Today's Charles River basin between Boston 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.
