The North River is a river in the municipality of Havelock-Belmont-Methuen, Peterborough County in Central Ontario, Canada.[1] It is part of the Great Lakes Basin, and is a right tributary of the Crowe River.
The river begins at Imp Lake in geographic Methuen Township[2] and flows south, past the Blue Mountain Mine at Devil's Lake, to Kasshabog Lake. It continues south to Long Lake, then turns east, then resumes a southward direction, and enters geographic Belmont Township.[3] The river passes through Round Lake, turns east, and reaches its mouth at Belmont Lake on the Crowe River, which flows via the Trent River to Lake Ontario.
