Flathead Lake – A Western Montana Gem

Flathead Lake is not only the largest lake in the state of Montana, but it is also the largest lake in the western part of the United States. It is even larger than Lake Tahoe found in Nevada. Flathead Lake stretches about 27.3 miles from north to south and is about 15.5 miles wide at its widest point. It was created when the Flathead River was partially dammed by a moraine and silt at the end of the last ice age. Today this lake continues to be fed by the Swan River, and it is fed and drained by the Flathead River. With an average depth of 164.7 feet, and a surface area of over 191 square miles, Flathead Lake a vacationer’s paradise.


One of the most popular activities to do on Flathead Lake is to fish. The lake is stocked annually with a variety of fish that are perfect for anglers of all fishing skill levels. Dock fishing is a great activity for kids. This is because smaller fish like minnows and perch love to school around the protection of local docks and boat houses.

On the other hand, if you are interested in fish that put up more of a fight, then you will want to hit the open waters of the lake where you can find cutthroat trout, brook trout, lake trout, Northern pike, brown trout, golden trout, kokanee salmon, large mouth bass, small mouth bass, rainbow trout, bull trout, and whitefish. Also keep your eye open for the Flathead Lake Monster!


Boating is another very popular activity to do on Flathead Lake. Pontoon boats work well for fishing adventures on this lake, as do smaller vessels. Fortunately, you can rent and/or launch boats at any of the local marinas. The local marinas include the Arrowhead RV Park and Marina found 15 miles north of Polson, Big Arm Marina found 12 miles north of Polson, Bigfork Marina and Boat Center found in the Northeast corner of the lake and the Marina Cay Resort found at Bigfork Bay. If you have your own boat you can launch it at nearly any lake access park.
