Sebasticook River

The Sebasticook River is a 76-mile-long river in the central part of Maine, in the United States. From its source in Dexter, the upper "Main Stream" section flows generally west and south 30 miles to Great Moose Lake. From the outlet of the lake in Hartland, the Sebasticook flows 41 miles south to the Kennebec River in Winslow.
The Sebasticook River is the largest tributary to the Kennebec and thus plays an important role in the restoration of both the anadromous and resident aquatic fisheries of the Kennebec basin and the Gulf of Maine ecosystem. Due to its relatively close proximity to the lower Kennebec, large drainage area, and low gradient, this watershed historically contributed a major percentage of available spawning and nursery habitat for anadromous runs of alewife, blueback herring, American shad, rainbow smelt, and striped bass associated with the Kennebec River watershed and Gulf of Maine ecosystems. To a lesser extent, the river provided habitat for Atlantic salmon.
