The Marina Barrage is a dam in Singapore built at the confluence of five rivers, across the Marina Channel between Marina East and Marina South. It was officially opened on 1 November 2008. It was Singapore's fifteenth reservoir. It provides water storage, flood control and recreation. It won a 2009 AAEE award.
The S$3 billion project turns Marina Bay and Kallang Basin into a new downtown freshwater Marina Reservoir. It provides water supply, flood control and a new lifestyle attraction.
By keeping out seawater, the barrage forms Singapore’s 15th reservoir and first reservoir in the city. Marina Reservoir, together with the future Punggol and Serangoon reservoirs, will increase Singapore’s water catchment areas to one-sixth of Singapore’s total land area.
Marina Barrage also acts as a tidal barrier to keep seawater out, helping to alleviate flooding in low-lying areas of the city such as Chinatown, Jalan Besar and Geylang.
When it rains heavily during low-tide, the barrage’s crest gates will be lowered to release excess water from the reservoir into the sea. If heavy rain falls during high-tide, the crest gates remain closed and giant drainage pumps are activated to pump excess water out to sea.
As the water in the Marina Basin is unaffected by the tides, the water level will be kept constant, making it ideal for all kinds of recreational activities such as boating, windsurfing, kayaking and dragonboating etc.
The building of the Marina Barrage required the relocation of Clifford Pier from Collyer Quay to Marina South (see Marina South Pier).
