Fish populations in Nasworthy Reservoir were surveyed in 2018 using electrofishing, trap netting and in 2019 using gill netting and tandem hoop netting. Anglers were surveyed from June 2018 through May 2019 with a creel survey. Historical data are presented with the 2018-2019 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

Nasworthy Reservoir is a 1,380-acre impoundment located on the southwestern edge of San Angelo, Texas in Tom Green County. It is a shallow turbid reservoir with stable water levels and extensive emergent vegetation. Access is good with numerous public boat ramps and parks.

Management History

Important sport fish include Largemouth Bass, White Crappie, and Channel Catfish. Red Drum were once an important game species, but the discontinued operation of the power plant on Nasworthy Reservoir in 2003 eliminated this fishery that was dependent on the plant’s heated water effluent. Palmetto Bass (Striped Bass x White Bass hybrid) were stocked from 1974 to 2007. In 2018 Palmetto Bass stockings resumed at a higher stocking density in an attempt to restructure the Gizzard Shad population.
