红山水库是一座大型水库，设计总库容２５．６亿ｍ３，至今已运行了３８ａ，水库已产生了严重的淤积，现有库容１６．８亿ｍ３，其特征值已发生了很大变化，综合效益得不到充分的发挥。就水库汛期分期和汛限水位确定进行了探讨，提出了新的汛期分期和汛限水位，据此，对洪水进行科学的调度，能充分发挥水库的防洪和兴利作用。
Hongshan Reservoir is a large reservoir with a designed total capacity of 2.56 billion m3 and has been in operation for 38 years. The reservoir has caused serious siltation with a current storage capacity of 1.68 billion m3 and its eigenvalues have undergone great changes. Comprehensive benefits can not be fully realized. This paper discusses the staging of flood season and the determination of flood control water level, and proposes a new flood season staging and flood control water level. According to this, the scientific dispatching of flood can give full play to flood control and enrichment of reservoirs.
