The IBA comprises a freshwater reservoir with about 120,000 ha of open shallow water that does not exceed 1-2 m in depth. There are reedbeds in the centre of the reservoir which provide good habitat for waterbirds. It is located in the least developed part of Shenyang and the habitats are still in good condition. However, over-fishing, bird egg collection and hunting are threats to the waterbirds in the area.
