Flathead Lake is the largest body of natural water found west of the Continental Divide. It is a beautiful lake, surrounded by the tall and impressive Mission Mountains on the east and the smaller Salish Mountains to the west.
The broad Flathead Valley stretches off on the north and south sides of the lake. The town of Polson sits on the south shore of the lake, while the popular and artsy town of Bigfork lies on the northeast corner.
Flathead Lake is very popular for pleasure boaters. Due to the size and beauty of the lake, sailboats are common on the lake, along with pleasure boats of all kinds. The lake itself is ringed by vacation homes of increasing size and elegance, as more and more individuals from outside Montana build exotic homes on the lake.
The lake itself offers excellent fishing, but not necessarily for fly fishing. The fish species in the lake consist primarily of lake trout, pike, yellow perch, and whitefish, with some rainbow trout, bass, kokanee salmon, and bull trout also found. The lake trout in Flathead Lake can reach monstrous sizes, frequently exceeding twenty-pounds. An average lake trout is considered to be in the three to the eight-pound range and is caught frequently.
