This paper aims to analyze the use and occupation of the surroundings of the public reservoir of the municipality of Riacho da Cruz (RN), in order to discuss the planning and management of water resources. Visual classification of images was performed by Geographic Information System (GIS), employing the software Qgis v. 2.14.11 for photointerpretation, and vectorization. To make the map of use and occupation it was considered a 500m buffer from the reservoir edge. It was identified the classes native forest (69%), lowland vegetation (5.7%), urbanized area (3.2%), among others. It was observed that the urban presence in the surroundings could interfere in the reservoir quality. Therefore, it is relevant to plan and manage this area to minimize the impacts of anthropic actions and to assist in the integrated environmental management.
