CODY, Wyo. (AP) — Authorities say two fathers and four daughters have survived after they were tossed into the chilly waters of Buffalo Bill Reservoir when their boat capsized in a storm.

Park County Sheriff's Office says it received the report of the six in the reservoir near Cody about 6:30 p.m. Saturday.

A storm developed and they were headed in, but 3-foot swells capsized the boat about 1,000 feet from shore.

But before rescuers could launch their craft, officials say another boater rescued one of the men and the four juvenile girls, while the other man made it to shore using a picnic cooler as a float.

The victims were treated for hypothermia at the scene by ambulance crews. There was no further word on their conditions.
