Cochecho River

Cocheco River in Rochester

The Cocheco River ( alternate spelling: Cochecho River) is a river in the southeast of the U.S. state of New Hampshire.

The Cocheco River has its origin 0.6 km southeast of the March's Pond, 1.8 km south of Birch Ridge. From there, the Cocheco River flows predominantly in a southeasterly direction through the Strafford County. At the upper reaches is the small reservoir Waldron Mill Pond. At its river are the towns of Farmington, Rochester and Dover. Southeast of Dover's Cocheco River meets finally on the Salmon Falls River. Both rivers unite to form the Piscataqua River. This forms their common estuary. Below the center of Dover, the tides make the Cocheco River noticeable. The Cocheco River has a length of 56 km and drains an area of 474 km ². The most important tributary of the Cocheco River is the Isinglass River.
