DRAINAGE BASIN. 37

Yampa. The upper basins of these streams are within the forested 

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

YAMPA RIVER AT STEAMBOAT SPRINGS, COLO.

This station was established May 3, 1904, at the highway bridge 

at the east end of Steamboat Springs. May 8, 1905, it was reestablished at the new steel highway bridge, about one-fourth mile below 

the old bridge, in sec. 17, T. 6 N., It. 84 W. The conditions at this 

station and the bench marks are described in Water-Supply Paper 

No. 175, page 35, where are given also references to publications that 

contain data for previous years.

bed of the stream is of sand and mud and liable to shift. There is 

one channel at all stages.

Measurements are made from the lower side of a single-span iron 

highway bridge. The initial point for soundings is the inside face of 

the south abutment.

A chain gage is fastened to the downstream guard rail; length of 

chain, 16.10 feet. The gage was read by Margaret Harrison. The 

bench mark is a chiseled cross on the top of the northwest corner of 

the south abutment of the bridge; elevation, 13.25 feet above the 

datum of the gage.

WHITE RIVER DRAINAGE BASIN.

DESCRIPTION OF BASIN.

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 topograhically 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.

Numerous 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.

The mean annual precipitation recorded at Meeker is 15.9 inches; 

farther west and at lower elevations it is undoubtedly much less.

NORTH FORK OF WHITE RIVER NEAR BUFORD, COLO.

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 conditions at this station and the bench marks are described in Water-Supply Paper No. 175, page 50, where are given also 

references to publications that contain data for previous years.

WHITE RIVER NEAR DRAGON, UTAH.

This station was established April 17, 1906. It is located at the 

toll bridge of the Uinta Stage Company, 18 miles northwest of 

Dragon, from which it is reached by stage.

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

The right bank is of shale, and high; the left bank is of earth and 

overflows at high water. The bed of the stream is composed of 

cobblestones and sand, somewhat shifting. There is one channel 

at all stages, broken by pile-bents, which somewhat disturb the current. The velocity of the current becomes very great at high stages.

Discharge measurements are made from the downstream side of 

the bridge. The initial point for soundings is on the left bank, the 

hand-rail being graduated at 5-foot intervals.

A standard chain gage was installed May 14, 1906; length of chain, 

22.65 feet. Prior to this date a staff gage was used having the same 

datum. The gages were read by J. B. Blankenship. The bench 

mark is a vertical standard Geological Survey iron post, set on the 

left bank about 75 feet downstream from the bridge; elevation, 23.85 

feet above the datum of the gage.

DUCHESNE RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

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 course marked 

by a thick line of cottonwoods.

The principal tributaries of the Duchesne 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 

by a heavy deposit of coarse river gravel and cobblestones.

Strawberry Creek, the main upper tributary of the Duchesne, drains 

an area of 1,166 square miles. The stream rises in the Uinta Mountains and the run-off is derived chiefly from melting 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 north and west, Indian, Bryants Fork, Mud, Horse, Sugar Spring, and Co-op creeks being the
54 SURFACE WATER SUPPLY, 1906.

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 purposes but is excellently 

adapted to grazing. Indian Creek 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. The greater part of the precipitation 

is in the form of snow, wrhich 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 area 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.

DUCHESNE RIVER NEAR MYTON, UTAH.

This station, established originally October 26, 1899, was reopened

April 1, 1906, in cooperation with the United States Indian Service.

It was discontinued July 10, 1906. The gage was read by H. Calvert.

The conditions at this station and the bench mark are described in

Water-Supply Paper No. 133, page 113.

The following measurement was made May 9, 1906: 

Width, 118 feet; area, 744 square feet; gage height, 7.60 feet; discharge, 2,760

second-feet.

STRAWBERRY RIVER IN STRAWBERRY VALLEY, UTAH.

This station was established May 2, 1903, and discontinued July 

12, 1906. 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 conditions at 

this station and the bench marks are described in Water-Supply Paper 

No. 175, page 61, where are given also references to publications that 

contain data for previous years.

INDIAN CREEK IN STRAWBERRY VALLEY, UTAH.

This station was established April 5, 1905, and was discontinued 

July 12, 1906. 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 Ileber, the nearest post-office. 

The records will show the amount of water that can be diverted 

from Indian Creek into the Strawberry Valley storage reservoir.

This station, established originally September 14, 1899, was 

reopened April 21, 1906, in cooperation with the United States 

Indian Service. On June 13, the bridge and gage were washed 

away, and the station was abandoned. The gage was read during 

1906 by Bert Marsing. The conditions at this station and the bench

PRICE RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

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, during 

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.

PRICE RIVER NEAR HELPER, UTAH.

This 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.

During 1906 a cable and car were installed, from which high-water 

measurements are made. The conditions at this station and the 

bench marks are described in Water-Supply Paper No. 175, page 

67, where are given also references to publications that contain data 

for previous years.

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. On the east and southeast the basin is limited 

by the high ranges of the Continental Divide, which separate it from 

the basins of Platte and the Arkansas rivers; on the north by the 

White River and Book Cliffs plateaus; on the west by the canyon 

district of the Colorado.

The tributaries include innumerable small creeks and five large 

streams Blue, Eagle, Roaring Fork, Gunnison, and Dolores rivers.

The main river is 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 direction 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 perpendicular walls varying in height up to 3,000 

feet above the water's edge, alternating with long, narrow, fertile 

valleys.

The headwater region, comprising approximately 50 per cent of 

the basin, consists of a long stretch of the western portion of the
GRAND RIVER DRAINAGE BASIN. 68

Continental Divide, extending from the north-central portion of 

Colorado southward 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 few, and, with the 

exception of Gunnison 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 the 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 from 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 mountainous portion of the basin is still well covered with 

forests of spruce, 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. . Natural 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 flat 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 number of pumping plants also draw upon this district.
64 SUBFACE WATEE SUPPLY, 1906.

Irrigation is extensively practiced in the Uncompahgre, Gunnison, 

and Grand valleys, and a large project now under construction 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 miles southwest of Grandlake post-office, in T. 3 N., R. 76 W. 

The nearest railroad station is at Granby, on the Denver, Northwestern and Pacific, 15 miles distant. The conditions at this station 

and the bench marks are described in Water-Supply Paper No. 175, 

page 70, where are given also references to publications that contain 

data for previous years.

GRAND RIVER AT HOT SULPHUR SPRINGS, COLO.

This station was established July 27, 1904. It was located at the 

highway bridge one-eighth 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.

On April 16, 1906, the station was removed to a new highway 

bridge, about 1,000 feet above the old station, where conditions are 

much more favorable for measurements.

On May 22, a standard wire gage was installed; length of chain, 

19.17 feet. The bench mark is a cross cut in the west face of a 

foundation stone near the southwest corner of the Riverside Bar 

and Cafe building, near the east end of the bridge; elevation, 20.04 

feet above the datum of the gage.

74 SURFACE WATER SUPPLY, 1906.

GRAND RIVER NEAR PALISADES, COLO.

This station was established April 9, 1902. It is located 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 

exception of one pumping plant, which takes about 20 second-feet 

from the river one-fourth mile above the station. The conditions 

at this station and the bench marks are described in Water-Supply 

Paper No. 175, page 84, where are given also references to publications that contain data for previous years.

FRASER RIVER DRAINAGE BASIN. 

FRASER RIVER, AT GRANBY, COLO.

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 eastcentral 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 conditions at this station and the bench marks 

are described in Water-Supply Paper No. 175, page 87.

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 established July 21, 1904. It is located at 

the State highway bridge on the road between Kremmling and 

Dillon, 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. 

The conditions at this station and the bench marks are described in 

Water-Supply Paper No. 175, page 96, where are given also references 

to publications that contain data for previous years.

GRAND RIVER DRAINAGE BASIN. 81

EAGLE RIVER DRAINAGE BASIN. 

EAGLE 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 cascades, the average slope above the mouth of 

Roche Moutonnee Creek being 150 feet per mile. The rocks are about 

equally divided between metamorphic granites and sedimentary formations. The forest cover is excellent, 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 less 

accentuated, the elevations varying from 7,000 to 11,000 feet. The 

rocks are largely sedimentary, erosion is greater, and the forest cover 

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 divert 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.

The gaging station was established March 12., 1905. It is located 

at Rule's private road bridge, in T. 5 S., R. 85 W., 1\ miles below 

Eagle, Colo. The chief object of the station is the collection of power 

data. The conditions at this station and the bench marks are described in Water-Supply Paper No. 175, page 98.

ROARING FORK DRAINAGE BASIN. 

ROARING FORK AT GLENWOOD SPRINGS, COLO.

This station was established April 6, 1906. It is located at a 

single-span wooden highway bridge about 500 feet above the mouth 

of Roaring Fork in the city of Glenwood Springs.

The channel is straight; the right bank is low and overflows at 

extreme high water, the left is high. The bed of the stream is rough 

and is composed of cobblestones and bowlders. There is but one 

channel at all stages and the current is swift.

Discharge measurements are made from the downstream side of 

the bridge. The initial point for soundings is at the right abutment.

A chain gage, which was read during 1906 by Mrs. C. S. Linsley, 

is attached to the downstream hand rail; length of chain, 20.44 feet. 

The bench mark is a cross cut in the upper surface of the first stone 

below the capstone of the east masonry abutment, upstream side; 

elevation, 12.94 feet above the datum 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, descend through narrow 

mountain valleys, and unite about 12 miles above Gunnison. From 

the junction of these rivers the Gunnison flows west and southwest 

to the point where it enters Grand River 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 Black Canyon of the Gunnison, through which it winds 

in a tortuous course for 56 miles between granite walls that rise precipitously 3,000 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 narrow 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 drawn through the town of Hotchkiss.

The soil of the lower valleys is chiefly adobe, and the higher 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 piiioii pines and cedars along the foothills. In the 

valleys chico and sagebrush form the controlling vegetation, except 

along the streams, which are bordered to some extent by cottonwood, 

willow, and undergrowth.
86 SUEFACE WATEE SUPPLY, 1906. >

The chief tributaries of the Gunnison are Ohio, Tomichi, Lake 

Fork, and Cimarron creeks and Smith, North Fork, and Uncompahgre rivers, North Fork being the largest.

North Fork rises in the Huntsman Hills, 20 miles south of Glenwood Springs, flows in a general south and southwesterly 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 5,500 feet above 

sea level. The higher peaks are formed of granitic rocks, but lower 

down sedimentary formations occupy at least 80 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 junction 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 occupies 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 conspicuous features of this plateau. 

The relief features are terraced mesas flanked by shale buttes and 

ridges, trenched by deep, narrow canyons. Uncompahgre Valley 

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 creeks are perennial streams, 

but almost their entire volume is diverted for irrigation during the 

growing season, 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, and the Gunnison 

tunnel will divert water from the mountainous area and transmit it 

to Uncompahgre Valley, which has been an irrigated district since 

the early eighties.

GUNNISON RIVER AT EAST PORTAL OF GUNNISON TUNNEL, COLO.

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. 7 "W., 21 miles by wagon 

road from Montrose. The object of the station is to determine the 

volume of flow of the river at this point, as 1,300 second-feet will be 

diverted by the Gunnison tunnel when it is completed. The conditions at this station and the bench marks are described in WaterSupply Paper No. 175, page 108.

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 Grande Railroad. It 

was intended that this station should replace that formerly maintained on the Gunnison at Grand Junction, which was abandoned on 

account of conditions that rendered accurate gagings impossible. The 

conditions at this station and the bench marks are described in 

Water-Supply Paper No. 175, page 112, where are given also references to publications that contain data for previous years.

94 SUEFACE WATER SUPPLY, 1906.

UNCOMPAHGRE RIVER AT DELTA, COLO.

This station was established April 29, 1903. It was originally 

located at a highway bridge one-fourth mile above the Denver and 

Rio Grande Railroad bridge, but on November 17, 1903, the station 

was removed to the Denver and Rio Grande Railroad bridge, onefourth mile northwest of the Denver and Rio Grande Railroad station, in order that the measured discharge of the river might include 

the mill-ditch waste. Excluding the discharge of seasonal high 

water in May or June and an occasional rise from local storms, the 

water passing this station is entirely seepage water from irrigation 

above. The conditions at this station and the bench marks are 

described in Water-Supply Paper No. 175, page 125, where are given 

also references to publications that contain data for previous years.

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 flows 

southwestward, passes across the northwestern corner of Arizona, 

then turns to the south and for the remainder 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 

Nile 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 Nile and Susquehanna rivers. The Nile is similar 

in type, while the Susquehanna shows the difference in flow 

between arid and humid regions. In the 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
96 SURFACE WATER SUPPLY, 1906.

Nile have been used. The Colorado has been taken as the standard 

of comparison.

The Nile has 5.7 times the drainage area and the Susquehanna 

about one-eighth the area of the Colorado.

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 run-off to rainfall in the Nile 

basin is 2 times smaller; that of the Susquehanna basin is 8.2 times 

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 secondfeet 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. K. 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 volume of flow 

of the Colorado, and of the year's silt 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 miles 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 San Juan, Little Colorado, Williams Fork, and Gila rivers,
COLORADO RIVER. 97

ivhich enter from the east, and Virgin River, which enters from the 

^est. With the exception of Virgin River and Williams Fork, these 

streams and their various tributaries are described in other parts of 

^his report.

COLORADO RIVER AT HARDYVILLE, ARIZ.

This station was established May 11, 1905. 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 conditions at this station and the bench marks 

ire described in Water-Supply Paper No. 175, page 128.

SAN JUAN RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

San Juan River rises among the snow masses that crown the high 

peaks of the San Juan Mountains in southwestern Colorado, flows 

southwestward into New Mexico, then swings to the west and northwest, passing from San Juan County, N. Mex., across the extreme 

southwestern corner of Colorado into San Juan County, Utah, in the 

southwestern part of which it unites with the Colorado.

For the first 75 miles of its course the San Juan is a typical mountain stream, but at Canyon Largo, N. Mex., where it turns westward, 

its character changes, and it occupies a broad, winding, sandy channel in an arid valley, bordered on each side by terraced mesas. Below 

the mouth of Mancos River the valley narrows and the river bottom 

is bounded by abrupt bluffs, broken and cut by dry water channels, 

and merging farther on into the walls of a deep, narrow, box canyon 

in which the river flow^s to its end.

The drainage area includes portions of four States and Territories. 

Its topography ranges in type from mountainous at the headwaters in 

Colorado to the types exemplified in the valleys, plateaus, and eroded 

mesas of Utah, New Mexico, and Arizona. Large areas of eruptive 

rocks occur in the highest portions of the basin, but the predominating formations are of sedimentary origin. The headwater streams are 

protected by fine forests of spruce and yellow pine and, at lower elevations, large areas of aspen. The lower basin is practically barren 

except for an extensive growth of sagebrush, scattered cedars, pinons, 

and range grasses.

The principal tributaries of the San Juan are Navajo, Piedra, Pine, 

Florida, Animas, and La Plata rivers, the Animas being the most 

important.

Animas River has its source in the region above Silverton, draining 

portions of the Needle and La Plata mountains, the former being the
100 SURFACE WATER SUPPLY,, 1906.

most rugged of the Rocky Mountain ranges. The river flows southward to the Colorado-New Mexico line and thence southwestward to 

the point where it joins the San Juan at Farmington, N. Mex. The 

upper portion of the basin, above Durango, is very mountainous and 

furnishes the greater part of the run-off. This region is generally 

well timbered with pine, spruce, and aspen, but large areas consist of 

naked granite peaks. Immediately above and below Durango the 

valley broadens and is bordered by mesas and bluffs cut by narrow 

canyons and covered with sagebrush and scattered pines and pinons; 

along the stream channels cottonwoods predominate. The rocks of 

this region are chiefly of sedimentary origin. The soils of the lower 

valleys consist of sandy loam and are very fertile.

La Plata River rises in the granite masses known as La Plata Mountains, about 25 miles northwest of Durango, Colo., and flows southward to its point of junction with the San Juan. Its drainage basin 

is a narrow strip parallel to and adjoining the Animas basin. The 

upper portion of the basin is a well-watered and forest-clad mountain region which merges southward into an arid mesa, plateau, and 

canyon country. La Plata Valley proper is a narrow, shallow depression from Hesperus down, bounded on both sides by high, broken 

table-lands and deeply eroded mountains. The lower mountain 

slopes are covered with pinon, scrub oak, and cedar; the lower valleys 

support heavy growths of sagebrush and chico; the upper mountain 

slopes were at one time heavily timbered with spruce and yellow and 

white pine, but these forests have been largely removed by lumbermen.

The other tributaries of the San Juan need not here be described. 

Those mentioned are perennial streams but much of their water is 

diverted for irrigation and never reaches the main river. In addition 

to the perennial streams are many intermittent creeks throughout 

New Mexico which contribute large volumes of water during heavy 

storms.

Much land is now under cultivation along the valleys of the San 

Juan, Animas, Pine, Florida, and La Plata rivers and the smaller 

tributaries in Colorado. Numerous small lakes high up in the mountains tend to equalize the flow of some of the tributaries, and many 

large and small storage-reservoir sites are available which will in time 

be developed. 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 June 18, 1904, and discontinued 

September 22, 1906. It was first located near the Methodist Indian 

school about 3 miles south of Farmington; N. Mex. ; and about 2 miles
SAN JUAN RIVER DRAINAGE BASIN. 101

below the mouth of Animas River. On May 11, 1906, it was removed 

to the new suspension bridge, which replaces the old one, about 1J 

miles above the original location.

Measurements are made from the bridge; the initial point for 

soundings is the inside face of the south pier.

The new gage, which was read during 1906 by Samuel Thomalson, 

consists of a cantilever arm, to which a standard chain gage is attached; 

length of chain, 6.80 feet. The bench mark is a' 20-penny spike 

driven horizontally into a crevice in the sandstone ledge about 30 

feet upstream from the gage; elevation, 9.61 feet above the datum 

of the gage.

SAN JUAN RIVER DRAINAGE BASIN. 103

LA PLATA EIVEE NEAE LA PLATA, N. MEX.

This station was established June I, 1905, in connection with investigations relating to 'the La Plata project, and discontinued Sept. 

24, 1906. It was 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. After June 4, 1906, gage 

heights were found by measuring down from a reference point on the 

floor of the bridge by a rod graduated to read the height directly. 

The conditions at this station and the bench marks are described in 

Water-Supply Paper No. 175, page 142.

104 SURFACE WATER SUPPLY, 1906.

LITTLE COLORADO RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

The country drained by the Little Colorado River consists of a 

high plateau with an elevation over 4,000 feet above sea level, 

extending from the. Continental Divide in northwestern New Mexico 

westward to the San Francisco Mountains 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 northwestward 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 are short and violent and carry large quantities of silt in suspension.

LITTLE COLOEADO EIVEE AT WOODEUFF, AEIZ.

This station was established March 16, 1905. It is located about 

100 yards below the crossing of the Holbrook-Winslow wagon road 

and one-fourth mile below the Woodruff dam. The conditions at 

this station and the bench marks are described in Water-Supply 

Paper No. 175, page 145.

The station equipment which was carried awray by the flood of 

November 26 and 27, 1905, was replaced March 24, 1906. A new 

cable 210 feet long, car, and tag wire were erected, also a combined 

vertical and inclined rod was placed in the same location as the old 

one.

The bench marks previously used were replaced by the following: 

Bench mark No. 1 is the head of a bolt in a scar in a tree, to which 

the second inclined section is fastened; elevation, 14.92 feet. Bench 

mark No. 2 is the head of a bolt in a scar on the river side of the 

fifth cottonwood tree south in a row, to which the last section of the 

gage rod is fastened; elevation, 23.02 feet. Elevations refer to the 

datum of the gage.

110 SURFACE WATER SUPPLY, 1906.

LITTLE COLORADO RIVER AT ST. JOHNS, ARIZ.

This station was established April 18, 1906. It is located at the 

south end of the town of St. Johns, one-half mile above the dam and 

county bridge.

The channel is straight for 300 feet above and 250 feet below the 

station. There is a good velocity at all stages, becoming swift at 

high water. The banks are clean and almost perpendicular, and 

will not overflow during high water. The bed of the stream is clean, 

and sandy; it probably shifts slightly. There is one channel at all 

stages.

Discharge measurements are made by means of a cable, car, and 

tagged wire. A stay wire is used for high-water measurements. The 

initial point for soundings is the face of the cable support on the right 

bank.

The staff gage, which is read by the local hydrographer, W. D. 

Rencher, is bolted to the framework built out over the bank on the 

right side of the river at the gaging station. The bench mark is the 

head of a bolt driven into solid ledge 73 feet northeast from the cable 

support on the left bank; elevation, 15.43 feet above the zero of the 

gageDischarge measurements of Little Colorado River at St. John, Ariz., by Reed and Rencher,

in 1906.

SILVEE CREEK AT SNOWFLAKE, AEIZ.

This station was established May 4, 1906. It is located at the 

southeast end of the town and 2 miles below the dam of Snowflake 

and Taylor Irrigation Company. All water is shut off by the dam 

during the entire irrigation season, excepting when rains occur.

The channel is straight for 200 feet above and 150 feet below the 

station. The current is good at all stages. The right bank is high, 

sandy, and clean; the left is sandy, is higher than the right and is 

covered with small willows which serve to hold the soil in place. 

Owing to the level country and the sudden rains to which this creek 

is subjected, both banks will probably overflow during extreme high 

water. The bed of the stream is sandy, level, and clean. There is 

one channel at all stages, except when the banks overflow and then 

water is liable to extend over a large area.

Discharge measurements are made by means of a cable and car during high water and by wading at low stages. The initial point for 

soundings is the first tag wire from the support on the right bank.

The gage, which is read by J. W. Smith twice each day, is a combined vertical and inclined rod on the right bank of the stream at 

the point of measurement. The bench mark is the head of a bolt in 

the trunk of a large cottonwood tree 400 feet northeast from the rod; 

elevation, 16.68 feet above the zero of the gage.

Discharge measurements of Silver Creek at Snowflake, Ariz., by Reed and Newman, in 1906.

SILVER CREEK AT CANYON STATION NEAR SNOWFLAKE, ARIZ.

This station was established May 2, 1906. It is located at the 

mouth of Silver Creek canyon just below the town of Snowflake. It 

was established principally to determine the flood waters of Silver 

Creek and Cottonwood Wash, which can not be taken care of by the 

station above. At times Cottonwood Wash carries more water than 

the main stream.

During the irrigation season the stream is entirely shut off above 

the Snowflake and Taylor Irrigation Company's dam, 3 miles above. 

All water passing the section during this period is waste and seepage 

water.

The channel is straight for 500 feet above and 600 feet below the 

station. The current is very swift at high water. Both banks are 

high, are strewn with bowlders, and will not overflow. The bed of the 

stream at the cable section is of gravel and sand formation. Above 

and below the cable the bed is covered with cobblestones.

Discharge measurements are made by means of a cable, car, and 

tagged wire. The initial point for soundings is the first tag on a wire 

at the right bank.

The gage is a series of inclined rods bolted to solid rock on the right 

bank of the canyon 100 feet above the gaging section. Bench mark 

No. 1 is a cross cut into a point of ledge to which the rod is bolted at 

elevation 26.01 feet above the zero of the gage.

and Newman, in 1906.

LITTLE COLORADO RIVER DRAINAGE BASIN. 115

CHEVELON FORK NEAR WINSLOW, ARIZ.

This station was established December 18, 1905. It is located 

above the mouth of the river, in sec. 34, T. 18 N., R. 17 E., 19 miles 

east of Winslow, Ariz. The conditions at this station and the 

bench marks are described in Water-Supply Paper No. 175, page 157.

A staff gage was set about 25 feet upstream from the automatic 

water stage register on May 14, 1906. The bench mark is a bolt in 

a rock between the cable and automatic register; elevation, 28.375 

feet above zero of both gages.

On October 1, 1906, a well point and 10 feet of 2-inch pipe was 

laid from the bottom of the tube out into the stream and securely 

connected to the bottom of the creek and to the float tube. This 

obviates the trouble caused by sand collecting in and about the 

bottom of the float tube.

CLEAR CREEK NEAR WINSLOW, ARIZ.

This station was established June 13, 1906. It is located 6 miles 

from Winslow and 3 miles above the Clear Creek Irrigation Company's 

dam and the county bridge. It is one-half mile above the pump 

house.

The channel is straight for 250 feet above and 500 feet below the station. The current is good at all stages. Both banks are perpendicular cliffs and will not overflow. The bed of the stream is strewn with 

large bowlders and is permanent. There is one channel at all stages.

Discharge measurements are made by means of a cable, car, and 

tagged wire. A stay wire is used for high-water measurements. The 

initial point is the first tag at the eyebolt to which the tag wire is 

fastened.

The gage, which is read by E. McFarland, is an automatic waterstage register on a shelf 51 feet above the bottom of the creek. There 

is also a staff gage 42 feet long bolted to the cliff. The elevation of 

both gage zeros is the same. The bench mark is a bolt in a wooden 

plug which has been driven into a hole in the solid ledge 5 feet south of 

the gage rod; elevation, 35.083 feet above the gage zero.

Imel, in 1906.

WOODRUFF DITCH NEAR WOODRUFF, ARIZ.

Woodruff ditch diverts water from the north side of Little Colorado 

River at the point where provision is made for the overflow of the 

surplus water. The sill of the intake gate is slightly raised above the 

crest of the spillway.

This water so diverted is used to irrigate lands on the north side of 

the river in and about the town of Woodruff and takes practically the 

entire flow during the low-water season.

Measurements are made just below the canal headgate.

120 SURFACE WATER SUPPLY, 1906.

VIRGIN RIVER DRAINAGE BASIN.

MUDDY RIVER NEAR MOAPA, NEV.

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 country 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, 1904. 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 conditions 

at this station and the bench marks are described in Water-Supply 

Paper No. 175, page 157, where are given also references to publications that contain data for previous years.

GILA RIVEE DRAINAGE BASIN. 121

GILA RIVER DRAINAGE BASIN. 

DESCRIPTION OF BASIN.

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 receiving 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 

the 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.

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 tributary, the Verde, 

flowing southeasterly and south from the mountains and table-lands 

south of 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 above 

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.
124 SURFACE WATER SUPPLY, 1906.

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 so shallow, that the 

water is broken into a uniform succession of waves 2 feet high and 

over. The conditions at this station and the bench marks are 

described in Water-Supply Paper No. 175, page 164, where are 

given also references to publications that contain data for previous 

years.

SAN PEDKO KIVEK AT CHARLESTON, AKIZ.

This station was established January 22, 1904, and was discontinued September 6, 1906. It is located on the El Paso and Southwestern Kailroad about one-half mile west of Charleston station and 

6 miles south of Fairbank, Ariz. The conditions and the bench 

marks are described in Water-Supply Paper No. 175, page 170, where 

are given also references to publications that contain data for previous years.

On February 23, 1906, the cable was moved 70 feet upstream, 

where channel conditions are the same. The initial point is the 

first tag on a wire at the face of the cable support on the right bank. 

A wash comes in just below the station, but carries water only in time 

of heavy rain and then only for a few hours. The amount carried 

can be easily measured.

SALT RIVER AT ROOSEVELT, ARIZ.

This station was established February 7, 1901. It is located at 

the town of Roosevelt, which is the United States Reclamation Service construction camp for the Salt River dam and reservoir, and is 

about 12 miles west of Livingston; Ariz. The conditions at this station are described in Water-Supply Paper No. 175, page 173, where 

are given also references to publications that contain data for previous years.

During September, 1906, this station was reequipped with a cable 

and car at a point about 500 feet below the Roosevelt dam site.

During the flood of December 3 to 5, 1906, the gage rod which had 

been in use since the construction on the dam was begun, was carried 

away. From December 3 to 15, 1906, the readings were taken on 

the upper gage about 1,000 feet above the dam. A new rod was 

established at the same location as the one carried away, on December 17, 1906, with the zero at the same elevation as the old gage.

SANTA CRUZ RIVER AND DITCHES 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 conditions at this station and the bench marks are described in WaterSupply Paper No. 175, page 185.

Manning and Farmers ditches divert practically the entire flow 

during the low period of Santa Cruz River. These ditches are taken
140 SURFACE WATER SUPPLY, 1906.

out just above the gaging station, and their flow is determined by 

current-meter measurements, supplemented by daily records kept by 

the ditch management, as to the amount of water contained in each. 

This water is used to irrigate lands on the north and south sides of 

Santa Cruz River in and about the vicinity of Tucson.
