The main aim of this research work is to analyse Phytoplankton abundance and its impact on water quality of the Pravara River water, for which water samples from 08 sampling stations from stream have been collected during 1st week of Jan 2022. Physico-chemical parameters have been analyzed by standard method. The Field observations reveal that enhancement in human activities water deterioration also increased. It is all due to indiscriminate behaviour of the human being. Many human activities necessary for survival but it declined water quality. Study also reveals that in the study area due to deterioration of water quality phytoplankton abundance has been observed. At the dadh, Ashwi, Punatgaon, Toka due to phytoplankton water is not fit for drinking purpose. To analyze Phytoplankton abundance and Physio-chemical characteristics of water is the main aim of the research with remedial measures to mitigate the deterioration and related consequences in future. Keywords---Pravara River, Phytoplankton, Water Quality, Physico- chemical Analysis. Introduction Now-a-days everyone is worried about pollution of rivers, which is cause by extensive use of fertilizers and chemicals in the field of agriculture and development of various industries (Kumar et al.2007). The most important serious problem is liquid and solid waste material due to which water surface gets
