Flathead Lake - Goose Island

The largest natural freshwater lake in the western U.S., Flathead Lake offers clear water with visibility often exceeding 100 feet and depths over 300 feet, drawing divers to its rock formations and underwater cliffs. Goose Island, a glacial rock outcropping ringed by boulders and fish, is a highlight, and several boats have been deliberately sunk to create fish habitat and dive attractions. Somers Bay on the north end holds the upside-down hull of the Kee-O-Mee, a 54-foot pleasure boat that sank in 1937, along with the remains of the old Somers Mill.
