The Gallatin County Sheriff's Office says an ice dam broke loose on the Gallatin River Friday afternoon trapping a fisherman.
According to the sheriff's office, search and rescue received the call right around 5:00 p.m.
Officials say, "the flooding ice and water created a new channel in the river that effectively left the fisherman stranded on an island. The fisherman could not cross the fast flowing water and debris to safety."
Safety lines and flotation gear were thrown to the man, who was able to secure himself and wade through the river.
NBC Montana viewer David Ris sent us video of the break up he captured as it happened.
He tells us he took the video of the water rushing down the channel around 3:15 p.m. two miles south of Big Sky, down from the Red Canyon Campground.
According to Ris the three to four foot rush of water snapped trees and bushes in the path of the ice.
The Gallatin County Sheriff's Office says it did receive several reports of rising river levels down stream, but no reports of damage.
