Comparative assessment and seasonal variations of some physical and chemical parameters of waters in Ekerekana and Buguma creek were investigated from July 2012 to February 2013 for a period of eight months. Water samples were collected bi-monthly and analysed using standard methods. The results obtained indicated that significant differences (P<0.05) were recorded in all the parameters investigated in both creeks in all the months of study. Seasonally, variations were observed in all the parameters, with the exception of pH, alkalinity, and water hardness. Conversely, temperature, conductivity, salinity and nitrates were significantly (P<0.05) higher in dry season in both creeks, while the values of biological oxygen demand, turbidity, total dissolved solids (TDS), sulphates and chlorides were elevated in wet season.
