Marina Barrage


Marina Barrage is a dam built across the mouth of the Marina Channel, creating the Marina Reservoir. The reservoir is 10,000 ha and is Singapore’s first reservoir in the heart of the city. The reservoir is fed mainly by the Singapore, Kallang, Geylang and Rochor rivers. The Marina Reservoir was created to help alleviate flooding in low-lying areas of the city and at same time contribute to Singapore’s water supply.

As the water in the Marina Reservoir is unaffected by the tides and its water level is kept constant all year round, it is ideal for all kinds of water-based recreational activities such as boating, windsurfing, kayaking and dragonboating.

Prior to the erection of the Marina Barrage separating the Marina Basin (reservoir) from the open sea, a survey on the fishes within the basin was done. Results from the survey can be found here. A list of the fishes that might have survived the desalination of water in the Marina Reservoir is also documented.
