Stonebrook Farm Subdivision Lake Dam

About Stonebrook Farm Subdivision Lake Dam

The primary purpose of Stonebrook Farm Subdivision Lake 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 Sf Homeowners Association Inc;stonebrook Farm Homeowners Association (private). It impounds the Tr-rocky Creek.

The dam stands 26 feet tall, creates a reservoir covering 9 acres, and has a maximum storage capacity of 150 acre-feet. Completed in 1939, the structure is well-established, with more than 75 years of service.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 05/16/2023.
