SCOPE OP WORK

This volume is one of a series of 14 reports presenting results of measurements of stage and flow made on streams, lakes, and reservoirs in the United States during the water year ending September 30, 1948. The work was begun in 1888 in connection with special studies relating to irrigation. Measurements of the flow of streams and of the stage and contents of lakes and reservoirs have been made at about 11,370 gaging stations 1n the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1948, 5,960 gaging stations, including those in Hawaii, were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made during the water year at many other points. In the execution of the work many State and private organizations have cooperated, either by furnishing data or by assisting in collecting data. Cooperation of the first kind is acknowledged in connection with the description of each station affected; cooper­ ation of the second kind-is acKnowledgea, under the heading "Cooperation," in the intro­ ductory matter that precedes the gaging-station records In each volume. In trie present volunie, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used nerein are defined as follows: "Second-feet" is an abbreviation for "cubic feet per second." A second-foot is t.. - rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and whose average velocity is 1 foot per second. "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 runoff is dis­ tributed uniformly both as regards time and area. "Runoff in inches" is the depth to which an area woulu be covered if all the water draining from it in a given period were uniformly distributed on its surface. It is used, for comparing runoff with rainfall, which is usually expressed in inches. An "acre-foot" is the quantity of water required to cover an acre to the depth of 1 foot and Is equivalent to 43,560 cubic feet. The term is commonly used in connection with storage for irrigation. "Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and represents a runoff of 0.0372 inch from 1 square mile. "Stage-discharge relation" is an abbreviation for the term "relation between gage height and discharge." "Control" is a term used to designate a feature downstream from me gage that deter­ mines the Stage-discharge relation at the gage. This feature may be a natural section, a reach of the channel, or an artificial structure. 1 2 SURFACE WATER SUPPLY. 1948, PART 7

"Contents" is a term applied to the volume of water in a reservoir. It is computed on .the basis of a level pool and does not include bank storage unless otherwise indicated.

EXPLANATION OP DATA

The base data collected at gaging stations consist of records of stage, measurements of discharge, and general information used to supplement the records of stage and discharge measurements in determining the daily flow. The records of stage are obtained either from direct readings on a nonrecordlng gage or from a water-stage recorder that gives a con­ tinuous record of the fluctuations. Measurements of discharge are made with a current meter by the general methods outlined in standard textbooks on the measurement of river discharge. Typical structures in use at gaging stations are shown in figure 1. Rating tables giving the discharge for any stage are prepared from the discharge meas­ urements. The application of the daily mean gage height to those rating tables gives the dally mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation is -subject to change because of frequent or continual change in the physical features that form the control, the daily mean discharge is de­ termined by the "shifting-control method," in which correction factors based on individ­ ual discharge measurements and notes by engineers and observers are used in applying the gage heights to the rating tables At times the stage-discharge relation for a station may be temporarily changed by the presence of aquatic growth or debris on the control. For such times the daily mean discharge is computed by what is essentially the "shiftingr control" method, described above. At some gaging stations the stage-discharge relation is affected by backwater from reservoirs, tributary streams, or other sources, which necessitates the use of the "slope method," in which the slope or fall in a reach of the stream is a factor in the determi­ nation of discharge. Information requisite for determining the slope or fall is obtained by means of an auxiliary gage set at some distance from the base gage. At some stations the stage-discharge relation is affected by changing stage, and for them the rate of change of stage is used as a factor in the determination of discharge. At most gaging stations in the northern part of the United States and at some in the mountainous regions of other parts the stage-discharge relation is affected by ice during the winter, which makes it' impossible to compute the discharge in the usual manner. Dis­ charge for periods of ice effect is computed on the basis of the gage-height record -and occasional winter discharge measurements, consideration being given to the available in­ formation on temperature and precipitation, notes by gage observers and engineers, and comparable records of discharge for stations in the same or nearby basins. For those stations at which the stage-discharge relation is affected by ice, the days included in the periods of ice effect either are indicated in the table by symbols referring to a footnote that states this fact or are given in a general note following the table. The days on which discharge measurements were made during or between periods of ice effect, shortly before the first period, or shortly after the last period are similarly Indicated by a footnote. For moat of the gaging stations on streams in the. area covered by this report the data presented comprise a description of the station, a table showing the daily discharge of A.

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating tables are published for all stations except those at which the daily discharge for the greater part of the year was determined by the shifting-control method, the slope method, or other special methods. The description of the station gives the type of gage, location, drainage area, records available, average discharge, extremes of discharge, general remarks, and notations of re­ visions of previously published record. The location of the gaging station and the drain­ age area are obtained from the most accurate maps available. Under "Average discharge" is given the average discharge for the number of years indicated. It is not given for sta­ tions having .less than 10 complete years of record or for stations where changes In water development during the period of record cause the figure to have little significance. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge If there is little or no "regulation; the minimum daily discharge if there is extensive regu­ lation (also the minimum discharge if useful); and. the minimum gage height (unless it is of no importance). Unless otherwise qualified, the maximum discharge corresponds to the crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the time of the crest. Information pertaining to the accuracy of the records and conditions which affect the natural flow at the gaging station Is given under "Remarks." For some stations previously published records have been found to be in error on the basis of data or information obtained subsequently. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it easier to find such revised records, a paragraph headed "Revisions (water years)" has been added to the station description of all stations for which revised records have been published. Listed therein are all the reports in which revisions appear, each followed by the water years for which figures are revised in that report. In listing the report number, W. means Water-Supply Paper. In listing the years, water years are indicated by only 1 year, for instance, 1933 stands for the water year October 1, 1932, to September 30, 1933. If there were no daily, monthly, or annual figures of discharge Involved in the revision, that fact is brought out by notations after the year dates as follows: (M) means that only the instantaneous maximum discharge was revised; (m) that only the instantaneous minimum was revised: and (P) that only peak discharges were revised. If the drainage area has been revised, the report in which the revised figure was first published is given. It should be noted that for all stations for which second-feet per square mile and runoff in inches are published, a revision of the drainage area necessitates corresponding revision of all figures based on the drainage area. Revised figures of second-feet per square mile and runoff in inches resulting from a revision of the drainage area only are usually not published in the annual series of reports. For stations equipped with water-stage recorders, except those on streams subject to sudden or rapid fluctuation, the table gives the discharge corresponding to the dally mean gage height. For stations subject to such fluctuation the daily mean'gage height may not indicate the true daily mean discharge, which must be obtained by averaging the discharge for parts of the day or by using the discharge integrator, an instrument for obtaining the daily mean discharge from a continuous gage-height graph and containing as an essential element a curve representing the stage-discharge relation at the station. For stations equipped with nonrecording gages, the table of daily discharge gives the discharge ACCURACY OF FIELD DATA AND COMPUTED RESULTS 5 corresponding to either once-daily readings of the gage, the mean of twice-daily readings, or the mean gage .height determined from gage-height graphs based on gage readings. For periods of rapidly changing stage, the daily mean discharge is determined from gage-height graphs based on gage readings, the frequency of which is stated in the station description. In the table of monthly discharge the column headed "Second-foot-days" gives the sum for each month of the figures given in the table of daily discharge. The column headed "Maximum" gives the maximum daily discharge, not the momentary discharge when the water surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic feet per second during the month. Peak discharges with the times of their occurrence are listed below the table of monthly discharge for most stations. All independent peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. Peak discharges are not published for canals, ditches, drains, or for any stream for which the peaks are subject to substantial control by man. For most gaging stations on lakes and reservoirs the data presented comprise a descrip­ tion of the station and a monthly summary table of stage and contents. For some reser­ voirs a table shoeing daily contents or stage is given. A skeleton table of capacity at given stages is usually given in the first report in which data for a station are published but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stage- discharge relation or, if the control is unstable, the frequency of discharge measurements and (2) the accuracy of observations of stage, measurements of flow, and interpretation of records. The station description gives a statement in regard to the general accuracy of the rec­ ords. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than IS percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean discharge and runoff are, in general, more accurate than the daily records. Yield at some stations as indicated by monthly means may vary widely from natural yield, owing to diversion, consumption, regulation by storage, increase or decrease in evaporation due to artificial causes, or other factors. For such stations figures of "second-feet per square mile" and "runoff in inches" are not published unless 'storage or diversion records are included indicating the extent of the regulation or diversion or unless satisfactory adjustments can be made for changes in contents or reservoirs or for other1 changes incident to use and control. Evaporation from a reservoir is not Included in the adjustments for changes in reaervoir contents, unless its inclusion is indicated. Even at those stations where adjustments are made, in some instances large errors in computed yields may occur when relatively large negative adjustments are applied or when evaporation is large in comparison with the observed discharge. Figures of second-feet per square mile and runoff in inches are also omitted if the drainage area includes large noncontributing areas or if the average annual rainfall over the drainage area is less than 20 inches. 6 SURFACE WATER SUPPLY, 1948, PART 7

Many gaging stations on streams In the Irrigated are.as of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded does not show the water supply available for further development, as prior appropriations below the station must first be satisfied. The table of monthly discharge presents in summary the distribution of the flow past the station. The table of daily discharge affords opportunity for more detailed studies of the variation in flow. As further observations in each succeeding year may be expected to throw new light on data previously published, it should be borne in mind that such data are subject to revision in succeeding water-supply papers.

The records at most of the stations discussed in these reports extend over a series of years. Miscellaneous measurements at many points other than regular gaging stations have been made each year and are published under "Miscellaneous discharge measurements" at the end of each report, the streams and points of measurement listed appearing in the same relative order as the streams and gaging stations in the body of the report. An index of the records obtained prior to 1904 has been published in Water-Supply Paper 119. Each of -the reports on surface water supply for the year 1939, issued as Water-Supply Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a sum-nary of yearly discharge at gaging stations at which 10 or more complete years of record have been collected. These summaries are available also as separate reprints. Reports have been published that are compilations of records for various areas, usually a single State or drainage basin. These reports contain records previously published (some of which have been revised), as well as some records not contained in the annual series of water-supply papers. The following table gives the numbers and titles of these reports, arranged alphabetically, some by States and some by drainage basins.

Little River ditch 66 near Kennett, Mo.

Location.- Wire-weight gage, lat. 36°14'10", long. 89°58'45", in NEi sec. 4, T. 18 N., R. 1U K., at bridge on State Highway 84, about 4 miles east of Kennett. Datum of gage is 241.00 feet above mean sea level, datum of 1929 (Corps of Engineers bench mark). Records available.- October 1926 to September 1948. Average discharge.- 22 years, 327 second-feet. Extremes.- Maximum discharge observed during year, 2,380 second-feet Mar. 28 (gage height, Ib.BB feet); no flow Oct. 4, 15-25, Sept. 21-29. 1926-48: Maximum discharge, 4,350 second-feet Jan. 24, 25, 1937 (gage height, 18.15 feet); no flow at times in 1944, 1945, 1947, 1948. Remarks.- Records fair except those below 20 second-feet, which are poor. Gage read once dally below 8 feet and twice daily above. An auxiliary ditch, Little River ditch 66-A (see following page), receives part of the flow through cut-offs above stage 6.4 feet. Above stage 13 feet, the low, narrow bank between the main and auxiliary ditches is submerged, and the two unite to form one stream in the vicinity of the gage. To seg­ regate the discharge of each ditch, the division line between the two is taken as the top of the bank that separates them at low stages.

RED RIVER BASIN 317

Lake Texoma near Denlson, Tex. Location.- Water-stage recorder, lat. 33°49', long. 96°34', at Denlson Dam on Red River, In NK^ sec. 33, T. 8 S., F. 7 E. Indian meridian, l£ miles upstream from Shawnee Creek, l| miles upstream from Sand Creek, and 4 miles northwest of Denison. Datum of gage is at mean sea level, datum of 1929 {levels by Corps of Engineers). Drainage area.- 38,290 square miles. Heeords available.- October 1943 to September 1948. Extremes.- Maximum contents during year, 3,261,900 acre-feet July 13 {elevation, 619.48 f'eet'J; minimum, 2.,527,600 acre-feet Nov. 14 (elevation, 611.33 feet). 1943-48: Maximum contents, 4,295,000 acre-feet Apr. 19, 1945 {elevation, 629.07 feet); minimum since power-pool stage was first reached, that of Nov. 14, 1947. Remarks.- Reservoir is formed by a rolled fill earth dam. Flow was diverted through con- duits July 27, 1942, regulated storage began Oct. 31, 1943; maximum power-pool stage was first reached Mar. 15, 1945. Capacity, 5,715,700 acre-feet at elevation 640.0 feet {crest of spillway) and 3,024,900 acre-feet at elevation 617.0 feet {maximum power pool). Dead and sediment storage, 1,211,100 acre-feet {elevation, 590.0 feet in Denison pool and 610.0 feet in Cumberland pool). When contents are below 2,400,000 acre-feet the reservoir is divided into two pools by protective levees around the Cumberland oil field on the Washita River arm with the bottom of the outlet channel for the upper pool (known as Cumberland pool) at elevation 610 feet. At higher ele­ vations the two pools are considered as being at a common level, contents being com­ puted from the gage in the Denison pool. Reservoir is used principally for flood con­ trol and power development. Figures given herein represent total contents of both pools. Cooperation.- Records furnished by Corps of Engineers.

Palo Duro Creek near Canyon, Tex.

Location.- Staff gage, lat. 35°02', long. 102°02', at conduit tower in Amarillo City Lake, 200 feet upstream from dam, 0.4 mile upstream from Nigger Arroyo Creek, 6 miles northwest of Canyon, Randall County. Datum of gage is 3,584.4 feet above mean sea level, datum of 1929. Records available.- August 1942 to September 1948 (gage heights only). Extremes.- Maximum gage height observed during year, 35.0 feet Aug. 16; lake dry most of year. 1942-48: Maximum gage height, 42.3 feet Oct. 11, 1946; lake dry at times. Highest stage known occurred June 5-7, 1937, when lake reached a stage of about 54.5 feet (spillway crest at that time, 52.5 feet gage height) according to city of Amarillo Water Department. Remarks - Lake is formed by earth-fill dam 39 feet high and 1,600 feet long with 500-foot earthern spillway crest at 50.3 feet gage height. Dam completed in February 1927. Capacity at spillway crest, about 3,200 acre-feet (estimate by city engineer of Amarillo). No water is diverted from lake. The lower part of the lake is surrounded by ten water wells which are used to partly supply city of Amarillo. The lake provides recharge to sands and gravels of underlying High Plains deposits (Ogallala formation) from which the wells draw water, in addition to the replenishment afforded by infiltra­ tion from rainfall on the surrounding area. There was no flow in Palo Duro Creek below dam during year. Field estimates of discharge of creek, in second-feet, were made 1.5 miles upstream from dam as follows:

Drainage area.- About 260 square miles, of which 200 square miles is probably noncontri- cuting. Records available.- May 1939 to June 1940 (monthly figures only). November 1940 to September 194H. Extremes.- Maximum discharge during year, 390 second-feet Aug. 3; maximum gage height not determined, probably occurred during period of no record Oct. 1-7; no flow at times. 1939-48; Maximum discharge, 3,110 second-feet Oct. 4, 1941; maximum gage height, 95.48 feet Oct. 4, 1941; no flow at times during-most years. Remarks.- Records poor. Records given herein represent flow into reservoir. Discharge Delow gage height 91.9 feet (spillway crest) determined from daily change in contents of reservoir; that above gage height 91.9 feet determined by algebraic summation of flow over spillway (computed from spillway rating curve), compute! flow through con­ duit, and change in contents of reservoir (computed from capacity curve and reduced to equivalent second-feet). No adjustment made for evaporation or seepage losses. Small springs flowing into creek above reservoir are measured occasionally and discharges when inflow was less than reservoir losses were estimated on basis of these measure­ ments. Dam completed Jan. 15-, 1939. Reservoir capacity, 654 acre-feet. Reservoir used for recreational purposes and water is rarely released through outlet gate, but flow of a spring discharging just below reservoir was estimated as follows: Discharge Date Discharge Date (second-foot) (second-foot) Oct. 22 0.07 May IB 0.01 Dec . 8 .07 June 17 .05 Jan. 21 .08 July 16 .01 Mar. 1 .07 Aug. 9 .08.

Atchafalaya River at Krotz Springs, La.

Location.- Water-stage recorder, lat. 30°32'48", long. 91°45'04", in sec. 7, T. 6 S., R. '/ hi. Louisiana meridian, at bridge on U. S. Highway 190, half a mile north of town of Krotz Springs, 0.6 mile upstream from New Orleans, Texas & Mexico Railway bridge,, 10 miles upstream from Bayou Courtableau, and 42 miles downstream from confluence of Red River and Old River (head of Atchafalaya River). Datum of gage is at mean Gulf level, datum of Corps of Engineers, and 0.03 foot below mean sea level, datum of 1929, supple­ mentary adjustment of 1941 (levels by Corps of Engineers). Records available.- October ±934 to September 1948. Gage-height records collected since layy at railroad bridgs 0.6 mile downstream are contained in reports of Mississippi River Commission; records prior to that date on file in office of Missouri Pacific Railroad Co. Average discharge.- 14 years, 154,500 second-feet. Extremes.- Maximum discharge during year, 423,000 second-feet Apr. 26 (gage height, 32.1 feet In gage well, 33.2 feet from outside gage); minimum, 41,600 second-feet Oct. 27 (gage height, 5.9 feet). 1934-48: Maximum discharge, 575,000 second-feet Apr. 29 to May 2, 1945 (gage height, 37.5 feet in gage well, 39.1 feet from outside gage, on Apr. 29); maximum gage height recorded, 37.80 feet in gage well Feb. 28, 1937; minimum discharge, 17,400 second-feet Nov. 4, 1939; minimum gage height, 2.28 feet Nov. 5, 1939. Prom information by Louisiana State Department of Highways, flood of May 1927 reached a stage 0.2 foot lower than that of April and May 1945. Remarks.- Records excellent. Flow is from entire Red River Basin except for natural di- version through Old River either from or into Mississippi River. The gage heights tabulated telow indicate elevations in the gage well. Due to draw-down around the pier in which the well is located, the water surface in the well is sometimes lower than that near the middle of the river. There is practically no difference below a gage height of 8.0 feet while at 26.0 feet it is 0.5 foot lower in the well and at 37.0 feet it is 1.5 feet lower.
