This paper briefly describes the basic situation of the Sanjiaozhou Reservoir in Panjin City

Liaoning Province and determines the analysis path of its rainstorm resistance capacity in combination with the province's work arrangement on reservoir rainstorm resistance capability analysis. Hydrological calculations are carried out to calculate the inflow flood of the Sanjiaozhou Reservoir. In light of its flood regulation mode and discharge situation

this paper analyzes the reservoir's rainstorm resistance capability under different initial dispatch stages

and introduces the results of reservoir resilience to heavy rainfalls

alongside relevant flood control measures.
