Lake Rotorangi
Lake Rotorangi is the largest lake in the New Zealand region of Taranaki. The reservoir was created in 1984 by the damming of the Pātea River. History Lake Rotorangi was formed in 1984 as a reservoir for hydroelectric power. The lake was formed by building an 80-metre high earth wall dam near the end of Ball Road in South Taranaki District. The dam created then filled the Patea River valley for a distance of about 46 kilometres to make the longest reservoir of its type in 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 count .... The Pātea Dam is owned by Manawa Energy (formerly Trust Power) and rated at 33 MW output (115 GWh per annum). Pātea is operated as a peaking station. With around one week's storage capacity, the station generates electricity over periods when el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taranaki Region
Taranaki is a region in the west of New Zealand's North Island. It is named after its main geographical feature, the stratovolcano of Mount Taranaki, also known as Mount Egmont. The main centre is the city of New Plymouth. The New Plymouth District is home to more than 65 per cent of the population of Taranaki. New Plymouth is in North Taranaki along with Inglewood and Waitara. South Taranaki towns include Hāwera, Stratford, Eltham, and Ōpunake. Since 2005, Taranaki has used the promotional brand "Like no other". Geography Taranaki is on the west coast of the North Island, surrounding the volcanic peak of Mount Taranaki. The region covers an area of 7258 km2. Its large bays north-west and south-west of Cape Egmont are North Taranaki Bight and South Taranaki Bight. Mount Taranaki is the second highest mountain in the North Island, and the dominant geographical feature of the region. A Māori legend says that Mount Taranaki previously lived with the Tongariro, Ngaur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Pātea River
The Pātea River is in Taranaki in the North Island of New Zealand. It runs for 105 kilometres from the eastern slopes of Mount Taranaki, passing east through Stratford before swinging south and reaching the South Taranaki Bight near the town of Patea. The river was the original portal to South Taranaki for both Māori and Europeans. In the early days of colonial New Zealand, the Pātea River defined the boundary between New Ulster Province and New Munster Province (from 1841 to 1853—refer to Provinces of New Zealand). Many enjoy canoeing in the Pātea River—it is the only navigable river in South Taranaki. Lake Rotorangi on the river is the longest man-made lake in New Zealand (46 km), formed when the Egmont Electric Power Board built the Patea Dam in 1979–84. The interesting southern access drive is via Ball Road through Alton and Hurleyville Hurleyville is a community in south Taranaki, in the western North Island of New Zealand. It is located 18 ...

Lake
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 la ... [...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 ...
