( -, SCOPE OF WORK . ' , ^ > (
This volume- is one of A series of 14 reports presenting result? of measurements -of stage and flow made on streams, lakes, and reservoirs in the united states during -the ' water year ending September '30, 1944. The work was begun In ISB&'in eonriestlon with ' special studies relating to irrigation. Measurements of tfe flour of streams and-of the ,stage and contents of lakes and reservoirs have been made at about 10,000 gaging stations in the 48 states end also at many In the Territories of Alaska and Hawaii. In July 1944, 6,340^ gaging stations, including those in Hawaii, were being maljrrtalned by the (jeologlcal Survey and cooperating organisations. Miscellaneous discharge measurements wera made . daring the water year at many other points. In the execution of the work many State and private organisations'have-cooperated, either by furnishing data or fty assisting In collecting data.' Cooperation of the.ftrst kind Is acknowledged in connection with' the description of each station affected;' cooper ation of the second kind is acknowledged, under the heading "Cooperation," in the intro ductory matter that precedes tfee gaglng-statlon records In* eaoih volume; In the present volutte, ttje section 09 cooperation of the second kind appears on-page 1st
* , . DEFINITieN OF TEFaiS , ' " \ ' ,; The units in, which stream-flow data are presented in this report and other 'terms used ' herein are defined as follows: . ' ' ,' "Second-feet" Is an abbreviation for "cubic feet per second," A second-foot5 IS the ratal of discharge of a stream whose channel is 1 square foot la cross-sectional'area and. whose average velocity is l*foot per second. . "Second-feet per pquare mile" is the average number of .cubic feet of water flowing per second from each square mile of area drained, on the assumpti-oa that the runoff 1? dis tributed uniformly-both as regards'time and area. ' ( - t . *$unoff in Inches" is the' depth te which .an area would be eoverea 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 "aera-foot* is the quantity of water required to eov.er aa acre to'law-depth of 1 foot and Is equivalent to 43,660 cubic feet. The term Is commonly used in connection , with storage, for irrigation, . '., / > ' "Second-foot-daiy" is «»e voluos at water represented by a flow of '1 second-foot fop St hours. It ia equivalent to 86,400 cubic feet,-1.983471 aore-feat, 01- 646,317 gallons and Represents a runoff of 0,og72 inch from 1 square »iie» - . - . *Stag«-d^charg» relsttoft* Is an abbreviation for the tern "relation between gage height an0 discharge." - J "Control* is a term used to designate a feature downstream front the gage that determines the stage-discharge relation at the sage. This feature my be a,natural section, a reach of» the channel, or an artificial .structure, ' , , 2 ' SURFACE MATES SUPPLY, 1944, PART 11
"Contents" Is a term applied to the volume of water in a reservoir, not including water In bank storage unless so indicated. ^
EXPLANATION OF DATA The base data collected afr gaging stations consist of .records of state, measurements of discharge, and general Information used to supplement the records of stage atid discharge measurements in determining the daily flow. The records,of stagf are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a 'con tinuous record of the fluctuations. Measurements of discharge are aade with.a current meter'by the general methods outlined In standard'textbooks on the measuremejn^ 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 dally mean gage height to those rating tables gives the daily 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 tWe 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 daUy warn discharge is computed by what is essentially ti» *nhlfting- 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, de-terffll- natlon of discharge. Information requisite fgr determining the slope or fall'is obtained by means 'of an auxiliary .gage set at some dlstancs from the base gage. At some stations 1 i. the stage-discharge relation is affected by changing stage, and from them the rate of change of'stage is used as. a factor vln the determination of discharge. At most gaging stations In the northern,part of- the United States and at BOOB 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 "uBual manner. Dis charge for perlode of Ice effect Is computed on the basis of the gage-height record and occasional winter discharge measurements, consideration being given te-the a'val-lable in-' ' formation-on temperature and precipitation, notes by gage observers^ and engineers, and comparable records of discharge for stations i« the same or nearby baeltis. for those stations at which the stafee-dlscharge relatlon'ls affected by Ice, the days incl-dded In' - the periods1 of. Ice% effect either are Indicated in the table by symbols referring\ to a footnote that states ttiis fact or are given .In a general note following the table. The days on which discharge measurements were made during or between periods of Itfe effect,- shortly before the first period, or shortly after the last period "are similarly indicated by a footnote. , For most 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 dally discharge 6f the stream, and a table of monthly and yearly discharge and runoff.

tables are published for all stations except those at which the dally 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, Its latitude and longitude as determined from the best available maps, and Information In regard to diversions that decrease the flow at the gage, artificial regulation from pondage or storage, and the accuracy of the records. Under "Average discharge" Is given the average discharge for the number of years Indicated. It Is given only for stations for which there are 10 or more complete years of record. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if there Is little or no regulation; the minimum dally discharge If there Is extensive regulation (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 nonrecord- Ing gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified, selected peak discharges with the times of their occurrence are given, below the table of monthly discharge, for some stations. This supplementary Information Is generally omitted for a station at which the drainage area of the stream Is less ttian 10 or more tJvan 10,000 square miles or at which, on most days, the peak discharge exceeds the mean discharge by less than 10 percent. 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 dally mean gage height may not Indicate the true dally mean discharge, which must be obtained by averaging the discharge for parts of the day or by using the dlschargs Integrator, an Instrument for obtaining the dally 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 nonrecordlng gages, the table of dally discharge gives the discharge In second-feet corresponding to once-daily readings of the gage or the mean of twice-daily readings. For periods of rapidly changing stage the dally mean discharge Is determined from gage-height graphs based on gage readings made once or twice dally or oftener, as stated In the station description. In the table of monthly discharge ttie column headed "Second-foot-days" gives the sum for each month of the figures given In the table of dally discharge. The column headed "Maximum" gives ttie maximum dally 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 dally discharge. The column headed "Mean", gives the average flow In cubic feet per second during the month. 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 reservoirs a table showing dally contents 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.

~" , * TIMB BASIS ' M it 2 a.m. on February 9, 1948, jts an emergency measure, tJ»e Katlon shifted front ; standard time to 'war time," and clock time in the several aonee of the country was sored ahead 1 hour, or to 8 a.m. Records of daily discharge prior to February 9, 194®, were ' , , - > computed on the basis of standard time.. Records subsequent to that date have be* computed on the basis of war time. To convert war tine to standard time, subtract 1 hour.
' _ 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 t and (2) $he accuracy of observations of stage, measurements of flow, and interpretation of records. , i . ' ' The station description gives a statement in regard to the .general accuracy of the records. "Excellent" indicates that, in general, the error in'the daily records ls/ , believed to be less than 5 percent; "good," less than 10 percent; "fair," lass than IS per cent; and "poor," {probably more than 15 percent. The records of monthly and yearly mean ' discharge and runoff are, In.general, more accurate than the dally records. Tleld at some stations as indicated by monthly means nay vary widely from natural yield, *v \ * 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 / i \ 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 other changes incident to use and control. Evaporation from a reservoir Is not included in the adjustments for changes in reservoir contents, unless its Inclusion Is indicated. Figures of second-feet per square mile and runoff in inches are also omitted if the drainage* area Includes large nonconjjfibutlng areas or If the average amual rainfall over the drainage, area is less than 80 inches. Many gaging stations on streams In the irrigated areas, of the united States are situ- ated above most of the diversions from those streams, and therefore the discharge recorded does not show the- water supply available for furthej* 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 dally discharge affords opportunity for more detailed studies of the variation In flow. As'further observations In each succeeding year,ma> be expected to ttirow new light on data previously published, it should be borne in mind that such data are subject to revision in succeeding water-supply papers.
