Hydrobiology is the science of life and life processes in water. One of the significant areas of current research is Eutrophication. Special attention is paid to biotic interactions in the reservoir. Biological assessment is a useful alternative for assessing the ecological quality of aquatic ecosystems. The study of phytoplankton is an important aspect of aquatic biology. Aquatic floral species are very sensitive and in a given aquatic body, these species serves as a indicator to pollution Phytoplankton species respond to physico-chemical factors and tend to represent variously in a given time. In present paper it was an attempt to study the group of such species and their seasonal presentation in relation to physico–chemical factors. Derala Reservoir Tq. Loha Dist Nanded was selected to analyze physico- chemical parameters in relation to pollution indicator species noted. This study was carried out during the period 2017-2018. The study revealed that there was significant seasonal variation in physico-chemical parameters, which correlates with the distribution of pollution indicator species .Most of the parameters in the present. Study were in acceptable range and from the result it is concluded that the reservoir remained semieutrophic
