Mount Bold Reservoir
Mount Bold Reservoir is the largest reservoir in South Australia with a maximum capacity of over forty-six thousand megalitres. Costing A$1.1 million, the reservoir took six years to construct on the Onkaparinga River system between 1932 and 1938. The reservoir does not connect directly to the main reticulation system; rather, to maintain levels at Clarendon Weir, water is released only as required. Much of the water from Mount Bold will eventually end up at Happy Valley Reservoir and used to supply parts of the Mount Lofty Ranges and also Adelaide. A major renovation was completed in 1964 when the level of the dam was raised 6.4 metres to increase the reservoir's capacity by approximately 17,000 megalitres. Although originally supplying its own electricity through a small hydro-electricity plant, this was discontinued in 1961. However, Mount Bold is now considered a possible site for a future commercial mini-hydro generator. In early June 2007, the South Australian Government ...

South Australia
South Australia (commonly abbreviated as SA) is a States and territories of Australia, state in the southern central part of Australia. With a total land area of , it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people. It is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in the nation after Western Australia, with more than 77% of South Australians living in the capital Adelaide or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 26,878. South Australia shares borders with all the other mainland states. It is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria (state), Victoria, and to the s ...

Government Of South Australia
The Government of South Australia, also referred to as the South Australian Government or the SA Government, is the executive branch of the state government, state of South Australia. It is modelled on the Westminster system, meaning that the highest ranking members of the executive are drawn from an elected Parliament of South Australia, state parliament. Specifically the party or coalition which holds a majority of the South Australian House of Assembly, House of Assembly (the lower chamber of the South Australian Parliament). History South Australia was established via Letters Patent establishing the Province of South Australia, letters patent by King William IV in February of 1836, pursuant to the South Australia Act 1834, ''South Australian Colonisation Act 1834''. Governance in the colony was organised according to the principles developed by Edward Gibbon Wakefield, Edward Wakefield, where settlement would be conducted by free settlers rather than convicts.

Arch Dams
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have larger ...

Dams Completed In 1938
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Opposition (Australia)
In Australian parliamentary practice, the Opposition or the Official Opposition consists of the second largest party or coalition of parties in the Australian House of Representatives, with its leader being given the title ''Leader of the Opposition''. The Opposition serves the same function as the official opposition in other Commonwealth of Nations monarchies that follow the Westminster conventions and practices. It is seen as the alternative government and the existing administration's main opponent in the Australian Parliament and at a general election. By convention, the Opposition Leader in the federal Parliament comes from the House of Representatives, as does the deputy, although the Government and Opposition may also both have leaders in the Senate. The Opposition is sometimes styled as ''His Majesty's Loyal Opposition'' to show that, although the group may be against the sitting government, it remains loyal to the Crown (the embodiment of the Australian state), and thus t ...

Mini-hydro
Small hydro is the generation of hydroelectric power on a smaller scale as compared to traditional large-scale hydro. Exact definitions vary by country, but small hydro power (SHP) projects are typically less than 50 megawatts (MW) and can be further subdivided by scale into "mini" (<500kW), "" (<100 kW), and "" (<10 kW). Maximum power generation capacity is the primary factor of SHP classification. Factors like dam height, height, reservoir area, outlet structures and operating procedures are not standardized under this metric. SHP projects have grown rapidly in the past two decades. Quicker permitting processes can make them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Hydro-electricity
Hydroelectricity, or hydroelectric power, is 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 sources combined and also more than nuclear power. Hydropower can provide large amounts of 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.
