Lake Austin, formerly Lake McDonald, is a water reservoir on the Colorado River in Austin, Texas in the United States. The reservoir was formed in 1939 by the construction of Tom Miller Dam by the Lower Colorado River Authority. Lake Austin is one of the seven Highland Lakes created by the Lower Colorado River Authority, and is used for flood control, electrical power generation, and recreation. Loop 360 spans the lake at the Pennybacker Bridge.
The other reservoirs on the Colorado River are Lake Buchanan, Inks Lake, Lake LBJ, Lake Marble Falls, Lake Travis, and Lady Bird Lake.
Lake Austin is a popular fishing and boating destination. The lake is considered to have an excellent stock of largemouth bass. However, most people feel that the lake is best utilized for pleasure boating during the day.
Fish and wildlife populations
Lake Austin has been stocked with several species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in Lake Austin include largemouth bass, catfish, and sunfish. Lake Austin is one of the Texas Highland Lakes infested with hydrilla, a non-native aquatic plant species. The Lower Colorado River Authority has intentionally lowered the water levels in the lake in the months of January and February so that freezing air temperatures might destroy substantial portions of the hydrilla in the lake each winter. As of March 2014, hydrilla has been completely eliminated from the lake through the stocking of Asian Grass Carp by the City of Austin
