Abstract
This paper describes the physico-chemical profile of perennial pond of Bansagar, Rewa (M.P.) India, where limnological studies were conducted during Jan. 2020 to Dec. 2020. Variables analysed from surface water of the pond 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 postmonsoon, fluctuated directly with dissolved oxygen.
