Sodom Dam, also known as East Branch Reservoir, is a masonry dam located in Brewster, New York, along the East Branch Croton River.
Completed in 1892, this dam serves as a critical water supply source for the area, with a storage capacity of 19,000 acre-feet and a normal storage level of 16,100 acre-feet. The dam stands at a height of 78 feet and stretches 1,600 feet in length, with a spillway width of 500 feet to manage maximum discharges of up to 38,000 cubic feet per second.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, Sodom Dam is inspected biennially to ensure its structural integrity and overall condition. Despite being classified with a high hazard potential, the dam has been assessed as satisfactory in condition, with risk management measures in place to mitigate potential threats. With its long history of providing essential water resources to the region, Sodom Dam remains a vital piece of infrastructure that requires ongoing monitoring and maintenance to safeguard against any potential risks or emergencies.
