Resumo: The aim of the present study was to investigate the structure and dynamics of the phytoplankton in the Botafogo reservoir-PE-Brazil. Phytoplankton assemblages were identified from current literature and density was estimated using an inverted microscope. Concurrently to the sampling of biotic variables, measurements of abiotic parameters, such as water temperature, dissolved oxygen and pH, were determined using field probes and transparency was determined with a Secchi disk. Total phosphorus and total nitrogen concentrations were determined in laboratory. A total of 24 taxa were identified. Chlorophyta presented the greatest number of species. Species diversity in the reservoir was low throughout the study period. Principal component analysis revealed that Trachelomonas volvocina, Chlorella vulgaris, Euglena sp. and Peridinium gatunense were directly correlated with oxygen, turbidity and total nitrogen; Planktosphaeria gelatinosa, P. gatunense and Euglena sp. were directed correlated with total nitrogen; rainfall explained the occurrence of Monoraphidium arcuatum and Chlorella vulgaris.
