SURFACE WATER SUPPLY OF THE LOWER MISSISSIPPI RIVER BASIN, 1918.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1918.

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 examination 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 reports upon the best methods of utilizing the water 

" resources.

Awniial appropriations for the fiscal yea-rs ending June SO, 1895-1918.

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 9.

Measurements of stream flow have been made at about 4,510 points 

in the United States and also at many points in Alaska and the 

Hawaiian Islands. In July, 1918, 1,180 gaging stations were being

maintained by the Survey and the cooperating organizations. Many 

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 depth in inches, acre-feet, and millions of 

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

second-feet, second-feet per square 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 fundamental 

unit from which others are computed.

" 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.

"Eun-off (depth in inches)" is the depth to which an area would 

be covered if all the water flowing from it in a given period were uniformly distributed on the surface. It is used 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 terjm used to designate the section or sections of the 

stream channel below the gage which determine 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 u point of zero flow " for a given gaging station is that point 

on the gage the gage height to which the surface of the river falls 

when the discharge is reduced to zero.

EXPI^ANATION OF DATA.

The data presented in this report cover the year beginning October 

1,1917, and ending September 30,1918. 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 runoff 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
8 SURFACE WATER SUPPLY, 1918, PART VII.

mean 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 opef ating 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 meaii 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 cohlmn 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 6, are based.

ACCURACY OF FIELD DATA AND COMPUTED RECORDS.

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 (depth in inches)" are therefore not computed if such errors 

appear probable. The computations are also omitted for stations 

on streams draining areas in which the annual rainfall is less than 20
ACCURACY OF DATA AND RECOEDS. 9

inches. All figures representing " second-feet per square mile " and 

"run-off (depth in inches)" previously published by the Survey 

should be used with caution because of possible inherent sources of 

error not known to the Survey.

The tables of monthly discharge give 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 service of a hydrographer during the 

winter.

The United States Reclamation Service paid for the maintenance 

of the stations on Medicine Bluff Creek and Little Medicine Bluff 

Creek near Lawton and the evaporation station in Lawton reservoir, Okla.

In Kansas the work was done in cooperation with the Kansas 

Water Commission, H. A. Rice,-secretary, under terms of the watercommission act of the legislature of 1917 (Session laws of Kansas, 

1917, chap. 172, p. 218), authorizing an investigation of the water 

resources of Kansas. The cooperative agreement with the commission was made May 11, 1917, and district headquarters were established June 1, 1917, in the Federal Building, Topeka.

DIVISION OF WORK.

Data for stations in Colorado and Oklahoma were collected and 

prepared for publication under the direction of Robert Follansbee, 

assisted by S. B. Soule, H. W. Fear, T. J: Watkins, P. V. Hodges. 

J. B. Spiegel, and Miss E. M. Dye.

Data for stations in Kansas were collected and prepared for publication by Roger C. Rice, district engineer, assisted by E. L. Grant 

and A. K. Gowans.

GAGING-STATION RECORDS.

ARKANSAS RIVER BASIN. 

EAST FORK OF ARKANSAS RIVER NEAR LEADVILLE, COLO.

LOCATION. In sec. 16, T. 9 S., R. 80 W., at highway bridge 200 yards above 

mouth of Tennessee Fork, 3 miles northwest of Leadville; Lake County.

DEAINAGE AEEA. 52 square miles (measured on topographic map).

UECOBDS AVAILABLE. April 25 to August 31, 1890; June 18 to October 11, 

1903; June 5, 1911, to September 30, 1918.
10 SURFACE WATER SUPPLY, 1918, PART VII.

GAGE. Vertical staff on left bridge abutment, near upstream end; read by 

Fred Coquoz. No known relation between present gage and gages used 

prior to 1911.

DISCHABGE MEASUREMENTS. Made from bridge or by -wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel and small boulders. 

Control 30 feet downstream from gage; practically permanent during 1918. 

Banks low, subject to overflow at extreme high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.95 feet at 

8 a. m. June 12 (discharge, 680 second-feet) ; minimum discharge probably occurred during winter.

ICE. Stage-discharge relation seriously affected by ice; observations discontinued during winter.

DIVERSIONS. The Leadville Water Co. makes a continuous diversion of 2 

second-feet from the East Fork above the station. During winter this 

diversion may be increased to 3 second-feet.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent, except as affected by ice. 

Rating curve well defined below 300 second-feet. Gage read to hundredths 

twice daily. Owing to high altitude of drainage area (9,700 feet), alternate melting and freezing during certain seasons causes considerable 

diurnal fluctuation, and 'mean daily gage heights based on morning and 

evening readings may be somewhat in error. Daily discharge ascertained 

by applying mean daily gage height to rating table. Records good.

TENNESSEE FORK NEAR LEADVIIXE, COLO.

LOCATION. In sec. 16, T. 9 S., R. 80 W., at highway bridge a few hundred 

yards above mouth of stream and 3 miles northwest of Leadville, Lake 

County.

DRAINAGE AREA. 45 square miles (measured on topographic map).

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

February 8, 1911, to September 30, 1918.

GAGE. Vertical staff on downstream side of left bridge abutment; datum lowered 0.40 foot October 6, 1914; read by Fred Coquoz. No known relation 

between present gage and gages used in 1890 and 1903.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

at rapids a short distance below gage; practically permanent. Banks subject to overflow during extremely high wate»r.

EXTREMES or DISCHARGE. Maximum stage recorded during year, 2.05 feet at 8 

a. m. June 14 (discharge, 450 second-feet) ; minimum stage, 0.10 foot during 

latter part of October and first of November (discharge, 1 second-foot).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. There are court decrees for diversions of 24 second-feet above 

station; also for diversion of 18.5 second-feet from the basin of Eagle River 

through Ewing ditch to basin of Tennessee Fork above station. During 

1918, 2,210 acre-feet were diverted from Eagle River basin.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent except as affected by ice. Rating curve well defined between 10 and 240 second-feet. Gage read to hundredths twice daily. Owing to high altitude of drainage basin (9,700 feet) 4 

alternate melting and freezing at certain seasons causes considerable diurnal 

fluctuation, and mean daily gage heights based on morning and evening 

readings may be somewhat in error. Daily discharge ascertained by applying mean daily gage height to rating table. Records good.

NOTE. Discharge from November to March estimated from discharge measurements, gage heights,

COTTONWOOD CREEK BELOW HOT SPRINGS, NEAR BUENA VISTA, COLO.

LOCATION. In sec. 22, T. 14 S., R. 79 W., half a mile below old Hot Springs 

Hotel and 6 miles west of Buena Vista, Chaffee County. Nearest tributary, 

South Fork, enters 2 miles above.

DRAINAGE AREA. 69 square miles (revised measurement on Hayden atlas).

RECORDS AVAILABLE. April 7, 1911, to September 30, 1918. From September 23, 

1910, to September 13, 1911, a station was maintained in sec. 21, a mile 

above present site. Discharge at the two sites comparable.

GAGE. Vertical staff; read by E. D. Masters. On February 19, 1915, gage was 

moved from side of left abutment to downstream end and reset to same 

datum. In present position water does not pile up on gage, especially during high water, and therefore for same discharge gage height will be less.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

distance below gage; shifted during 1918. Banks high; probably not 

subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2 feet at 6 a. m. 

June 9 and 10 (discharge, 467 second-feet) ; minimum stage recorded, 0.35 

foot at 7 a. m. March 23 (discharge, 12 second-feet). 

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

DIVERSIONS. There are court decrees for diversions of 148 second-feet from Cottonwood Creek, of which 28 second-feet are above gaging station.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent; shifting during high water. 

Rating curve used October 1 to June 5 fairly well denned between 20 and 

350 second-feet; curve used June 25 to September 30 well defined between 

40 and 250 second-feet. Gage read to hundredths twice daily. Owing to 

high altitude of drainage area, alternate melting and freezing at certain 

seasons causes considerable diurnal fluctuation, and mean daily gage heights 

based on morning and evening readings may be somewhat in error. Daily 

discharge ascertained by applying mean daily gage height to rating table; 

shifting-control method used June 6-24. Records good except during high 

water, for which they are fair.

WEST BEAVER CREEK NEAR VICTOR, COLO.

LOCATION. In sec. 30, T. 16 S., R. 68 WM Fremont County, at Skaguay power 

station of Arkansas Valley Railway, Light & Power Co., 7 miles southeast 

of Victor.

DRAINAGE AREA. 70 square miles.

RECORDS AVAILABLE. January 1, 1905, to September 30, 1918.

DETERMINATION- OF DISCHARGE, Water used through power house is brought 

by pipe line from reservoir 3| miles upstream; quantity measured hourly 

by weir, and a quantity representing the gain or loss in tfie 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 into Lake Moraine, and thence 

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

supply. Filings on these diversions from the basin 52 second-feet by 

ditch and 5 second-feet by pipe line have riot yet beeji adjudicated. 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., and are probably correct within 5 per cent.

DBAINAGE ABEA. 7.2 square miles (measured on topographic map). About 75 

per cent of this area is ahove timber line. To the natural drainage has 

been added that of West Beaver Creek above Strickler tunnel intake.

RECORDS AVAILABLE. October 1, 1909, to September 30, 1918.

DETEBMINATION or DISCHABGE. 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.

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

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

COOPEBATION. Monthly discharge computed from records furnished by Colorado Springs water department.

SOUTH EUXTON CHEEK Al HALFWAY, COLO.

LOCATION. In SW. J 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 the 

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, 1906, to September 30, 1918.

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

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

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

above the hydroelectric intake, which has a capacity of 4.63 second-feet. 

The second weir is halfway between main weir and mouth of creek and 

measures the inflow chiefly from springs below the intake and a small 

amount of seepage. At all times, except during high water, the capacity of 

the intake is sufficient to take the entire flow passing main weir, and flow at 

the two weirs is combined to give total run-off from the basin. During 

high water the excess passing the intake and recorded at the lower weir 

does not represent increased flow between the weirs, and is discarded. In 

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

times.

per cent of area above timber line; remainder sparsely timbered.

RECORDS AVAILABLE. October 1, 1906, to September 30, 1918.

DETKRMINATION 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 the flow from springs and small tributaries entering below 

the intake. Except during high water measured flow at the weirs is combined to give total run-off from the basin. During high water the record 

from lower weir is discarded and the inflow estimated. (See description 

of South Ruxton Creek at Halfway, Colo.)

DIVERSIONS. None.

REGULATION. None.

COOPERATION. Monthly discharge computed from records furnished by Colorado 

Springs water department.

NEOSHO RIVER NEAR IOLA, KANS.

LOCATION. In NE. 1 sec. 9. T. 25 S., R. 18 E , 3 miles southwest of lola, Alien 

County. Elm Creek enters from oast 1 mile upstream, and. Owl Creek 

enters from west 8 miles downstream.

DRAINAGE AEEA. Not measured.

RECORDS AVAILABLE. October 12, 1917, to September 30, 1918. The gaging 

station was formerly maintained about 4 miles upstream, 1 mile west of 

lola, at city water and power-house dam for period August 1, 1895, to 

November 30, 1903. The United States Weather Bureau staff gage is 

a short distance upstream from this dam.

GAGE. Stevens 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. Staff gage was read daily by observer, 

Ruth Conger, during periods when recorder was not operating satisfactorily.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading above Pipe 

Line ford, about three-fourths of a mile downstream from gage.
30 SURFACE WATER SUPPLY, 1918, PART VII.

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. Channel is straight for a long 

distance upstream and bends slightly downstream from gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.5 feet at 

3 p. m. June 1 (discharge, 13,800 second-feet) ; minimium stage recorded, 

2.45 feet, August 13 to 17 (discharge, 4 second-feet).

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, 1964, determined from highwater marks (discharge estimated as 74,600 second-feet). Minimum discharge, 0 second-feet, occurred on 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 purposes of 

domestic water supply.

REGULATION. Low-water flow is regulated by dams upstream.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined below 10,000 second-feet; extended to cover high-water stages by 

area-velocity curve study. Water-stage recorder checked weekly by observer reading outside staff gage to quarter-tenths. January 11-18, no gage 

record, as cog on escapement wheel of gage clock was broken. May 7-11, 

17-31, and June 1, 18-30, water-stage recorder not working satisfactorily. 

Discharge May 7-11, 21, and 29-31', determined from gage heights obtained 

by use of curve showing relation between stage at United States Weather 

Bureau gage above dam at lola (see " Location ") and United States Geological Survey water-stage recorder, using United States Weather Bureau gage 

record; May 19, 24, June 1, 24-28 and 30, determined from observer's daily 

readings of staff gage; May 17, 18, 20, 22, 23, 25-28, June 18-23 and 29, 

estimated. Daily discharge for remainder of year ascertained by applying 

mean daily gage height to rating table, except for period of ice effect, 

January 5 to February 25, for which it was estimated 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 

unsatisfactory gage record.

KED BIVEB, BASIN. 

MEDICINE BLTTFF CREEK NEAR LAWTON, OKLA.

LOCATION. In sec. 18, T. 3 N., R. 12 W., at Medicine Park, 12 miles northwest 

of Lawton, Comanche County. Nearest tributary, Little Medicine Bluff 

 Creek, enters half a mile above.

DRAINAGE AREA. About 110 square miles. ;, *

RECORDS AVAILABLE. November 26, 1912, to September 80, 1918.

GAGE. Stevens continuous water-stage recorder installed' February 16, 1915, 

on left bank one-third of a mile below Medicine Park Hotel. Original 

gage wag vertical staff on left bank a short distance below hotel, and set 

to datum 0.68 foot higher than that of present gage; fall between the two 

points, 0.18 foot. On February 19, 1917, dam was completed 200 feet 

downstream which turned a section of the creek into a pool and changed 

control completely. Datum of water-stage recorder raised. No definite 

relations between gage heights before and after completion, of dam.

DISCHAEGE MEASUREMENTS. Made from cable 100 yards above gage or by 

wading.

CHANNEL AND CONTROL. Control is crest of concrete darn.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.35 feet June 4 (discharge, 285 second-feet) ; no flow, May 27 

and 28.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Average diversions frqrn Lawton reservoir, October 1 to March 

31, 3.1 second-feet; April 1 to June 30, 3.9 second feet; July 1 to August 

31, 4.6 second-feet; September 1-30, 4.3 second-feet.

REGULATION. Flow controlled to a great extent by Lawton reservoir, which 

is 1J miles upstream; capacity 14,000 acre-feet.

NATURAL RUN-OFF. To show natural run-off of Medicine Bluff Creek, by 

months, computations have been made which include flow past gage, daily 

loss from evaporation, gain or loss by storage, and diversion for Lawton 

waterworks.

ACCURACY. Stage-discharge relation permanent. Lower part of rating curve 

based on discharge measurements; upper part on weir formula owing to 

lack of measurements. Operation of water-stage recorder not very satisfactory. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained by inspecting recorder graph, except for periods indicated in footnote to daily-discharge table. Records fair.

The following discharge measurement was made by Robert Follansbee: 

February 22, 1918: Gage height, 1.62 feet; discharge, 0.8 second-foot.
