The Splityard Creek Dam is located in hills adjacent to Lake Wivenhoe and is about 100 metres (330 ft) above it.

The pumped storage hydroelectricity power station consists of two circular concrete silos, each of about 32 metres (105 ft) internal diameter.

[4] During the pumping phase in the operating cycle the generator operates as a 240 megawatts (320,000 hp) electric motor driving the pump to lift water from Lake Wivenhoe to the upper storage of the 28,600-megalitre[1] Splityard Creek Dam.

[2] The Splityard Creek Dam has sufficient capacity for 10 hours of continuous power generation.

[7] Twin 275KV transmission lines connect the power station to Queensland's grid system.
