Shao Po, located in the current Shou County in East China's Anhui Province, was an important irrigation project in the Huaihe River reaches. The water resource of the project is from the Bi River. The project was said to be built from 598 to 591BC during the Spring and Autumn Period (770-476BC).

Ever since then, it has played a role in irrigating the nearby area. According to the records, 66,000 hectares of field benefited from the project during the period of 400-1,300AD. But the project was greatly damaged time after time by human activities, especially wars. As a result, the importance of the project in irrigation was diminishing. In 1949, it could only irrigate about 80,000 mu (or more than 5,000 hectares) of farmland. Now it functions as a reservoir in the region.
