PUB Ecological study in Marina Reservoir

PUB, the national water agency and the National University of Singapore will be carrying out an ecological study at the Marina Reservoir from April to May 2016.  We seek your kind cooperation to temporarily stop all recreational water activities at the reservoir on the following days/times for safety reasons.

Generally, Kallang Basin will be closed on Mondays and Fridays every alternate week and Marina Bay and Channel will be closed on Wednesdays and Fridays on the same week. As Friday is a back-up date in the event of poor weather, we will inform you by Thursday morning if the date is not required.
