 One long-term solution being considered is to build another canal to divert water from the Three Gorges Dam to Danjiangkou Reservoir.On Friday, Dec. 12, 2014, the middle leg of China’s South to North Water Project, the world’s largest water transfer project to date, opened.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.
