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.

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
