According to a 1992 survey, the TGP reservoir impoundment will inundate 632 km 2 of land, including 24500 ha of farmland and citrus land, and affect habitats of 844100 people under submergence. It was planned to relocate a population of 1.13 million people. The relocation and resettlement of TGP reservoir migrants is a world record in scale and in difficulty.
