Photo taken on May 30, 2010 shows the facade of the dam of the Three Gorges Water Conservancy Project, in Yichang, central China's Hubei Province. The Three Gorges Reservoir had lowered its water level to 150.40 meters by 8:00 a.m. Sunday from the climax of 171.43 meters during last year's probationary water storage. The water level is to be further lowered to 145 meters by June 10 in a preemptive measure for flood prevention.
