The Scituate Reservoir is the largest inland body of water in the state of Rhode Island. It has an aggregate capacity of 39 billion US gallons (150,000,000 m3) and a surface area of 5.3 square miles (14 km2). It and its six tributary reservoirs—which make up a total surface area of 7.2 square miles (19 km2)—supply drinking water to more than 60 percent of the state population, including Providence.
The surrounding drainage basin that provides water to the reservoir system covers an area of about 94 square miles (240 km2), which includes most of the town of Scituate and parts of Foster, Glocester, Johnston, and Cranston. The Scituate Reservoir is operated by Providence Water Supply Board.
