Lake Wood (H-5) was surveyed in fall 2005, 2007, 2009, 2011 and spring 2009 and 2012 using electrofishing, fall 2005, 2007, 2009, and 2011 using trap nets and spring 2004, 2008, and 2012 using gill nets. This report summarizes the results of these surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Lake Wood (488 acres) is located on the Guadalupe River in Gonzales County, and was constructed in 1931 by the Texas Hydroelectric Commission. Its main purposes are for water supply, hydro-power production and recreation. Angler and boat access is adequate with two public boat ramps; however there are no handicap-specific facilities at either location. Habitat consisted of boat docks, rocks, floating-leaved vegetation, emergent vegetation, exotic vegetation (water hyacinth, water lettuce) and stumps. Hydrilla has not been observed in the reservoir since 2004. Water hyacinth and water lettuce was present and has the potential to create access problems.

Management History

Important sport fish include channel and flathead catfish, largemouth bass, and crappie. White bass are present in this reservoir but in low abundance. Blue catfish have been stocked in this reservoir but are not the dominant catfish species. The 2008 management plan focused on working with GBRA on the control of water hyacinth, monitoring water lettuce and East Indian hygrophila, and conducting spring electrofishing surveys to assess perceived spawning and recruitment issues of largemouth bass. Guadalupe Blanco River Authority (GBRA) controlled nuisance aquatic vegetation (primarily water hyacinth) through contracted herbicide spraying operations and winter time lake drawdowns. Combined, these efforts were effective at controlling water hyacinth. TPWD monitored water lettuce and East Indian hygrophila, but neither plant became problematic in 2011. Spring electrofishing surveys were conducted and the data showed both spawning success and recruitment were no longer a problem.
