In summer of 2020, the area of the reservoir is 2573,901 m² and its perimeter is 10,197 m. It is classified to be the medium in Reservoir Classification System. The main water is provided by precipitation, seasonal snow melt water and water from the Yinma River. The annual precipitation in the region is about 700 mm, and the annual average temperature is 5.3 ℃. The lowest temperature appears in January, with an average of -18.4 ℃. The reservoir was built in 1958, with a storage capacity of 1.9x10⁷ m³. The average water depth is 3 m, and the maximum depth is 8 m. The bottom of the reservoir is silt with a thickness of 180 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 contents of arsenic, chromium, cadmium, lead and zinc are zero, copper is 0.0004%, nickel is 0.0003%, mercury is 0.00004%, and the pH value is 7.4. The suitable period for Winter Fish-catching is from December 15th to January 20th. The dataset is developed based on Google Earth image.
