To enhance the production efficiency of the Poyang Hydrology and Water Resources Monitoring Brigade，in accordance with the requirements of the “Hydrology Survey Specifications”，this study selects hydrological data from the Lianhua Hydrological Station spanning nearly five years from 2020 to 2024 for intermittent measurement analysis.Through analysis of the testing facilities and equipment，cross-section stability，alignment error，and annual，seasonal，and flood volume at the Lianhua Hydrological Station，it is found that a comprehensive line can be established above a water level of 23.00 m，and all errors meet the specification requirements. It is possible to suspend measurements for 2-5 years and conduct measurements once a year. For water levels below 23.00 m，measurements should be conducted 3-5 times a year，and a temporary curve for low and dry water periods should be established. During data compilation，a comprehensive line is used for flow calculation above 23.00 m，and a temporary curve method is used for flow calculation below 23.00 m.
