The present study aims to assess the surface water quality in Surha Lake using CPI, OPI, EI and TPI with respect to drinking water, during wet and dry seasons in the year 2014-15. The results indicate that water quality in the lake is moderately polluted and eutrophic i.e. in CPI range 1-4 and EI>1. The TPI was found in the range TPI >1 which signifies the severely contaminated lake water due to trace metals. Therefore, the lake water is not suitable for drinking and it is suggested to do prior treatment of lake water before use. It is recommended to the concerned authority to prepare and implement a proper monitoring program and carry out conservation strategies to restore the water quality of the lake and reduce its ill effects.
