Here is part of the writeup posted at the Hopkinton Dam kiosk:
The Hopkinton State Park Reservoir Dam was completed in 1895 to impound the flow of Indian Brook thus creating a reservoir to supply water to the city of Boston. The dam and reservoir are now primarily used for recreation, flood control, and to supply fresh water to the swimming pond located at the downstream toe. The reservoir it creates also serves to recharge ground water to the Town of Ashland's Water Supply Wells, located to the south of the reservoir. Designed by Frederick P. Sterns, Chief Engineer of the project, the dam stands 58 feet high, stretches 1,616 feet, and impeeds a water surface of 193 acres. Approximately 6,850 acre feet of water, or 2.2 billion gallons, is contained in the reservoir at its optimum level. It is interesting to note that 1 inch of rain equals about 102 million gallons of input into the reservoir. The Hopkinton State Park Dam and Reservoir is listed on the National Register of Historic Places for its age, unique architecture, and engineering design. |
