Cambodia: Heightened flood risk in northeast due to collapsed dam

Event

The Ministry of Water Resource and Meteorology warned of a heightened flood risk in the northeast areas of the country along the Mekong river, specifically in Stung Treng province, due to a dam that collapsed in southern Laos on Monday, July 23. Flood warnings have not been issued as of July 24, but officials expect water levels to continue to rise as rain is forecasted in Stung Treng through Sunday, July 29.

Context

A hydropower dam collapsed on Monday, July 23, in Attapeu province in southern Laos, causing a flash flood that has left 6000 people homeless. Several people have reportedly been killed while hundreds remain missing as of July 24.

Cambodia has experienced heavy rains and flooding since the start of monsoon season, which typically begins in May and lasts through November.

Advice

Individuals in the above areas are advised to avoid any areas directly impacted by flooding, monitor the situation, and adhere to any instructions issued by the local authorities (e.g. potential evacuation orders). Remember that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult - and that floodwater may contain wastewater or chemical products; all items having come into contact with the water should be disinfected and all foodstuffs discarded. Be aware that the risk of contracting water- and mosquito-borne diseases tend to rise after periods of heavy rains.
