Moosehead Lake, lake, located in west-central Maine, U.S. Moosehead is the largest of the state’s many lakes, its waters covering an area of 120 square miles (310 square km). Lying at an elevation of 1,023 feet (312 metres), it is dotted with numerous islands, the largest of which is Sugar Island. The lake is the source of the Kennebec River. Moosehead’s irregularly shaped shoreline features numerous sheltered coves for fishing and recreation; Greenville, on its southern end, is a summer resort, outfitting centre, and seaplane station. The lake, when viewed from Mount Kineo on its east-central shore, supposedly resembles the head of a moose or a crouching moose.
