DRAINAGE AREA - 2,600 mi².
REVISIONS HISTORY - WSP 1314: 1923 (M). WSP 1634: 1904.
SURFACE-WATER RECORDS
PERIOD OF RECORD - Jul. 1902 to Dec. 1904, Jan. 1905 to Jul. 1908 (fragmentary), Jan. 1920 to Sep. 1924, Mar. 1925 to Sep. 1935, Jan. 1939 to current year. Monthly discharge only for some periods published in WSP 1734.
GAGE - Water-stage recorder. Elevation of gage is 4,300 ft above National Geodetic Vertical Datum of 1929, from topographic map. Jul. 22, 1902, to Jul. 31, 1908, nonrecording gage at site 2.5 mi upstream at different datum. Jan. 15, 1920, to Sep. 30, 1929, nonrecording gage or water-stage recorder at several sites near present site at various datums; Oct. 1, 1929, to Sep. 30, 1935, water-stage recorder at site 1.5 mi downstream at different datum. Jan. 1939 to Sep. 1958, non-recording gage on bridge 300 ft downstream at datum 1.19 ft higher.
COOPERATION - Records for Jan. 1939 to Sep. 1958 were provided by Walker River Irrigation District. 
REMARKS - Many diversions for irrigation above station. Flow regulated by Bridgeport Reservoir (station 10292500) and Topaz Lake (station 10297000), combined capacity, 101,900 acre-ft. No flow at times in 1924, 1925, 1931 and 2014.  10/01/2013-09/30/2014: Records fair except for estimated daily discharges, which are poor. 10/01/2014-09/30/2015: Records fair. 10/01/2015-09/30/2016: Records fair except for estimated daily discharges, which are poor.  10/01/2016-09/30/2017: Records fair except for estimated daily discharges, which are poor. 10/01/2017-09/30/2018: Records fair except for estimated discharges, which are poor. 10/01/2018-09/30/2019: Records fair except for estimated discharges, which are poor. 10/01/2019-09/30/2020: Records good except for estimated discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge observed, 3,280 ft³/s, Jul. 10, 11, 1906, gage height, 5.9 ft, site and datum then in use; maximum gage height, 11.82 ft, Jul. 6, 2017; no flow at times, 1924, 1925, 1931, 2015 and 2016.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water years 1960 to Jun. 1996; Nov. 1996 to current year.
PERIOD OF DAILY RECORD - CHEMICAL ANALYSES: Oct. 1968 to Sep. 1969. SPECIFIC CONDUCTANCE: Oct. 1968 to Sep. 1976, once-daily; May 1995 to Jun. 1996, Nov. 1996 to current year, four times per hour. WATER TEMPERATURE: Oct. 1968 to Sep. 1976, once-daily; May 1995 to Jun. 1996, Nov. 1996 to current year, four times per hour.
INSTRUMENTATION - Water quality monitor May 1995 to Jun. 1996, Nov. 1996 to current year, four times per hour.
REMARKS - Inflow from two drainage ditches occasionally enters stream less than a mile above sampling site. Because inflow and streamflow differ in quality, and because the waters do not mix thoroughly above sampling site, flow at site is not homogenous either chemically or thermally when ditches discharge to the stream. Doubtless, this was responsible for some of the variation shown by daily specific-conductance and temperature data during water years 1969-76. Detailed sampling information is available from U.S. Geological Survey, Carson City, NV. Pesticide analyses prior to Oct. 1981 from U.S. Environmental Protection Agency.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum daily, 998 microsiemens, cm at 25°C, Mar. 09, 2014; minimum daily, 100 microsiemens, cm at 25°C, Jun. 12, 2013. WATER TEMPERATURE: Maximum daily, 35.0°C, Jul. 22, 2003, Jul. 26 and 30, 2009, Jul. 21, 2013; minimum daily, 0.0°C, many days during winter months, most years.
