SURFACE-WATER RECORDS

PERIOD OF RECORD - Aug. 1939 to current year. PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Oct. 1959 to Oct. 1991. BIOCHEMICAL DATA: Oct. 1959 to Sept. 1973. PESTICIDE DATA: Sept. 1966, Nov. 1971, Feb. 1989. RADIOCHEMICAL DATA: Dec. 1980, Feb. 1981 to May 1981. SEDIMENT DATA: May 2006 to July 2007.

GAGE - Water-stage recorder. Datum of gage is 26.53 ft above NGVD of 1929. Datum of gage is 25.948 ft. above NAVD88. Aug. 5, 1939, to Aug. 29, 1984, on left bank 9.0 ft upstream at datum 1.0 ft higher. Aug. 29 to Nov. 5, 1984, on left bank 9.0 ft upstream at present datum. Nov. 5, 1984, to Aug. 5, 1987, on left bank 154 ft downstream at present datum. Satellite telemeter at station.

REMARKS - Since installation of gage at least 10% of contributing drainage area has been regulated. Upstream from Lake Corpus Christi, flow is affected by recharge to permeable formations, small diversions, and minor regulation. Water for municipal and industrial uses at the City of Corpus Christi is released from Lake Corpus Christi above gage and is diverted from river at Calallen 34.0 mi downstream. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
