High-Water Mark Sign to Commemorate Historic Flathead Flood

By Beacon Staff

A new sign commemorating the largest flood in 100 years in the Flathead Valley will be unveiled along the Flathead River in Columbia Falls Thursday, June 7. The event begins at 1 p.m. on South Nucleus Ave. next to the river.

The National Weather Service and U. S. Geological Survey are hosting the ceremony for the 1964 flood on the Flathead River. A new high-water mark sign is being placed along the Flathead River. Personnel from Flathead County, the City of Columbia Falls, the Geological Survey and the Weather Service will be in attendance.

On June 7, 1964, rain began falling in the mountains along the Continental Divide just 30 miles east of the new high-water mark sign. After a day and a half of rain, some of the mountain locations received between 10 and 14 inches of rain. Two days later, the site of the new sign was completely under water.
