Boulder Lake Hut on the shores of Boulder Lake

Boulder Lake (elevation 985 metres or 3,232 feet) is a lake in the Tasman District of New Zealand located within Kahurangi National Park. In the late 1890s and early 1900s, water from the lake was used for gold mining purposes for which the lake level was raised by a low dam. British investors lost much money with the venture and large scale mining stopped in 1905 when a flood took out part of the flume. The dam was blown up in the 1930s by a farmer disgruntled with depression-era gold miners stealing his sheep. Boulder Lake is today a tramping destination, with the Department of Conservation maintaining both a hut at the lake and a track to the lake.

Description

Several creeks, many of them coming from the Colosseum Ridge, flow into the lake. The outflow is the Boulder River. [1]

Mining history

The Collingwood Goldfields Company built a dam in 1899 [2] and although it was only 3 metres (9.8 ft) high, it doubled the size of the lake. The lake water was used for mining gold through sluicing and 8 kilometres (5.0 mi) of flume was built. As the site was above the tree line, the company purchased a large area within the upper Aorere Valley, installed a sawmill, and built a tramway of 6.4 kilometres (4 mi) into the hills. The timber was punted across the Aorere River before the tram transported it towards Boulder Lake to build the flume. [3] Sluicing started on 28 August 1899, [4] but the yield of gold was much less than anticipated. [5]

The Collingwood Goldfields Company, headquartered in London, went into liquidation during 1900 and was refloated in the same year with new capital. [6] Also in 1900, the sawmill in the Aorere Valley was sold to Auckland. [7] The company remained in a difficult financial position and in December 1901, it sold its assets at auction; the purchaser was Charles Fell, who had been acting as the company's solicitor. [8] When a flood destroyed part of the fluming in 1905, operations ceased. [5]

The dam was blown up in the 1930s by a farmer disgruntled with desperate miners stealing his sheep during the Great Depression. [5]

Current use

The Golden Bay Alpine and Tramping Club formed in 1961 and in 1962, Boulder Lake Hut was built by its members. A second hut was built by the Department of Conservation (DOC) during the 1994/95 summer and the older hut has since served as a woodshed. [9] [10]

DOC maintains a tramping track from the road end near Bainham to Boulder Lake Hut. The walk to the hut takes between eight and ten hours (one way) and requires moderate fitness and moderate tramping experience. From a vantage point near the remains of the lake dam, a 65 metres (213 ft) waterfall can be viewed; this is the beginning of the Boulder River. [11]

Gold rush New gold discovery triggering an onrush of miners seeking their fortune

A gold rush or gold fever is a discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, New Zealand, Brazil, South Africa, the United States, and Canada while smaller gold rushes took place elsewhere.

Hydraulic mining Mining technique using high-pressure water jets to carve away minerals

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.

Tasman District Government district of New Zealand

Tasman District is a local government district in the northwest of the South Island of New Zealand. It borders the Canterbury Region, West Coast Region, Marlborough Region and Nelson City. It is administered by the Tasman District Council, a unitary authority, which sits at Richmond, with community boards serving outlying communities in Motueka and Golden Bay / Mohua. The city of Nelson has its own unitary authority separate from Tasman District, and together they comprise a single region in some contexts, but not for local government functions or resource management (planning) functions.

Kawarau River River in the South Island of New Zealand

The Kawarau River is a river in the South Island of New Zealand. It drains Lake Wakatipu in northwestern Otago via the lake's Frankton Arm. The river flows generally eastwards for about 60 kilometres (37 mi) and passes through the steep Kawarau Gorge until it joins Lake Dunstan near Cromwell. Before the construction of the Clyde High Dam, the Kawerau joined the Clutha River / Mata-Au in a spectacular confluence at Cromwell. The Shotover River enters the Kawerau from the north; the Nevis River enters it from the south. With many rapids and strong currents, the river can be dangerous and has claimed many lives. It is popular for bungy jumping and kayaking.

Heaphy Track

The Heaphy Track is a popular tramping track in the north west of the South Island of New Zealand. It is located within the Kahurangi National Park and classified as one of New Zealand's nine Great Walks by the Department of Conservation. Named after Charles Heaphy, the track is 78.4 kilometres (48.7 mi) long and is usually walked in four or five days. The track runs from Kohaihai, north of Karamea on the northern west coast of the South Island to the upper valley of the Aorere River, inland from Golden Bay.

Otago Gold Rush Gold Rush that occurred during the 1860s

The Otago Gold Rush was a gold rush that occurred during the 1860s in Central Otago, New Zealand. This was the country's biggest gold strike, and led to a rapid influx of foreign miners to the area - many of them veterans of other hunts for the precious metal in California and Victoria, Australia.

Osceola Ditch United States historic place

The Osceola Ditch, also known as the East Ditch, was built in 1889–1890 to convey water from Lehman Creek, Nevada to a hydraulic mine operation at Osceola. Extending for 18 mi (29 km), the ditch includes a 600 ft (180 m) tunnel as well as wooden flumes. The project also includes a rock dam and headgate on Stella Lake. The ditch's terminus at Osceola, Nevada became disused during the early 1900s and was destroyed entirely by a fire in the 1940s. Much of the East Ditch is included within Great Basin National Park.

Confederate Gulch and Diamond City

Confederate Gulch is a steeply incised gulch or valley on the west-facing slopes of the Big Belt Mountains in the U.S. state of Montana. Its small stream drains westward into Canyon Ferry Lake, on the upper Missouri River near present-day Townsend, Montana. In 1864, Confederate soldiers on parole during the American Civil War made a minor gold discovery in the gulch, but the discovery of the sensationally rich Montana Bar the following year—one of the richest placer strikes per acre ever made—led to other rich gold strikes up and down the gulch, and touched off a frantic boom period of placer gold mining in the area that extended through 1869. From 1866 to 1869, the gulch equaled or outstripped all other mining camps in the Montana Territory in gold production, producing an estimated $19–30 million worth of gold. For a time, Confederate Gulch was the largest community in Montana. In 1866, Montana had a total population of 28,000, and of these, about 10,000 (35%) were working in Confederate Gulch.

Australian gold rushes Mass movement of Australian workers to places rumored to have gold (1851–1910s)

During the Australian gold rushes, starting in 1851, significant numbers of workers moved from elsewhere in Australia and overseas to where gold had been discovered. Gold had been found several times before, but the colonial government of New South Wales had suppressed the news out of the fear that it would reduce the workforce and so destabilise the economy.
