Overview of Location

Flathead Lake is the largest body of natural fresh water that exists west of the Continental Divide. It’s almost 28 miles long and 15 miles wide, has a 160-mile shoreline and covers more than 120,000 acres. The Flathead and Swan Rivers flow into this lake that was created by glaciers of the Ice Age.

Type of waterway

Fishing Flathead Lake is best done by boat. Most of the lake’s fish live deep in the cooler waters, and trolling gear should be used. In September, the fish will come to the shoreline and a fisherman can conceivably wade fish, but reaching the spots with steep slopes and drop-offs with a boat is still more effective.

Fishing seasons

You’ll find the fall is the best time for Flathead Lake, Montana fishing. In September the fish swim up to the shoreline and you can make a large catch. The rest of the year you’ll need to get out in a boat with trolling gear to catch the fish that prefer the cooler waters deep in the lake.

Most common fish species

Flathead Lake is home to many species of trout, such as rainbow, cutthroat, brown, brook, golden, bull and lake trout. The Lake or Mackinaw trout can reach monster sizes of over twenty pounds. You’ll also find Kokanee salmon, whitefish, northern pike, yellow perch, largemouth and smallmouth bass.

Directions for access

Flathead Lake lies between US Highway 93 and Route 35, southwest of Glacier National Park. Polson, Montana is at the southern-most tip of the lake.
