Abstract： Based on the experience of emergency treatment of Baige Barrier Lake in the upper reaches of
the Jinsha River in 2018， the joint emergency rescue work mechanism such as inter-ministerial joint con⁃
sultation，central-local goverments coordination and linkage，emergency response social mobilization and di⁃
saster situation were summarized，and the possible disasters in the the Jinsha River if there is no cascade
hydropower stations joint operation and regulation was deeply analyzed. The results show that without flood
2
regulation of the Liyuan Hydropower Station，the inundation area would be increased about 160 km ，caus⁃
ing greater losses along the river. It is recognized that timely acquisition of barrier lake information is the
prerequisite for emergency disposal， rapid risk assessment is the technolical support， accurate analysis of
landslide dam break flood is the key， the coordination and linkage working mechanism is the guarantee，
the dynamic rescue project management is the scientific method， and the perfect high-dam reservoirs is
the fundamental way to deal with flood disasters. It is further proposed that （a） to strengthen the rapid ac⁃
quisition and processing technology of multi-source information of barrier lake under the condition of lack
information，（b） to strengthen the technical capability of rapid risk analysis and judgment under the condi⁃
tion of little information，（c） to strenghen the research and development of special equipment for emergen⁃
cy disposal of barrier lake，（d） to improve the overall management of emergency rescue projects and the
perfect coordinated linkage system，（e） to strenghen the development of high dams and risk management
and emergency dispatch system. It should provide references for the improvement of barrier lake risk dispos⁃
al technology and the comprehensive disaster prevention and mitigation of the river basin.
