The long-term biological monitoring data in domestic streams need to be appropriately analyzed. Food-web analysis using network-based approach can give ecological implications on these kinds of data by including interactions between species. The purpose of this study is constructing food-webs as a preliminary step of the analysis. We used observed species list data for 8 years (2008-2015) provided in Water Information System (WIS), focusing cheonggye streams as a case study. On the basis of species interaction dataset extracted from Global Biotic Interactions (GloBI) database, 96 food-webs were constructed. In further studies, these food-webs could be analyzed in various ways such as static, dynamic and spatial approaches.
