•There is an increased risk of landslides in the immediate area around the reservoir and many species, such as white flag dolphin, will have their habitats disrupted
•Between 1998 and 2004 the amount of sediment transported by the river below the dam fell by over 50%, resulting in increased rates of erosion downstream – sediment will accumulate behind the dam and this will require dredging Economic •The creation of the reservoir has forced the resettlement of 1.2 million people from several cities, 11 district centres and over 100 villages to newly built settlements. •Afforestation is needed on the slopes in the drainage basin to reduce the amount of sediment washed into the river and the reservoir behind the dam.
