Water is one of the basic natural resources for all living things on earth and plays a vital role in providing meaningful socio-economic development. It is used for irrigation, industry, household, agriculture and vegetable growth. The community of the area is currently getting water from boreholes and springs. People practicing irrigation purpose using motor pumps from selala River and springs which found in different part of the catchment. The main objective of this research was to investigate ground Water potential of the study area using electrical resistivity and magnetic geophysical methods. For that study, the symmetrical schlumberger array which is the vertical electrical sounding (VES) was conducted along two lines which are about 150m apart. The magnetic data collection was started and ended by taking base station readings. At each station the magnetometer reading, recording time and its location in UTM coordinate were recorded. The interpretations of VES data was conducted by modeling the VES data, by constrain geo- electric section and by using pseudo section map. The magnetic field data was interpreted using total magnetic field anomaly map, analytical signal anomaly map and upward continuation anomaly map, and Tilt Derivative of Analytical Signal Map.The geo-electric sections show that the area has five main types of litho-logic unit, which has different thickness, and depths of burial. In general, the geophysical survey that was carried out in this study was successful to determine depth, resistivity and thickness of the aquifer present in the study area.
