Marina Barrage

Marina Barrage is a dam in southern Singapore built at the confluence of five rivers, across the Marina Channel between Marina East and Marina South.

First conceptualised in 1987 by then prime minister Lee Kuan Yew to help achieve greater self-sufficiency for the country's water needs, the barrage began construction on 22 March 2005, and was officially opened on 31 October 2008 as Singapore's fifteenth reservoir, the Marina Reservoir.

It provides water storage, flood control and recreation. It won a Superior Achievement Award from the American Academy of Environmental Engineers in 2009. It also turned the previously salt water Marina Bay into fresh water for the first time in its history.
