This Paper present to study of the assessment of spatial and seasonal water quality of Nyabarongo using physicochemical parameters. Monthly variation in physicochemical such as water temperature, pH, dissolved oxygen, biological oxygen demand after 5 days incubation, chemical oxygen demand, total phosphorus, soluble reactive phosphorus, total nitrogen, ammonium and nitrate were analyzed for a periods of one year from 1st January 2015 to 31st December 2015 using standards method for water analysis. Low values are recorded at the site of Kabirikarhaba except for pH, DO and COD. All parameters were within the permissible limits for aquatic life. The results indicate that the variations are observed during the year and from site to site.
