Geoelectrical investigation was carried out in Otuo Community of Edo State, Southern Nigeria, with the aim of delineating the best aquifer bearing zone, and as well the vertical and lateral variation of subsurface lithology with depth and distance respectively. Schlumberger electrode configuration was employed in obtaining four (4) VES data. In determining the capacity bearing rating and groundwater potential of the area, the Dar Zarruk Parameters were tools used in characterizing the aquifer viz: Resistivity Contrast (RC), Resistivity Reflection Coefficient (RRC), Total Transverse Resistance (T) and Total Longitudinal Conductance (S). From the results obtained, VES 3 is the showed high potential source for groundwater compared to other VES points. It has the highest T value of 73,050.27 Ωm2 (showing a very good transmissivity of the layer), RC (3.045) and RRC (0.500), however, all parameters fell within good prospect for groundwater development. VES 1, 2 and 4 having values of 4787.22, 4003.95 and 28106.1005 (ohm-m2) respectively. The results obtained also show that VES 3 had the highest fracture thickness of 61.26 m meaning it has the highest groundwater potential, since VES 1, 2 and 4 having values of 22.02 m, 27.34 m, 48.91 m respectively.
