Lake Diànshān

Lake Dianshan lies east of Lake Tai in the low-lying Jiangnan water network. Its waters drain toward the Wusong River through channels such as the Daying and Zhaotun. As the Wusong silted up and drainage routes became obstructed, water accumulated in the region and the lake expanded. In 1293, after wealthy landholders enclosed lakeside fields and worsened flooding, the official Pan Yingwu had new channels opened and older outlets dredged to restore the flow.
