Fond Du Lac in Duluth, Minnesota, is a hydroelectric dam that has been serving as a vital water resource facility since its completion in 1924. With a dam height of 80 feet and a hydraulic height of 73 feet, Fond Du Lac stands as a key structure on the St. Louis River, with a storage capacity of 2,675 acre-feet and a maximum discharge of 181,000 cubic feet per second. The dam's primary purpose is hydroelectric power generation, and it is regulated by the Federal Energy Regulatory Commission.

Despite its age, Fond Du Lac remains a crucial component of the region's water management infrastructure, with a controlled spillway width of 480 feet and a surface area of 160 acres. The dam has a high hazard potential and a very high risk assessment rating, emphasizing the importance of regular inspections and maintenance. The facility is inspected annually by state regulatory agencies and the Federal Energy Regulatory Commission to ensure its structural integrity and compliance with safety standards.

Fond Du Lac's association with the St. Paul District of the US Army Corps of Engineers highlights its significance in the region's water resource management. The dam's impressive engineering features, such as arch, earth, and gravity dam types, contribute to its ability to provide reliable hydroelectric power and water storage for the surrounding area. As climate change continues to impact water resources, facilities like Fond Du Lac play a critical role in ensuring water security and resilience in the face of changing environmental conditions.
