Early November 2017, storm no. 12 (Typhoon Damrey) with level 12 winds, level 15 gusts and heavy rain made a landfall on the central coast of Vietnam. Fearing that the increasing water levels would risk reservoir safety, many hydropower reservoirs opened their floodgates and released huge amounts of water for several days continuously, causing extensive flooding downstream.
