Abstract: Analysis is done on the discharge of flood and variation of water level in the reservoir at the barrier lake in case of 5-year, 10-year, 20-year, 30-year, 50-year, 100-year and 200-year flood according to reservoir inflow flood process under various design standards at the dam site of the barrier lake, the discharge curve of combination of diversion tunnel and spillway tunnel of the former Hongshiyan HPP, and the ca-pacity curve of the barrier lake reservoir, in order to provide decision basis for flood control in barrier regulation, construction of spillway tunnels, power plants and reconstruction of traffic tunnels in the re-servoir area in the flood season in 2016, and to minimize the flood risk during construction. And three flood events occurring during the flood season in 2015 are selected for water balance analysis. The anal-ysis shows that the reservoir outflow and inflow at the barrier lake in 2015 are well balanced, the actual discharge flow and discharge curve are well consistent with the water level and flow at Tianshengqiao HPP, and the flood is discharged without blockage and is controlled safely. The diversion tunnel from the former Hongshiyan HPP and the spillway tunnel (upper part) on the right bank can jointly discharge flood below standard of the 200-year flood. The water level before the dam is lower than the elevation of the bottom of the sluice channel of the barrier.
