 Another major challenge was the resettlement of around 330,000 persons who were living near Danjiangkou Reservoir (at its prior, lower elevation), and along the route of the canal.On October 18, 2009, Chinese officials began to relocate residents from the areas of the Hubei and Henan provinces who were to be affected by the reservoir.The completed canal route is approximately 1,264 km long, initially providing 9.5 km3 of water annually.
