Abstract: This study has delineated groundwater potential zones of the Nabogo basin and categorized the northern and eastern 13 parts, representing about 35 % of the total basin, as the most suitable areas for groundwater prospecting. The inhabitants 14 of the basin depend on rainfall and small surface reservoirs for their various water supply needs, which become very 15 scarce and unsustainable in the dry seasons due to the arid to semi-arid conditions of the basin. Thus, groundwater is 16 increasingly being exploited to supplement the water needs of the populace. However, groundwater development in 17 the basin is sometimes hindered by relatively low success rate of boreholes. Therefore, this study was aimed at 18 delineating the groundwater potential zones of the basin to improve on development of the resource for supply to the 19 populace. The methodology used involved acquisition of data on well-distributed boreholes in the basin, computation 20 of transmissivity and specific capacity values from the data, and delineation of potential groundwater zones through 21 integration of borehole yields, regolith thickness, static water level and transmissivity using the weighted overlay 22 technique in a GIS environment. The study results indicate that transmissivity ranges from 0.1 to 535 m2/day with a 23 mean of 19.7 m2/day while the specific capacity ranges from 0.25 to 170.88 m3/day/m with a mean of 13.42 m3/day/m. 24 A groundwater potential map generated categorizes the basin into poor, moderate and high zones covering 652.52 km2, 25 1250.45 km2 and 1002.23 km2 respectively, which would be very useful for groundwater development.
