This is the authors' summary from a 28-page report. For a copy of the complete report, use the download link in the sidebar.

Lake Murvaul was surveyed within the period of 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. Additional electrofishing surveys were conducted during fall 2001, 2002, and 2003. Roving creel surveys were also conducted March through May 2002 (9 days) and June 2003 through May 2004 (36 days). This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Murvaul is located on Murvaul Creek in the Sabine River Basin. It was constructed by the Panola County Fresh Water Supply District in 1957 for municipal and industrial water supply and public recreation. The reservoir lies within the East Texas Timberlands Land Resource Area. It has a drainage area of approximately 115 square miles. The reservoir covers 3,820 acres and its shoreline length is 29 miles. Water levels are relatively stable; average annual fluctuation is 2 feet. Boating access is available at four parks; three public and one private. Structural habitat is comprised of inundated timber, brush, riprap, boat docks, and bulkhead. Aquatic macrophytes are present in moderate densities throughout the reservoir. Hydrilla, a non-native aquatic plant once covering approximately 27% of the reservoir surface area, was not found during the 2000 vegetation survey. However, only 2 acres of hydrilla was observed during the 2004 vegetation survey. American lotus is the dominant aquatic macrophyte species covering < 1% (93 acres) of the reservoir. Lake Murvaul received national recognition during the 1960s for its trophy native largemouth bass population. Following the introduction of Florida largemouth bass, Lake Murvaul anglers have continued catch large bass. From 1987 to 1997, six largemouth bass >13 lbs. have been entered into the TPWD ShareLunker Program. The current lake record is 14.87 lbs.

Management Strategies

Based on these findings, the reservoir should be managed under current harvest regulations. The special 14-21 inch slot-length limit for largemouth bass is in its sixth year and will be evaluated following fall electrofishing in 2005. Following this evaluation, fall electrofishing will be conducted every other year beginning in 2008. Because of the trophy potential of this reservoir, Florida largemouth bass will be requested to be stocked in 2006 and 2007 to increase the percentage of pure Florida largemouth bass in the population.
