AUTHOKIZATION AND SCOPE OP WOKK.

This volume is one of a series of 14 reports presenting records of 

measurements of flow made onj streams in the United States during 

the years ending September 30^ 1919 and 1920.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat. L., p. 394):

Provided, That this officer [the Director] shall have the direction of the Geological 

Survey and the classification of public lands and examinatiop of the geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation in the arid West. Since the fiscal year ending 

June 30, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriations:

 For gaging the streams and determining the water supply of the United States, and 

for the investigation of underground currents and artesian wells, and for the preparation of sports upon the best methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June .W, 1895-1921.

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 5,

Measurements of stream flow have been made at about 5,000 points 

in the United States and also at many points in Alaska and 1}he 

Hawaiian Islands. In July, 1920, 1,350 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many
2 SURFACE WATER SUPPLY, 1919-1920, PART VH. . t

miscellaneous discharge measurements are made at other points. In 

connection with this work data were also collected in regard to precipitation, evaporation, storage reservoirs, river profiles, and water 

power in many sections of the country and will be made available in 

water-supply papers from time to time.

DEFINITION OF TERMS.

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 that represent a rate of flow, as secondfeet, gallons per minute, miners' inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

of water, as run-off in inches, acre-feet, and millions of cubic 

feet. The principal terms used in this series of reports are 

second-feet, second-feet per squar6 mile, run-off in inches, and acrefeet. They may be defined as follows :

^ Second-feet" is an abbreviation for "cubic feet per second." 

A second-foot is the rate of discharge of water flowing in a channel / 

of rectangular cross section 1 foot wide and 1 foot deep at an average <

velocity of 1 foot per second. It is generally used as a ^

unit from which others are computed. /-/

"Second-feet per square mile" is the average number of eoMc 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. S

"Run-off in inches" is the depth to which^n area would be 

covered if all the water flowing from it in a.giveu period were uniformly distributed on the surface. It isjused for comparing run-off 

with rainfall, which is usually expressed in depth in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The following terms not in common use are here defined :

"Stage-discharge relation;" an abbreviation for the term "relation 

of gage height to discharge. "

"Control;" a term used to designate the natural section or stretch 

of the channel or artificial structure below the gage that determines 

the stage-discharge relation at the gage. It should be noted that 

the control may not be the same section or sections at all stages. . The "point of zero flow" for a given gaging station is that point 

on the gage the gage height at which water ceases to flow over 

the control.

EXPLANATION OP DATA.

The data presented in this report cover the biennium beginning 

October 1, 1918, and ending September 30, 1920. At the beginning 

of January in most parts of the United States much of the precipitation in the preceding three months is stored as ground water, in the 

form of snow or ice, or in ponds, lakes, and swamps, and this stored 

water passes off in the streams during the spring break-up. At the 

end of September, on the other hand, the only stored water available for run-off is possibly a small quantity in the ground; therefore the run-off for the year beginning October 1 is practically all 

derived from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a staff gage or from a water-stage recorder that 

gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter. (See Pis. I, II.) The 

general methods are outlined in standard textbooks on the measurement of river discharge.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage, and these rating tables, when applied to the gage heights, give the discharge from which the daily, 

monthly, and yearly means of discharge are determined.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving 

records of discharge measurements, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge 

and run-off.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and records of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the permanence of the stage-discharge relation, covering such subjects as the occurrence of ice, the use of the 

stream for log driving, shifting of control, and the cause and effect 

of backwater; it gives also information as to diversions that decrease the flow at the gage, artificial regulation, maximum and minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in 

second-feet corresponding to the mean of the gage heights read each 

day. At stations on streams subject to sudden or rapid diurnal 

fluctuations the discharge obtained from the rating table and the mean
4 SURFACE WATER SUPPLY, 1919-1920, PART VII.

daily gage height may not be the true mean discharge for the day. 

If such stations are equipped with water-stage recorders the mean 

daily discharge may be obtained by averaging discharge at regular 

intervals during the day or by using the discharge integrator, an 

instrument operating on the principle of the planimeter and containing as an essential element the rating curve of the station.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow for the day when the mean gage height was 

highest. As the gage height is the mean for the day it does not 

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

given in the maximum column. Likewise, in the column headed 

"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 in cubic feet per second during the month. On 

this average flow computations recorded in the remaining columns; 

which are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends primarily (1) on the 

permanency of the stage-discharge relation and (2) on the accuracy 

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refinement of gage readings, (4) frequency of gage readings, and (5) 

methods of applying daily gage height to the rating table to obtain 

the daily discharge.

For the rating tables "well defined" indicates, in general, that 

the rating is probably accurate within 5 per cent; "fairly well 

defined," within 10 per cent; "poorly defined," within 15 to 25 

per cent. These notes are very general and are based on the plotting 

of the individual measurements with reference to the mean rating 

curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth of run-off in inches 

may be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of 

information concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of .artificial regulation of 

the flow of the river above the station. "Second-feet per square 

mile" and "run-off in inches" are therefore not computed if such
DIVISION OF WORK. 5

errors appear probable. The computations are also omitted for 

stations on streams draining areas in which the annual rainfall is 

less than 20 inches. All figures representing " second-feet per square 

mile" and "run-off in inches" previously published by the Survey 

should be used with caution because of possible inherent sources 

of error not known to the Survey.

Many gaging stations on streams in the irrigated sections of the 

United States are located above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development as prior appropriations below the 

stations must first be satisfied. To give an idea of the amount of 

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary estimates; the tables of daily discharge allow more detailed 

studies of the variation in flow. It should be borne in mind, however, that the observations in each succeeding year may be expected 

to throw new light on data previously published.

COOPERATION.

The United States Forest Service furnished winter readings on 

East Fork of Arkansas River and Tennessee Fork near Leadville, 

Colo. It also furnished the services of a hydrographer during the 

winter.

In Oklahoma the United States Reclamation Service paid a part of 

the expense of maintaining the gaging station on Medicine Bluff 

Creek near Lawton. The services of a gage reader on Little Medicine 

Bluff Creek near Lawton were furnished by the sanitary corps of the 

United States Army.

The station on Neosho River near lola, Kans., was maintained in 

cooperation with the Kansas Water Commission, H. A. Rice, secretary.

DIVISION OF WORK.

Data for stations in Colorado and Oklahoma were collected and 

prepared for publication under the direction of Robert Follansbee, 

assisted by P. V. Hodges, J. B. Spiegel, T. J. Watkins, and Miss Esther 

M. Dye.

Data for the station on Neosho River near lola, Kans., were collected and prepared for publication under the direction of R. C. Rice, 

district engineer, assisted by E. L. Grant and A. K. (rowans.

RECORDS AVAILABLE. May 10 to October 31, 1890; June 18 to October 16, 1903; 

February 8, 1911, to September 30, 1920.

GAGE. Vertical staff on downstream side of left bridge abutment: read by Fred 

Coquoz during summer and by forest ranger during winter. Datum lowered 

0.40 foot October 6, 1911. Relation between present gage and gages used in 1890 

and 1903 not known.

DISCHARGE MEASUREMENTS. Made by wading or from bridge.

CHANNEL AND CONTROL. Bed rough and composed of small boulders. Control a 

short distance below gage at rapids, which shifts slightly at long intervals. Banks 

not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 1.10 feet August 1 (discharge, 149 seconq\-feet); no record during period 

of highest discharge; minimum stage, 0.25 foot March 27 (discharge, 4 second1 feet).

Maximum stage recorded during year ending September 30, 1920, 2.0 feet at 

10 a. m. May 26 and 27 (discharge, 430 second-feet); minimum discharge occurred 

during winter.

1911-1920: Maximum discharge recorded, 448 second-feet at 8 a. m. May 24, 

1914; minimum discharge measured 1.3 second-feet on January 14, 1915.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Court decrees for diversions of 8 second-feet above the station; also a 

decree for diversions of 18.5 second-feet from the basin of Eagle River through 

Ewing ditch to that of Tennessee Fork above station. During 1919, 1,830 acrefeet, and during 1920, 2,000 acre-feet were diverted.

ACCURACY. Stage-discharge relation shifted slightly. Rating curve well defined 

between 8 and 250 second-feet; applied indirectly for shifting control from July 1, 

1919, to August 15, 1920. Gage read to hundredths twice daily. Daily discharge

CHANNEL AND CONTROL. Bed composed of boulders; very rough. Control short

distance below gage; shifts at long intervals. Banks not subject to overflow. 

EXTREMES or DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 1.65 feet at 6 a. m., May 27, 28, 29, and 30 (discharge, 240 second-feet);

minimum stage recorded, 0.30 foot at 6 a. m. April 10 (discharge, 20 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 1.9 feet at

6 a. m. June 12 (discharge, 342 second-feet); minimum stage, 0.25 foot, April 21

and 22 (discharge, 19 second-feet).

1911-1920: Maximum stage recorded, 2.2 feet at 6 a. m. June 18, 1917 (discharge, 467 second-feet); minimum discharge, 10 second-feet April 9 and 19, 1914. 

ICE. Stage-discharge relation not affected by ice; hot springs keep creek open. 

DIVERSIONS. Court decrees for diversions of 148 second-feet from Cottonwood Creek,

of which 28 second-feet are above gaging station. 

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. Gage

read to hundredths twice daily. Daily discharge ascertained by applying mean

daily gage height to rating table. Records good.

30 SURFACE WATER SUPPLY, 1919-1920, PART VII.

WEST BEAVER CREEK NEAR VICTOR, COLO.

LOCATION. In sec. 30, T. 16 S., R. 68 W., at Skaguay power station of Arkansas 

Valley Railway, Light & Power Co., 7 miles southeast of Victor, Fremont County.

DRAINAGE AREA. 70 square miles.

RECORDS AVAILABLE. January 1, 1905, to September 30, 1920.

DETERMINATION OF DISCHARGE. Water used through power house is brought by 

pipe line from reservoir 3J miles upstream; quantity measured hourly by weir, 

and a quantity representing the gain or loss in the reservoir during the period 

is added or subtracted. To determine the natural flow of the stream the seepage 

through the dam is measured by weir and added to the total quantity thus obtained. This method takes no account of evaporation from the surface of the 

reservoir.

DIVERSIONS. Above the power reservoir are three reservoirs from which the town 

of Victor obtains its municipal supply. In the upper basin are four reservoirs 

from which water is diverted through St. John tunnel into Lake Moraine, and 

thence by natural channels to Colorado Springs, where it is used as municipal 

supply. During 1919, 1,840 acre-feet were diverted through St. John tunnel 

and during 1920, 2,180 acre-feet. Below the power plant adjudicated decrees 

for diversions of 126 second-feet from Beaver Creek, which is formed by East and 

West Beaver creeks. In addition, there is an irrigation reservoir in operation 

which has a filing for 4,760 acre-feet.

COOPERATION. Records are furnished through courtesy of Arkansas Valley Railway, Light & Power Co.

BOEHMER CREEK NEAR PIKES PEAK, COLO.

LOCATION. In NW. J sec. 32, T. 14 S., R. 68 W., 3J miles south of Pikes Peak, El Paso 

County, above Little Beaver and Sackett creeks. Elevation of station, 11,000 

feet.

DRAINAGE AREA. 7.2 square miles (measured on topographic map). About 75 per 

cent of this area is above timber line. To the natural drainage has been added 

that of West Beaver Creek above intake of Strickler tunnel.

RECORDS AVAILABLE. October 1, 1909, to September 30, 1920.

DETERMINATION OP DISCHARGE. Flow measured by sharp-crested weir, 60 inches 

long, with complete end contraction. A stake is driven into bed of stream in 

pool above weir, so that its head is level with crest of weir; depth of water over 

stake is measured by steel scale. Discharge is computed by Francis formula.

REGULATION. Flow regulated by series of three reservoirs having an aggregate capacity of 1,400 acre-feet; reservoirs operated by Colorado Springs water department.

DIVERSIONS. Water diverted above weir for use in Victor is measured and added 

to flow over Boehmer Creek weir to show total run-off.

COOPERATION. Monthly discharge computed from records furnished by Colorado 

Springs water department.

36 SURFACE WATER SUPPLY, 1019-1920, PART VII.

SOUTH RTTXTON CREEK AT HALFWAY, COLO.

LOCATION. In SW. sec. 11, T. 14 S., R. 68 W., just above hydroelectric intake at 

Halfway, El Paso County. No tributary between station and mouth, a short 

distance below. South Ruxton Creek enters Ruxton Creek from south at Halfway. Elevation of station, 9,000 feet.

DRAINAGE AREA. 3.95 square miles (measured on topographic map). Practically 

all below timber line and heavily timbered.

RECORDS AVAILABLE. June 1, 1908, to September 30, 1920. ,

DETERMINATION OP DISCHARGE. Flow measured by two sharp-crested weirs, with 

complete end contraction. Discharge is computed by Francis formula. The 

main weir is one-third mile above mouth of creek and a short distance above 

hydroelectric intake which has a capacity of 4.83 second-feet. The second weir 

is half way between main weir and mouth of the creek and measures the inflow 

chiefly from springs below intake and a small amount of seepage. At all times 

except during high water, the capacity of intake is sufficient to take entire flow 

passing main weir, and flow at the two weirs is combined to give the total run-off 

from the basin. During high water the excess passing intake and recorded at 

lower weir does not represent increased flow between weirs, and is discarded. 

In its place is used a constant quantity based on inflow and seepage at other times.

DIVERSIONS. None.

REGULATION . None.

COOPERATION. Monthly discharge computed from records furnished by Colorado 

Springs water department.

Monthly discharge of South Ruxton Creek at Halfway, Colo., for the years ending Sept.

CABIN CREEK NEAR HALFWAY, COLO.

LOCATION. In SW. i NW. \ sec. 11, T. 14 S., B. 68 W., just above hydroelectric 

intake, about three-eighths mile north of Halfway, El Paso County. Cabin 

Creek enters Buxton Creek half a mile below Halfway. Elevation of station, 

about 9,000 feet.

DRAINAGE AREA. 2.4 square miles (measured on topographic map). About 15 per 

cent of area above timber line; remainder sparsely timbered.

BECORDS AVAILABLE. October 1, 1906, to September 30, 1920.

DETERMINATION OF DISCHARGE. Flow measured by two sharp-crested weirs with 

complete end contraction. Discharge computed by Francis formula. The main 

weir is about one-third of a mile above mouth of creek and just above the hydroelectric intake. The second weir is 50 feet above mouth of creek and measures 

flow from springs and small tributaries entering below intake. Except during 

high water the measured flow at weirs is combined to give total run-off from basin. 

During high water, record from the lower weir is discarded and inflow estimated.

NEOSHO RIVER NEAR IOLA, KANS.

LOCATION. In NE. J sec. 9, T. 25 S., R. 18 E., 2J miles south and H miles west of 

Tola, Alien County. Elm Creek enters from east 1 mile upstream, and Owl 

Creek enters from west 8 miles downstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 12, 1917, to September 30, 1920. August 1, 1895, to 

November 30, 1903, a gaging station was maintained about 4 miles upstream, 1 

mile west of lola, at city water and power house dam. The United States 

Weather Bureau staff gage is a short distance upstream from this dam.

GAGE. Stevens continuous water-stage recorder on left bank. Staff gage at this 

location is in two sections; lower inclined, upper vertical and fastened to downstream side of concrete gage well. During periods when recorder was not operating 

satisfactorily staff gage was read by Ruth Conger until March 14, 1920, and by 

Esther Teats thereafter.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading above pipe-line 

ford about three-fourths of a mile downstream from gage.

CHANNEL AND CONTROL. Control is long shale riffle, half a mile downstream from 

gage, terminating at pipe-line ford, where a 16-inch gas pipe line, anchored by 

concrete blocks in channel, crosses the stream bed; probably permanent. At low 

water, pooled section at gage. Bed composed of gravel. Left bank is high and 

well-defined ledge of limestone confines the flood channel on the left bank near 

the gage. Right bank is lower but is overflowed only for about three fourths of 

a mile at extreme high stages. On account of the high banks this section of the 

river is less subject to overflow than elsewhere along the Neosho Valley, in this 

vicinity. Channel is straight for a long distance upstream and bends slightly 

downstream from gage.

EXTREMES or DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 19.4 feet at 4 a. m. March 21 (discharge, 23,700 second-feet); minimum 

stage, 2.55 feet, October 3 to 5 (discharge, 8 second-feet).

Maximum stage recorded during year ending September 30, 1920, 13.1 feet at 

11 a. m. September 9 (discharge, 11,300 second-feet); minimum stage 1.9 feet June 

23 (discharge, 1 second-foot).

1917-1920: Maximum stage recorded, same as given above for March 21, 1919; 

minimum stage that of June 23, 1920.

1895-1903: United States Geological Survey record: Maximum stage recorded, 

22.0 feet, June 3, 1904 (discharge, 39,100 second-feet); higher discharge given 

for 20.1 feet, May 24, 1896 (discharge, 45,600 second-feet). 1904: Maximum 

stage, 24.0 feet, July 10, 1904, determined from high-water marks (discharge, 

estimated as 74,600 second-feet). Minimum discharge, *zero, several days in 

September and October, 1897.

ICE. Stage-discharge relation affected by ice; flow estimated from observer's notes, 

and records of precipitation and temperature. No winter discharge measurements made.

DIVERSIONS. Water is taken from river by cities upstream for domestic water suppiyREGULATION. Low-water flow is regulated by dams upstream.
ARKANSAS RIVER BASIN. 41

ACCURACY. Stage-discharge relation fairly permanent. Rating curve, used October 1, 1918, to May 20, 1919, well denned below 10,000 second-feet; extended 

to cover high stages by area-velocity curve study; curve used May 21, 1919 to 

September 30, 1920, well denned between 40 and 10,000 second-feet. Waterstage recorder checked weekly by observer's reading of outside staff gage to 

quarter-tenths. No record from water-stage recorder: October 6-12, 23-25, 30, 

November 8-14, 1918, October 25, 26, October 31 to November 12, December 

9-12, 1919, March 7-14, June 7-9, July 16, July 29 to August 4, 1920; approximate gage heights for purposes of estimating discharge were determined from 

gage relation between United States Weather Bureau gage above dam at lola 

(see "Location," "Records available") and United States Geological Survey 

water-stage recorder, using United States Weather Bureau gage record. March 

26 to August 1, 1919, intake pipe was partially clogged and recorder was not 

always recording same as outside staff gage. During this period observer made 

daily readings on staff gage which enabled the graph to be corrected to outside 

gage datum. Well and intake were cleaned, August 2, 1919. March 30, 1920, 

recorder started to read higher than outside gage; intake and well partially 

clogged. This condition occurred irregularly with the stage of the river. August

29. 1920, the well was cleaned out thoroughly, but a rapid rise in river prevented 

cleaning intake pipe until October 1, 1920. During these periods observer made 

some extra readings and graph was corrected to outside^gage datum. Daily discharge ascertained by applying mean daily gage height to rating table, except 

for periods, December 29, 1918, to January 18, 1919, and December 12-28, 1919, 

when stage-discharge relation was affected by ice; flow estimated for these periods 

from observer's notes and records of precipitation and temperature. Records 

good for low and medium stages, fair for high stages on account of intake clogging 

and uncertainty in gage record during these periods, for year ending September

30. 1919; good for year ending September 30, 1920.
