The dam and lake are managed by CPS Energy of San Antonio. Together with the smaller Victor Braunig Lake, Calaveras Lake was one of the first projects in the nation to use treated wastewater for power plant cooling. The reservoir is partly filled with wastewater that has undergone both primary and secondary treatment at a San Antonio Water System treatment plant. Calaveras Lake also serves as a venue for recreation, including fishing and boating. Sailboats are prohibited on the lake.

Calaveras Lake has been stocked with many species of fish for recreational fishing. Fish present in Calaveras Lake include red drum, hybrid striped bass, catfish, largemouth bass.

Thousand Trails Management Services operates the 147 acre (57 ha) public facility under contract with CPS Energy at the lake. The lake features facilities for camping, picknicking, fishing, boating, and hiking.
