Abstract: Phytoplankton is the pioneer of an aquatic food chain. The phytoplankton has great significance in the biology of the creek as they provide the food for the organisms, especially for Zooplankton. The productivity of an aquatic environment is directly correlated with the density of plankton. The plankton population in any aquatic system is biological wealth of water for fishes and constitutes a vital link in the food chain. The present study was undertaken to investigate the plankton diversity in Sonegaon lake of water area of Nagpur city having distance approximate 7.5 kms. from zero mile, through this three-season taken for study during the period of February 2018 to January 2019. Four major groups of phytoplankton (Myxophyceae, Bacillariophyceae Chlorophyceae and Euglenophyceae.) were studied for diversity and seasonal abundance. Among the groups of phytoplankton, the population density showed variations due to their ad ptability to seasonal changes in water quality. Some plankton population disappeared at a specified period and reappeared during other period. This disappearance may be due to the fact that some species occur in spores, under favourable conditions spore germinate and appear as plankton. Assessment of lake water bodies with reference to species diversity of flora was done in three different seasons’ summer, monsoon and winter. Species diversity of Myxophyceae, Bacillariophyceae Chlorophyceae and Euglenophyceae were recorded. The result indicates the abundance of phytoplankton and high level of primary energy which is subjected to sustainably development of lake utility.
