The Gezhen Dam is a multi-purpose dam on the Changhua River in Hainan Province, China. It is located 34 km (21 mi) east of Dongfang. The dam serves mainly to provide run-of-the-river hydroelectric power and to supply water for irrigation. The dam's power plant has an installed capacity of 80 MW while it is designed to provide water for the irrigation of 8,667 ha (21,417 acres). Construction began in 2007, the reservoir began to fill in 2009 and the project was complete in December 2009.[2][3][4][5][6]
