The water crisis does not escape the environmental problem, since, while water is essential for the maintenance of economic processes and maintenance of life, it is also one of the most degraded natural resources by humans, bringing economic, social and environmental consequences . Given this scenario, the objective of the present study was to investigate the state of the water quality of the Gramame-Mamuaba, Marés and Araçagi river reservoirs, located in the intermediate geographical region of João Pessoa, and which serve for human supply. The study was based on the analysis of data on water quality parameters observed in a 12-year historical series, using the CETESB Water Quality Index and Bascarán Water Quality Index, taking into account the effects of seasonality. An improvement in water quality was identified for the three studied river reservoirs for periods of drought. In addition, through an analysis of water quality parameters in comparison with the limits established for Class II type fresh water CONAMA Resolution No. 357/05, which, despite the IQA's being able to effectively express the effects of seasonality, an analysis of the indices individually proved to be more satisfactory to identify the non-conformities existing in the entire historical series of parameters with their respective classes. These results showed the need for greater action by the competent bodies in terms of inspection, awareness and care for the quality of water in river reservoirs.
