Lake Jacksonville was surveyed during the period June 2004 to May 2005 using electrofishing, trap netting, gill netting, a littoral zone habitat survey, an aquatic vegetation survey, and an angler access and facilities survey. 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 (a tributary of the Neches River), Texas, built to provide water for municipal and industrial purposes. Boat and bank angler access is adequate. Handicap-specific facilities are present in the parking lot and restrooms near the main boat ramp. Water is clear and very low in productivity (mean mg/m3 chlorophyll a = 1.41). Fertilization of 300 acres was initiated in 1993 to increase primary productivity, but was discontinued in 1995 after hydrilla was discovered. An integrated vegetation management plan was initiated in 1997 in an attempt to control hydrilla and diversify the native plant community. The plan had three phases: phase 1 included herbicide control of the hydrilla; phase 2 called for construction of a fish barrier at the outflow and limited stocking (200 fish) of triploid grass carp; phase 3 included introduction of native aquatic plants to diversify the plant community. In spring 1999 the City of Jacksonville removed the fish barrier in the belief that it caused flooding of low-lying properties; thereby preventing any additional grass carp stocking. Annual hydrilla control has continued with herbicide and physical removal. However, hydrilla has continued to expand in coverage.

Management Strategies

Based on current information, Lake Jacksonville fishing regulations should be maintained at their current status. Because of the importance of the largemouth bass fishery at Lake Jacksonville, biennial electrofishing and electrophoretic sampling should continue with the next sampling scheduled for fall 2006. Annual assessment of hydrilla coverage should be continued with a yearly vegetation survey. To allow for a greater range of control techniques the City of Jacksonville should be encouraged to rebuild the fish barrier at the outflow to allow stocking of additional grass carp as was recommended in the integrated management plan. To promote the fishery and clarify harvest regulations angler information projects should be continued utilizing news releases, regulation posters, public presentations, and the TPWD web site.
