This “river” is one of those inlets from the sea that is not a true river. It had been tidal as far inland a Bath until a dam was constructed that created ponds above it.
At its northern most reach the Peterson Canal once linked Merrymeeting Bay with Casco Bay. Built around 1790 to connect Merrymeeting Bay with the New Meadows River, it bypassed the strong currents of the Chops in Merrymeeting and made downstream transportation of logs much easier.
The pond or lake north of U.S. Route 1 in Bath offers year around fishing opportunities. Proposals to remove the dam have been met with resistance from fishermen and shore-side residents.
Further south the New Meadows shares its banks with Brunswick and Harpswell on the west, and West Bath and Phippsburg on the east until it reaches Casco Bay.
