The paper describes the problems related with eutrophication in water supply reservoirs. One of the most relevant impacts
is the growth of cyanobacteria, which are able to generate very powerful toxins. This situation is more critical in tropical
regions, where all metabolical processes are faster and where generally there is lack of financial resources for implementation
of adequate monitoring programs. A case study(Vargem das Flores Reservoir) is presented, with emphasis on the
study of eutrophication development based on N/P relationship. It was found that low N/P values did not favour here the
dominance of cyanobacteria, as generally reported in the technical literature. The paper also discusses the adoption of
some preventive and corrective techniques for avoiding cyanobacteria blooms in water supply reservoirs.
