Southwestern Montana

The best chances for good still water fishing here is the gulper activity of which that on Hebgen Lake is the most renowned. Comparable hatches happen on other regional still waters, and many of those have fewer fly-fishing attendees. Elk, Hidden, Quake, and Wade Lakes are good examples where fewer fly-fishers means more unattended waters to enjoy.
