The Kallang River (Chinese: 加冷河, Pinyin: Jiālěng Hé) flows for 10 kilometres from the Lower Peirce Reservoir to the coast at Nicoll Highway, making it the longest river in Singapore. The river mouth was traditionally at Kallang Basin, although extensive land reclamation around the area meant the river only flows into the open sea via the Marina Channel between Marina Centre and Marina East.
