The list of flies that will catch fish in and around Glacier National Park is as varied as the conditions and seasons that you'll be likely to encounter on your search for trophy trout. Steve Thompson, owner of LakeStream Fly Shop in Whitefish, Montana, says that with these ten flies, you should be able to catch fish whether you fish in a river, creek or lake.
