As monsoonal rains drench Laos and rivers continue to rise across the country, several hydropower projects have been forced to release water. Where are these dams, and when have they released water?

The government received alerts from five hydroelectric plants in recent days regarding the release of water from their dams, according to the Ministry of Energy and Mines.
