Abstract: The water quality parameters of Ombi Stream were evaluated for a period of four weeks to investigate the level of the pollutant load at three selected sites. Physico-chemical analysis of Dissolved oxygen (mg/L), free Dissolved carbon dioxide (mg/L), Hydrogen ion concentration (pH), Water temperature (˚C) and Depth (m) revealed a significant difference (p<0.05) among the selected sites and found to be within recommended tolerable limits for the survival of most aquatic organisms. Total alkalinity (mg/L) and Turbidity (m) revealed no significant difference (p>0.05) among the selected sites and were not within the desirable range especially for good fish production. From our results, we can conclude that, pollutants at site III had significantly depleted the water’s vital dissolved oxygen, site I is the best aquatic ecosystem and site II is better compared to site III whose dissolved oxygen is at lethal levels that might hardly support aquatic life.
