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 30 October 2008 as Singapore's fifteenth reservoir. It provides water storage, flood control and recreation. It won a Superior Achievement Award from the American Academy of Environmental Engineers in 2009.
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.
When it rains heavily during low-tide, the barrage’s crest gates will be lowered to release excess water from the coastal 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.
It has proved to be a tourist attraction. Marina Barrage is open for viewing 24/7. The information counter is open from 9.00am to 9.00pm daily. Tours for a maximum capacity of 80 people to the Visitor Centre can be arranged prior to arrival.
From 2012 onward, it played host to annual public youth community and cosplay event EOY Cosplay Festival.
The Marina Barrage was conferred the Superior Achievement Award - the highest honour of the competition for the best project entry - at the AAEE Annual Awards Luncheon held in Washington, DC, USA on 6 May 2009. The Marina Barrage beat 33 other entries to take home the top prize in this year's competition organised by the American Academy of Environmental Engineers (AAEE), becoming the second project outside of USA to win the award, in the last decade.
