Rivers flowing down from the Southern Alps of New Zealand’s South Island release sediments into the Pacific Ocean. One of the most noticeable of these is the Waitaki River (center of coastline), fed by streams issuing from Lakes Ohau, Pukaki, and Tekapo (left to right) in the Mackenzie Basin. Here, those lakes appear bright blue amidst the snow-capped peaks of the Alps.

The Waitaki River drains a 4,565-square-mile (11,823-square-kilometre) basin, flowing southeast for 130 miles (209 km) to enter the Pacific at Glenavy, about 70 miles (113 km) north of Dunedin. The Waitaki River Power Development, which includes several large dams, is one of the largest hydroelectric projects in the nation.
