Completed in 1900, this dam stands at a height of 9 feet with a hydraulic height of 6 feet, providing storage of 1590 acre-feet and covering a surface area of 403 acres. The dam regulates Mud Mills Stream and is under the jurisdiction of the Maine Emergency Management Agency, ensuring it meets state regulations for permitting, inspection, and enforcement.
Despite its historical significance and multifaceted utility, Cochnewagon's condition assessment is deemed unsatisfactory, with a significant hazard potential. The last inspection in July 2018 revealed the need for improvements, as the dam falls short of safety standards. The emergency action plan (EAP) for Cochnewagon was last revised in October 2020, indicating ongoing efforts to address potential risks and ensure the safety of the surrounding area in the event of an emergency. Climate and water resource enthusiasts are urged to monitor updates on Cochnewagon's risk management measures and improvements to safeguard this vital infrastructure and the community it serves.
