About Big Sand Watershed Structure Y-32-07 Dam

The primary purpose of Big Sand Watershed Structure Y-32-07 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 local government-owned.

The dam stands 33 feet tall, has a maximum storage capacity of 734 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1965, 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 unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 04/07/2022.

At 33 feet, this dam is taller than 76% of dams nationwide.
