This earth-type dam serves a primary purpose of water supply, with a storage capacity of 230 acre-feet and a normal storage of 168 acre-feet. The dam, spanning 2800 feet in length and reaching a height of 20 feet, regulates the flow of the Mohawk River and covers a surface area of 10 acres.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, the dam has a high hazard potential but is currently in satisfactory condition. Its spillway, with a controlled design and a width of 4 feet, can handle a maximum discharge of 16 cubic feet per second. With a risk assessment rating of "Very High (1)", the dam is subject to regular inspections to ensure its structural integrity and the safety of the surrounding area.
For water resource and climate enthusiasts, the Cohoes Reservoir #3 Dam serves as a vital infrastructure supporting the water supply needs of the community while also posing challenges in terms of risk management and emergency preparedness. As a historic landmark with a significant impact on the local ecosystem, this dam embodies the intersection of human ingenuity and environmental stewardship in the face of changing climate patterns and water resource management practices.
