What is the mine in Shulehe Lake area of Hala Lake?

There are no mines in Shule River and Hala Lake Lake area.

From the Yongzheng period of Qing Dynasty, due to the migration and development of Hexi Corridor, Shule River at the western end of the Corridor gradually stopped flowing and retreated, and the water discharge under Danghe River decreased sharply, and the water surface of Hala Lake began to shrink. In the 1960s, after the completion of the Shule River Shuangta Reservoir, Hala Lake completely dried up.

According to the plan, the ecological water discharged by Shuangta Reservoir and Danghe Reservoir in Shule River has increased year by year in recent years, and 10%-20% of the incoming water is discharged into the river for ecological water supply in the lower reaches of the river. With the completion of the bundled regulation project of Shule River and Danghe River in the planning, the ancient river channel has been regulated, and the water delivery efficiency of the river channel has been improved. The discharged ecological water and flood in flood season meet on the regulated river channel. In 20 16, the ecological displacement of the two rivers is about 50 million cubic meters. After freezing in winter and melting in spring, blue waves reappeared in Hala Lake, which had been dry for more than half a century, in early spring and March.
