"Androscoggin Watershed" state map

The Androscoggin begins in northwestern Maine at Umbagog Lake, journeys through New Hampshire, then re-enters Maine near Bethel, eventually joining the Kennebec at Merrymeeting Bay.

While the Penobscot was primarily a logging river and the Kennebec a transportation corridor, the Androscoggin has traditionally been Maine's principal industrial river. Thanks to a 1000 foot drop from its headwaters to the sea, the Androscoggin has an average descent of 8 feet per mile--a swift flowing, large volume river provides an excellent power source.

Consequently, the Androscoggin has borne a heavy burden of pollution. The Maine DEP, communities, and industries have begun collaborating to improve the river, and the results so far have been promising.
