This research work attempted to show some steps of the evaluation of surface and ground water in Kottuli wetland region, Kerala, India for irrigation purpose. It was noticed that the ground water samples collected in the nearby areas of Kallayi & Korappuzha estuaries and cannoli canal were not suitable for irrigation purpose. Wilcox diagram indicated that the majority of surface and groundwater of Kottuli wetland is good for irrigation purposes. Sodium hazard and salinity hazard is low for surface water samples while little high in few ground water samples from USSL diagram. The results obtained from this research make it possible to evaluate the suitability of surface water for irrigation and to draw useful recommendations for the policy makers and farmers.
