Arawhata River

The Arawhata River (often spelt with the Ngai Tahu Maori dialect spelling Arawata River) is in the West Coast region of the South Island of New Zealand.

The river has its headwaters in the Mount Aspiring National Park. It drains the eastern side of the Southern Alps and heads in a northerly direction for 60 kilometres, draining into Jackson Bay. A small lake, Lake Ellery, drains into the river near its mouth, via a short tributary, the Jackson River .

Access is possible up the river by jetboat. Glacial silt in the river imparts an opaque green to greyish coloration to the water. The valley is grazed by cattle by the local farmers under a grazing licence. The majority of the land in the area is publicly owned and administered by the Department of Conservation.

Due to the high rainfall on the western side of the Southern Alps, the river level can rapidly rise.
