The Flathead Lake watershed includes most of Flathead County and then some.  Starting in Canada at the smallest tributaries (headwaters) of the North Fork, the Flathead Lake watershed includes all land that drains into the Stillwater, Whitefish, and Swan rivers; the North, Middle and South Forks of the Flathead, and Ashley Creek.  The City of Whitefish and many individual landowners derive their drinking water from these surface waters.
