The minimization of conflicts concerning water use, as well as the security of using it in different ways, depends on appropriate hydric resources management, based on proper legal tools. The best legal tool for making water available for different uses and users, preventing or even solving conflicts, is the grant of rights to use it. For that reason, this research evaluates the uses of hydric resources at the Santa Bárbara River hydrographical basin, Goiás State, Brazil, comparing its water availability and current demand. It was possible to conclude that the instant maximum flow, collected in accordance with granted uses, surpasses the legal available flow and approaches the reference one. Another conclusion is that the previous accumulation of part of the total collected water volumes, made by most users, allows a collection process without conflicts or lack of water. KEY-WORDS: Hydric availability; reference flow; flow permanence curve.
