North Branch River

The North Branch River is an river in southeastern New Hampshire in the United States. It is a tributary of the Lamprey River, part of the Great Bay and Piscataqua River watershed leading to the Atlantic Ocean.
The river begins in Bear [Brook State Park], in Deerfield, New Hampshire, at the outlet to Beaver Pond. Flowing southeast, it quickly leaves the park, then enters the town of Candia. It passes under New [Hampshire Route 43] just south of the village of Candia, then reaches NH 27 just before entering the town of Raymond, where the river ends at the Lamprey River.
