Photo taken on April 30, 2011 shows water level of the Danjiangkou Reservoir is apparently lower than normal in central China's Hubei Province, May 5, 2011. The Danjiangkou Reservoir, a water supply to China's South-to-North Water Diversion Project which transfers water from south China region to the north, has presented abnormally low water level due to the drought. By 8 a.m. of May 5, the water level here stands at 135.11 meters, even four meters lower than the 139-meter dead water level. [Xinhua]
