The Allagash Wilderness Waterway is a 92.5-mile protected corridor in Maine’s North Woods, extending from Aroostook County into Piscataquis County through a connected landscape of lakes, ponds, rivers, and streams, including much of the Allagash River. Long traveled by the Wolastoqiyik, it later became part of the fur trade and a contested borderland between rival powers and colonies. Logging spread through the region before United States control was confirmed by the Webster–Ashburton Treaty in 1842, and intensified again in 1926 under Édouard Lacroix. The waterway also became associated with Maine game warden Dave Jackson and remains valued for canoeing and other outdoor recreation.
