Ōhau River (Canterbury)
The Ōhau River is a river in the Mackenzie Basin of New Zealand's South Island. It is the primary outflow of Lake Ōhau, from which it flows in a roughly eastward direction until reaching the artificial Lake Benmore after a distance of roughly . In 1981, the artificial Lake Ruataniwha was created along the river's length to power a small hydroelectric power station as part of the Waitaki hydro scheme. Prior to the creation of the Waitaki hydro scheme, the river flowed directly into the Waitaki River rather than through a series of lakes. The river forms part of the traditional boundary between Otago and Canterbury regions. Prior to European settlement of the region, the river was a traditional '' mahinga kai'' (food gathering site) for Māori travelling through the Mackenzie Basin, providing valuable food sources such as weka, tuna A tuna (: tunas or tuna) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae ( mackerel) family.

Lake Ruataniwha
Lake Ruataniwha is an artificial lake in the Mackenzie Basin in the South Island of New Zealand. It was formed in 1977–1981 as part of the Waitaki hydroelectric project. It lies on the traditional boundary of the Canterbury and Otago provinces, with the town of Twizel two kilometres to the north. The lake takes its name from the Ruataniwha Station, a large sheep-station in the area, part of which the NZ Electricity Department purchased as the site for the township of Twizel (founded in 1968). Ruataniwha was a Māori chief who drowned when the canoe Arai-te-uru sank near Moeraki in the 12th century CE. Features The lake is approximately 4.5 km in length and covers 3.4 square km. It was formed by the New Zealand Ministry of Works as part of the Upper Waitaki Power Project between 1977 and 1981 in a gorge created by the Ōhau River. The gorge was blocked by the building of the Ruataniwha Dam whose crest carries State Highway 8 between Twizel and Omarama. Lake ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Rivers Of The Canterbury Region
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-finned Eel
The short-finned eel (''Anguilla australis''), also known as the shortfin eel, is one of the 15 species of eel in the family Anguillidae.

There are no markings of note, but the underside is pale, often silvery, and the fins greenish. When full grown, they reach about . The short-finned eel has a typical regeneration time of 15 to 30 years for females and it reaches a maximum size of about a ...

Weka
The weka, also known as the Māori hen or woodhen (''Gallirallus australis'') is a flightless bird species of the rail family. It is endemic to New Zealand. Some authorities consider it as the only extant member of the genus '' Gallirallus''. Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence. The weka are sturdy brown birds about the size of a chicken. As omnivores, they feed mainly on invertebrates and fruit. Weka usually lay eggs between August and January; both sexes help to incubate. Description Weka are large rails. They are predominantly rich brown mottled with black and grey; the brown shade varies from pale to dark depending on subspecies. The male is the larger sex at in length and in weight. Females measure in length and weigh . The reduced wingspan ranges from . The relatively large, reddish-brown beak is about long, stout and tapered, and used as a weapon. The pointed tail is near-constantly being flicked, a si ...

Māori People
Māori () are the Indigenous peoples of Oceania, indigenous Polynesians, Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of Māori migration canoes, canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed Māori culture, a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Early contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi, Treaty of Waitangi/Te Tiriti o Waitangi in 1840, the two cultures coexisted for a generation. Rising ten ...

The provincial headquarters was Nyeri. Central Province was the ancestral home of the Gikuyu people. Climate The climate of Central Province is generally cooler than that of the rest of Kenya, due to the region's higher altitude. Rainfall is fairly reliable, falling in two seasons, one from early March to May (the long rains) and a second during October and November (the short rains). General information Central Province is a key producer of coffee, one of Kenya's key exports. Much of Kenya's dairy industry is also based in this province. The provincial headquarters were in Nyeri.

Mackenzie Basin
The Mackenzie Basin (), popularly and traditionally known as the Mackenzie Country, is an elliptical intermontane river basin, basin located in the Mackenzie District, Mackenzie and Waitaki Districts, near the centre of the South Island of New Zealand. It is the largest such basin in New Zealand. Historically famous mainly for sheep farming, the sparsely populated area is now also a popular tourism destination. The basin was named in the 1850s by and after James Mckenzie (outlaw), James Mckenzie, a shepherd and would-be farmer of Scottish origin. Mckenzie was captured for allegedly stealing sheep; he herded his flocks in what was then an area almost totally empty of any human habitation, though Māori people, Māori previously lived there intermittently. After his capture, the area was soon divided up amongst new sheep pasture stations in 1857. Geography The basin extends approximately north to south, and east to west.
