Montana river guides say it's too soon to know how this rafting and fishing season will shape up, but they do have some concerns about the lower snowpack last winter. Guides in southwestern Montana and in Glacier National Park say water levels will depend on spring and summer precipitation, and they'll adjust their strategies throughout the season. Comments from Joe Aanes (Ayns), fly fishing guide and independent contractor; and Hilary Hutcheson, outfitter, Glacier Raft Company and Glacier Anglers.
