At the beginning of the 20th century, about 700 kilometers north of the Yellow River in the Grand Canal was cut off, causing serious shortages of water resources in the canal, water ecological damage, and water environment pollution.

　　On April 13, 2022, the Ministry of Water Resources of China, in conjunction with Beijing, Tianjin, Hebei, and Shandong provinces, launched the water replenishment action of the Beijing-Hangzhou Grand Canal in 2022, coordinating the water supply, local water, yellow water, Reclaimed water, rain and floods and other water sources are used to replenish water to the north of the Yellow River, enabling the entire Beijing-Hangzhou Grand Canal to flow water, replacing about 600,000 mu of arable land along the route for groundwater irrigation.

　　Shandong has participated in the water replenishment action of the Grand Canal through two routes: the first phase of the East Route of the South-to-North Water Diversion Project, the North Extension Emergency Water Supply Project and the Panzhuang Yellow River Diversion Project.

The people's governments at all levels along the Grand Canal in the province have invested more than 10 billion yuan (RMB, the same below) to complete 324 pollution control projects, invested more than 9 billion yuan to implement comprehensive renovation and ecological restoration in Dongping Lake District, completed the relocation of 63 villages, resettlement There are 63,000 people in the lake area, ensuring that the water quality of the main water transmission line reaches the surface class III water standard, and provides a reliable guarantee for the transmission of clear water from a canal to the north.

Meter.

After the completion of the entire Grand Canal to the end of May, the length of the rivers with water will increase by about 112 kilometers, and the water surface area is expected to increase by 9.5 square kilometers. The main sections of the canal are expected to be basically filled with water.
