Aratiatia Rapids

Before construction of the dam and hydro station, the Aratiatia Rapids were a prominent feature on the Waikato River; a scenic reserve from 1906. The dam construction meant that no water flowed over the rapids. However, several times a day, the Aratiatia dam gates of the Waikato River are opened, which restores the rapids to their normal operation. There are several public lookout points on the high rock bluffs that dominate this turbulent stretch of Aratiatia Rapids.
