PERIOD OF RECORD, Water-Quality.--
CHEMICAL DATA: Jan. 1964 to Apr. 1976.
GAGE - Water-stage recorder. Datum of gage is 0 ft above NGVD of 1929 and 1.16 ft below NAVD of 1988. To obtain elevation values in NAVD 1988, add 1.16 ft. Satellite telemeter at station.
REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. In 1954 the original lake was formed by an earthfill dam 2,000 ft across Big Sandy Creek for the City of Bowie. In 1985 a new reservoir dam was completed 1.0 mi below the old dam. The old and new portions of the reservoir are connected by a corrugated metal pipe arch culvert (boat pass breach) with an invert elevation of 908 ft NGVD of 1929. The reservoirs are also connected by a 12 in siphon pipe through the old dam. Both reservoirs employ the emergency spillway on the old reservoir to pass flood water above elevation of 927 ft NGVD of 1929. The principal spillway tower has a 24 ft uncontrolled weir at 920 ft NGVD of 1929. Data regarding the dam are given in the following table:
Elevation (feet) Top of new dam........................................................ 945.0 Crest of spillway..................................................... 927.0 Uncontrolled weir..................................................... 920.0 Pipe arch culvert (boat pass breach).................................. 908.0
EXTREMES FOR PERIOD OF RECORD - Maximum contents, 38,060 acre-ft, Mar. 1, 2001, elevation, 924.46 ft; minimum contents, 14,180 acre-ft, Oct. 13, 2000, elevation, 910.18 ft; maximum elevation, 928.75 ft, May 20, 2015.
