Fish type

Rainbow trout

Situation Although a natural lake, Rotoaira has been extensively modified for hydo electric generation purposes and water is diverted to it to be used at times of peak generation. It lies about 20 minutes drive south of Turangi and requires a separate fishing licence as well as the usual Taupo licence to fish it.

Because water is diverted into Rotoaira during times of low electicity demand and then diverted to the Tongariro Power Station during times of peak demand, the lake levels fluctuate and there can be different currents at different times at inlets and outlets to the lake. Rotoaira is a shallow lake. The large amount of weed around the margins produce good food for the large population of rainbow trout. This lake was used as a venue for the 28th World Fly Fishing Championships.
