Lake Wright Patman was surveyed during the period June 2004 to May 2005 using electrofishing, gill netting, trap netting, a littoral zone habitat survey, an aquatic vegetation survey, and an angler access survey. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Wright Patman is located on the Sulphur River. It was constructed by the U. S. Army Corps of Engineers (USACE) in 1956 for flood control, municipal and industrial water supply, and public recreation. It has a drainage area of approximately 3,443 square miles. Shoreline length is 170 miles. Average annual water level fluctuation is 5-10 feet; however, water level fluctuation may be much higher during periods of high rainfall. Littoral area (water depth less than 15 feet) accounts for 58% of the reservoir. Bank fishing and boating access is available at numerous USACE parks and private marinas. Structural habitat is comprised of inundated timber, brush, and riprap. Aquatic macrophytes are present with highest densities in the upper end of the reservoir. Hydrilla coverage was estimated to be 5 acres during the 2004 vegetation survey.

Fish Community

Management Strategies

Based on fish community data, the reservoir should be managed under current harvest regulations. Lake Wright Patman supports excellent catfish, white bass, and crappie fishing opportunities. Special efforts should be made to promote these fisheries. Because Florida largemouth bass alleles were <20% in the latest sample, additional stocking should be requested for 2007 and 2008 at a rate of 25 fish/acre. Electrophoretic sampling should be conducted when necessary to monitor the success of Florida largemouth bass stockings and their genetic influence on the population.
