Reservoir Description

Austin Reservoir is a stable-level 1,589-acre riverine-type impoundment of the Colorado River located in the heart of the City of Austin (COA). It was constructed in 1893 for hydro-electric power, municipal water supply, water conservation and recreation. The reservoir is used to pass water from Travis Reservoir downstream. The reservoir is operated by COA and the Lower Colorado River Authority (LCRA). The reservoir lies within the Edwards Plateau and has a catchment area of approximately 38,240 square miles. Land surrounding the reservoir is highly developed with commercial and residential property bordering most of the shoreline. Natural habitat features consisted of boulders and emergent aquatic plants.

Management History

Important sport fish include Largemouth Bass. The 2012 management plan included stocking Florida Largemouth Bass to maintain high genetic influence, and managing invasive levels of hydrilla. Largemouth Bass have been managed under statewide regulations. Other species of interest are Common Carp and Smallmouth Buffalo; the reservoir has been promoted as a prime destination for bank anglers pursuing these species. The triploid Grass Carp permit was lifted in 2016 to allow for harvest and help restore aquatic vegetation in the reservoir.
