This is the authors' summary from a 36-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in Inks Reservoir were surveyed in 2017 using electrofishing and in 2018 using gill netting. Historical data are presented with the 2017-2018 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) hydroelectric power, recreation, and water supply. The reservoir is located within the Llano uplift eco-region, and its shoreline length is 20.5 miles. Public access is only available through the state park. This stable-level rocky reservoir has plenty of structural fish habitat and some cover in the form of timber, emergent aquatic vegetation, and artificial fish attractors.

Management History

Sport fish include Largemouth Bass, sunfish species, Morone species, 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 1980s and early 1990s 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. Efforts to develop a trophy Sunshine Bass fishery were started in 2016. Recent efforts to mitigate the loss of fish habitat, due to reservoir aging, have included installing artificial and natural cover habitat, sunfish spawning gravel beds, and underwater green lights.
