Minnesota Power has 11 hydroelectric generating stations and 17 reservoirs in northern Minnesota. Many of these reservoirs were created in the late 19th century by logging companies to transport cut logs; they encompass several thousand acres of land and water along major river networks, including the St. Louis, Whiteface, Cloquet, Kawishiwi, Crow Wing, Gull and Mississippi.

The reservoir system is a major recreation resource and Minnesota Power encourages its use by maintaining picnic areas, fishing access points, boat launches, canoe portages, recreation trails and camping sites.

Recreation areas include Whiteface Reservoir, Fish Lake Reservoir, Wild Rice Lake Reservoir, Island Lake Reservoir and Boulder Lake Reservoir.
