The southern section of Jining, Shandong Province is navigable and the northern section is silted. This section from Guo Na to Liangshan is called Dongping Lake West Waterway, which is 20 kilometers long. Although dredging was carried out at 1968, the river channel was seriously silted and the water depth was insufficient, so it was not navigable. The total length from Liangshan to Wang Nan is 33.8 kilometers, and the water depth of the waterway is 0.5 meters in dry season, and it can be navigable for 6 months every year. This is a seasonal waterway. The Wang Nan-Jining section is 27. 1 km long, with a bottom width of15m and a water depth of 0.5m in dry season. It can only be navigable for six months every year, and it is a seasonal waterway. Jining to the second dam section is 78. 1km, and the channel is straight. In dry season, the water depth is more than 1m, and the bottom width is 50m, which can be used for ships of100t class.
