Analysis of impact and treatment measures of raising the impoundment level of Jiaogang Lake
To implement the revision of the scheduling and operation method for adjusting and controlling lake characteristic water levels,and to fully utilize the water storage function of the regulatory lakes,a study was conducted to explore the impacts of raising the storage water level of Jiaogang Lake to 18.30,18.50,and 19.00 meters during the non-flood season.The study examined the effects on regional floodplain inundation,flood control and drainage,water conservancy projects,and other water-related projects.It proposed countermeasures such as compensating drainage fees,updating and renovating sluices,dredging drainage channels,and reinforcing lake embankments.Additionally,the study analyzed the benefits for water supply,drought resistance,and ecological benefits.It is recommended that the storage water level during the non-flood season be controlled at 18.50 meters,with further elevation plans to be studied in conjunction with the Huai River management project and socio-eco-nomic development in the long term.The research results could provide decision-making reference for adjusting the character-istic water level of lakes.
