This is the authors' summary from a 44-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Coleto Creek Reservoir were surveyed in 2016 using electrofishing and in 2017 using gill nets and baited tandem hoop nets. Creel surveys were conducted from 1 January 2017 through 30 June 2017. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Coleto Creek Reservoir is a 3,100-acre (averaged 2,923 acres in 2016-2017) reservoir located on Coleto Creek in the Guadalupe River Basin, 13 miles southwest of Victoria, Texas. Regulated by the Guadalupe-Blanco River Authority (GBRA), the reservoir receives water from Coleto and Perdido creeks as well as several smaller tributaries. Primary uses include power plant cooling and recreation. Approximately 600 acres are used for cooling ponds and inaccessible to anglers. Water level is typically stable; however, over the survey period water levels fluctuated 2.5 feet from conservation pool. Substrate is composed primarily of clays, deep loams and small rock. Littoral habitat consisted primarily of flooded terrestrial vegetation, floating-leaved native vegetation, water hyacinth, and flooded timber.

Management History

Important sport fish species include Blue and Channel catfishes, White Bass, Largemouth Bass, and White and Black crappies. Angler harvest of all sport fishes has been regulated according to statewide size and bag limits. Palmetto Bass and Red Drum were previously stocked in the reservoir but these stockings were discontinued due to low directed angling effort. Recent management efforts focused on control of nuisance aquatic vegetation, compiling catch and harvest statistics on important sport fish populations, and exploratory use of low-frequency electrofishing to collect population data on catfishes. District staff also conducted additional Largemouth Bass sampling to estimate total annual mortality and compiled tournament data records to document catches of larger fish. Historically, invasive aquatic vegetation (hydrilla, water milfoil, and water hyacinth) has restricted access. District staff worked with GBRA and herbicides were utilized as needed.
