This study examines the small hydropower potential of River Iyi-Ukwu in Oshimili North Local Government Area of Delta State, Nigeria as a renewable energy source. The discharge (m³/s) of River Iyi-Ukwu was well investigated using the Velocity - Area method while using segment method to obtain the depth of the river with which the river profile was drawn. The head from source to destination of the river was approximated from a topographic map of Onitsha in Anambra State, Nigeria. The results show that theoretical power of about 1.83 MW of electricity is realizable from the river on a discharge of 2.887 m³ /s and a head of 76.2 m. This amount of power can go a long way in solving part of the energy crisis in Nigeria especially at the rural areas.
