A dam was built in Jinzhai in the 1950s to lessen the flow of the Huai and prevent flooding. The resulting Xianghongdian Reservoir provides drinking water. Along with Foziling and Meishan, the Xianghongdian is one of the largest reservoirs on the Huai. The dams, built during the Great Leap Forward promoted by Mao Zedong, are dilapidated and in urgent need of reinforcement. Jinzhai, Anhui Province, February 2011
