Abstract
In this paper the author presents the results of the research carried out over several years on the composition of main primary producers of a dam reservoir on Bistriţa River. As a consequence of the developing of a rich and various aquatic macrophyte community, a lot of periphytic algae populated this microbiotope. This resulted in a significant increase of biodiversity in this man-made lake.
