Lake Mahinerangi
Lake Mahinerangi is a lake formed when a dam was built on the Waipori River for hydroelectric generation. The lake is to the west of Dunedin in New Zealand's South Island. Construction of the dam started in 1903 and since 1907, power has been produced. Naming The lake was named for Dorothy Kathleen Mahinerangi Burnett. She was the daughter of William Burnett, who was mayor of Dunedin in 1911 and 1912. The lake has a maximum length of , and lies on the western side of Maungatua, above and to the west of the Berwick Forest. It is surrounded by farmland, tussock grasslands, and plantation forest. Hydro-electric development The tributaries of the Waipori River are in the Lammerlaw Range. The river descends gradually until the Waipori Gorge, where it suddenly drops in approximately . This makes the gorge an ideal site for a hydro-electric scheme. The first proposals to develop the river for hydro-electric generation were prepared in 1900, for powering gold mining dredges.

Clutha District
Clutha District is a local government district of southern New Zealand, with its headquarters in the Otago town of Balclutha. The Clutha District has a land area of and an estimated population of as of . Clutha District occupies the majority of the geographical area known as South Otago. Geography The geography of the Clutha District is dominated by the valley of the Clutha River, which flows southeast from the lakes of Central Otago, bisecting the Clutha District and reaching the Pacific Ocean via two river mouths, one of which is not far from Kaitangata, the other is closer to Kaka Point. The two branches of the river (the Matau and the Kouau) form the island of Inch Clutha. To the south of this is the rough bush country of the Catlins, with its forests and rugged coastline. To the north of the Clutha valley is mainly rolling hill country, with the plain of the Tokomairaro River to the northeast, along with Lake Waihola and Lake Waipori, which are part of the catchment of ...

Berwick Forest, New Zealand
Berwick Forest is a large ''Pinus radiata'' (Pine) plantation at Berwick in New Zealand, around 40 km west of Dunedin. The forest lies close to the banks of the Waipori River immediately below and around the western end of Lake Mahinerangi, and consists of three blocks - the main block, Maungatua, and Waitahuna, with a total area of 13,141 hectares. The land is owned by Otago Land Company, a sub company of Boston-based investment company GMO LLC, the trees by Wenita Forest Products, which has shareholders Sinotrans (62%), the Chinese shipping company, and GMO.

Lakes Of Otago
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahinerangi Wind Farm
The Mahinerangi Wind Farm is a wind farm on the north side of Lake Mahinerangi, around 50 km west of Dunedin, in Otago, New Zealand. Stage one of the wind farm, generating 36 MW, was commissioned in March 2011, and an additional 160 MW is consented to be commissioned in further stages. The wind farm is owned and operated by Mercury NZ Ltd. It was the second major wind farm to be built in the South Island. History Resource consent was granted in 2007 and later confirmed after an appeal to the Environment Court. Construction of stage 1 of the wind farm, consisting of twelve turbines, began in September 2010. Vestas V90-3MW turbines were chosen for the wind farm, having previously been used for stage 3 of Tararua Wind Farm in 2007. Turbines were shipped to Port Chalmers, and trucked through Dunedin to their final site. The wind farm generated its first electricity on 21 February 2011, with the first two turbines being commissioned. All twelve stage one turbines were ...

In 1966 the New Zealand Government published ''An Encyclopaedia of New Zealand'', its first official encyclopedia, in three volumes. Although now superseded by ''Te Ara'', its historical importance led to its inclusion as a separate digital reso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The developme ...

Halfway Bush
Halfway Bush is a suburb of the New Zealand city of Dunedin. It is located to the northwest of the city centre, close to the point at which Taieri Road becomes the winding rural Three Mile Hill Road. It was this road which gave the suburb its name, as this locality was halfway between the Taieri Plains and central Dunedin in the early days of European settlement, when Three Mile Hill was the main route from Dunedin to the Otago hinterland. This route was superseded by the route through the Caversham Valley in the 1860s. Halfway Bush is the most inland of the suburbs which comprise Dunedin's main urban area, and is at an altitude of . For these reasons, it often receives harsher winter weather than much of the rest of the city. Whereas central Dunedin may only receive passing snow showers on average one or two days per year, snow will often settle on the streets of Halfway Bush for several days per year. The suburb is connected to central Dunedin by Taieri Road, which runs thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lammerlaw Range
The Lammerlaw Range is in the Otago region of New Zealand. It is an important watershed, and the source of many of the tributaries in the Taieri and lower Clutha River systems. The origins of the placename are Scottish. Windfarms have been sited in the area. The area includes distinctive geology including ribbon fens and peat habitats. The Lammerlaw and Lammermoor Ranges also include tussock grasslands. Parts of the ranges are in Te Papanui Conservation Park. The endangered Eldon's galaxias (''Galaxias eldoni'') is found in the range.

Maungatua
Maungatua, known also as Maukaatua is a prominent ridge in the Taieri Plains in Otago, New Zealand. It rises 895 metres above the floodplain of the Taieri River, directly to the west of Dunedin's airport at Momona. It can be clearly seen from much of Dunedin's urban area, 35 kilometres to the east, and from as far south as the outskirts of Balclutha, 65 kilometres to the southwest. Lake Mahinerangi is located on the western side of Maungatua. The name Maungatua comes from the Māori words ''Maunga-atua'', meaning "Hill of the spirits". Ecology of Maungatua Maungatua features a diverse range of plant species. The summit features tussock grassland and cushion bogs, whilst the sub-alpine zone includes shrubland and tussock grasslands. Carnivorous insect eating plants called sundews are found within swamps at the summit. Silver beech dominates the montane slopes, particularly on the southern face. This transitions to lowland podocarp forest which extends into the Waipori Gorge. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otago
Otago (, ; mi, Ōtākou ) is a region of New Zealand located in the southern half of the South Island administered by the Otago Regional Council. It has an area of approximately , making it the country's second largest local government region. Its population was The name "Otago" is the local southern Māori dialect pronunciation of "Ōtākou", the name of the Māori village near the entrance to Otago Harbour. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay which is common in the area around Dunedin. "Otago" is also the old name of the European settlement on the harbour, established by the Weller Brothers in 1831, which lies close to Otakou. The upper harbour later became the focus of the Otago Association, an offshoot of the Free Church of Scotland, notable for its adoption of the principle that ordinary people, not the landowner, should choose the ministe ...
