Charles River - History

History

The river's name, preceding the English version, was once thought to be Quinobequin (meandering), though that attribution has been discredited by, among others, the Harvard University Librarian in 1850. The river was used by Native Americans for local transportation and fishing and as part of the passage from southeastern Massachusetts to northern New England.

Captain John Smith explored and mapped the coast of New England, naming many features, originally naming the Charles River the Massachusetts River, which was derived from the tribe living in the region. When Smith presented his map to Charles I he suggested that the king should feel free to change any of the "barbarous names" for "English" ones. The king made many such changes, but only four survive today, one of which is the Charles River which Charles named for himself.

In portions of its length, the Charles drops slowly in elevation and has relatively little current. Despite this, early settlers in Dedham, Massachusetts, found a way to use the Charles to power mills. In 1639, the town dug a canal from the Charles to a nearby brook that drained to the Neponset River. By this action, a portion of the Charles's flow was diverted, providing enough current for several mills. The new canal and the brook together are now called Mother Brook. The canal is regarded as the first industrial canal in North America. Today it remains in use for flood control.

Waltham was the site of the first fully integrated textile factory in America, built by Francis Cabot Lowell in 1814, and by the 19th century the Charles River was one of the most industrialized areas in the United States. Its hydropower soon fueled many mills and factories. By the century's end, 20 dams had been built across the river, mostly to generate power for industry. An 1875 government report listed 43 mills along the 9.5-mile (15 km) tidal estuary from Watertown Dam to Boston Harbor.

From 1816 to 1968, the U.S. Army operated a gun and ammunition storage and later production facility known as the Watertown Arsenal. While it was key to many of the nation's war efforts over its several decades in operation, not the least of which being the American Civil War and World War I, its location in Watertown so near the Charles did great environmental harm. The arsenal was declared a Super Fund site, and after its closure by the government it had to be cleaned at significant expense before it could be safely used again for other purposes. Likewise, the many factories and mills along the banks of the Charles supported a buoyant economy in their time but left a legacy of massive pollution.
