This concrete dam, standing at a height of 15 feet and spanning a length of 74 feet, holds a storage capacity of 365 acre-feet of water from the Sugar River. Despite its fair condition assessment and significant hazard potential, the dam is regularly inspected by NHDES DAM BUREAU to ensure its safety and integrity.
The dam features an uncontrolled spillway with a width of 32 feet, allowing for a maximum discharge of 3130 cubic feet per second. Its moderate risk assessment indicates a need for ongoing risk management measures. While the dam has a history of modifications and inspections, the emergency action plan and inundation maps are yet to be prepared, highlighting areas for improvement in emergency preparedness and response.
With its picturesque location and recreational value, Wendall Marsh Dam serves as not just a water resource structure but also a hub for outdoor activities in the region. As climate change continues to impact water resources, the ongoing monitoring and maintenance of this dam are crucial to ensure the safety of downstream communities and the preservation of the surrounding environment.
