Mandai River, Singapore
Mandai River is a natural watercourse in the northern part of Singapore, flowing through the lush Mandai forested region before emptying into the Upper Seletar Reservoir. It plays an important role in channeling rainwater from the surrounding catchment area into the reservoir system while supporting the area’s rich biodiversity.
Quick Facts

The Mandai River meanders through one of Singapore’s most ecologically rich regions, the Mandai Forest. This forested catchment is home to a variety of native species including birds, reptiles, and small mammals that depend on the river and its banks for water and habitat. The natural landscape surrounding the river contributes to the cooling of the environment and the filtration of rainwater before it reaches the reservoir.
Several conservation efforts are in place around the Mandai region to ensure that development and wildlife protection coexist harmoniously. Projects such as the Mandai Rejuvenation Plan have integrated the preservation of waterways like the Mandai River into the overall master plan for sustainable eco-tourism and biodiversity conservation in the area1.
