This is the authors' summary from a 27-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Lake Raven were surveyed in 2013 using electrofishing and trap netting and in 2014 using gill netting. Anglers were surveyed from March 2013 through May 2013 with a creel survey. Historical data are presented with the 2013-2014 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Raven is a 203-acre reservoir located in Huntsville State Park. The reservoir was repaired and re-impounded in 1956 by the Texas Parks & Wildlife Department for recreational use.

Management History

Lake Raven has a history of producing trophy Largemouth Bass. The population has been managed with a catch-and-release regulation since September 1996. The regulation allows the angler to retain Largemouth Bass measuring > 24 inches for weighing on a personal scale in the boat with subsequent release or, if weighing 13 pounds or more, donation into the Toyota ShareLunker Program. Lake Raven has been included in the Operation World Record (OWR) program, a project designed to compare growth of selectively-bred ShareLunker Largemouth Bass fingerlings to resident bass fingerlings.

Alligatorweed, hydrilla, giant salvinia and water hyacinth have all been problem exotic plants to varying degrees at different times. Aquathol, Galleon, Glyphosate, Diquat, and Stingray have all been used for chemical treatments. In addition, Grass Carp, hydrilla flies, and alligator weed flea beetles have been used as biological control agents. Mechanical control and manual removal have also been used as part of an integrated pest management approach.

Management Strategies

We will monitor the Largemouth Bass population every two years in the fall with electrofishing or as appropriate as part of the OWR program. Largemouth Bass genetics will be assessed, and additional ShareLunker Largemouth Bass fingerlings will be stocked as dictated by the OWR program. Crappie populations will also be monitored during electrofishing surveys. Catfish populations will be monitored every 4 years by gill nets with surplus catfish fingerlings requested for stocking when available. An access point creel survey will be conducted in the spring of 2017. We will continue to work with park personnel to assess exotic vegetation coverage and implement treatment strategies including native vegetation plantings and bio-control efforts as needed.
