The Grebe River is a river in Fiordland, New Zealand. It arises north-west of Lake Monowai in an area once part of the lake but cut off by an enormous landslide about 13,000 years ago. [1] The river now flows north, between the Townley Mountains to the west, and the Hunter Mountains to the east, and into Lake Manapouri's South Arm. Its major tributaries are Jaquiery Stream, Florence Stream, Emerald Stream, and Percy Stream, all from the west. [2] [3]

Borland Road runs along much of the Grebe Valley to Lake Manapouri. It was built in 1963 to support a transmission line between the lake and Tiwai Point aluminium smelter. [4] A tramping track runs from the northern end of Lake Monowai to the head of the Grebe and up to the road. The Department of Conservation maintains several huts for trampers in the area. [5]

Whitewater kayaking/canoeing is possible on the last three km of the Grebe, from Percy Valley to Lake Manapouri. [6]

<span class="mw-page-title-main">Fiordland</span> Geographical region of New Zealand

Fiordland is a geographical region of New Zealand in the south-western corner of the South Island, comprising the westernmost third of Southland. Most of Fiordland is dominated by the steep sides of the snow-capped Southern Alps, deep lakes, and its steep, glacier-carved and now ocean-flooded western valleys. The name "Fiordland" comes from a variant spelling of the Scandinavian word for this type of steep valley, "fjord". The area of Fiordland is dominated by, and very roughly coterminous with, Fiordland National Park, New Zealand's largest National Park.

<span class="mw-page-title-main">Dobson River (New Zealand)</span> River in the South Island of New Zealand

The Dobson River is a river in the South Island of New Zealand. It flows south between the Neumann and Ohau ranges for 45 kilometres (28 mi) from its source to the east of Mount Hopkins, in the Southern Alps, before joining with the Hopkins River, close to the latter's entry into the northern end of Lake Ōhau in the Mackenzie Country. The river flows over wide shingle beds, and has no rapids of interest to whitewater enthusiasts. It was named by Julius von Haast in the 1860s for his father-in-law, Edward Dobson, who was the Canterbury Provincial Engineer. The Māori name, also given as Otao in some works, means "driftwood," and has also been applied to the Hopkins River into which the Dobson/Ōtaao flows.

Green Lake is a lake in Hunter Mountains in the Southland Region of New Zealand located to the north of Lake Monowai. The lake has no surface outlets but probably feeds several streams draining to lake Monowai via springs. The lake is a basin in the debris of the Green Lake Landslide, which is the largest known above-sea-level landslide on earth. Steep escarpments on the north and east sides of the lake form the head scarp of the landslide, which has an estimated volume of 27 cubic kilometres (6.5 cu mi).
