About Sinclair Ridge Storm Pond
The primary purpose of Sinclair Ridge Storm Pond 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 Century Communities (private).
The dam stands 15 feet tall and stretches 400 feet across, has a maximum storage capacity of 25 acre-feet, and collects water from a drainage area of 50 square miles. Completed in 2024, the structure is relatively new.
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. Notably, no emergency action plan is currently on file for this high-hazard dam.
