From its source () in Maine Township 6, Range 6, WELS, the river runs northeast by Pleasant Lake and through Mud Lake and Rockabema Lake, then south and southeast through Upper Mattawamkeag Lake and Mattawamkeag Lake to its confluence with the East Branch Mattawamkeag River in Haynesville, about west of the Canada–United States border. Mattawamkeag Lake. Mattawamkeag Lake is east (downstream) of Island Falls. There is a good boat launching area on Upper Mattawamkeag Lake on the east side of U.S. Route  2 about north of Island Falls. Upper Mattawamkeag Lake is at the same level as Mattawamkeag Lake, and boats can easily navigate the short thoroughfare from the south end of Upper Mattawamkeag Lake to the north end of Mattawamkeag Lake. For decades there was a dam at the south end of Mattawamkeag Lake controlling overflow to the West Branch Mattawamkeag River. Water level dropped several feet when the dam was abandoned; and the lake shoreline is rocky where wave action eroded shallow soil. The two lakes provide good habitat for chain pickerel, smallmouth bass and white perch. West Branch Mattawamkeag
