The poor condition of the dam that holds in the waters of Austin’s beloved Lady Bird Lake continues to vex city officials. Emails obtained in a public information request reveal challenges the city faced in performing maintenance on Longhorn Dam, which crosses the Colorado River beneath Pleasant Valley Road. Documents tell of water lost through the dam’s gates that could potentially stay in upstream reservoirs, and show city departments struggling to assign responsibility for the structure and plan a long-term solution.
Austin Energy, the city-owned electric utility, and the Lower Colorado River Authority (LCRA) have long known about the need for work on the dam. Austin Energy is the city department that operates the structure. The LCRA operates dams upstream from Austin and coordinates with Austin Energy when they release water downstream.
