Resumo: In order to analyze the structure and dynamics of the periphytic community in Iraí reservoir, which is considered a eutrophic environment, samples were taken in two seasons: summer (April) and winter (September) of 2002, in littoral areas from three regions of the reservoir (upper, intermediary and lower). Aquatic macrophytes were used as sampling substrates, because they were found in all sampling sites. A total of 297 species was recorded (225 in April, 73 exclusive to this season; and 224 in September, with 72 exclusive taxa). Bacillariophyceae predominated in all regions in both seasons, in number of species as well as in density. There were differences in richness among zones; intermediary and lower regions were more similar, mainly in September. The periphytic algae density differed significantly between seasons (F = 16,48; p = 0,002), with lower values in the summer. No significant difference in density was recorded among zones.
