The underwater world of Montana is as scenic as the rocky mountain peaks surrounding it. Glacier National Park, a vast wilderness preserve that passes into Canada has the largest lake: Lake McDonald. The lake is home to numerous native species of trout as well as other game fish. The lake also home to Lake Superior whitefish, mountain whitefish and kokanee salmon.
Canyon Ferry Lake is a reservoir 50 miles downstream from where the Gallatin, Madison, and Jefferson Rivers join to form the Missouri River. The reservoir hosts 76 miles of shoreline, and offers excellent diving opportunities. Rainbow trout, perch, ling, and walleye take up home here.
It is recommended to wear a full 5/7mm wetsuit during the summer in the lakes. If you dive in the spring or fall, most locals will opt for a dry suit. Ice diving is possible in some of the lakes.
No matter what time of year you visit Montana, excellent visibility and amazing underwater vistas are ready and waiting.
