Over 100 fishermen were rescued Friday evening after an ice floe detached in a northern Minnesota lake, according to police.

The Beltrami County Sheriff’s Office said 122 fishermen were stranded when the ice floe detached from the main shoreline on Upper Red Lake.

According to the Minnesota Department of Natural Resources, Upper Red Lake is the largest of all inland lakes in Minnesota.

Thirty feet of open water separated the ice floe from the shore, according to the sheriff’s press release.

Before emergency responders arrived on the scene, a bystander attempted to assist with evacuations by a canoe.

During the rescue attempt, four people fell into the water but they were safely brought back onto the floating ice and warmed in a fishing shelter, according to police.

Those four were the first to be rescued.
