Roaring Meg Hydro Scheme
The Roaring Meg hydro scheme refers to two small hydro electricity power stations fed by the Roaring Meg Dam. The scheme is located next to the Roaring Meg Stream in the Kawarau Gorge, near Cromwell, New Zealand. Roaring Meg is owned and operated by Pioneer Energy. History The scheme was built by the Otago Central Power Board starting in 1934 and commissioned 1936, at a cost of 40,000 pounds. At times the lower station has been flooded by the Kawarau River 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 and passes through the steep Kawarau Gorge until it joins L ....Cromwell Handbook 2nd editionhttp://www.cromwell.org.nz/downloads/Handbook2005.pdf Layout The scheme starts with the high Roaring Meg Dam located upstream from the confluence with the Kawarau River.

A roar is a type of animal vocalization that is deep and resonating. Many mammals have evolved to produce roars and other roar-like vocals for purposes such as long-distance communication and intimidation. These include various species of big cats, bears, pinnipeds, bovids, deer, elephants and simians. The anatomical basis for the ability to roar often involves modifications to the larynx and hyoid bone and enlarged internal air spaces for low-frequency vocal resonation. While roaring, animals may stretch out their necks and elevate their heads to increase the space for resonance. Definition The definition of "roar" has varied between species. However Weissengruber et al. (2002) have given a more general description of roars as consisting of both a low pitch and low formant. They have used the roars of lions and red deer as quintessential examples of the sound. Other researchers have mentioned similar "roar-like" vocalizations in which either the pitch or format is still higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawarau Gorge
The Kawarau Gorge is a major river gorge created by the Kawarau River in Central Otago, in the South Island of New Zealand. The towns of Queenstown and Cromwell are linked by through the gorge. The gorge begins some 30 kilometres from Queenstown, close to the wine-growing community of Gibbston and the large rock outcrop known as the Nevis Bluff. It continues for some 25 kilometres before the river emerges into the upper valley of the Clutha River close to the settlement of Ripponvale. The Kawarau gorge's first historical significance was as a travel route to the South Island's West Coast. A natural bridge, "Whatatorere", where the river narrows to 1.2 metres (3.9 ft), was important first to early Māori and then to goldminers as the only place the Clutha and Kawarau rivers could be crossed without boats. Māori were heading for the Cardrona Valley to reach Wānaka, and on to the Haast Pass to seek pounamu. In the 1860s, the gorge was the site of much activity during the Ot ...

Cromwell, New Zealand
Cromwell (Māori: ''Tīrau'') is a town in Central Otago in the Otago region of New Zealand. Geography Cromwell is between (linking to Wānaka, north, and Queenstown via the Kawarau Gorge, west) and State Highway 8 leading to the Lindis Pass, northeast, and Alexandra, 33 km south. The road to Alexandra winds through the Cromwell Gorge. A point near Cromwell lies 119 kilometres from the sea, the farthest from the sea anywhere in New Zealand. A prominent feature surrounding much of the town is the man-made Lake Dunstan. Nearby settlements are at Bannockburn, Lowburn, Tarras, and Ripponvale. Cromwell has a strategic location between the Lindis and the Haast passes, and acts as a hub between the towns of Wānaka, Queenstown and Alexandra. Cromwell is also the home of the Cromwell Chafer Beetle ''(Prodontria lewisi)''. The 45th parallel south runs just north of the township. Cromwell lay at the confluence of the Clutha River and the Kawarau River, which wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Kawarau River
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 and passes through the steep Kawarau Gorge until it joins Lake Dunstan near Cromwell. Before the construction of the Clyde High Dam, the Kawarau joined the Clutha River / Mata-Au in a spectacular confluence at Cromwell. The Shotover River enters the Kawarau 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. A natural bridge, , where the river narrows to , was important first to early Māori and then to goldminers as the only place the Mata-Au and the Kawarau could be crossed without boats. Māori were heading for the Cardrona Valley to reach Wānaka, and on to the Haast Pass to seek pounamu. The miners were seeking gold in the Arrow Goldfields. Now the ...
