Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
08376300 Sanderson Creek at Sanderson, TX
LOCATION - Lat 30°07'42", long 102°23'04" referenced to North American Datum of 1927, Terrell County, TX, Hydrologic Unit 13040208, on left bank at upstream side of bridge on U.S. Highway 90, 1.0 mi south of Sanderson, 2.9 mi downstream from Three Mile Draw, and 30.0 mi upstream from mouth.
DRAINAGE AREA - 195 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - Feburary 1968 to Sept. 1980, Oct. 2006 to current year (daily mean discharge), Aug. 2001 to Sept. 2006 (gage heights only). Published as "Sanderson Canyon" prior to Oct. 1979.
GAGE - Water-stage recorder. Datum of gage is 2,706.35 ft above the NGVD of 1929. Prior to Oct. 19, 1977, at site on right bank 95 ft downstream at same datum. Satellite telemeter at station.
REMARKS - Flow is affected at times by discharge from the flood-detention pools of floodwater-retarding structures. No flow most times each year. Some records listed in the period of record may not be available electronically.
EXTREMES OUTSIDE PERIOD OF RECORD - Maximum flood since at least 1935, 14.2 ft June 11, 1965, discharge about 100,000 ft³/s, by combining two slope-area measurements within 4.0 mi upstream from gage. A flood in 1935 reached a discharge of about 20,000 ft³/s, estimated channel capacity by Corps of Engineers.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 32,600 ft³/s, Sept. 18, 1969, gage height, 9.18 ft, from rating curve based on a step-backwater analysis below 10,000 ft³/s and two combined slope-area measurements of about 100,000 ft³/s; maximum gage height, 9.44 ft, Apr. 30, 1974; no flow most of the time each year.
AVERAGE DISCHARGE FOR PERIOD OF RECORD - 12 years (water years 1969-80), 8.51 ft³/s (6,170 acre-ft/year).
