Does Jinzhou Daoling River Reservoir release floods every year?

Yes. According to the Jinzhou official website, Jinzhou Daolinghe Reservoir conducts flood discharge operations every year due to rainfall and other reasons to prevent flood disasters in the area. Usually during the annual flood season (summer) and continuous rainfall, the water level in the reservoir will rise to a certain height. If it exceeds the carrying capacity of the reservoir, flood discharge operations will be required. Flood discharge can be achieved by opening the reservoir's sluice, allowing excess water to flow out of the reservoir to maintain the safe and stable operation of the reservoir.
