Hydro-geoelectric study has been undertaken within the Smoking Hills Golf Resort Ilara-Mokin, Ondo State.The golf resort is situated on the Crystalline Basement Complex rocks of Southwestern Nigeria with the lithology consisting of variably migmatized Biotite-Hornblende-Gneiss with intercalated Amphibolite and Quartzite.The study involved the Direct Current Electrical Resistivity method of geophysical prospecting.The field technique adopted is the vertical electrical sounding (VES) utilizing the Schlumberger configuration.Twenty five (25) VES stations were occupied within the study area.The sounding curve types obtained from the field data are KH, H, HKH, KQ, AK, KQH, AKQ, K and KHK.The sounding data presented a lithologic sequence consisting of the topsoil, thick weathered basement, partially weathered/fractured basement and the fresh bedrock.The overburden materials within the golf resort which are generally in excess thickness of 21.8 m with maximum thickness of 120.9 m constitute the main aquifer units with possibility of fairly adequate yield at twenty one VES locations.A combination of overburden materials and the partially weathered/fractured basement constitute aquifer units with fairly adequate yield at three VES locations while the partially weathered/fractured basement constitutes the main aquifer unit at one VES point.The groundwater potential of Smoking Hills Golf Resort is of low ranking beneath two VES locations (VES 15 and VES 20) and of medium ranking beneath the remaining twenty three (23) VES locations.
