The spatial analysis of declination nature of groundwater level for ninety eight (98) wells monitored between March 2004 and February 2006 was carried out using Geostatistics. The data for the groundwater levels were analysed in order to accounts for the spatial variability of the phenomenon. The result of the experimental variogram that characterise the spatial variability showed a low nugget-sill-ratio which implies a strong spatial correlation. A theoretical variogram was used to fit the experimental variogram and to obtain the range of influence. Ordinary Kriging and cross-validation were used to map the spatial variability of groundwater declination and to asses the accuracy of the theoretical model respectively. The result of the Kriged map showed a high declination in groundwater level around the northeast to the southern part of the study area.
