| The present study is aimed at assessing the changes in the water quality parameters of Kolar Reservoir of Bhopal, Madhya Pradesh after a time period of 10 years. The first analysis was conducted in the year 2007-2008. The second analysis was done in the year 2017-2018. The parameters included for study are pH, Turbidity, Biological Oxidation Demand (B.O.D.), Dissolved Oxygen (D.O.), Electrical Conductivity, Total Alkalinity, Total hardness, Nitrate and Phosphate. This comparative study will help in the overall assessment of the present condition of the water body. In the present study the Total Alkalinity and Electrical Conductivity has increased when compared to that of 2007-08. Thus, indicative of the fact that there is a strong relationship between these two parameters and even though all the other water parameters showed improvement after a gap of 10 years but still at some points there is certain amount of solvency of salts mainly due to human activities.
Keywords: Electrical Conductivity, Total Alkalinity, Analysis, Turbidity, Comparative.
