Slope is very important in identifying the groundwater recharge zones of the watershed. Because it impacts the runoff speed, runoff retention on the soil surface as well as infiltration capacity. Flat areas are very good for groundwater recharge capability since such areas influence high infiltration rates and less generation of surface runoff. However, areas with steep slopes have low groundwater level since less time is allowed for stormwater to infiltrate, thus rainfall is easily turned into runoff and rapidly flow down the slope. Generally, gentle slopes are prospects of high groundwater potential, more rainfall can percolate into the subsurface. Rainfall is the main source of groundwater, slope gradient directly affects the infiltration of rainfall into the ground. The slope of the watershed was grouped into four classes to groundwater potential as; ‘very poor’ (14.88 – 44.6%), ‘poor’ (7.88-14.87%), ‘good’ (3.16-7.87%)and ‘very good’ (0-3.15%).
