Famed for its white water and irridescent glacial water, the West coast's Waitaha river is facing threats from a hydro-electric plan that could see its lower gorge de-watered.

Waitaha River
A rugged and remote West Coast river, the Waitaha, is a wilderness and biodiversity treasure. Loved by all who visit, the Waitaha has its upper reaches in the snowy and ice covered Southern Alps. Ivory Glacier feeds an alpine lake, and water tumbles majestically down Stag Creek to the Upper Waitaha.
The river broadens at times to provide important habitat for blue duck/whio, including at the important location of Kiwi Flat. It then pinches and goes through one of the most spectacular gorges in the country – the Morgan Gorge, before emerging to take a short meander to the West Coast’s Tasman Sea. Lying almost wholly within public conservation land, the mecca of the Waitaha has called trampers and kayakers for decades.
NZ Westpower, based on the West Coast, is investigating a number of options on the Waitaha River. Currently it favours dewatering the Morgan Gorge through a weir and pipe system to generate around 20MW of energy. Investigations are ongoing and Forest & Bird is maintaining a watching brief.
