History


Pre-colonial

Long before European settlers named and shaped the Charles, Native Americans living in New England made the river a central part of their lives. At the time of European colonization in the early 1600s, settlements of Massachusett people were present along the river at '' Nonantum'' in current-day Newton and ''Pigsgusset'' in current-day Watertown. Prior to the arrival of
Puritan The Puritans were English Protestants in the 16th and 17th centuries who sought to rid the Church of England of what they considered to be Roman Catholic practices, maintaining that the Church of England had not been fully reformed and should b ...
colonists in the 1620s, Captain John Smith of Jamestown explored and mapped the coast of New England, originally naming the Charles River the Massachusetts River, which he derived from the Massachusett people living in the region, not from their actual name for the river, ''Quinobequin''. When Smith presented his map to Prince Charles, future King Charles I, he suggested that the Prince should feel free to change any of the "barbarous names" for "English" ones. The Prince made many such changes, but only four survive today, one of which is the Charles River which Charles named for himself. The native name for the Charles River was ''Quinobequin'', possibly meaning "meandering" in Massachusett from ''quinnuppe'' or "it turns." Other sources state this name was transferred from the Kennebec River in Maine to Cambridge by Prince Charles at the time he renamed this river in his name. Still another explanation is that ''Quinobequin'' was a descriptive term for any long body of water for Eastern Algonquin peoples, which European explorers and settlers interpreted as a local proper name. Examples include the ''

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. It remains in use for

, 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. For several years, the Charles River Speedway operated along part of the river.

and Cambridge is almost entirely a work of human design. Owen A. Galvin was appointed head of the Charles River Improvement Commission by Governor William E. Russell in 1891. Their work led to the design initiatives of noted landscape architects Charles Eliot and Arthur Shurcliff, both of whom had apprenticed with Frederick Law Olmsted and Guy Lowell. This designed landscape includes over 20 parks and natural areas along of shoreline, from the New Dam at the Charlestown Bridge to the dam near Watertown Square. Eliot first envisioned today's river design in the 1890s, an important model being the layout of the

, an effort led by James Jackson Storrow. The new dam, completed in 1910, stabilized the water level from Boston to Watertown, eliminating the existing mud flats, and a narrow embankment was built between Leverett Circle and Charlesgate. After Storrow's death, his widow Mrs. James Jackson Storrow donated $1 million toward the creation of a more generously landscaped park along the Esplanade; it was dedicated in 1936 as the Storrow Memorial Embankment. This also enabled the construction of many public docks in the Charles River Basin. In the 1950s a highway, Storrow Drive, was built along the edge of the Esplanade to connect Charles Circle with Soldiers Field Road, and the Esplanade was enlarged on the water side of the new highway. The Inner Belt highway was proposed to cross the Charles River at the Boston University Bridge, but its construction was canceled in the 1970s.

s and submerged vehicles were a common sight, along with toxic chemical plumes that colored parts of the river pink and orange. The Standells sang about the sorry state of the Charles in their 1965 song " Dirty Water". Once popular with swimmers, awareness of the river's high pollution levels forced the state to shut down several popular swimming areas, including Cambridge's Magazine Beach and Gerry Landing public beaches. Efforts to clean up the river and restore it to a state where swimming and fishing would be acceptable began as early as the 1960s, and the program to clean up the Charles for good took shape in 1965 with the creation of the Charles River Watershed Association. In 1978, a new Charles River Dam was constructed downstream from the Science Museum site to keep salt water out of the basin. In 1995, the

declared a goal of making the river swimmable by 2005. In 1996, Governor William Weld plunged, fully clothed, into the river to prove his commitment to cleaning up the river. On November 12, 2004, Christopher Swain became the first person to swim the Charles River's entire length, in an effort to raise public awareness of the river's environmental health. In July 2007, the river hosted the Charles River Masters Swim Race, the first sanctioned race in the Charles in over five decades. A combination of public and private initiatives helped drastically lower levels of pollutants by focusing on eliminating combined sewer overflows and stormwater runoff. Since Weld's stunt, the river's condition has improved dramatically, although it was not deemed entirely swimmable by 2005.

s because of its warm temperature. The water quality of the Charles River is often at its worst after a large rainfall because of pollutants carried by runoff, and sewage overflows. For 2011, the EPA reported that the Charles met state bacterial standards for boating and swimming 96% and 89% of the time on dry days, and 74% and 35% of the time on wet days, respectively. Overall boatability and swimability of 82% and 54% in 2011 compared with 39% and 19% in 1995. In June 2018, the Environmental Protection Agency graded the river's 2017 bacterial water quality "A−".

, the researchers then determined that two major tributaries, the Stony Brook and Muddy River, are the predominant sources of ''E. coli'' in the lower Charles River. Starting in 2007, the Charles River Swimming Club has organized an annual race for its members, but obtains a special permit and must monitor water quality and rainfall in the days leading up to the race. The "first public swim" in the Charles since the 1950s was conducted on July 13, 2013, by the Charles River Conservancy,The Charles River Conservancy was founded by Renata von Tscharner. Charles River Watershed Association (CRWA), Esplanade Association, and DCR. Both the annual race and the Conservancy event have been held in deep water with swimmers jumping in off a dock, to avoid the toxic sediments on the bottom of the river that still make beach swimming dangerous. Swimming without a permit is punishable by a fine up to $250.


Wildlife


Fish

The Charles River is home to a wide range of freshwater fish species and some diadromous species. There are over 25 species able to be found in the Charles and some of the most common freshwater fish include the Redfin Pickerel, Largemouth Bass, Golden Shiner, Yellow Perch, a variety of sunfish (such as Bluegills, Redbreast Sunfish, and Pumpkinseeds), and some species of catfish (Yellow Bullhead, Brown Bullhead, White Bullhead). The diadromous fish (fish that spend parts of their lives in fresh and salt water) that can be found in the Charles are mostly anadromous species (fish that migrate from sea to freshwater to spawn). These include the Alewife Herring, American Shad, White Perch, and Striped Bass. The only catadromous species (fish that migrate from freshwater to sea to spawn) in the Charles is the American Eel. With the many initiatives to improve the health of the river in the years since the formation of the CRWA, the health and variety of fish in the river have greatly improved. One example of this is the reintroduction of American Shad into the Charles. American Shad used to be one of the most common species in the river until the 1800s when population numbers decreased because of new dams and poor water quality. With improved water quality and partial dam breaches created in modern times, the CRWA, along with the Massachusetts Division of Marine Fisheries and the U.S. Fish and Wildlife Service, targeted American Shad as a species to revive in the river's ecosystem. (Archived URL retrieved 22 January 2024) In the years from 2006 to 2011, the river was stocked with millions of shad fry. Research showed that these shad were in fact returning to the river to spawn, a testament to the improved health of the river.
