Has the newly-built Miyun Reservoir experienced three migration paths?

It is reported that the three migrations of Miyun Reservoir lasted nearly half a century. The first migration began at the beginning of the construction of 1958 Miyun Reservoir. In order to ensure the construction and flood control of Miyun Reservoir, 65 villages in the reservoir area were relocated and cleared in two batches.

The second migration took place in 1974. The water level of Miyun Reservoir has reached153m, the highest since the reservoir was built. Most of the "treasure land" in the reservoir area (below 157.5 meters) was flooded, and some villages near the reservoir were flooded, making production and life difficult. Therefore, Miyun County decided to relocate some villages to the south of the reservoir again.

The third migration started at 1995. After these immigrants, 90% villages in Miyun County have immigrant households. The reservoir has a total area of 336,000 mu, occupying 240,000 mu of cultivated land, accounting for more than 30% of the total cultivated land in the county at that time. By the early 1990s, the population around the reservoir had been seriously overloaded.

The first batch of immigrants moved out in 1995, which lasted for 6 years. Around Miyun Reservoir, there are12,484 people who immigrated to Tongzhou and Shunyi, and another 2,724 people choose to stay with relatives and friends. Their housing conditions are better than in the past, and they have more arable land and employment opportunities, especially their children's educational conditions have improved, creating good conditions for them to get rid of poverty and become rich.

I hope the water quality and quantity of Miyun Reservoir can be continuously improved!
