Bacillariophyceae (Diatoms): The species of Cyclotella, Fargilaria, Mastigloia, Gyrosigma, Navicula. Pinnularia, Cymbella, Rhopalodia, Nitzschia and Surirella are found during investigation at all sites of study area. Diatoms showed luxuriant growth in winter and summer seasons. Water of Isapur is the home to a very rich biodiversity that constitute part of natural resources. However, over the past years, there has been an observed decline in aquatic biodiversity in most of water bodies. The phytoplankton has great significance in the biology of the creek as they provide the food for the organisms, especially for Zooplankton. The phytoplankton has a great significance in the biology of an estuary as they provide the food for other organisms, especially the zooplankton. Further, physicochemical factors of water are directly related to their production. The present investigation is an attempt to study the Phytoplankton community of Isapur dam water, the present dam is situated on the river, namely Upper Painganga and Lower Painganga. Also this dam is known as 'Isapur Dam'. This dam is administered by the 'Pusad' taluka. Nearby talukas are Kalamnuri, Pusad, Umarkhed and Hadgaon. During the study the total number of Phytoplankton was counted about 100 species were recorded. The Bacillariophyceae were found to be dominant throughout the study.
