Evaluation of water quality index of Upper Lake - A Ramsar site

During the present survey some physicochemical properties of Upper Lake, Bhopal were investigated in order to assess its water quality status. Physicochemical parameters which were analyzed throughout the study include pH, TDS, dissolved oxygen, total alkalinity, total hardness and nitrate. It was found that the overall water quality of Upper Lake comes under ‘Fair’ to ‘Poor’ quality at all the sampling stations. The major sources of pollution in this lake were sewage, agricultural runoff and other anthropogenic activities.
