This area is located in border of the Lakes Region and 60 km from province of Isparta. The size of the watershed is 4928.5 ha and average elevation is 1664 m. The main purpose of the study is to develop suggestions to sustainable management of natural resources in the watershed. For this purpose it was evaluated to habitat conditions, to utilized the erosion indicators to the current state of erosion, to indicated the potential of natural resources of the watershed. In the study, therefore, has made a literature review in content of the bureau, field and labotarory studies, proved documents related to the study from relevant institutions, made texture analysis in the laboratory and used the geographic information systems and the participatory approach methods. In the study has been determined that the area has high erosion risk, however in the current state there is no problem resulting from intensive land use. On the contrary, the watershed has a risk in terms of water yield because the area has not been dealt with principles of watershed management. Thus, the watershed needs to verify cooperation between institutions, to determine in terms of water yield using integrated conservation principles.
