Nandaqiao Reservoir is one of the winter fish-catching places in Panshi, Jilin province of China. It is located on the Chaoyangbao River in the Huifa River Basin. It is administrated by Changxing Village, Baoshan Town, Panshi City, Jilin Province. It lies between 42°49′42″N and 42°50′37″N, 125°58′33″E and 125°59′16″E. In summer of 2020, the area of the reservoir is 699,296 m² and its perimeter is 5919 m. It is classified to be small 1 in the Reservoir Classification System. The main water is from precipitation, snow melt water and the Chaiyangbao River. The annual precipitation in the region is about 610 mm, and the annual average temperature is 0.6 ℃.

The average water depth is 2 m, and the maximum depth is 2.6 m. The bottom of the reservoir is silt with a thickness of 80 cm. The main function of the reservoir is to irrigate and nourish the downstream rice fields and the second is to breed the fish.
