The water qualities of three rivers (Asu, Ebonyi and Cross) were evaluated for these physicochemical parameters: transparency, flow rate, depth, temperature, conductivity, total dissolved solid (TDS), pH, dissolved oxygen (DO), phosphate (PO4-) and nitrate (NO3-) for 12 months (August 2014-July 2015). The results showed variations in the water quality parameters among the rivers. Temperature, conductivity and TDS were highest in Asu River with mean values of 30.23 0 C, 88 µS/cm and 42.58 mg/L, respectively. The mean values of pH varied from 7.0 to 6.56 with the highest value (7.0) recorded in Ebonyi River and the lowest value (6.56) recorded in Mid-cross River. The mean value of DO was highest (5.8 m/Ll) in Mid-cross River and lowest (4.9 mg/L) in Asu River. The lowest mean values of transparency, flow rate and depth were recorded in Asu River, the highest (0.5 m) mean value of transparency was recorded in Mid-cross River while the highest mean value (1.48 m) of Flow rate was recorded in Ebonyi River. Variations in the mean value of nutrient in the water showed that PO4-(0.28 mg/L) and N03-(0.40 mg/L) were the highest in Asu River. The lowest PO4 was recorded in Ebonyi River (0.17 mg/L) while the lowest NO3 value was recorded in the Mid-Cross River. Variations in Temperature, DO, Flow rate and PO4 were not significantly different (P > 0.05) while conductivity, TDS and transparency were significantly different (P < 0.05). The results of most water parameters recorded are within the recommended limits of set standards for rivers.
