Victor Braunig Lake, formerly known as East Lake, is a reservoir on Calaveras Creek and Chupaderas Creek 17 miles (27 kilometers) south of Downtown San Antonio, Texas, USA. The reservoir was formed in 1962 by the construction of a dam to provide a cooling pond for a power plant to supply additional electrical supply to the city of San Antonio. The dam and lake are managed by CPS Energy of San Antonio. Together with Calaveras Lake, Braunig 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.
