Island Lake North Dike, located in St. Louis County, Minnesota, is a crucial structure regulating the flow of the Cloquet River. This dam was completed in 1915 and serves primarily for hydroelectric power generation, as well as recreation. With a height of 21 feet and a length of 1100 feet, the dam has a storage capacity of 177,000 acre-feet and a surface area of 10,800 acres, making it a significant water resource in the region.

The dam is regulated by the Minnesota Department of Natural Resources and inspected by the Federal Energy Regulatory Commission, ensuring its safe operation and compliance with environmental regulations. Despite its high hazard potential, the condition assessment of the dam is currently not available. With a maximum discharge of 7,445 cubic feet per second, the Island Lake North Dike plays a critical role in managing water levels and protecting downstream areas from flooding.

As climate change continues to impact water resources and hydroelectric infrastructure, the Island Lake North Dike remains a key component in the region's water management system. With its historical significance and ongoing importance for both energy production and recreational activities, this dam serves as a vital link between water resource management and climate resilience in Minnesota.
