The paper investigates a comparative assessment of water quality of Ikop Lake which is a fresh water lake of Manipur and its peripheral fish farms.Rapid population expansion and corresponding anthropogenic activities of the surrounding villages of Ikop lake play crucial role in contamination of water. It enhances degradation of water quality of this fresh water lake. The level of contamination can be evaluated either from physical and chemical or from biochemical attributes. Present study was undertaken to assess the water quality status of Ikop lake and its peripheral fish farms during June to September, 2022 by using different physiochemical parameters such as, temperature, pH, free carbon dioxide (CO₂), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), total hardness, total alkalinity, chloride, conductivity, turbidity, sodium, potassium, phosphate, total coliform etc. The result values of different parameters showed variations in lake water and farm water. It also indicated deteriorating quality of both water bodies.
