A major feature of the upper Waitaki hydro scheme is the canals which link and combine the resources of Lakes Tekapo, Pukaki and Ohau.
These canals have a total length of more than 58 kilometres. Their construction required the excavation of nearly 45 million cubic meters of spoil.
The canals allow fishing all year round. The Upper Waitaki hydro canals are yielding bigger and bigger trout, with a staggering 20.5-kilogram (45 pound) brown landed recently.
