REMARKS - Some records listed in the "Period of Record" for surface water and water quality may not be available electronically. The reservoir is formed by a rolled earthfill dam 4,360 ft long. Deliberate impoundment began in Feb. 1977, and the dam was completed in June 1977. The flood-control outlet works consist of an ungated 100 ft long concrete ogee spillway located at right end of dam. The low-flow outlet works consist of a concrete outlet tower with three 4 by 6 ft slide gates and one 6 by 6 ft slide gate, which feed into a 6 ft inside diameter concrete conduit that extends through the dam. The dam is owned by Texas Utilities Services, Inc. Water can be diverted by pipeline from Lake Granbury (station 08090900) into this reservoir.
