It is located on the western slope of Changbai Mountain and adjacent to the Huifa River, a tributary of the Songhua River. It is administrated by Hulanhe Village, Heishi Town, Panshi City, Jilin Province. It lies between 42°52′45″N and 42°52′55″N, 126°33′10″E and 126°33′28″E. In summer of 2020, the area of the reservoir is 50,806 m² and its perimeter is 1295 m. The reservoir is a pond. The main water is from precipitation, seasonal snow melt water and river supply. The annual precipitation in the region is about 400 mm, and the annual average temperature is 12.4 ℃. The lowest temperature appears in January, with an average of -8 ℃. The reservoir was built in 1956, and had a storage capacity of 1.1x10⁴ m³. The average water depth is 3 m, and the maximum depth is 5 m. The bottom of the reservoir is silt with a thickness of 60 cm. The main function of the reservoir is to irrigate and nourish the downstream rice fields and the second is to breed the fish.

The suitable period for Winter Fish-catching is from 1st to 20th in January. The dataset is developed based on Google Earth image. It is archived in .shp and .kmz data formats, and consists of 17 data files with data size of 40.3 KB (Compressed into two files with 13.2 KB).
