Sixty years ago the waters rose and rose until they became the largest flood in Flathead County’s recorded history.

When torrential rains poured on top of a heavy mountain snowpack on June 8-9 of 1964, it caused, by some measures, one of the most powerful flash floods in the United States.

Water poured down both sides of the Continental Divide, tearing out roadways and rail lines and ripping away bridges. Three dams failed. Another was over-topped. At least 28 people died and more than 2,200 homes and buildings were damaged or destroyed in seven counties and a dozen communities in Montana.
