The country's water potential allied to the new politics of incentive to the reorganization of the energy potential stimulates the private initiative for the production/generation of energy in alternative matrices. In this context are inserted the Small Hydroelectric Plants - SHP, enterprises with lower costs of implantation and minors socio-environmental impacts. One of the legal requirements for the implantation of these enterprises is the accomplishment of studies that demonstrate analyses of the interactions of these enterprises with the environment and the respective measures of control and mitigation of the environmental impacts. Therefore, it was executed the quality evaluation of the waters in fractions of the São Tomás River, in the city of Rio Verde at Goiás southwest, as part of the necessary environmental studies for the installation of four SHP, four points of the river hydropower exploitation. It was intended with this evaluation to define the profile of the water quality of this water course previously the installation. For the evaluation was used the correlation between different methods of quality analyses: the application of the protocol of fast ecological evaluation, evaluation by bioindicators collected at the sampling spots, physical-chemical and bacteriological analysis and use of Water Quality Index - WQI.
