Fengman Hydropower Station Reconstruction Project is that newly builds a dam located 120m downstream of the origi- nal one, for which the original structures are fully utilized in the design of the construction water diversion, i.e. taking the origi- nal dam as the upstream cofferdam for the construction of the new project and the hydropower unit in the powerhouse of the phase III hydropower station as one of the discharge passages, meanwhile, the reservoir normally operates with the flood control level during flood season with the regulation and storage capacity of the original reservoir, and thus the reservoir is regulated and con- trolled under the consideration of the relevant flood forecasting result. On the basis of the comprehensive consideration of all the factors mentioned above, the water diversion scheme and criteria are comparatively selected, while the diversion structures are designed as well.
