The Copperfield Dam (also known as the Kidston Dam) was constructed to service the Kidston mine site in the 1980s. The Dam has a capacity of 20,400ML and is built on the Copperfield River which, in turn, connects to the Einasleigh River. The Dam overflows seasonally and discharges approximately 60,000ML of water per year down the Copperfield River.
Ownership of the Dam transferred to the State upon the closure of the mine. The Dam itself is located approximately 18km south of the Kidston site and is connected to the mine via a gravity fed pipeline. Genex Power owns the pipeline and has the right to draw up to 4,650ML of water from the Dam per annum.
The Copperfield Dam and the existing water rights held by Genex Power will ensure water adequacy for supplementing the Kidston scheme in the event of a prolonged drought event.
