Built in 1918, this concrete dam stands at a height of 16 feet and spans 75 feet in length, providing a storage capacity of 10,488 acre-feet. With a spillway width of 50 feet, the dam has a maximum discharge capacity of 764 cubic feet per second, ensuring efficient water management within the 1.6 square mile drainage area.
Operated and regulated by the New York State Department of Environmental Conservation (NYS DEC), Watsons Waste Weir Dam is designated as a low hazard potential structure with a moderate risk assessment rating. Despite being in moderate risk, the dam's condition remains unrated, and no emergency action plan (EAP) has been prepared. Regular inspections, the last conducted in November 2020, ensure continued safety and functionality of the dam for navigation purposes. With its historical significance and essential role in water resource management, Watsons Waste Weir Dam stands as a testament to the importance of sustainable infrastructure in mitigating climate impacts.
