Lake Austin is a part of Texas' [[Colorado River (Texas)|Colorado River]]; it begins below [[Mansfield Dam]] and is principally fed by the outflow of [[Lake Travis]]. The lake [[meander]]s generally from northwest to southeast, with few significant [[Tributary|tributaries]]; the largest are [[Bull Creek (Texas)|Bull Creek]], entering from the north near where [[Texas State Highway Loop 360|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 [[Texas Highland Lakes|Highland Lake]] reservoirs on the Colorado River are [[Lake Buchanan (Texas)|Lake Buchanan]], [[Inks Lake]], [[Lake LBJ]], [[Lake Marble Falls]], and Lake Travis upstream, and Lady Bird Lake downstream.
