Phytoplankton are a major source of primary production in aquatic ecosystems and constitute one of the most important assemblages of the biotic community. These organisms are the basic level of the trophic pyramid upon which other organisms are dependent. The development, maintenance, and environmental influence of phytoplankton in and on the aquatic ecosystem has been a subject of interest and concern for many years. Most of the studies concerning the nature and distribution of phytoplankton have been confined to lacustrine systems. Hutchinson (1967), citing several lake studies, sutmarized various aspects of the physical and chemical factors associated with phytoplankton. These studies have limited, application to riverine systems.
