The small river has a long whitewater section in western Warner, passing under the Waterloo Covered Bridge next to an old railroad station, then reaches Interstate 89, after which the river flattens and meanders over gravel bars. A small waterfall at Davisville interrupts the flatwater, which resumes to the river's end, just north of the village of Contoocook, New Hampshire, in the town of Hopkinton.
The small river has a lengthy section with strong currents in western Warner, passing under the Waterloo Covered Bridge near an old railroad station, then approaches Interstate 89, after which it becomes calm and meanders over gravel ridges. A small waterfall at Davisville breaks the peaceful waters, which resumes to the river's endpoint, just north of the village of Contoocook, New Hampshire, in the town of Hopkinton.
