The Huka Falls are a set of waterfalls on the Waikato River that drains Lake Taupo in New Zealand. A few hundred metres upstream from the Huka Falls, the Waikato River narrows from approximately 100 metres across into a canyon only 15 metres across.
The volume of water flowing through often approaches 220,000 litres per second. The flow rate is regulated by Mighty River Power through the Taupo Control Gates as part of their hydro system planning, with Waikato Regional Council dictating flows during periods of downstream flooding in the Waikato River catchment.
At the top of the falls is a set of small waterfalls dropping over about 8 metres. The final stage of the falls is over a 6-metre drop, raised to an effective 11m fall by the depth of the water. The falls are a popular tourist attraction, being close to Taupo and readily accessible from State Highway One.
