Abstract
Plankton, physical, chemical, and microbiological data, were taken fro m the polluted reservoir El Niagara during 1990. Chlorella spp and Eug lena spp were the dominant phytoplankters. Zooplankton diversity and d ensity were low: Brachionus spp, Asplanchna sieboldi, Moina affinis an d Daphnia similis appeared seasonally; protozoans were present all yea r. Ten years earlier, the water quality and biota of the reservoir, th en alreay degraded, were much better than today.
