The Story of Flagstaff Lake

Flagstaff Lake is the 4th largest lake in the State of Maine, is a 20,300-acre lake that captures runoff from 520 square miles of the Upper Dead River Watershed. The completion of the Long Falls Dam in 1950 established Flagstaff Lake’s importance for regulating water flow into the Kennebec River Basin.

Today your time on Flagstaff Lake can be spent pontoon boating, going swimming, fishing, kayaking or canoeing, stand up paddle boarding or camping on one of the many islands campsites.

Tenting is available free of charge at the Round Barn campsites on the shore of Flagstaff Lake. These sites are accessible by water or by a short trail originating from the vehicle parking lot. They have fire rings and pit toilets.

From the Round Barn parking area, the trail leads easterly along the shore to a half dozen secluded single party campsites. To the west is a large group site that can accommodate up to 30 people.

A nearby day-use area on the shore of Flagstaff Lake offers swimming and picnicking. A hand-carry boat or canoe may be launched from the beach.

Flagstaff Lake is part of the Northern Forest Canoe Trail. The Northern Forest Canoe Trail is a historic 740-mile water-trail through New York, Vermont, Quebec, New Hampshire, and Maine.
