A re-inforced concrete arch dam was constructed in One Mile Creek to divert water into a penstock that supplied a pelton wheel turbine in a powerhouse constructed near to the shore of Lake Wakatipu.
The station was officially opened on 18 September 1924[1] and operated until 1966 when it was decommissioned.
The headworks of the scheme were subsequently used by the Queenstown Borough Council for water supply purposes.
[2] A charitable trust was formed in 2002 to undertake restoration of the building and re-instatement of the generating equipment as a heritage project, and the work was completed in 2005.
[2] The One Mile Creek Walk generally follows the steep route of the penstocks from the powerhouse up to the dam.
