Twin Buttes Reservoir was surveyed in 2003 using electrofishing and trap nets, and in 2004 using gill nets. 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 located on the South and Middle Concho rivers three miles southwest of San Angelo and is used for municipal water supply and irrigation. The reservoir consists of two main pools connected by an equalization channel. At the time of sampling the reservoir was 50 feet below conservation pool. Low water levels were maintained from 1995-1998 to facilitate repairs to the dam, and long-term drought has prevented the refilling of the reservoir. When full, access is good with 6 ramps and 100% of the shoreline available; however, currently none of the ramps are usable due to the low water level. At the time of sampling, the habitat was primarily nondescript, and rock and gravel shoreline.

Management Strategies

Because of continued extreme low water levels, no changes should be made to the current regulations on Twin Buttes Reservoir. After a significant rise in water level, supplemental sampling will be conducted to determine changes that should be made in stocking and sampling regimes. Supplemental stocking of channel catfish should take place to improve the catfish fishery for bank anglers at Twin Buttes.
