'''Upper Peirce Reservoir''' ([[Simplified Chinese|Chinese]]: 贝雅士蓄水池上段) is [[Singapore]]'s fourth [[water reservoir|reservoir]]. The 6-[[hectare]] [[Upper Peirce Reservoir Park]] overlooks the Upper Peirce Reservoir.

==History==
Originally known as the Kallang River Reservoir, Singapore's second reservoir was impounded across the lower reaches of the [[Kalang River]] in 1910. In 1922, it was renamed Peirce Reservoir in commendation of the services of Robert Peirce, who was the [[municipal]] [[engineer]] of Singapore from 1901 to 1916.

In late 1960s, due to increasing demand for water and the need to increase the capacity of Peirce Reservoir, a higher dam was constructed upstream of the existing dam at Peirce Reservoir in 1970.

In 1975, a major water supply project to develop new water resources was undertaken to support Singapore's rapid housing and [[industrialisation]] programmes. A dam was constructed at the upper reaches of the Peirce Reservoir, forming the Upper and [[Lower Peirce Reservoir|Lower Peirce]] Reservoirs.

Upper Peirce Reservoir was officially opened by then [[Prime Minister of Singapore|Prime Minister]] [[Lee Kuan Yew]] on 27 February 1977. The fourth and largest reservoir of Singapore has a capacity of 27.8 million m<sup>3</sup> of water over 304 hectares of water surface.

==Upper Peirce Reservoir Park==
{{main article|Upper Peirce Reservoir Park}}
Upper Peirce Reservoir Park is a 5 hectares park beside the reservoir. Adding to its local scenery is the surrounding [[secondary forest]] which was protected as a [[water catchment area]] when the reservoir was built.{{fact|date=July 2024}}
