About Whangaehu

The Whangaehu River is a large river in the central North Island of New Zealand. Its headwaters are the crater lake of Mount Ruapehu on the central plateau, and it flows into the Tasman Sea eight kilometres southeast of Whanganui. Due to the high acidity of the water coming from the crater lake, water is not diverted from the headwaters for the Tongariro Power Scheme. Instead, it bypasses the Waihianoa Aqueduct via a ford.

Whangaehu in Depth

Geology

The river is often poisoned with toxic chemicals from the volcanic activity in and around Mount Ruapehu. The upper part of the river begins as the meltwater from a small glacier. When hot water from the lake spills, it quickly melts the ice and snow in the glacier forming a cave-like tunnel.
