VILLAGE OF PIPE, Wis. — Crews have rescued five fishermen who were stranded on Lake Winnebago after a crack developed in the ice.

The Fond du Lac County sheriff's office says the anglers, ages 16 to 20, became stranded Sunday about a half-mile out from the Village of Pipe when the wind switched and opened the crack.

The fishermen were unable to cross the crack, which had opened to about 50 yards wide.

Rescuers were able to get the fishermen and their gear to safety.

The sheriff's office says what may appear to be solid, stable ice can open up depending on wind directions.
