  Water is most important in shaping the land and regulation of the climate. It is one of the most important compounds that profoundly influence life. The quality of water is usually described according to its physical, chemical and biological characteristics. Rapid industrialization and indiscriminate use of chemical fertilizers and pesticides in agriculture are causing heavy and varied level of pollution in aquatic environment leading to deterioration of water quality and depletion of aquatic biota. Due to use of contaminated water, human population suffers from water-borne diseases. It is therefore necessary to check the water quality status. The objective of this Assessment was to determine physio-chemical and biological status of Shihu Lake and Grand Canal. A sample was collected to determine the Dissolved oxygen and micro-organism in laboratory by using Winkler method and microscope respectively. Temperatures, PH and transparency of water were measured and evaluated on site at water bodies. The Dissolved Oxygen of the Grand Canal and Shihu Lake is 12 mg/l and 10.44 mg/l at depth of 35 cm and 25 cm respectively. Under the microscope different microbes were found like cyanobacteria, fiber algae and insects. The average of secchi disk of transparency is 55.5 cm and 59 cm respectively at Grand Canal and Shihu Lake. Constant temperature and pH were recorded at 20.0oC and 8.0 pH for both Grand Canal and shihu Lake respectively. The waters content of both sites was in stable natural condition. The presence of few microorganisms and some organic substance is an indication that the water ecosystem is balance, but eutrophication can result as nutrient cycle and Algae continue to grow. The concerned bodies should continue to monitor and prevent entrance of untreated effluent to the water bodies as well as control of pollutants from nonpoint pollution sources.
