About Beaver Brook Site #1 Dam
The primary purpose of Beaver Brook Site #1 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 Town Of Manheim (local government). It impounds the Beaver Brook near Dolgeville.

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 01/30/2024.
At 36 feet, this dam is taller than 83% of dams nationwide.
