Fish populations in Lake Texana were surveyed in 2006 using trap nets and electrofishing and in 2007 using gill nets. This report summarizes the results and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Texana is 9,727-acres (previously listed at 10,628 acres), controlled by the Lavaca-Navidad River Authority (LNRA), and located on the Navidad River in the Lavaca River Basin, approximately 20 miles east of Victoria. It receives water from the Navidad River, Sandy Creek, and Mustang Creek and is used for water supply and recreation. Water level typically fluctuates 2-4 ft annually but can fluctuate as high as six feet.

Management History

Important sport fish species include blue, channel, and flathead catfish, white bass, largemouth bass, and white and black crappie. Palmetto bass had been previously stocked in the reservoir. The 2003 management plan focused on issues with largemouth bass reproduction, palmetto bass stockings, exotic aquatic vegetation, and the potential for increased water level fluctuations. Spring largemouth-bass-only electrofishing surveys were conducted in 2004, 2005, and 2007, with largemouth bass only being collected in 2007 survey. Palmetto bass stockings were discontinued due to low gill net catch rates. Treatment proposals were submitted and control efforts were implemented for giant salvinia (biological control agents and herbicides), water hyacinth (herbicides), and hydrilla (biological control agents). Water level fluctuations were monitored via the internet.
