An assessment of the physical characteristics of industrial wastewater discharge into Kaduna River was carried out. Daily concentration of Turbidity, Temperature, Colour, Electrical conductivity and T otal solids were converted to mean monthly. From the analysis conducted on bimonthly and monthly basis, it was observed the highest mean concentration of Turbidity (143 NTU) was recorded for the bimonthly while (133NTU) was for the monthly. The highest mean Temperature of 31.260C was observed for bimonthly and 31.270C was the temperature for the monthly. The highest mean color concentration level of 38.4H0 recorded for bimonthly while 38.5H0 was for the monthly. The highest mean Electrical conductivity at 3700µs/cm recorded for the bimonthly while 3090µs/cm for the monthly reading was recorded. Total dissolved solids value of 335.1mg/l for bimonthly reading was recorded in August and 272.7mg/l monthly mean concentration was recorded monthly. From the analysis, it can be adduced that Turbidity, color and Total solid concentration increases during wet weather flow mainly due to lateral inflow while temperature and Electrical conductivity concentration increases during dry weather flow.
