10336730 Glenbrook Creek At Glenbrook, NV
LOCATION - Lat 39°05'15", long 119°56'20" referenced to North American Datum of 1927, in NE 1/4 SE 1/4 sec.10, T.14 N., R.18 E., Douglas County, NV, Hydrologic Unit 16050101, on right bank, 50 ft upstream from culvert, 100 ft upstream from mouth at Glenbrook, and 1.8 mi southwest of Spooner Lake.
DRAINAGE AREA - 4.11 mi².
REVISIONS HISTORY - WDR NV-00-1: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - Occasional low-flow measurements, water years 1967-1971. Oct. 1971 to Sep. 1975, Nov. 1987 to current year.
GAGE - Water-stage recorder. Elevation of gage is 6,240 ft above National Geodetic Vertical Datum of 1929, from topographic map. Prior to Nov. 16, 1987, at different datum.
REMARKS - Flow may be affected by pumping or diverting for irrigation above station. 10/01/2013-09/30/2014: Records fair except for estimated discharges, which are poor. 10/01/2014-09/30/2015: Records fair except for estimated discharges, which are poor. 10/01/2015-09/30/2016: Records fair except for estimated discharges, which are poor. 10/01/2016-09/30/2017: Records fair. 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 fair except for estimated discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 144 ft³/s, Jan. 02, 1997, gage height, 6.46 ft; no flow Aug. 12, 1994.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water years 1971-74, Jul. 1987, 1988 to Sept. 2011 (discontinued).
PERIOD OF DAILY RECORD - WATER TEMPERATURE: Apr. 1998 to Nov. 2000, discontinued.
INSTRUMENTATION - Water temperature recorder Apr. 1998 to Nov. 2000, two times per hour.
REMARKS - In Nov. 1987, station was incorporated into the expanded Lake Tahoe Interagency Monitoring Program to monitor tributary contributions of nutrients and sediment to Lake Tahoe. Nutrient samples were analyzed by the University of California, Davis, Tahoe Research Group. Quality assurance samples associated with the entire Lake Tahoe Interagency Monitoring Program are listed under station numbers 103366769999 and 103367309999. The original hydrazine method used to determine nitrate plus nitrite concentrations (parameters 00631 and 00630) was found to have interferences caused by calcium and magnesium in stream water samples. The nitrate plus nitrite concentrations under parameters 99911 and 99910 are based on a laboratory method that uses pyrophosphate to remove interferences caused by calcium and magnesium. This method has replaced the original hydrazine method as of December 2008. Parameter code 00623, filtered ammonia plus organic nitrogen (dissolved Kjeldahl nitrogen) was discontinued in April 2011.
EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 16.0°C, Jun. 15, 2000; minimum, freezing point several days in winter months.
