About Lake Austin
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.
