Standing at a height of 10 feet and spanning 40 feet in length, the dam impounds Punch Brook, providing a storage capacity of 6 acre-feet with a maximum discharge of 2788 cubic feet per second. The dam's spillway, of uncontrolled type, is 30 feet wide, contributing to its significant hazard potential.
Managed by a private owner, Mill Pond Dam is regulated by the New York State Department of Environmental Conservation (NYS DEC), with state jurisdiction, permitting, inspection, and enforcement in place. Despite its age, the dam's condition assessment remains unrated, and its emergency action plan was last revised in 2011. The risk assessment for this dam is moderate (3), indicating a level of risk that requires attention and management. With its rich history and continued importance for water resource management and recreation, Mill Pond Dam stands as a significant landmark in Columbia County, New York, deserving of ongoing monitoring and maintenance to ensure public safety and environmental protection.
