Situation in major dam has improved. Water level in many dams has increased but still not adequate. Currently, amount of water stored is at 31,152 million cubic meters or 44% of total all dam capacity. Amount of usable water is at 7,718 million cubic meters. Major dams could store water more than 39,000 cubic meters. Even though, there are some the water inflows into the dam but the amount is not enough due to low rainfall in the upper area of the dams. The RID announced that all major dams should collect water as much as possible during the rainy season without affect the downstream. Current water flow from major dams at 18 million cubic meters is for consumption and environment only.
