Contoocook River

About

Contoocook River, New Hampshire — 1725 Penacook-Abenaki, 1782 First Bridge, Henniker Mills. The river's numbers set expectations for the boat. The USGS gauge 01085000 records an average of about 620 cubic feet per second, and paddlers find the Contoocook most agreeable between 200 and 1200 cfs — a Class I–II window that rewards open canoes and beginners as readily as it does anglers working the seams. Across its 80 miles, the grade never demands the hard whitewater skills of steeper New England rivers. It is a river of long, readable stretches rather than continuous drops.

Those miles fall into three natural sections. The upper headwaters from Jaffrey to Peterborough run as Class I water. Below Peterborough, the river stiffens slightly to Class I–II through the covered-bridge corridor down to Henniker. From Henniker to Penacook the Contoocook eases back to Class I on its lower run toward the Merrimack confluence. The middle section carries the river's most recognizable scenery — the covered bridges that give the surrounding Covered Bridge Scenic Byway its name.

Human use here runs deep. The valley was Pennacook territory, and the river served as a travel and fishing corridor through central New Hampshire. The name itself descends from an Abenaki word, variously rendered as "nut trees river," "river of the pines," or "the place of the river near pines." When colonial settlement arrived, it clustered along the water: Henniker was chartered in 1768, named for the Henniker family who received the original grant, and the river's first recorded bridge crossing came in 1782 at Henniker. The stone double-arch bridge associated with Edna Dean Proctor followed in 1835.

The nineteenth century turned the Contoocook into an engine. From the 1830s through the 1920s, its watershed was logged to feed the regional timber industry and the expanding railroads, worked by local sawmills, logging drives, and downstream lumber operations. The industrial peak of the 1880s–1910s was anchored by the Contoocook Mills — grain and paper mills at Hillsborough and Contoocook village — while the Manchester & Keene branch of the Boston & Maine Railroad paralleled the river through the 1890s. Penacook, on the lower reach, sat at the seat of early nineteenth-century New Hampshire industrial power. The end came as the old-growth stands were exhausted around 1910, state forestry conservation began in 1915, and state forests were established in the 1930s.

What survived that era is now protected rather than exploited. In 2004, local conservation groups established the Contoocook River Greenway to safeguard riparian habitat and public access, preserving eight covered bridges and numerous put-ins for paddlers. The river falls under the New Hampshire Rivers Management Program and its Particular Scenic Value designation, and the earliest hydrological understanding of the basin traces to USGS surveys of the 1870s onward, followed by later state streamflow and water-pollution studies. For visitors today, the Contoocook River Canoe Company runs canoe and kayak rentals out of Henniker, putting boats on the same gentle current the Pennacook once followed — the pines and the flow that named the river still intact.
