Groundwater is the most tapped fresh water source. Timely availability is the reason for its reliability. Temporal groundwater fluctuations are quite natural aspects perhaps never be ignored hydrologically. This work demonstrates the heterogeneity in groundwater levels and predicts the levels for a small agrarian catchment for a rivulet named Ujire Halla. About 25 water wells, distributed well within the watershed, have been observed regularly to understand the groundwater health. So sampled 6-week data, falling in November to March, is interpolated to the extents of watershed. The spatial interpolation has been carried out using a well worse method, called Kriging. The accuracy of Kriging in every prediction is expressed by variance. The results obtained infer about the ground water fluctuations. The fluctuations are more in the northwest to the core parts of the catchment. Fluctuations are also affected by the alternate source of water supply arranged by local bodies. Further, with the availability of spaces one can practice rooftop rainwater harvesting or the runoff can be recharged to the openwells to level the fluctuations.
