The Middle Branch of the Little Magalloway River is a 4.6adj=midNaNadj=mid river in northern New Hampshire and northwestern Maine in the United States.[1] It is a tributary of the Little Magalloway River, located in the Androscoggin River watershed of Maine and New Hampshire.
The river rises in Pittsburg, New Hampshire, south of 2714feet Prospect Mountain, and flows east into Maine. The West Branch of the Little Magalloway joins the Middle Branch 0.7miles upstream of the Middle Branch's juncture with the Little Magalloway, itself only 0.3miles above that river's end at Aziscohos Lake.
