The Marina Barrage was constructed across the mouth of the Marina Channel in Singapore between 2005 and 2008. It creates Singapore's 15th reservoir and the first located in the heart of the city. The barrage prevents seawater intrusion, increasing Singapore's water catchment area while also providing flood protection and creating a new recreational space. It was envisioned by former Prime Minister Lee Kuan Yew in the 1980s but took over 20 years to realize due to technical limitations.

3. History By 1987, the government had successfully completed its ten-year drive to clean up Singapore River and Kallang River. It was at this time that then prime minister Lee Kuan Yew, now minister mentor, mooted the idea of damming up Marina Basin to create a large freshwater lake. However, this was not yet feasible with the existing technology. It was only in 2004 that the government set the wheels in motion by calling a tender for the project. The contract was awarded to local contractor Koh Brothers and construction began in early 2005.

4. Built across the mouth of the Marina Channel, the Marina Barrage creates Singapore's 15th reservoir, and the first in the heart of the city. With a catchment area of 10,000 hectares, or one-sixth the size of Singapore, the Marina catchment is the island's largest and most urbanised catchment. Together with two other new reservoirs, the Marina Reservoir will boost Singapore's water catchment from half to two-thirds of the country's land area by 2011. The Marina Barrage is the result of Minister Mentor Lee Kuan Yew's vision nearly two decades ago when he envisaged damming the mouth of the Marina Channel to create a freshwater reservoir.
