Geylang River (Malay: Sungai Geylang; Simplified Chinese: 芽茏河) is a canalised river flowing from Geylang to Kallang of the Central Region in Singapore. With the formation of the Marina Reservoir after the completion of the Marina Barrage in 2008, the river now forms part of the reservoir.
Geylang River begins at Ubi as Geylang Canal, continues southwards, and turns westwards after Geylang Road, but flows southwards again near Guillemard Road, before turning westwards again after Dunman Road. The river finally empties into the Kallang Basin near Tanjong Rhu in the southern part of Kallang.
Geylang River has gone through a two years long revamp initiated by the Public Utilities Board (PUB) programme, which revitalised the waterway while preserving the rich heritage of the areas around Geylang River, and was opened by Guest-of-Honour Associate Professor Fatimah Lateef, Member of Parliament for Marine Parade Group Representation Constituency. As part of the revamp, Geylang River was also deepened and widened to increase its capacity and enhance flood protection. A natural rain garden which treats surface runoff using plants and soil was also set up to improve the quality of the river’s water.
