Stony Brook (Boston)
Stony Brook is a major watercourse, now almost entirely covered, in the city of Boston, USA. It runs through a culvert for 7.5 miles, along almost its entire length; despite being underground, it is the largest tributary stream of the lower Charles River. It originates at Turtle Pond in the Stony Brook Reservation; it flows through Hyde Park, Roslindale, Jamaica Plain, and Roxbury. It empties into the Charles River Basin just upstream of the Massachusetts Avenue bridge; it formerly emptied into the Back Bay when that was a tidal estuary of the Charles River.
In the 18th century, water-powered industry grew up along it (including Pierpoint('s) Mill) and it served as the sewer (excluding human waste) for the neighborhoods it ran through.
The Boston and Providence Railroad (now the Providence/Stoughton Line) was built along the valley of Stony Brook in 1834.
In the 19th century, many breweries and other industries grew up along Stony Brook.
In the late 19th century, various parts of Stony Brook were converted into underground culverts or sewers. In around 1882, the Back Bay Fens were dredged to convert them into a holding basin for storm overflow from Stony Brook, following Olmsted's plan, and at around the same time its waters were diverted into an intercepting sewer near the current Ruggles Station.
