Since Dahua Hydropower Station was put into operation a large number of crop wastes roots and bamboo havebeen accumulated in front of the reservoir inlet during annual flood season because of more floaters in the reservoir area. Thesewage can not be removed in time due to the insufficient sewage disposal facilities which blocks guide blade of unit in thehydropower station.
