Fish populations in Grapevine Reservoir were surveyed in 2004-2007 using electrofishing, in 2007 using trap netting, and in 2008 using gill nets. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.
Grapevine Reservoir is a 6,684-acre impoundment constructed on Denton Creek, a tributary of the Trinity River by the U.S. Army Corps of Engineers in 1952 to provide flood control, municipal and industrial water, and recreation. Grapevine Reservoir is surrounded by urban development and is 20 miles northwest of Dallas, Texas in Tarrant County. The reservoir contains 188,550 acre-feet of water at conservation elevation (535 ft. mean sea level) and has an average depth of 28.2 feet and a maximum depth of 65.0 feet. Angler and boat access is adequate. There is one handicap specific facility on the reservoir. At the time of sampling the fishery habitat was primarily rocky and gravel shorelines. A 14- to 18-inch slot-length limit was implemented for largemouth bass on September 1, 1994. Grapevine Reservoir has been part of the TPWD Habitat Improvement Initiative since 1997; however, because of water level fluctuations there has been limited success.
Important sport fish include largemouth bass, spotted bass, white crappie, white bass, and blue and channel catfish. The largemouth bass population has been managed with a 14- to 18-inch slot-length limit since 1994. All other species have been managed with statewide regulations.
- Prey species: Gizzard shad are in great abundance in the reservoir. Threadfin shad are also available for predators. Bluegills and longear sunfish are also very abundant as prey but few fish over 6 inches are available for anglers.
- Catfishes: The blue catfish population continues to improve. The channel catfish population is average.
- White bass: White bass catch rates continue to be below the average of other district reservoirs.
- Black basses: The largemouth bass and spotted bass populations continue to have good abundance and size structure.
- Crappie: The white crappie population continues to be low in abundance when compared to other district reservoirs.
- Electrofishing will be conducted annually to monitor black bass populations. Trap netting, and gill netting surveys will be conducted in 2011-2012.
