Cochecho River at Rochester, New Hampshire, c. 1905

The Cochecho River or Cocheco River is a tributary of the Piscataqua River, 38.3 miles (61.6 km) long,[1] in the U.S. state of New Hampshire. It rises in northern Strafford County and runs southeastward, through the town of Farmington and the cities of Rochester and Dover, where it provides hydroelectric power. Below the center of Dover, the river is tidal and joins the Salmon Falls River at the Maine border to form the Piscataqua.

Significant tributaries include the Ela River, the Mad River, and the Isinglass River.

Significance of name[edit]

Cochecho is an Abenaki word believed to mean "rapid foaming water," referring to the river's falls in downtown Dover. Settlers in 1623 adopted the name for the entire river and their settlement, Cochecho Plantation. It is believed the shift from Cochecho to Cocheco can be traced to a clerical error at the 1827 incorporation of the defunct Cocheco Manufacturing Company.[2] Cocheco was adopted as the official spelling in a 1911 decision by the United States Board on Geographic Names. The river has also been known as the Dover River.[3]

On July 3, 2015, the United States Board on Geographic Names received Name Change Proposal 8753, a petition to officially realign spelling of the Cochecho River with historic Cochecho Plantation -- see Talk:Cochecho River.
