This is the authors' summary from a 31-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Lake Jacksonville were surveyed in 2020 using fall electrofishing. Anglers were surveyed March through May 2021 with a creel survey. Historical data are presented with the 2020-2021 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 Jacksonville is a 1,208-acre reservoir on Gum Creek in the Neches River basin, approximately four miles southwest of Jacksonville, Texas. Water level has been within two feet of conservation pool since 2013. The reservoir is clear and low in productivity. Land surrounding the reservoir is highly modified for residential development, and approximately 40% of the shoreline has bulkhead at the land/water interface.

Management History

Important sport fish include Largemouth Bass and crappie. Largemouth Bass are managed with a five fish daily bag; two of which may be less than 18 inches in length. Remaining species are managed under the statewide harvest regulations. Florida Largemouth Bass fingerlings have been stocked frequently since 2010. An integrated vegetation management plan was initiated in 1997 featuring triploid Grass Carp stocking, release of hydrilla flies, herbicide treatments, and native plant introduction. Vegetation surveys were conducted twice a year (pre-treatment in spring and annual in summer) to monitor changes from 2000-2008. Herbicide treatments were conducted annually through 2006. In 2006 and 2007 a total of 3,890 additional triploid Grass Carp were stocked (10 fish/hydrilla acre). In July 2007, a major flood event removed most of the hydrilla, and triploid Grass Carp herbivory prevented reestablishment. By summer 2008 hydrilla was reduced to trace coverage, and native vegetation was sparse. Vegetation surveys were conducted annually (at the peak of the growing season) from 2013-2016.
