Stony Brook (Charles River tributary, Weston)


Stony Brook is a stream largely running through Lincoln and Weston, Massachusetts, then forming the Weston/Waltham boundary, and emptying into the Charles River across from the Waltham/Newton boundary. It has two tributaries, Cherry Brook and Hobbs Brook, and its watershed includes about half of Lincoln and Weston as well as parts of Lexington and Waltham. Since 1887, it has been the water supply for Cambridge.
Various water mills have been erected at the mouth of Stony Brook: a corn mill in 1679-80; a paper mill in about 1802.
In the late 19th century, Eben Norton Horsford identified the mouth of Stony Brook as the location of a supposed Norse city, Norumbega, and commissioned the Norumbega Tower, which carries a long inscription describing the supposed city.
There are three large ponds, all artificial, in the Stony Brook watershed: the Cambridge Reservoir, the Stony Brook Reservoir, and Flint's Pond.
In 1887, on the site of Turtle Pond, the city of Cambridge completed construction of the Stony Brook Reservoir Dam, where Stony Brook joins the Charles, as part of its water supply. Stony Brook Reservoir has a drainage area of and an available storage capacity of . In 1910, Hobbs Pond was dammed to become the Cambridge Reservoir.
