The Murray River is Australia's longest river, at 2,508 kilometres (1,558 mi) in length. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, and then meanders across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows to the northwest into South Australia. It turns south at Morgan for its final 315 kilometres (196 mi), reaching the ocean at Lake Alexandrina.
Dartmouth Dam is a large rock-fill embankment dam with an uncontrolled chute spillway across the Mitta Mitta, Gibbo, and Dart rivers, the Morass Creek and a number of small tributaries. The dam is located near Mount Bogong in the north-east of the Australian state of Victoria. The dam's purpose includes irrigation, the generation of hydro-electric power, water supply and conservation. The impounded reservoir is called Dartmouth Reservoir, sometimes called Lake Dartmouth. The Dartmouth Power Station, a hydro-electric power station that generates power to the national grid, is located near the dam wall.
The Snowy Mountains scheme or Snowy scheme is a hydroelectricity and irrigation complex in south-east Australia. The Scheme consists of sixteen major dams; seven power stations; one pumping station; and 225 kilometres (140 mi) of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974. The Scheme was completed under the supervision of Chief Engineer, Sir William Hudson. It is the largest engineering project undertaken in Australia.
Hume Dam, formerly the Hume Weir, is a major dam across the Murray River downstream of its junction with the Mitta River in the Riverina region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Hume, formerly the Hume Reservoir. It is a gated concrete gravity dam with four earth embankments and twenty-nine vertical undershot gated concrete overflow spillways.
The Murray–Darling basin is a large geographical area in the interior of southeastern Australia. Its name is derived from its two major rivers, the Murray River and the Darling River. The basin, which drains around one-seventh of the Australian land mass, is one of the most significant agricultural areas in Australia. It spans most of the states of New South Wales and Victoria, the Australian Capital Territory, and parts of the states of Queensland and South Australia. The basin is 3,375 kilometres (2,097 mi) in length, with the Murray River being 2,508 km (1,558 mi) long.
Wyangala Dam is a major gated rock fill with clay core embankment and gravity dam with eight radial gates and a concrete chute spillway across the Lachlan River, located in the south-western slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Wyangala.
Tom Cleave Stott CBE spent 37 years as an independent member of the South Australian House of Assembly, from 1933 to 1970. He served as Speaker of the House from 1962 to 1965 for the Tom Playford LCL government and 1968 to 1970 for the Steele Hall LCL government, both times in exchange for his confidence and supply vote to form minority governments.
Sir Thomas Playford was an Australian politician from the state of South Australia. He served continuously as Premier of South Australia and leader of the Liberal and Country League from 5 November 1938 to 10 March 1965. Though controversial, it was the longest term of any elected government leader in Australian history. His tenure as premier was marked by a period of population and economic growth unmatched by any other Australian state. He was known for his parochial style in pushing South Australia's interests, and was known for his ability to secure a disproportionate share of federal funding for the state as well as his shameless haranguing of federal leaders. His string of election wins was enabled by a system of a malapportionment gerrymander that bore his name, the 'Playmander' − which saw the Labor Party win clear majorities of the statewide two-party vote whilst failing to form government in 1944, 1953, 1962 and 1968.
State elections were held in South Australia on 30 May 1970. All 47 seats in the South Australian House of Assembly were up for election. The incumbent Liberal and Country League led by Premier of South Australia Steele Hall was defeated by the Australian Labor Party led by Leader of the Opposition Don Dunstan.
The 1968South AustralianState election was held in South Australia on 2 March 1968. All 39 seats in the South Australian House of Assembly were up for election; 38 of the 39 contests were won by candidates from Australia's two major political parties. The incumbent Australian Labor Party and the Liberal and Country League both won 19 seats. The sole independent candidate to win a race, Tom Stott of the Ridley electorate, joined with the LCL's 19 seats to form a coalition government that held a 20 to 19 majority, thus defeating the Dunstan Labor government.
Irrigation is a widespread practice required in many areas of Australia, the driest inhabited continent, to supplement low rainfall with water from other sources to assist in growing crops and pasture. Overuse or poor management of irrigation is held responsible by some for environmental problems such as soil salinity and loss of habitat for native flora and fauna.
Cairn Curran reservoir is situated along the Loddon River near the townships of Baringhup, Newstead and Welshmans Reef in Victoria, Australia. Constructed between 1947 and 1956.
The Bear River is a tributary of the Feather River in the Sierra Nevada, winding through four California counties: Yuba, Sutter, Placer, and Nevada. About 73 miles (117 km) long, the river flows generally southwest through the Sierra then west through the Central Valley, draining a narrow, rugged watershed of 295 square miles (760 km2).
The Los Vaqueros Reservoir is located in the northern Diablo Range, within northeastern Contra Costa County, northern California. It was completed by the Contra Costa Water District (CCWD) in 1998 to improve the quality of drinking water for its 550,000 customers in Central and Eastern Contra Costa County, and the reservoir is accessible via Vasco Road, a road which connects Brentwood and Livermore.
As Australia's supply of freshwater is increasingly vulnerable to droughts, possibly as a result of climate change, there is an emphasis on water conservation and various regions have imposed restrictions on the use of water.
The Barmera railway line was the second railway built to develop the Murray Mallee region of South Australia, in 1913. It followed the success of the Pinnaroo railway line in 1906. Both lines branched east from Tailem Bend to the north of the main Melbourne–Adelaide railway. The Brown's Well line was the more northerly, and extended into country which had not been developed much before the railway, partly due to the absence of any viable transport route for produce. The original terminus of the Brown's Well railway was at Meribah, not far from the Victorian border.
The Morgan – Whyalla pipeline was an engineering project undertaken by the South Australian Government in 1940 to bring water from Morgan on the River Murray to the industrial city of Whyalla. A second pipeline, by a divergent route, was laid in the 1960s.
Wonuarra is a locality southeast of Paringa in the east end of the South Australian Riverland region. The locality is east of the Sturt Highway between Paringa and Yamba and extends from the highway to the state border.
Murtho is a locality in South Australia. It is northeast of Renmark and Paringa. It is bounded by the Murray River on its north and west sides and the Victorian border on the east.
The Chowilla floodplain is a floodplain adjacent to the Murray River, upstream of Renmark. The floodplain extends across the state border into New South Wales. It includes the Chowilla Game Reserve.
