Island Lake, located in Cloquet, Minnesota, is a significant hydroelectric and recreational resource along the Cloquet River. Constructed in 1915, the dam stands at a height of 57 feet and has a hydraulic height of 36 feet, with a storage capacity of 177,000 acre-feet. The dam's primary purpose is hydroelectric power generation, but it also serves as a recreational area, offering opportunities for outdoor activities in its vast surface area of 10,800 acres.

Managed by the Federal Energy Regulatory Commission, Island Lake Dam has a controlled spillway with a width of 40 feet and a high hazard potential, necessitating regular inspections to ensure its safety. The dam's structure, consisting of concrete, earth, and gravity elements, spans 880 feet and has a maximum discharge capacity of 7,445 cubic feet per second. With its close proximity to the city and its critical role in water resource management, Island Lake Dam remains a vital asset for the region, providing both energy production and recreational enjoyment for visitors.

Despite its age, Island Lake Dam continues to be a key player in the region's water resource infrastructure, with its high risk potential requiring ongoing risk management measures. The dam's association with the Cloquet River and its significant storage capacity make it a crucial component of the local ecosystem and water management system. As a focal point for both hydroelectric power generation and recreational activities, Island Lake Dam stands as a testament to the importance of sustainable water resource management and climate resilience in the face of evolving environmental challenges.
