About Decker Creek Dam
The primary purpose of Decker Creek Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Austin (local government). It impounds the Decker Creek.
The dam stands 83 feet tall and stretches 6,390 feet across, creates a reservoir covering 1,269 acres, has a maximum storage capacity of 45,200 acre-feet, and collects water from a drainage area of 9 square miles. Completed in 1967, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 08/06/2014. That was 11 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 83 feet, this dam is taller than 97% of all dams in the United States.
