Fish populations in Sam Rayburn Reservoir were surveyed in 2010 using electrofishing and in 2011 using gill netting. Anglers were surveyed from June 2010 through May 2011 with a creel survey. This report summarizes the results of the surveys and contains a management plan for the reservoir.

Reservoir Description

Sam Rayburn Reservoir is an 111,422-acre impoundment of the Angelina River in Angelina, Jasper, Nacogdoches, Sabine, San Augustine, and Tyler counties in southeast Texas. Water level fluctuations average 6 to 7 feet annually. Aquatic habitat consisted of aquatic vegetation (primarily hydrilla and American lotus) and standing timber.

Management History

The black bass fishery is the most popular at Sam Rayburn Reservoir (69 - 80% of annual angling effort, which includes over 400 bass tournaments per year). Approximately 10 - 15% of anglers target crappie and 5 - 10% target catfish. Angler interest in more restrictive length limits for largemouth bass and potential biological and economic impacts of bass tournaments prompted research in 2004 to 2009. Results indicated that the proportion of the largemouth bass population harvested was relatively low (9%) and more restrictive length limits would provide little benefit. In addition, impacts of tournaments on the largemouth bass population were low (only 5% of population retained by tournament anglers) but tournament expenditures were high (73% of total). Florida largemouth bass (FLMB) have been stocked annually since 1994 to increase abundance of large bass (>8 pounds). In 2008, giant salvinia was found in the reservoir. Numerous introductions via boat trailers have occurred. Giant salvinia persists in several locations (<5 total acres) and additional spread is likely.
