Limnological studies of the perennial waterbody, Govindgarh Lake district Rewa (M.P.)

Abstract

This paper describes the physico-chemical profile of perennial lake of Govindgarh, Madhya Pradesh, where limnological studies were conducted during March 2020 to February 2022. Variables analysed from surface water of the tank were temperature, transparency, pH, electrical conductivity, dissolved oxygen, alkalinity, hardness, chlorides, nitrates and phosphate. The seasonal variations of these factors were studied and interrelationships existing between them are discussed. The pH of water was alkaline. Transparency, EC, hardness and alkalinity were tend to increase during summer and decrease in winter. Dissolved oxygen was maximum during winter and minimum during summer. Dissolved oxygen showed inverse relationship with temperature and EC. Nitrate and phosphate were higher in monsoon and post monsoon, fluctuated directly with dissolved oxygen.
