Upper Peirce Reservoir Park is a 5 hectare park next to the reservoir. The reserve included MacRitchie, Lower Peirce, and Upper Seletar Reservoirs. The nature reserve supplies nearby reservoirs.
Increasing water demand in the 1960s required a higher dam upstream of the existing Peirce Reservoir dam. It was finished in 1975 and opened by PM Lee Kuan Yew on February 27, 1977.
