The dam is designed to handle a maximum discharge of 3,900 cubic feet per second, although specific spillway details are not provided. In case of emergencies, an Emergency Action Plan is expected to be in place, although details regarding its preparation and compliance with guidelines are currently unavailable.
Overall, Lake Mohawk Dam functions as a vital structure for recreational activities in the region, while also serving as a critical component for water resource management along the Wallkill River. With its historical significance dating back to the early 20th century, the dam continues to be monitored and inspected to ensure public safety and environmental protection in the event of any unforeseen emergencies.
