SURFACE-WATER RECORDS

PERIOD OF RECORD - Oct. 1923 to current year. PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Oct. 1980 to Aug. 2004. BIOCHEMICAL DATA: Oct. 1980 to Aug. 2004. RADIOCHEMICAL DATA: Jan. 1981 to Aug. 2004. SEDIMENT DATA: Sept. 1964.

GAGE - Water-stage recorder. Datum of gage is 561.79 ft above NGVD of 1929 and 560.86 ft above NAVD of 1988. To obtain elevations in NAVD 1988, subtract 0.93 ft. Prior to May 7, 1931, nonrecording gage at site 0.1 mi downstream at datum 6.03 ft higher. May 7, 1931, to Sept. 30, 1957, water-stage recorder at site at datum 6.03 ft higher, used as supplementary gage Oct. 1, 1957, to Apr. 1, 1959. Apr. 27, 1950, to Sept. 30, 1957, water-stage recorder at site 2.4 mi upstream at datum 6.03 ft higher, used as supplementary gage. Oct. 1, 1957 to Apr. 12, 2002, water-stage recorder at site 2.4 mi upstream at datum 6.03 ft higher. Satellite telemeter at station.

REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. Since 1941, at least 10% of contributing drainage area has been regulated. There are many diversions above station for irrigation and municipal supplies, and oil field operations.

EXTREMES OUTSIDE PERIOD OF RECORD - Second highest known flood since at least 1876 occurred in May 1922 and reached a stage of 29.5 ft, and flood in May 1908 reached a stage of 27 ft, each at present site and datum then in use, from information by local residents.

EXTREMES FOR PERIOD PRIOR TO REGULATION - WATER YEARS, 1924-1940: Maximum discharge, 97,600 ft³/s May 18, 1935 (gage height, 23.68 ft, from floodmarks); no flow at times prior to construction of Morris Sheppard Dam in 1941 on the Brazos River, forming Possum Kingdom Lake.

AVERAGE DISCHARGE FOR PERIOD PRIOR TO REGULATION - 17 years (water years 1924-40) prior to regulation by Possum Kingdom Lake, 1,581 ft³/s (1,145,000 acre-ft/yr).

WATER-QUALITY RECORDS

PERIOD OF RECORD - CHEMICAL DATA: Aug. 1946 to Nov. 1946, Oct. 1980 to June 1987, Oct. 1998 to current year. BIOCHEMICAL DATA: Oct. 1980 to June 1987, Oct. 1998 to current year.
