The Buller River (Template:Langx) is a river in the South Island of New Zealand.<ref>Encyclopedia of New Zealand (1966)</ref> The Buller has the highest flow of any river in the country during floods,<ref name=":112">{{#invoke:citation/CS1|citation
|CitationClass=web

|CitationClass=web
}}</ref> A saddle at Template:Convert separates the Buller from the Motupiko River and that is divided from the Wairau River by a Template:Convert saddle, both aligned along the Alpine Fault, as is the top of the Buller valley.<ref name=":172">{{#invoke:citation/CS1|citation

Within the Buller Gorge and downstream from the Deepdale River joining, the Buller crosses from Tasman District into Buller District. The Paparoa Range separates the Buller River from the Grey River. A number of flora and fauna are found in the Buller catchment, many of these extending onto the slopes of the Paparoa Range.
The Buller River upstream from Murchison along with the Mangles River are popular for whitewater kayaking and recreational fishing,<ref>Marion Hobbs. 2001</ref> though the whole river can be kayaked; it is the only major river in the country with no hydro lakes,<ref name=":1">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> though a seismic survey for hydro power was done in 1973.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> For experienced canoeists the Ariki Falls section, between Murchison and Newton Flat, is also popular and novices can use it by carrying kayaks around the rapids, except when the river is very low and the rapids become unnavigable.<ref name=":1" /> The river is suitable for contact recreation approximately 95% of the time, though Tasman Council recognises it needs to be better because of the popularity of whitewater kayaking below Gowan Bridge.<ref>{{#invoke:citation/CS1|citation

This river has an annual mean flow of Template:Convert, is estimated to have reached Template:Convert in the 1926 flood<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

Excavations at the mouth of the river, across from Westport, uncovered 77 stone adzes, 2,693 stone flakes (argillite, chert, obsidian and silcrete from manufacture of stone tools), minnow lures, moa bone, sites of huts, ovens, middens and urupā, with one shell carbon dated to between 1219 and 1316. Early trading is indicated by argillite from Ohana, at the south end of D'Urville Island, chert from upper North island and obsidian from Mayor Island / Tūhua. In 2004 the site was described as one of the largest and best preserved large Archaic sites in the country. More investigation may reveal whether it was occupied for more than a few years.<ref>{{#invoke:citation/CS1|citation

Subsequent pre-colonial history is obscure. The Waitangi Tribunal concluded that, "very little is known about the history of Ngāti Apa's occupation of the region . . . invasion by northern tribes in the early nineteenth century made it difficult to pass on any substantial record of the traditional history of this area" and it was "probably an area of migratory resource use rather than permanent occupation".<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> One migratory resource was Ngāi Tahu's pounamu trade, which had a greenstone trail through the valley,<ref>{{#invoke:citation/CS1|citation

European settlement
Europeans first discovered Lake Rotoiti in 1842.<ref name=":12">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> The first written record of the river mouth was in 1845, when a sealing captain, Joseph Thoms, was reported as finding, "a large river, a mile wide. It has a bar at the entrance, on which he took soundings, and found sixteen feet at high water. The river appeared to be navigable for a considerable distance. Mr. Thoms anchored his vessel in five fathoms, and pulled up four or five miles in his boat. He describes the valley through which the river runs to be twenty miles wide, finely wooded, with some open land."<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

In 1846 Brunner was the first European to follow the full length of the Buller, together with his guide, E Kehu, of Ngāti Tūmatakōkiri, who already knew the area well<ref name=":12" /> (Ekehu had been taken prisoner by Ngāi Tahu while living near the Grey River).<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> That expedition lasted almost 560 days.<ref name=":15">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> The journey was so difficult that they left Lake Rotoiti on 31 December 1846, but only reached the mouth of the river on 4 June 1847.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> They returned up the Buller, leaving Inangahua on 23 March 1848 and reached Lake Rotoiti again on 12 June 1848.<ref name=":15" />
Surveyor John Rochfort discovered gold and coal in the Buller valley in 1859.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> Despite this indication of the land's value, the 1860 Arahura Deed sold most of the West Coast to the government for £300 (about 1d per 100 acres), covering a total of Template:Convert, which included virtually all of the Buller valley south from the Gowan River.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

A West Coast gold rush, coal mines and timber sawmills resulted in a rapid population increase in the 1860s. By 1867 there were 6,087 miners in Nelson Province and 10,466 people (and 1,612 tents, indicating the temporary nature of their stay) in Westland North, which also included the Grey valley. About 1,500 were in Westport in 1867, which was then the 3rd largest port for exporting gold, after Hokitika and Dunedin.<ref>{{#invoke:citation/CS1|citation

Name
William Fox was the New Zealand Company agent (a UK-based company of 1837, with a royal charter supporting colonisation efforts) in Nelson, when he, Thomas Brunner and Charles Heaphy, explored the Buller as far south as Murchison in February 1846.<ref name=":142">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> In a report to Colonel Wakefield, Fox said, "As it will present a considerable feature on the maps of this island, I have called it the Buller, after the member for Liskeard", who was Charles Buller, a UK Member of Parliament and director of the New Zealand Company.<ref name=":22">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref>
The original Māori name for the Buller may have been Kawatiri, although Patrick O'Regan thought that was a misunderstanding of Ka Awatiri.<ref name=":22"/> He translated Awatiri as a rapid river. The first 1846 expedition named the Buller valley around Murchison as the Aglionby valley, after the English MP, Henry Aglionby Aglionby.<ref name=":142"/> In 1911 O'Regan suggested it had dropped out of use because it was hard to pronounce.<ref name=":22" />
River modifications
Organs Island was created, about Template:Convert upstream from Westport,<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

Transport
Until roads were built, goods were carried from Westport to Lyell in fleets of canoes,<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> or, later, horse-drawn boats, carrying up to 7 tons,<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

|CitationClass=web
}}</ref> They could take 11 weeks to make the journey,<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> but the Template:Convert from Lyell could also be covered in 7 hours downstream.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

Roads in the valley evolved. In good weather a footpath was passable along the length of the valley by 1864.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web

Geology
Lake Rotoiti was created by a glacier and glacial moraines occupy a large area between the Buller and Gowan rivers.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> From the lake the Buller flows west through a gorge cut in granitic rocks of the Median Batholith. It then turns southwest to follow the axis of the Longford Syncline to Murchison. Tributary valleys around Murchison commonly follow north-south trending faults and fold axes.<ref name=":172"/>
The Buller's deep gorges have been cut through the mountains as they have been raised by Quaternary faulting and folding. Some 350,000 years ago the river had wide floodplains,<ref name=":18">{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> which remain as flat terraces above the narrow gorge, as at Manuka Flat, now roughly Template:Convert above the river.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> The Murchison Basin was filled between the Late Eocene and Early Miocene by sediments in increasingly shallow waters, indicating that the uplift of the area to the north began in the Early Miocene.<ref>Template:Cite thesis</ref> It was particularly rapid during the late Miocene-Pliocene.<ref>Template:Cite journal</ref>
In the 1929 Murchison earthquake a Template:Convert landslide fell Template:Convert to dam the Buller at Fern Flat, about midway between Murchison and O'Sullivan's Bridge. After two days the dam was washed away. The road between Murchison and Inangahua had 34 landslips, some up to Template:Convert wide.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> The road at White Creek, in the Upper Gorge, was split by a Template:Convert scarp.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> There were also slips in the 1968 Inangahua earthquake, one of which created a Template:Convert high dam in the river, just above Inangahua.<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref>
Above the Lower Gorge, podzol soils lie on sandstones of the Brunner Coal Measures. They are very infertile, acidic and tend to be very poorly drained. At high altitudes, the soils become skeletal and, in many places, unweathered rocks lie on the surface. Brunner Coal Measures are Eocene and were deposited in an estuary.<ref name=":9" /> There were coal mines near the Lower Gorge<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> at Rahui (opened 1942)<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> and Cascade (originally opened to improve mine drainage in 1897).<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref>
Uranium was found in the Lower Gorge in 1955 and searches were made for viable deposits until the 1970s,<ref>{{#invoke:citation/CS1|citation
|CitationClass=web
}}</ref> but all were less than 0.1% U3O8.<ref name=":18" /> In 1972 the mountains on either side of the Gorge were officially named Mounts Cassin<ref>Template:LINZ</ref> and Jacobsen, after the men who discovered the uranium.<ref>Template:LINZ</ref>
In July 2001 the Buller Water Conservation Order came into force, listing the waters of the Buller River and tributaries that are to be retained in their natural state or protected because of the outstanding characteristics, features and values of the waters.<ref>{{#invoke:citation/CS1|citation
