Fish populations in Sam Rayburn Reservoir were surveyed in 2006 using electrofishing and trap nets and in 2007 using gill nets. Anglers were surveyed from June 2006 - May 2007 with a creel. 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 Jasper, Tyler, Angelina, Nacogdoches, San Augustine, and Sabine counties in southeast Texas. Water level fluctuations average 6.7 feet annually. Aquatic habitat consisted of aquatic vegetation (primarily hydrilla and American lotus) and standing timber.

Management History

Historically, the black bass fishery is the most popular at Sam Rayburn Reservoir. Typically, 65 - 75% of annual angling effort is directed at black bass, which includes over 300 bass tournaments per year. Approximately 15 - 20% of anglers target crappie and 4 - 8% target catfish. Angler interest in more restrictive length limits for largemouth bass and potential impacts of bass tournaments prompted research in 2004 - 2007. 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, the research found that impacts of tournaments on the largemouth bass population were low (only 5% of population retained by tournament anglers). Florida largemouth bass (FLMB) have been stocked annually since 1994 to attain > 20% pure FLMB in the population. Palmetto bass were stocked annually from 1995 - 2000 but discontinued due to low angler directed effort and harvest. Introduction of giant salvinia via transport from Toledo Bend Reservoir has been a major concern but has not been documented.
