A tortoise shaped island emerges as water levels of the Three Gorges Reservoir fall in Yunyang county, Southwest China's Chongqing municipality, March 12, 2015. The Three Gorges Dam, the world's largest water control and hydropower project on the Yangtze River, has been discharging water to downstream areas in spring. The island, actually a part of a mountain, has little left above water when the water level hits its peak height of 175 meters. [Photo/China News Service]
