Tom Miller Dam

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.

The dam began operating in 1940 and is located at the site of the city's two previous dams, each of which were destroyed during major floods and shared the same name, Austin Dam. It is currently leased to the Lower Colorado River Authority, who maintains and operates the dam.
