About Flagstaff Lake

Flagstaff Lake is the largest body of water in the state of Maine, offering a peaceful retreat for those seeking outdoor recreation amid scenic landscapes and abundant wildlife.

Wilderness Landscape & Natural Heritage

Flagstaff Lake, located in Northwestern Maine, is part of the Bigelow Preserve and serves as a major reservoir with both historical significance and recreational appeal. The area encompasses over 20,000 acres and was formed in the 1940s through the damming of the Dead River. Its surroundings feature a rich tapestry of forests and mountainous terrain, highlighted by the Bigelow Mountain Range to the south. Popular activities include kayaking, canoeing, and fishing, as the lake is a habitat for brook trout and landlocked salmon. Furthermore, the region is steeped in history, with the submerged village of Flagstaff under its waters, providing a glimpse into the area’s past. Flagstaff Lake’s setting makes it a prime destination for those seeking solitude and nature activities, with the Appalachian Trail running close by, offering hiking and wildlife viewing opportunities. Its remote location ensures an intimate outdoor experience, away from the hustle and bustle of more frequented lakes.
