Twin Buttes Reservoir was established to provide flood control, irrigation, water conservation, and a primary drinking water source for San Angelo and the surrounding communities in Tom Green County. The lake also serves as a recreational venue for fishing, boating, and swimming. The dam and reservoir are owned by the United States Bureau of Reclamation, and are managed by the City of San Angelo.
Twin Buttes Reservoir is an artificial lake located about 6 miles southwest of the city of San Angelo, Texas, and immediately upstream from Lake Nasworthy. With the financial support of the Upper Colorado River Authority, construction on Twin Buttes Dam to form the reservoir was completed in 1963. The dam is an unusual one – it dams the Middle and South Concho Rivers separately; a stabilization channel runs between the two sides of the lake. Water levels fell significantly during the 2010–13 Southern United States drought and remained low into 2014, standing at 20 percent of capacity on June 24, 2014.
