Entering the Yunding Ski Park and going up the winding road, you will see a large open-air cistern.
According to reports, the stadium has built a snow-making water diversion system, with 3 open-air storage tanks and 1 underground snow melt water collection tank, with a total water storage capacity of 280,000 cubic meters.
These reservoirs can collect snowmelt water, natural precipitation and surface runoff water in spring and summer, and cooperate with water diversion pipelines and pumping stations to send the water source to the race track along the mountain to provide water source protection for winter snowmaking.

According to reports, when there is no need to make snow in summer, the reservoir can be discharged into the river after it is filled with water. The surrounding villagers can use the water in the river to irrigate farmland to realize the effective collection and recycling of natural precipitation in the competition area.
In addition, the artificial snowmaking system of Yunding Ski Park adopts the world's advanced and efficient water-saving artificial snowmaking equipment and intelligent snowmaking system, which can maintain the best snowmaking efficiency according to the dynamics of the external environment.
