Built in 1983, this earth dam stands at 18 feet tall and stretches 250 feet in length, providing storage for up to 60 acre-feet of water. With a normal storage capacity of 42 acre-feet and a drainage area of 2.84 square miles, the dam plays a crucial role in regulating the flow of the TR-LONG ISLAND SOUND river or stream.
Despite its low hazard potential, Mill Pond Dam is subject to state regulations, inspections, and enforcement by the NYS DEC. While the condition of the dam is currently unrated, it has a moderate risk assessment score of 3. The spillway, with a width of 32 feet, is uncontrolled, allowing for a maximum discharge of 688 cubic feet per second. Although last inspected in 1983, the dam's emergency action plan status, inundation maps, and risk management measures are not documented, highlighting potential areas for improvement in the future.
Overall, Mill Pond Dam stands as a vital infrastructure component in the water resource management system of Nassau County, New York. Its strategic location and design contribute to flood control, water storage, and environmental preservation efforts in the region. As water resource and climate enthusiasts, a closer examination of this dam can provide valuable insights into the intersection of infrastructure, regulation, and risk management in safeguarding our natural resources.
