Reservoir Description

Austin Reservoir is a stable-level 1,599-acre riverine type impoundment of the Colorado River located in the heart of the City of Austin (COA). It was constructed in 1893 for purposes of 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 the Lower Colorado River Authority (LCRA) and COA. The reservoir lies within the Edwards Plateau and has a drainage 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, native and non-native submerged aquatic plants, including hydrilla (Hydrilla verticillata).

Management History

Important sport fish include Largemouth Bass and catfish. The management plan from the 2008 survey report included stocking Florida Largemouth Bass to maintain high genetic influence and managing invasive levels of hydrilla. Largemouth Bass have been managed under statewide regulations.
