Abstract: This study seeks to investigate the Physico-chemical parameters of Karidna Reservoir in Igabi Local Government Area of Kaduna State. The investigation was carried out for a period of one year between October 2013 and September 2014. Five sampling stations were chosen. The physicochemical parameters were determined using standard methods, procedures and instruments. The results showed that pH had a range 6.19-8.63,Temperature 25.94-31.54 oC, Electrical Conductivity 38.20-64.20µS/cm, Total Dissolved Solids 19.20-37.20 mg/l, Transparency 19.40-40.10 cm Dissolved Oxygen 2.40-6.81mg/L, Hardness 3.48-174.4mg/L Calcium 2.14-3.86mg/L, Biological Oxygen Demand 2.91-40.85mg/L, Chloride 2.28-3.58mg/L Phosphate-phosphorus 0.04-0.24mg/L, Nitrate- Nitrogen 0.14-0.30mg/L, Sulphate 0.06-0.21mg/L and Alkalinity with 2.51-5.04mg/l. Phosphate-phosphorus, Nitrate- Nitrogen, Sulphate, Electrical Conductivity, Total Dissolved Solids, Transparency, Dissolved Oxygen and Biological Oxygen Demand were highly significant at (P<0.01) between the seasons while non-significant differences were observed in Chloride, Hardness, Alkalinity, Temperature and pH.. Calcium was the only parameter that was significant at P<0.05. Non-significant differences were obtained across the stations. All the physico-chemical parameters revealed monthly and seasonal variations across stations.
