About Big Sand Watershed Structure Y-32-10 Dam
The primary purpose of Big Sand Watershed Structure Y-32-10 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 Scott Lovelace (local government). It impounds the Thompsom Creek near North Carrollton Town Center.
The dam stands 47 feet tall and stretches 1,660 feet across, creates a reservoir covering 124 acres, has a maximum storage capacity of 2,650 acre-feet, and collects water from a drainage area of 13 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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 04/15/2022.
At 47 feet, this dam is taller than 92% of dams nationwide.
