Aratiatia Dam is the first of 8 hydro dams on the Waikato River, which runs from Taupo (middle of the North Island, New Zealand) out to Port Waikato. As part of the resource consent for the dam to operate, they have to preserve the Aratiatia Rapids, which was a famous attraction before the dam was built in the 1960's. In order to do this, they let water through for two half-hour periods each day to re-create the rapids through the short gorge which comes out the other end alongside the outfall from the power station. This series shows the water rising and flowing through the rapids as they open the dam spillway. And a couple of other shots of the same. Note the steam clouds in the distance, which are from the geothermal steam fields in Wairakei and Tauhara. I just had my last day at work today at the geothermal power station, so I thought it was fitting that I slacked off for a couple of hours to take some photos around the place.
