Law 9.433/1997 is a milestone in the management of water resources in Brazil. It includes as one of its instruments the permit for the use of water resources that aims to assure the quantitative and qualitative control of water use and guarantee the effective right of access to all citizens. The aim of this study was to survey the permits issued by the Secretariat of State for Environmental Development (SEDAM, in the Portuguese acronym) from 2010 to 2019 in the Jaru River basin, in the state of Rondônia, Southern Brazilian Amazon, as well as identify the different users and the purpose of use of superficial and groundwater. This information was organized in tables and graphic representations and georeferenced for the elaboration of spatial maps of the permits. The results allowed us to identify the water users of the aforementioned basin. It also indicated that most of the permits refer to superficial water (84 %) and that 79% of this is used for fish farming. The permits issued for the use of groundwater of the basin present a smaller total, and domestic use is the main purpose of these waters (48%), followed by industrial use (44%). The study also mapped the deforestation in the area related to this study until August 2019 through the Deforestation Program (PRODES, Portuguese acronym) of the National Institute of Space Research (INPE, Portuguese acronym) due to the expressive number of projects of the National Institute of Colonization and Land Reform (INCRA, Portuguese acronym). Considering the great anthropization of the basin and its negative impacts on the waters, a number of actions are essential. For example, the establishment a committee for the Jaru River Basin – Baixo Machado/RO; the launch of an awareness campaign about the rational use of water and a campaign to regularize the record of water users in the water resource management body in Rondônia. This will allow this collegiate, which nowadays is only legally instituted, as soon as it is implanted, to prioritize recovery actions of degraded areas such as the riparian forests and increasing lack of water during the dry season, acting in the mediation of conflicts between the water users.
