There are two large national reservoirs in the area, Shahe and Daxi. It is the first batch of eco-tourism demonstration zones in Jiangsu Province.

In 1957, Jiangsu water experts visited Liyang to study the local topography. It is found that there are continuous green mountains on both sides of the Shahe River in Yima Pingchuan. For example, in the lower reaches of the Shahe River, it should be a good thing that can block the water, use water to generate electricity, irrigate the fields, protect the drought and flood, and benefit the people. Therefore, the Shahe Reservoir has been built.

In 1992, in order to meet the needs of reform and opening up, Shahe Reservoir was transformed into Tianmu Lake.
