It is located on the artificial Ohau canal. The dam is fed by water from Lake Ohau and Lake Pukaki and spills into the artificial Lake Ruataniwha.[1]

Ohau A has a net head of 59 metres (194 ft). It is part of the Waitaki hydro scheme which consists of eight power stations operated from a control centre near Twizel. Construction of the power station commenced in 1971.[1]
