USGS Water-Year Summary 2021
08210000 Nueces River near Three Rivers, TX
LOCATION - Lat 28°25'38", long 98°10'40" referenced to North American Datum of 1927, Live Oak County, TX, Hydrologic Unit 12110111, on right bank at U.S. Highway 281, 1.0 mi downstream from Frio River, 2.2 mi south of Three Rivers, and at mile 100.2.
DRAINAGE AREA - 15,427 mi².
REVISIONS HISTORY - WSP 548: 1920-21. WSP 1562: 1916, 1918-21, 1922(M), 1923, 1929. WDR TX-83-3: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - July 1915 to current year. Monthly discharge only for Nov. 1919 to Jan. 1920, published in WSP 1312. PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Aug. 1941 to Sept. 1952, May 1965 to Jan. 2010. BIOCHEMICAL DATA: May 1965 to Jan. 2010. BIOLOGICAL DATA: Oct. 1974 to Sept. 1981. PESTICIDE DATA: Jan. 1968 to May 1982, Oct. 1996 to Jan. 2010. SEDIMENT DATA: Oct. 1941 to Aug. 1945, Mar. 1951 to Sept. 1952, Oct. 1974 to Aug. 1994.
GAGE - Water-stage recorder. Datum of gage is 99.26 ft above NGVD of 1929. Prior to Apr. 5, 1932, nonrecording gage at railroad bridge 0.8 mi upstream at datum 1.87 ft higher. Apr. 5, 1932 to Aug. 9, 1983, water-stage recorder at site 0.8 mi upstream at datum 1.87 ft higher. Satellite telemeter at station.
REMARKS - Since Mar. 1948, at least 10% of contributing drainage area has been regulated. Part of the flow of the Nueces and Frio Rivers and their headwater tributaries enters the Edwards and associated limestones in the Balcones Fault Zone that crosses the basin upstream from U.S. Highway 90. Some loss of flow into various permeable formations also occurs downstream from the Balcones Fault Zone. Flow of the Atascosa River at Whitsett (station 08208000) is supplemented during dry periods by discharge from the Campbellton water wells. There are many small diversions for irrigation and for municipal supply above this station. No flow at times. Some records listed in the "Period of Record" for surface water may not be available electronically.
EXTREMES FOR PERIOD PRIOR TO REGULATION - WATER YEARS 1916-1948: Maximum discharge, 85,000 ft³/s, Sept. 18, 1919, gage height, 46.0 ft, site and datum then in use; no flow at times.
AVERAGE DISCHARGE FOR PERIOD PRIOR TO REGULATION - 33 years (water years 1916-48) 945 ft³/s (684,500 acre-ft/yr).
