Buller River
Length30 km (19 mi)

It runs south for 30 kilometres from its headwaters west of Mount Owen in Kahurangi National Park to its confluence with the Buller River just below the town of Murchison. Halfway along its length, it passes through Lake Matiri.[1] Downstream from Lake Matiri the banks of the river has mixed livestock farming and some small scale forestry.

Recreation

The river is used for whitewater recreation. It has a tight grade III rapid in a narrow cleft of a gorge a short distance upstream of the road end. There are also two bouldery drops that can only be run in high flows when it may reach grade IV. The river is considered to be best run when the Buller River is too high and dangerous.[2]

A tramping track that starts at the road end runs along the western side of the river.

Hydroelectricity

New Zealand Energy Limited have proposed the Matiri Project hydroelectric power scheme on the river.

gollark: I'm on my phone now, so I can't.
gollark: I run a 10x10x10 actively cooled TBU oxide one and 9x9x9 passively cooled LEN-236 oxide one. 55kRF/t (or so) total.
gollark: It'd run hot and inefficiently. Also you want to start with something available directly from thorium or uranium.
gollark: Alternately, the one you have the most of.
gollark: You want the one that runs best for a given reactor.
