The West Branch Oswegatchie River is a river in Herkimer, Lewis, and St. Lawrence counties in New York. It starts at the outlet of Hog Pond and flows into the Oswegatchie River near the hamlet of Talcville. The West Branch Oswegatchie River is slower-moving than the Middle Branch, which flows into it. But the still waters such as Long Pond, Round Pond, Rock Pond, Mud Pond and Long Level are separated by hard-to-traverse rapids and/or waterfalls.
