The barrage acts as Singapore's 15th reservoir, the first to be located in the heart of the city center.
It is equipped with nine crest gates that allow excess water from the catchment area to be released during low tide.
The entire structure is built on a catchment area spanning 10,000 hectares, roughly one-sixth of Singapore's land area.
The Green Roof was engineered with specialized drainage and soil layers to sustain vegetation while preventing water seepage into the facility below.
The facility was designed to prevent flooding in low-lying areas of Chinatown, Boat Quay, and Jalan Besar.
Marina Barrage is a dam built across the Marina Channel in Singapore that serves as a reservoir, a flood control system, and a recreational space. It features the Sustainable Singapore Gallery, which educates visitors on water management, climate change, and environmental sustainability. The rooftop, known as the Green Roof, is covered in turf and is a popular destination for picnics and kite-flying. The facility regulates the water levels of the Marina Reservoir by discharging excess water into the sea during heavy rain. It connects the city to the Marina Bay district, acting as a functional engineering landmark integrated into the urban landscape.
The highest point of the Green Roof provides a panoramic vantage point of the Singapore Flyer and the Marina Bay Sands skyline.
Bring a kite as the rooftop has consistent, strong sea breezes perfect for flying.
Carry sun protection such as hats or umbrellas as there is minimal shade on the open-air rooftop.
Visit the Sustainable Singapore Gallery early in your trip to better understand Singapore's unique water conservation story.
Do not attempt to swim in the reservoir or the surrounding Marina Channel waters.
The Sustainable Singapore Gallery is typically closed on Tuesdays for maintenance.
Kite-flying is permitted only on the rooftop area; keep pathways clear of picnic gear.
