The Marina Barrage is a dam in Singapore built across the Marina Channel between the reclaimed lands of Marina East and Marina South. It was officially opened on 1 November 2008 .

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. This structure will provide flood control by changing the tide flow into the barrage.

The building of the Marina Barrage required the relocation of Clifford Pier from Collyer Quay to Marina South.

It is open for viewing 24/7. However, the information counter is only open from 10.00am to 6.00pm. Tours for a maximum capacity of 80 people to the Visitor Centre can be arranged prior to arrival.

Marina Barrage is also a place for teenagers to camwhore and to relax their mind . Transport to here is by taxi or shuttle bus only .
