The Allagash River is an approximately 105 km long right tributary of the Saint John River in the northwest of the US state Maine .
It drains a remote and scenic area in the Maine North Woods north of Mount Katahdin .
The name "Allagash" is derived from the Penobscot word / walakéskʸihtəkʸ / and means "bark stream".
The Allagash River forms the drain of Churchill Lake (formerly known as Heron Lake ) at Churchill Depot in northern Piscataquis County .
Originally, the Allagash River also drained the following lakes: Allagash Lake , Chamberlain Lake, and Telos Lake . In the 1840s, however, several dams were built, so that the water from these lakes has drained to the East Branch Penobscot River ever since . The purpose of this derivation was the rafting of tree trunks to the southern coast of Maine.
The Allagash River flows mostly in a northeast direction. He passes a chain of natural mountain lakes. Eventually it meets the Saint John River near Allagash near the international border with New Brunswick (Canada).
The relatively natural course of the Allagash River is an attractive destination for canoeists .
In 1857 Henry David Thoreau went on a canoe trip to the source of the Allagash River, Heron Lake, with his Concord friend Edward S. Hoar and the Penobscot guide Joseph Polis .
His voyage notes, known as "The Allagash and East Branch", were published posthumously as the third chapter of The Maine Woods in 1864.
In 1966, Maine residents voted to preserve and protect the river. Much of the stretch of the river is now in the Allagash Wilderness Waterway . In 1970 this waterway became part of the National Wild and Scenic River program. In the 1990s, Churchill Dam, built with wood, was replaced by a concrete dam. This led to criticism from environmental activists. Recreational use and conservation of the river system remain a controversial topic.
The US government operates a gauge 5 km above the river mouth. The mean discharge of the Allagash River measured there is 56 m³ / s.
