Built in 1926, this earth dam stands at a height of 20 feet and spans 260 feet in length, with a storage capacity of 52 acre-feet. The dam is situated on Deuel Hollow Brook, a tributary that covers a drainage area of 4.68 square miles, providing a surface area of 4 acres for recreational activities.
Managed by a private owner, Camp Siwanoy Dam is regulated by the New York State Department of Environmental Conservation (NYS DEC), ensuring its compliance with state inspection and enforcement protocols. Despite being rated with a low hazard potential and a lack of current condition assessment, the dam's Emergency Action Plan (EAP) was last revised in 2010, indicating a need for updated risk management measures. While the dam's primary purpose remains for recreation, its role in water resource management and the conservation of Deuel Hollow Brook underscores its importance in balancing environmental stewardship and public enjoyment.
