Cotter River System
The Cotter River System (CRS) is located in the Australian Capital Territory and was constructed in 1912. A feature of the Namadgi National Park, the Cotter River System is one of two main sources for the Australian Capital Territory's water supply, the other being the Queanbeyan River located north of the Australian Capital Territory in New South Wales. Nevertheless, the Cotter River System is a larger catchment area and due to recent drought conditions the Queanbeyan River has been seen as obsolete in comparison. Comprising three primary dams, the Cotter River System has been a reliable water source despite low precipitation and high temperatures experienced in the Australian Capital Territory in the past decade.

Australian Capital Territory
The Australian Capital Territory (commonly abbreviated as ACT), known as the Federal Capital Territory (FCT) until 1938, is a landlocked federal territory of Australia containing the national capital Canberra and some surrounding townships. It is located in southeastern Australian mainland as an enclave completely within the state of New South Wales. Founded after Federation as the seat of government for the new nation, the territory hosts the headquarters of all important institutions of the Australian Government. On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the ''Seat of Government Act 1908'' was passed in 1908 which specified a capital in the Yass-Canberra region. The territory was transferred to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namadgi National Park
Namadgi National Park is a protected area in the south-west of the Australian Capital Territory (ACT), bordering Kosciuszko National Park in New South Wales. It lies approximately southwest of Canberra, and occupies approximately 46 percent of the ACT's land area. Created in 1984, the park is on the Australian National Heritage List. It suffered badly in the 2019–20 Australian bushfire season, with around 80% of its vegetation burnt. History Aboriginal history and custodianship ''Namadgi'' is a local Aboriginal name for the mountains situated to the south-west of Canberra. Aboriginal presence in the area has been dated to at least 21,000 years. With radiocarbon dates of cultural deposits dating back to 9000–6000 years. There are numerous Aboriginal sites in the national park including rock paintings at Yankee Hat, dating from at least 800 years ago. The area is one of cultural significance to the Aboriginal Australian peoples of the Australian Alps region, in particula ...

Water Supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural). It usually includes issues surrounding policy and regulation, service provision and standardization. The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). Almost all service providers in the world charge tariffs to recover part of their costs. Water supply is a separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queanbeyan River
The Queanbeyan River, a perennial stream that is part of the Molonglo catchment within the Murray–Darling basin, is located in the Monaro and Capital Country regions of New South Wales and the Australian Capital Territory, in Australia. The river is in length with a catchment area of . The Queanbeyan River and the Cotter River meet the potable water supply needs of the Canberra and Queanbeyan region and whose water quality is specifically protected under Federal legislation. It is believed that the local Aboriginal Ngarigo people used a word that sounded like ''queanbeyan'' to describe the river, said to mean "clearwater". River course The headwaters of the Queanbeyan River rise east-southeast of Queanbeyan and about northeast of the township of Bredbo, near the village of Jerangle. Fourteen tributaries upstream of the Googong Dam contribute to the river flow including the Burra, Urialla, Tinderry, Ballinafad, Groggy, Woolpack, Sherlock, Lyons, Towneys and Mile Creeks. Th ...

Dams
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 earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precipitation (meteorology)
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers. Moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotter River
The Cotter River, a perennial river of the Murrumbidgee catchment within the Murray–Darling basin, is located in the Australian Capital Territory, Australia. The Cotter River, together with the Queanbeyan River, is one of two rivers that provides potable water to the Canberra and Queanbeyan region. Course The river rises on the eastern slopes of the Brindabella Ranges in the south-west of the Australian Capital Territory (ACT), within Namadgi National Park, and flows generally north, joined by six minor tributaries, including Paddys River, before reaching its confluence with the Murrumbidgee River, near Casuarina Sands, west of the suburb of Weston Creek. The river descends over its course. History The traditional custodians of the land surrounding the Cotter River are the Aboriginal people of the Ngunnawal clan. The river was named in honour of Garrett Cotter, an Irish-born convict who was transported to Australia for "the term of his natural life". Cotter was banishe ...
