The Canyon Dam in Texas is a rolled-earth dam on the Guadalupe River in the Hill Country. The water impounded by the dam forms Canyon Lake.To visit Canyon Dam on your holiday in Canyon Lake, and find out what else Canyon Lake has to offer, use our Canyon Lake.
The dam is located 36 miles northeast of San Antonio and 38 miles southwest of Austin.
The dam is 6,830 feet long, across a narrow section of the Guadalupe River valley. The top of the dam is 974 feet above sea level, or 224 feet above the riverbed. A spillway, located south of the dam, protects the dam by releasing water when the lake level rises to 943 feet above sea level.
The dam is located near the Balcones Escarpment. The rocky canyons to the west of the escarpment can carry more water than the riverbeds of the plains to the east; this has caused problems with flash flooding in cities and towns east of the escarpment.
After major floods on the Guadalupe River in 1936 and 1938, state and community leaders pressured the federal government to help control flooding of the river. Congress authorized initial funds for construction of a dam in the Rivers and Harbors Act of 1945; final construction approval came in the Flood Control Act of 1954.
