The Marina Barrage (Chinese:滨海堤坝) 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$226 million 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 from half to two-thirds 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.
The building of the Marina Barrage required the relocation of Clifford Pier from Collyer Quay to Marina South (see Marina South Pier). 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. In 2012 and 2013, 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.
