Lake Ruataniwha

Lake Ruataniwha is an artificial reservoir near Twizel, fed by two canals and the Ohau River to maintain fresh water supply. The water glows turquoise from tiny glacial particles suspended in it, creating a distinctive color that shifts with light and weather conditions.

The lake was created between 1977 and 1981 as part of the Upper Waitaki Hydroelectric scheme, transforming the valley and its water flow. The town of Twizel was built at the same time to house workers, though residents later fought to keep it permanent instead of dismantling it after construction ended.

The lake's name comes from the Maori language, reflecting the indigenous heritage of the region. Visitors gather here to watch waterbirds like grebes and black-fronted terns, which are part of the daily rhythm of the shoreline.

The lake has boat ramps, picnic areas, and rental shops offering kayaks, paddleboards, and pedal boats for visitors. Shallow areas near the shoreline are suitable for families and beginners, while the straight rowing course with eight marked lanes serves competitive events.

The water glows in an intense turquoise that does not occur naturally, created by glacial flour from surrounding mountains that hangs in the water. This unusual color makes the lake a favorite spot for photographers seeking a landscape that looks almost unreal.
