NEW ORLEANS — A Coast Guard helicopter rescued three people and a dog from the marsh after their boat sank Saturday afternoon near Goose Point on the north shore of Lake Pontchartrain, according to a news release.

The Coast Guard received a call at 1 p.m. about the sinking boat in Lake Pontchartrain from the St. Tammany Parish Sheriff’s Office, which had sent three boats to aid in search, the release says.

A Coast Guard Air Station New Orleans MH-65 Dolphin helicopter crew training in the area arrived about two hours after the initial call and deployed its rescue swimmer, who guided one of the searching boats to the shore where the survivors stood, some 10 feet from their overturned boat, the release says. Once on the Sheriff’s Office boat, the survivors were hoisted into the helicopter and found not to require medical attention, the release says.

Petty Officer 2nd Class Nicholas Gardner said in the release that hypothermia had not set in because the hunters were wearing proper winter clothing.
