Couderay River

Lac Courte Oreilles is the largest natural lake in Sawyer County and the 8th largest in the State. The lake is managed as a trophy muskie fishery and special limits apply; check the current regulations booklet for details The east portion of the lake is within the Lac Court Oreilles Indian Reservation.

A number of minnow species, including trout perch and lake shiners contribute to an ample forage base. Juvenile panfish, especially bluegill and perch, are also important. Cisco, redhorse and small sucker are abundant and responsible for the fast growth rates of adult gamefish. Crayfish and mayfly larvae add to the abundant forage base.

Surveys indicate extensive walleye movement into Whitefish Lake for spawning while smaller numbers annually spawn in Grindstone Lake. The major spawning area for muskie and northern pike has been Musky Bay. Gamefish species, especially muskie and walleye, move to deep water by July to prey on the cisco forage. Larger northern pike also seek the cooler water temperatures and deep water cisco by July.
