Upper Lake of Bhopal is the chief source of potable water for the people of Bhopal. To assess the quality of water of the Lake samples from ten different stations with varying catchment area activities were collected. The catchment area activities ranged from rural to semi urban and urban. The study was carried out for a period of two years during the pre-monsoon and the post-monsoon seasons so as to depict the effect of rainfall upon concentration of various parameters. The various physic-chemical parameters studied were temperature, pH, conductivity, chloride, nitrate, phosphate, sulphate, carbonate, potassium and sodium. It was observed from the study that most of the parameters were found to have a higher level during the post monsoon season due to surface runoff from the nearby areas. Also it was observed that concentration of various parameters depended on the rural and the urban activities being carried out in the catchment area.
