Phytoplankton analysis and assessment of reservoir water quality at Rena Medium Reservoir, Godavari Basin, India

Abstract

One of the greatest environmental issues is phytoplankton development in reservoirs. Reservoirs, and other bodies of water used for residential uses with minimal water circulation support the most intense phytoplankton development. This process results in a severe decrease in potable water quality and an increase in the overall amount of hazardous chemicals in water. The variance in the growth of phytoplankton species must be determined to monitor the status of water quality. Moreover, an appropriately designed and operating system of data collection and analysis is urgently required for the improvement of the existing setup for water quality monitoring of reservoirs. The present investigation is conducted to know the rate of variation in the phytoplankton population of 'Rena Medium Reservoir', Godavari Basin, Maharashtra, India. The research analysis and assessment is conducted for a period of six months from December 2021 to May 2022 comprising winter and summer seasons with five sampling sites in three different zones of the reservoir. The water quality is affected by dilution during monsoon and the high evaporation rate during summer. There is fluctuation in the reservoir water quality at the same monitoring locations. These variations are attributed to the increasing influence of anthropogenic activities. This analysis assessment helps the authorities to identify the best and most sustainable uses of the reservoir and decide the future course of the Godavari River Basin.
