USGS Water-Year Summary 2023

10312210 Stillwater Point Reservoir Diversion Canal Near Fallon, NV

LOCATION - Lat 39°28'23.89", long 118°35'55.06" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 sec.34, T.19 N., R.30 E., Churchill County, NV, Hydrologic Unit 16050203, on left bank, 0.2 mi downstream from a diversion structure for Stillwater Slough, and 9.8 mi east of Fallon.

DRAINAGE AREA - Indeterminate.

SURFACE-WATER RECORDS

PERIOD OF RECORD - Aug. 1967 to Sep. 1981 (monthly discharge only), Oct. 1990 to Sep. 1992, Jan. 1993 to current year. Prior to Oct. 1992, published as Stillwater Diversion Canal near Fallon.

GAGE - Water-stage recorder. Elevation of gage is 3,915 ft above National Geodetic Vertical Datum of 1929, from topographic map. Prior to Sep. 1981, gage at same site and datum on right bank.

REMARKS - 10/01/2013-09/30/2014: Records fair except estimated daily discharges, which are poor. 10/01/2014-09/30/2015: Records fair except estimated daily discharges, which are poor. 10/01/2015-09/30/2016: Records fair except estimated daily discharges, which are poor.

EXTREMES FOR PERIOD OF RECORD - Maximum daily discharge, 256 ft³/s, Jan. 29, 1997; no flow several days many years.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Apr. 1977 to Sep. 1981, Sep. 1990 to Aug. 1992, Jan. 1993 to Sep. 2015 (discontinued).

PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Sep. 1990 to Aug. 1992, Jan. 1993 to Sep. 2015 (discontinued). WATER TEMPERATURE: Oct. 1990 to Aug. 1992, Jan. 1993 to Sep. 2015 (discontinued).

INSTRUMENTATION - Water-quality monitor Sep. 1990 to Aug. 1992 and Jan. to Jun. 1993, hourly; Jul. 1993 to Jan. 1994, four times per hour; Feb. to Sep. 1994, hourly, Oct. 1994 to Sep. 2015 (discontinued), four times per hour.

REMARKS - Instantaneous specific-conductance and water-temperature measurements during a site visit can be slightly outside the range of values recorded during the same day by the water-quality monitor. This presumably is due to fluctuations in conductance and temperature during the interval between periodic monitor recordings. In Mar. 1994, station was incorporated into the Stillwater Environmental Monitoring Program to gage environmental changes that may occur as a result of change in management of irrigation water of the Newlands Irrigation Project.

EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum recorded, 9,620 microsiemens, cm at 25°C, Apr. 8, 1995; minimum recorded, 202 microsiemens, cm at 25°C, May 31, 1996. WATER TEMPERATURE: Maximum recorded, 31.5°C, Aug. 12, 1992; minimum recorded, 0.0°C, many days during winter months.
