Abstract: The Xiluodu and Xiangjiaba reservoirs of China impounded up to normal water level for the first time in 2013 and 2014, respectively. It marked that the Xiluodu-Xiangjiaba-TGR, an ultra-large type cascade reservoir with 27. 7 billion m3 flood control storage formed on the stem stream of Yangtze River. The research indicated that the flood control standard of emphasis cities on the upstream like Yibin, Luzhou, Chongqing, etc. , and the middle-downstream wide areas such as Jing River, Chenglingji could be improved substantially through the joint operation of cascade reservoirs with large storage and well regulation abilities. The flood control pressure of main stem and branch will be alleviated effectively. In 2014 and 2016, two large floods happened in the Yangtze River basin. But, the flood control safety of important cities and areas mentioned above were guaranteed effectively by the preliminary joint operation practice of the cascade. Meanwhile, the flood control benefit of joint operation was remarkable. The research and practice can provide favorable references for the similar cascade reservoirs in the world
