Mekong mainstream dams
Healthy rivers require connections to all parts of a free-flowing ecosystem to be economically, environmentally and socially beneficial to a shared future. 12 hydropower dams are proposed for the lower Mekong mainstream. If built these dams will cut across the whole river creating a barrier that will seriously impact the flow and hydrology of the Mekong. Xayaburi Dam in Laos is the first Mekong mainstream dam to begin formal procedures for construction. Sambor Dam in Cambodia if built will force the relocation of more than 19,000 people.
