Chimdi Lake has ecological significance as it has been a home for several associated biodiversities. A study was carried out to investigate the pollution status by analyzing some important physicochemical parameters of Chimdi Lake. The parameters analyzed were ambient temperature water temperature, Turbidity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Conductivity, Hydrogen- ion-concentration (pH), Dissolved Oxygen (DO), Total hardness (TH), Chloride, Nitrate – Nitrogen (NO3-N), Phosphate- phosphorus (PO4-P), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) and fecal coliform. On the basis of pollution status found, the water of the lake was unfit for drinking purposes.
