Mayhew Lake is a small carry-in lake. It lies in the headwaters of the Rainy River draining to that system via Loon, Crab and Gunflint Lakes to the Granite River. Mayhew Lake is managed primarily for lake trout. Rainbow trout are now being stocked into the lake as well. Northern pike, perch and bluegill round out the fishery.
