Old Forge Reservoir Dam, located in Old Forge, New York, is a concrete structure completed in 1905 to primarily reduce flood risks in the area. Managed by the state agency NYS DEC, this dam spans 129 feet in length and stands at a height of 18 feet, holding a maximum storage capacity of 22,610 acre-feet. Despite its age, the dam has a normal storage capacity of 9,002 acre-feet and covers a surface area of 736 acres, serving as a crucial asset for flood control and recreation purposes.

The dam's spillway, with a width of 36 feet, is controlled to manage maximum discharge of up to 980 cubic feet per second, ensuring the safety of downstream areas. However, with a significant hazard potential and a poor condition assessment in 2017, the dam's risk level is categorized as "Very High (1)", necessitating regular inspections and maintenance. Although the dam's Emergency Action Plan (EAP) status and risk management measures are unclear, its strategic location on the Middle Branch Moose River underscores its importance in safeguarding the surrounding Herkimer County and New York communities from potential flooding events.

Water resource and climate enthusiasts can appreciate the historical significance and functional aspects of Old Forge Reservoir Dam, recognizing its vital role in flood risk reduction and recreational activities. As one of the key infrastructure elements in the region, this concrete dam continues to be monitored and inspected regularly to ensure public safety and environmental resilience against the impacts of extreme weather events and climate change.
