Coaticook River
The Coaticook River is a north-flowing river rising in Vermont, United States, and located primarily in the Estrie region of Quebec, Canada. The mouth of the river is located north of Waterville and south of Lennoxville, near the southern border of the city of Sherbrooke, at the Massawippi River. Via the Massawippi and the Saint-François River, it is part of the St. Lawrence River watershed. Name. The name for the Coaticook River comes from the Abenaki name "koatikeku" which means "River of the land of the white pine". White pines were common in the surrounding region  and the nearby upper Connecticut River valley. Names such as "Coös", as in Coös County, New Hampshire, are derivative from this type of tree. The toponym "Coaticook River" was officialized on December 5, 1968, at the Commission de toponymie du Québec. Geography. The source of the Coaticook River is Norton Pond (length , altitude ), in Essex County, Vermont, south of the Canada–US border. The valley holding this lake continues south across a low height of land, draining via the Pherrins River into the Clyde River at Island Pond, Vermont. The Coaticook River flows northward on American territory, crossing a forested  and agricultural valley. A railway and Vermont Route 114 follow the river on the east side. After crossing the international border, the river enters the municipality of Coaticook and flows generally north through: North of Waterville the Coaticook joins the Massawippi River from the south, upstream from the confluence of the Rivière aux Saumons and upstream from the mouth of the Massawippi at the Saint-François River at Lennoxville, southeast of the center of Sherbrooke.
