Water flows out of the barrier lake through spillway in Yunlong County of the Dali Bai Autonomous Prefecture, southwest China's Yunnan Province, Dec. 18, 2011. After a twenty hours effort, rescuers had successfully dug a spillway to divert the water from the barrier lake on Sunday afternoon. A landslide, which occurred at 7:50 p.m. Saturday, had blocked the Bijiang River and formed a barrier lake.
