Ice Jam Triggers Flooding on Montana's Tongue River

The National Weather Service issued a flood warning on Wednesday, March 20, after an ice jam accumulated on the Tongue river near Twelve Mile Dam, south of Miles City, in Montana.

Video posted by a local Montana Fish and Wildlife office shows water rushing over the dam, sweeping large chunks of ice downstream.

Water levels in the Tongue river reached nearly 11 feet, above the river’s flood stage, by Wednesday night. Credit: Montana Fish, Wildlife & Parks – Region 7 via Storyful
