The lake serves as a cooling reservoir for the Braunig Power Station, keeping water temperatures higher than natural local lakes.
The Texas Parks and Wildlife Department stocks the lake specifically with red drum, a saltwater species that thrives here due to the unique water conditions.
Blue catfish in the lake have been recorded at weights exceeding 50 pounds.
The park was created as part of a utility-managed land reclamation and recreation project.
Despite being a reservoir, the salinity levels are low, yet it successfully hosts saltwater fish species.
The location is a recognized hotspot for winter bird watching due to the lake remaining ice-free and warm.
Braunig Lake Park is a 1,350-acre reservoir located south of San Antonio, managed by CPS Energy primarily as a cooling pond for the nearby power plant. The lake is well-known for its warm water temperatures, which allow for a thriving population of non-native trophy fish species. It is a premier destination for anglers targeting trophy-sized blue catfish, red drum, and hybrid striped bass. The park offers shoreline access for fishing, concrete boat ramps for watercraft, and designated areas for primitive and RV camping. Birding enthusiasts frequently visit to observe migratory species and resident waterfowl along the shoreline. The site features various picnic areas equipped with tables and grills. Public access is provided through a gated entry that requires a fee for entry and boat launching. The park’s unique ecosystem is maintained by the circulation of cooling water from the power plant, which keeps the lake warmer than neighboring water bodies during winter months.

Bring polarized sunglasses to better spot fish and navigate the shoreline.
Check the wind forecast before heading out, as large open reservoirs can develop choppy conditions quickly.
Ensure you have a valid Texas fishing license, as park rangers frequently verify compliance.
Do not attempt to fish near the intake or discharge structures of the power plant, as these areas are restricted for safety.
Park hours vary seasonally; typically closed on specific holidays or during inclement weather events.
Catch and release is encouraged for trophy-sized fish; pack out all trash to maintain the water quality.
