Flathead River, Main Stem

Flathead River, Main Stem Professional Review and Guide

"The main stem of the Flathead begins at Blankenship Bridge where the North Fork and Middle Fork of the Flathead come together. The South Fork of the Flathead joins shortly downstream to complete the triad. The massive river drains most of Glacier National Park, the Bob Marshall Wilderness, and the Flathead National Forest.

The Flathead River flows for nearly 160 miles and eventually dumps into the Clark Fork River near Paradise. The river is distinctly divided into two sections separated by Flathead Lake—the largest natural lake west of the Mississippi.

Types of Fish: Rainbow, Westslope Cutthroat, Bull, Brown and Lake Trout, Northern Pike, Smallmouth Bass, Whitefish."
