Yishun Dam (formerly known as Sungei Seletar Dam) is a dam in northern Singapore, built in 1984 as part of the Sungei Seletar and Bedok water scheme and forms the Lower Seletar Reservoir.
History
[edit]In 1980, a study was conducted for a scheme to build two reservoirs in Sungei Seletar (now known as Lower Seletar Reservoir) and Bedok.[1]
In 1983, a S$60.8 million contract was awarded to Loh & Loh Construction Pte. Ltd. from the Public Utilities Board (Singapore) for the construction of the dam.[2]
The dam was completed on 28 April 1984,[3] with dump trucks and bulldozers pushing sand to fill the last gap of the dam. The dual carriageway opened later in the year to motor traffic.[4]
In May 2024, the Land Transport Authority announced plans to expand the road junctions at both sides of the dam,[5] in response to concerns by nearby residents about the heavy traffic in the area during morning and evening peak hours. A new park connector will also be built along the dam, providing a dedicated cycling path for cyclists.
Design
[edit]The dam stretches 975m across the mouth of Sungei Seletar, and incorporates a spillway system and slurry wall that controls the water flow and prevents seawater from the Straits of Johor from flowing into the reservoir.[2] On top of the dam, a dual-carriageway links Yishun New Town to Seletar, providing access to Seletar Airport, Yio Chu Kang Road and Jalan Kayu[4]
