Water quality and permanent monitoring are essential for understanding the integration processes that occur between the uses of the basin. Continuous monitoring of existing water quality in water resources becomes a powerful tool to manage in advance environmental problems that may arise when the results point to non-compliance with the competent national legislation. This research aims to analyze the morphometry and quality of water used and occupied in the Piranhas-açu watershed in the State of Rio Grande do Norte, and compare the averages obtained with the values in force in CONAMA Resolution nº 357/2005, of class II. The chemical, physical and biological parameters of the waters of the Pataxó reservoir were analyzed. In this study, data referring to the period from April 2018 to June 2019 were considered. The results obtained showed that all parameters analyzed are in compliance with what is established by the legislation and nonconformities that are not specific for dissolved oxygen can be highlighted. -OD and biochemical oxygen demand-BOD and nickel with values above the allowed.
