Abstract: Restricted by factors such as concentrated inflow within the year, the full storage rate of Za ⁃ oshi reservoir at the end of flood season is relatively low. To improve the water resource utilization effi ⁃ ciency of Zaoshi reservoir, on the basis of fully analyzing the necessity and feasibility of advanced water storage at the end of flood season, this study has comprehensively compared the benefits of multiple ad ⁃ vanced water storage schemes and analyzed the risks of advanced water storage. The results show that the time for advanced water storage of Zaoshi reservoir should not be earlier than middle and late July, and it should be implemented on the basis of considering weather conditions and preventing possible heavy rainfall. The earlier Zaoshi reservoir starts water storage and the higher controlled storage level at the end of July, the higher the full storage rate after flood season. Considering the current flood control situation of Lishui river basin and the role of reservoir flood control, it is suggested that the pre-storage level of Zaoshi reservoir should not exceed 130 m on July 20th and not exceed 132 m at the end of July. If a flood occurs during the advanced water storage process, the water storage should be suspended and the regulation should be promptly switched to meet flood control requirements.
