This private dam, standing at a height of 16 feet and stretching 275 feet in length, holds a maximum storage capacity of 85 acre-feet with normal storage at 69 acre-feet. However, recent data indicates a poor condition assessment and significant hazard potential, raising concerns for the dam's structural integrity and safety.
Managed by the NYS DEC, the dam overlooks the TR-Hudson River and is regulated, permitted, inspected, and enforced by state authorities. Despite its recreational significance, the dam's risk assessment is moderate, emphasizing the need for improved risk management measures to mitigate potential hazards. With a spillway width of 30 feet and uncontrolled spillway type, Lake Boyce Dam's last inspection in 2017 revealed a concerning condition, underscoring the importance of ongoing maintenance and safety protocols to ensure public and environmental safety around this water resource.
Water resource and climate enthusiasts visiting Lake Boyce Dam can appreciate its historical significance and natural beauty while recognizing the importance of ongoing monitoring and maintenance efforts to safeguard against potential risks and ensure the sustainable enjoyment of this recreational site along the Hudson River.
