Standing at a height of 10 feet and stretching 165 feet in length, the dam has a storage capacity of 504 acre-feet, serving a drainage area of 864 square miles.
Managed by the New York State Department of Environmental Conservation, the Movable Dam at Mays Point has a controlled spillway with a width of 120 feet, ensuring effective water flow regulation during periods of high discharge. Despite a low hazard potential, the dam is rated for a very high risk due to its age and potential for structural issues.
