The Lancang Mekong River Basin (LMRB) has been threatened by flooding for millennia. However, joint actions for basin wide reservoirs flood control is still lacking due to complex flood processes and multi involved stakeholders, facing both technical and social challenges: identifying the core reservoirs incorporated into joint action, investigating the effectiveness of joint action, and furthermore exploring the contribution of the riparian countries.

Our study addresses the gap in exploring basin wide flood control capacity and provides reference for joint action, with the support of the CHRJOM.

• Con-based method is proposed and proven as efficient tool in identifying the core reservoirs.
• Twenty six core reservoirs are identified for joint operation, which could basically control the frequent floods within the levee’s safety standard.
• China and Laos emerge as predominant contributors.
