Concord River

About

Concord River — 'Shot Heard 'Round the World,' April 19, 1775. The valley's earliest story is written in its old name. The Concord was called Musketaquid, or "grass-ground river," by the indigenous peoples who inhabited the valley for thousands of years. The broad meadows along the water provided rich agricultural land and made the corridor a center of Native settlement before English colonization arrived in 1635. That same low, marshy geography — the reason the river spreads and slows — is what later drew both farmers and, eventually, a national wildlife refuge to its banks.

The Concord's place in history was fixed on the morning of April 19, 1775. Approximately 400 Colonial militiamen and minutemen from Concord and surrounding towns assembled at the Old North Bridge to face 90 British regulars of the 4th Brigade. The militiamen fired the "shot heard 'round the world," the British column retreated toward Boston, and a quiet Massachusetts stream became a fixture of the American founding.

In the decades that followed, the river worked for a living. The 1790–1825 period was the Concord's heyday as a transportation artery, and in 1803 the Middlesex Canal was built to parallel the river from Concord to Charlestown. Then came a different kind of fame. In 1839, Henry David Thoreau and his brother John paddled the Concord and Merrimack rivers; Thoreau's account, published in 1849 as "A Week on the Concord and Merrimack Rivers," became one of the foundational texts of American nature writing.

The watershed also carried the mark of heavier industry. From the 1830s through the 1920s, the Concord River watershed was logged to support the regional timber industry and the era's railroad expansion, worked by local sawmills, logging drives, and downstream lumber operations. The exhaustion of old-growth stands by 1910, the start of state forestry conservation in 1915, and the establishment of state forests in the 1930s together ended large-scale logging in the valley.

The twentieth and twenty-first centuries brought protection and repair. Minute Man National Historical Park was established in 1959 to preserve the ground where the fighting opened, including the Old North Bridge. On April 9, 1999, the river was added to the Sudbury-Assabet-Concord Wild and Scenic River, a federal recognition of its ecological and historical worth. Beginning in 2010, regional agencies and local watershed partnerships have addressed more than a century of logging, agricultural, and industrial impacts through streambank stabilization, native fish restocking, nutrient-reduction work, and water-quality improvements. Today the Concord flows quietly at a mild pace — a Class I river with an average flow near 320 cubic feet per second, gauged at USGS station 01099500 — carrying paddlers past its famous bridge and through the meadows of Great Meadows National Wildlife Refuge.
