During this survey some physico-chemical properties of Lower Lake, Bhopal was investigated to assess its water quality status. Water samples were collected from four different stations of Lower Lake on a seasonal basis. Physico-chemical parameters which were analysed throughout the study include Atmospheric Temperature, Water Temperature, pH, Total Dissolved Solids (TDS), Turbidity, Electrical Conductivity (EC), Total Alkalinity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). Pearson’s correlation coefficient (r) value is decided using the matrix to identify the highly correlated and interrelated water quality parameters. It had been found that the general water quality of Lower Lake is contaminated and not safe for irrigation and drinking purpose at all the sampling stations. The main sources of pollution in this lake are sewage, agricultural runoff and other anthropogenic activities.
