WeChat public number is one of the important channels for water conservancy information dissemination and user interaction. Based on the perspective of intelligent governance, we systematically analyse the types and forms of WeChat public account and other dissemination data of the seven watershed management agencies under the Ministry of Water Resources, and analyse the dissemination status and the real dilemmas of WeChat public number of the river basin management agencies. The results of the study show that the official WeChat public numbers of the seven major river basin management agencies can actively respond to social concerns, and play an irreplaceable role in disseminating major conferences and industry policies, but there are also difficulties such as hollowing out of the governmental functions and barriers to resource sharing. To this end,it was pointed out that the water conservancy industry in the construction of new media need to further grasp the laws of communication,to create integrated media matrix,strengthen the interaction of government affairs and innovative mode of expression.
