BIOLOGICAL DATA: Feb. 1978 to July 1993. PESTICIDE DATA: Aug. 1969 to June 1982. RADIOCHEMICAL DATA: Mar. 1981 to Sept. 1981. SEDIMENT DATA: Feb. 1978 to July 1993.

GAGE -

Water-stage recorder. Satellite telemetry at station.

Datum of the gage: 281.934 ft NAVD88 based on a Level 2 Static GNSS survey processed through OPUS and Ref Frame NAD83 (2011)(EPOCH:2010.0000) ITRF2014 (EPOCH:2022.1146) and Geoid 18. The survey was completed on 2/11/2022 while occupying a TRM referenced to local gage datum via differential levels.

Prior to 2/11/2022: the Datum of gage was 281.89 ft above NGVD of 1929 (levels by U.S. Army Corps of Engineers). Nov. 1916 to Sept. 1922, nonrecording gage at site 2.2 mi upstream at different datum. Oct. 1922, to Apr. 1926, nonrecording gage at McCowan bridge 1,990 ft upstream at same datum. Apr. 1926 to Oct. 1933, non-recording gage at same location but at l.58 ft lower datum. Oct. 1933 to Aug. 1992, recording gage at site 2,020 ft upstream at same datum. Aug. to Oct. 1992, non-recording gage at site.

REMARKS - Records fair. Since water year 1954, at least 10% of contributing drainage area has been regulated. Many small diversions for irrigation and municipal supply affect low flow. The Aluminum Company of America diverts water 10.9 mi upstream from the gage for use at their Rockdale plant resevoir. The city of Cameron diverts water for municipal use 2.1 mi upstream from gage. Wastewater effluent is returned to the river upstream from gage. No flow at times. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.

EXTREMES OUTSIDE PERIOD OF RECORD - Flood in 1852 reached about the same stage as that of Sept. 10, 1921. Flood in Dec. 1913, reached a stage of 49.0 ft. Stages based on information furnished by local resident.

EXTREMES FOR PERIOD PRIOR TO REGULATION - WATER YEARS, 1917-1953: Maximum discharge since 1852, 647,000 ft³/s, Sept. 10, 1921 (gage height, 53.2 ft, present datum, from floodmark), from rating curve extended above 110,000 ft³/s, on basis of slope-area measurement of 647,000 ft³/s.

AVERAGE DISCHARGE FOR PERIOD PRIOR TO REGULATION - 36 years (water years 1917-53), prior to regulation by Belton Lake, 1,807 ft³/s (1,309,000 acre-ft/yr).
