07369500 Tensas River at Tendal, LA
LOCATION - Lat 32°25'55", long 91°22'00" referenced to North American Datum of 1927, in NW 1/4 sec.29, T.17 N., R.11 E., Madison Parish, LA, Hydrologic Unit 08050003, near right bank on upstream side of bridge on U.S. Highway 80 at Tendal, 200 ft upstream from Illinois Central Gulf Railroad bridge, and 2.8 mi east of Waverly.
DRAINAGE AREA - 309 mi².
PERIOD OF RECORD - December 1935 to current year. Monthly discharge only for some periods, published in WSP 1311.
GAGE - Water-stage recorder. Datum of gage is 50.07 ft above NGVD of 1929. Prior to July 11, 1944, nonrecording gage at site 1,000 ft upstream at same datum. July 11, 1944 to Sept. 14, 1954, nonrecording gage at same site and datum. Water-stage recorder for Tensas River southeast of Tendal (07369515) used as auxiliary gage for this station since Oct. 1, 1957. See WSP 1711 and 1731 for history of changes prior to Oct. 1, 1957.
COOPERATION - Corps of Engineers, Vicksburg District.
REMARKS - Records fair except for periods of estimated daily discharge, which are poor. Small diversions above station for irrigation. Interconnecting system of bayous and drainage ditches produces an interchange of flow under varying conditions; hence, the drainage limits were more or less arbitrarily determined. Satellite telemetry at station.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of May 15, 1927 (affected by overflow from Mississippi River) reached a stage of 34.02 ft.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 4,610 ft³/s, Nov. 19, 1948; maximum gage height, 27.21 ft, May 5, 1991; minimum discharge, 1.1 ft³/s, Sep. 20, 2000 and Oct. 26, 2010, but may have been less during period of indefinite stage-discharge relationship in October 1954.
AVERAGE DISCHARGE FOR PERIOD OF RECORD - 78 years (water years 1936 to 2013), 351 ft³/s, 254,300 acre-ft/yr.
