This project is the risk-reinforcement project of Suyeak Lake Reservoir. Su duck lake reservoir is the first batch of national key reservoirs in danger, from 1986 to 1989 according to the design of one in a hundred years of flood, one in a thousand years of flood calibration for the de-risking and reinforcement, after reinforcement of the total capacity of 1.656 billion cubic meters. Dam by the waterfront slope thickening height of 1 meter, the top of the dam elevation of 59.20 meters. Current engineering standards for the 100-year flood design, 1000-year flood check. Design flood level of 57.75 meters, the corresponding reservoir capacity of 1.272 billion cubic meters, calibration flood level of 58.87 meters, the corresponding reservoir capacity of 1.656 billion cubic meters.
