The reservoir was formed by the Grassy Sprain Brook Dam which impounded the Sprain Brook River and Grassy Sprain River. The reservoir itself has a maximum capacity of 2900 acre.ft, and water from the reservoir is sent to a water filtration plant prior to civil consumption.
The Grassy Sprain Brook Dam is earthen, 40 feet (12.2 m) high, 600 feet (182.9 m) long and drains an area of 1.91 square miles (4.9 km²). In 1919, the City of Yonkers estimated that the reservoir would supply the city for 85 days which is a gross underestimation compared to the population of Yonkers today.
