The US Forest Service manages the Knutson Dam, and the other is operated by the Otter Tail Power Company which is located just below Stump Lake. Cass Lake is different than most of the other walleyes lakes in the area in that fishing can vary from a few feet of water to water as deep as 70 feet. Cass Lake is also made up of multiple lakes with in a lake. Several shallow flats separate one deep hole from another.
The scenery is incredible on the lake with 27 miles of forested shoreline and sandy beaches and plunging to 120 feet deep in areas. Many tourists visit Star Island yearly for its hiking trails, campgrounds and picnic facilities. Star Island is unique in the fact that it is the only island in Minnesota that contains its own lake, Lake Windigo.
This lake always ends up on someone’s list of great fishing places in Minnesota. Cass Lake offers fine populations of walleye, northern pike, perch, and is also coveted by muskie anglers. Cass Lake is a “walleye factory” and offers top notch walleye that would rival any lake in Minnesota. Muskies also provide a great fishery and Cass Lake is second only to Leech Lake in the number of muskies caught annually. Many of these trophies exceed the 40-pound mark. Whether you are after that one trophy muskie or a mess of perch, or great tasting walleye action, Cass Lake’s maze of steep drop-offs, mid-lake bars, rock piles and sunken islands are sure to be holding just what you are looking for.
