Sudbury River becomes the source of Boston’s water supply.

With the opening of the Sudbury Aqueduct, the Sudbury River and a number of small reservoirs replaces Lake Cochituate as the source of Boston’s water. They provide a combined capacity of 80 million gallons to serve Boston and the other municipalities that are part of the newly established metropolitan water system. The Sudbury Reservoir (No. 5) opens in 1898 and its 7.2 billion gallon capacity is greater than the watershed and the other reservoirs combined.
