About Rowlett Creek Ws Scs Site 12 Dam
The primary purpose of Rowlett Creek Ws Scs Site 12 Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Dalworth Swcd (local government). It impounds the Tr-lake Ray Hubbard.
The dam stands 32 feet tall and stretches 1,230 feet across, creates a reservoir covering 21 acres, has a maximum storage capacity of 773 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1955, 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 11/07/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
