Lake Austin, formerly Lake McDonald, is a water reservoir on the Colorado River in Austin, Texas. Lake Austin is one of the seven Highland Lakes created by the LCRA, and is used for flood control, electrical power generation, and recreation. 


Lake Austin is a part of the Colorado River; it begins below Mansfield Dam and is principally fed by the outflow of Lake Travis. The lake meanders generally from northwest to southeast, with few significant tributaries; the largest are Bull Creek, entering from the north near where Loop 360 spans the lake at the Pennybacker Bridge, and Bee Creek, entering from the west just above Tom Miller Dam, where the lake ends. Its outflow through Tom Miller Dam then becomes the principal inflow for Lady Bird Lake.Lake Austin is maintained as a constant-level lake by releases of water from Lake Travis upstream. The other Highland Lake reservoirs on the Colorado River are Lake Buchanan, Inks Lake, Lake LBJ, Lake Marble Falls, and Lake Travis upstream, and Lady Bird Lake downstream.(Wikipedia, the free encyclopedia)

The Barton Springs Pool
The pool is popular year-round because the temperature of the springs stays a constant 68 degrees Fahrenheit (20 degrees Celsius). There is always some acoustic music and drumming on the lawn surrounding the springs. Tops for the ladies are optional.
