Tom Miller Dam is a dam located on the Colorado River within the city limits of Austin, Texas, United States. The City of Austin, aided by funds from the Public Works Administration, constructed the dam for the purpose of flood control and for generating hydroelectric power. Named after Robert Thomas Miller, a former Mayor of Austin, the dam forms Lake Austin, one of the Texas Highland Lakes.
