The Mansfield Dam is a 278-foot-tall gravity dam constructed primarily to regulate the flow of the Colorado River.
The park provides access to one of the deepest portions of Lake Travis, making it a popular site for recreational scuba diving.
Lake Travis, the reservoir created by the dam, is known for its fluctuating water levels which can change significantly depending on regional rainfall.
The park includes a dedicated scuba training area near the dam wall.
The dam serves as a bridge for FM 620, a major thoroughfare in the Austin metropolitan area.
Mansfield Dam Park is a 70-acre lakeside recreation area located on the shores of Lake Travis in Austin, Texas. The park is uniquely positioned at the base of the historic Mansfield Dam, which was completed in 1941 as a flood control and power generation structure. It features direct access to the lake for swimming, boating, and scuba diving. The site provides a dedicated boat ramp and multiple picnic areas equipped with grills. The grounds contain approximately 3.2 miles of paved trails suitable for walking and cycling. The park offers panoramic views of the water and the spillway of the dam itself. It serves as a primary hub for water-based activities in the region due to its deep-water access. The terrain includes limestone bluffs and native vegetation consistent with the Texas Hill Country ecosystem. Public facilities include restrooms, shade structures, and large open lawn areas.

Bring water shoes to protect feet from the limestone rocks along the shoreline.
Check the official Travis County Parks website for current lake water levels before planning a boating trip.
Arrive early on summer weekends as the park reaches capacity quickly and may close to new arrivals.
Do not attempt to swim near the boat ramp or the active dam spillway due to heavy vessel traffic and underwater currents.
The park may close periodically during severe weather or high flood conditions on Lake Travis.
Leashed pets are permitted; glass containers are strictly prohibited within the park and shoreline areas.
