New Flathead River Maps


New maps showing the channel migration zone and the depth and velocity of the Flathead River above the lake are now available.  These maps will be useful for land owners, planners and others who make decisions that could be affected by river movement. The Channel Migration Zone Report includes information about channel migration and erosion, geomorphology, hydrology, study methods and results, photos, and maps.
