This is the authors' summary from a 37-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Inks Reservoir were surveyed in 2013 using electrofishing and in 2014 using gill netting. Historical data are presented with the 2013-2014 data for comparison. This report summarizes the results of the surveys and contains a fisheries management plan for the reservoir based on those findings.

Reservoir Description

Inks Reservoir is a 768-acre impoundment of the Colorado River. It was constructed in 1938 by the Lower Colorado River Authority (LCRA) for purposes of hydroelectric power, recreation and water supply. The reservoir lies within the Edwards Plateau eco-region, and its shoreline length is 20.5 miles. Inks Lake State Park borders the reservoir and provides access to approximately 30 percent of the shoreline. The remaining shoreline has either been developed by private property owners or is under control by the LCRA.

Management History

Important sport fish include Largemouth Bass, White Bass, and catfish species. Recent management plans have recommended continuing monitoring populations under existing regulations. The Florida subspecies of Largemouth Bass was stocked in the reservoir in the late 80s and early 90s to increase Florida Largemouth Bass genetic influence in the population. Channel Catfish have been stocked by the Inks Dam National Fish Hatchery through an agreement with the LCRA or when surplus fish become available.

Management Strategies

The reservoir should continue to be managed with existing fishing regulations. The Largemouth Bass, catfish and sunfish fisheries provide good opportunity for state park visitors. The Texas Parks and Wildlife Department (TPWD) Free Fishing in State Parks program is a great incentive to introduce new anglers to fishing. Efforts should be made to further promote fishing opportunities in this reservoir. General fish population monitoring with gill nets and electrofishing should be conducted in the 2017/2018 sampling season. An additional gill netting survey should be conducted in spring 2016 to monitor White Bass abundance, if no significant flows are reestablished by then.
