Lake

The Batang Ai lake was created in 1985 with the damming of the Ai river. It currently has an area of 90 km². The power station of the dam has four 25 MW turbines, with a total power generation capacity of 100 MW. The lake deeply extends with its arms into the region, getting close to the Indonesian border. With the flooding of the Ai river area in 1985, the local Iban communities (3000 people of 26 communities) were relocated to higher ground.
