This is the authors' summary from a 22-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Twin Buttes Reservoir were surveyed in 2009 and 2011 using electrofishing and trap nets, and in 2009-2010 using an access creel survey. Planned gill net sampling was not conducted due to low water levels in 2012. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Twin Buttes Reservoir is a 9,080-acre (currently 689-acre) impoundment located 3 miles southwest of San Angelo, Texas in Tom Green County. The reservoir consists of two pools (“North Pool” and “South Pool”) connected by an equalization channel. This hypereutrophic reservoir experiences dramatic water level fluctuations, and has extensive fish habitat mostly in the form of flooded terrestrial vegetation. Boating access was poor due to low water levels.

Management History

Important sport fish include white bass, largemouth bass, white crappie, and catfishes. Striped bass were stocked in 1995, and are still occasionally caught by anglers or in gill nets. Sport fishes have been managed with statewide regulations.
