Eastern Zhejiang is an important area for the economic development of Zhejiang Province. However, water resources in eastern Zhejiang are relatively poor. After the completion of the north line of East Zhejiang Water Diversion Project, the catchment and drainage connecting rivers of all counties and cities have been dredged, the flood control and drainage capacity of all counties and cities has been improved, the river channels along the line have also been comprehensively renovated, the river network water environment of Shangyu City, Yuyao City and Cixi City along the water diversion line has been significantly improved, and the environmental quality of the area around Hangzhou Bay on the South Bank of Qiantang River has been improved. In order to find out the correlation between the water levels of key nodes of the project and provide more targeted guidance for future scheduling, this paper uses the partial least square method to calculate the relationship between the water levels of each node. It is found that there is a significant correlation between the upper water level of Sanxing sluice and the water level under Xinsan sluice and Mashan sluice, and there is a certain correlation with the upper water level of xinsanjiang sluice and Mashan sluice. The correlation between the upstream water level of Xiaoshan hydroproject and the water levels under xinsanjiang sluice, Heshan sluice and Mashan sluice is obvious; There is the most significant linear correlation between the water level of Hengjiang River in xisantang and the water level of Lingshan, Lingshan, Qitang, Sitou and Sitou. The correlation between the water level of Yangxun bridge, Puqian gate and Qitang gate is also significant, and the correlation of other water level stations is poor. In addition, there is a great correlation between the water level of Yangxun bridge and the downstream water level. Attention should be paid to observing the water level of Yangxun bridge during the dispatching process.
