This study explores the structural characteristics of local water management systems in South Korea that enable collaborative watershed management. Previous studies have focused on the establishment and operations of watershed management authorities and watershed governance. This study empirically analyzes the structure of water management in metropolitan cities and provincial governments regarding four watersheds. In particular, using two-mode network analysis, this study analyzes the relationship between local administrative organizations and water policies in relation to watersheds. The results of the analysis are as follows. First, the density and structural patterns of the connection between local administrative organizations and water policies in the four watersheds are similar. Second, the Gyeonggi Water Resources Headquarters and Jeonbuk Water Environment Management Department both administer a range of water policies. Water quality, rivers, and natural disasters are connected with many local administrative organizations. Few differences can be seen among the watersheds. In terms of integrated watershed management, coordination and collaboration are required because the organizations responsible for related water policy in a given sector, such as energy & dam, natural disasters & agricultural disasters, are separated. Public managers should diagnose and manage the appropriateness and effectiveness of the current water management structures, consisting of local administrative organizations and the water policies being implemented in watersheds.
