Waitaki River

The Waitaki River is a large braided river that drains the Mackenzie Basin and runs some 110 kilometres (68 mi) south-east to enter the Pacific Ocean between Timaru and Oamaru on the east coast of the South Island of New Zealand. It starts at the confluence of the Ohau River and the Tekapo River, now in the head of the artificial Lake Benmore, these rivers being fed by three large glacial lakes, Pukaki, Tekapo, and Ohau. The Waitaki flows through Lake Benmore, Lake Aviemore and Lake Waitaki, these lakes being contained by hydroelectric dams, Benmore Dam, Aviemore Dam and Waitaki Dam. The Waitaki has several tributaries, notably the Ahuriri River and the Hakataramea River. It passes Kurow and Glenavy before entering the Pacific Ocean.
