Built in 1928, this state-owned structure serves primarily as a hydroelectric facility, with a secondary purpose of navigation. Standing at 35 feet tall and stretching 900 feet in length, the dam has a storage capacity of 3,927 acre-feet and can discharge a maximum of 32,500 cubic feet per second.
Managed by the Federal Energy Regulatory Commission, High Dam poses a high hazard potential due to its location and design. Despite its age, the dam has been inspected regularly, with the last inspection conducted in September 2020. An emergency action plan has been prepared and revised, ensuring that the surrounding area is prepared for any potential risks associated with the dam.
With a moderate risk assessment rating, High Dam remains a key feature in the water resource management of the area. Its historical significance and continued function as a hydroelectric facility make it a valuable asset for both energy production and waterway navigation in the region.
