  Lake Pedder - Wikipedia, the free encyclopedia
Lake Pedder is the name of a former natural lake, located in the southwest of Tasmania, Australia, and the name used to refer to the larger man-made reservoir formed when the original lake was flooded by damming.
These dams were completed in 1972 as part of a push by the Government to increase industry in the State by providing cheap renewable energy in the 1970s.
Scotts Peak is a 43 m high rockfill dam with a bitumen upstream face on the upper reaches of the Huon River near Scotts Peak.

Rock-fill dams are embankments of loose rock with either a watertight upstream face of concrete slabs or timber or a watertight core.
Earth dams, also called earthen and earth-fill dams, are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concrete or clay core or upstream face, or sometimes with a hydraulic fill to produce a watertight core.
A type of temporary earth dam occasionally used in high latitudes is the frozen-core dam, in which a coolant is circulated through pipes inside the dam to maintain a watertight region of permafrost within it.

 Lake Argyle - Wikipedia, the free encyclopedia
Lake Argyle (16°19′S 128°43′E) is Australia's largest artificial lake (by area), part of the Ord River Scheme, near the East Kimberley (Western Australia) town of Kununurra, located on the Kimberley Plateau.
Lake Argyle's usual storage volume is 5,797,000 megalitres, making it the second largest reservoir in Australia (the combined Lake Gordon/Lake Pedder in Tasmania is the largest.) At maximum flood level, the lake would hold 35 million megalitres of water and cover a surface area of 2072 square kilometres.
The lake is now home to 26 species of native fish and a population of freshwater crocodiles currently estimated at some 25,000.

 Dam - Encyclopedia, History, Geography and Biography   (Site not responding. Last check: 2007-10-04)
A diversionary dam is a structure designed to divert all or a portion of the flow of a river from its natural course.
Timber dams were widely used in the early part of the industrial revolution and in frontier areas due to ease and speed of construction.
The locations where timber dams are most economical to build are those where timber is plentiful, cement is costly or difficult to transport, and either a low head diversion dam is required or longevity is not an issue.

 Franklin Dam - Wikipedia, the free encyclopedia
The Franklin Dam or Gordon-below-Franklin Dam project was a proposed dam on the Gordon River in Tasmania, Australia, for the purposes of hydroelectricity.
Over the five years between the announcement of the dam proposal in 1978 and the axing of the plans in 1983, there was vigorous debate between the pro-and-anti-dam lobbies, with large protests from both sides.
However, the protest movement which had gathered to fight the construction of the Lake Pedder Dam earlier in the 1970s began to reassemble in response to the announcement.

 Britain.tv Wikipedia - Dam
Dams can be formed by human agency, natural causes, or by the intervention of wildlife such as beavers.
Dams which are formed by human agency are typically classified according to structure, intended purpose or height.
However, in order to prevent tensile stress at the upstream face and excessive compressive stress at the downstream face, the dam cross section is usually designed so that the resultant falls within the middle at all elevations of the cross section (the core).

 Dam
A diversionary dam is a structure designed to divert a portion river.
Rarely built in modern times by humans due to relatively short lifespan and limited height to which they can be built, timber dams must be kept constantly wet in order to maintain their water retention properties and limit deterioration by rot, similar to a barrel.
A Steel dam is a type of dam briefly experimented with in around the turn of the 19th-20th century which uses steel plating (at an angle) and load bearing beams as the structure.

 Lake Pedder Information
Lake Pedder is a lake, enlarged by flooding for a hydro electric dam, located in the southwest of Tasmania, Australia.
These dams were completed in 1972 as part of a push by the Government to increase industry in the State by providing cheap renewable energy in the 1970s.
Concerns over the construction of the dam revolved around the loss of the distinctive pink quartzite beach of the original lake, and an increased understanding of the unique nature of the wilderness quality to the south west of Tasmania.

 Green Left - Lake Pedder to be restored?
Famous for its breathtaking beauty, Lake Pedder was regarded as the jewel of the south-west wilderness.
The IUCN motion noted that the “restoration of Lake Pedder would be a symbol to the world of a determination to redress some of the environmental mistakes of the past”.
Other studies have found that the soils around the lake are still held together by dead vegetation, indicating that it may not yet be too late to restore the vegetation cover of the surrounding area.

 MILESAGO - Features - Lake Pedder
Like the damming of the Colorado with the construction of the famous Hoover Dam in Nevada, USA, the Snowy scheme was hailed as an engineering triumph, a technological realisation of the age-old dream of taming the awesome power of nature and turning it to the service of humanity.
The lake was famous for its exquisite beauty and the pink quartzite sand of its beach, and it was the centrepiece of Lake Pedder National Park, established in 1955.
So far no new dams have been built, but what was constructed and came at an enormous environmental price, and the ultimate irony is that Lake Pedder would have been far more valuable to Tasmania if it had been left intact for tourism, than as a source of power.

 Lake Pedder
In 1967 the Save Lake Pedder National Park Committee was formed, but was unable to prevent the flooding of Lake Pedder in the face of HEC and Tasmanian government resolve, and the federal government's indifference to environmental matters.
Lake Pedder stands as a symbol of Australia's struggle between environmentalists and large development projects.
In October the federal parliament received the Rose Report, which stated that the federal government had the power to stop the construction of the dam under it's obligation to the provisions of the UNESCO Convention for the Protection of the World Cultural and Natural Heritage (1972), to which Australia was a signatory in 1974.

"Lake Pedder provides about 40 percent of the average flow to Tasmania's biggest power station, the Gordon Power Station, which in turn provides about 13 percent of the State's total power supply.
The lake is a source of stored energy that Tasmania cannot afford to lose.
Without the storage in Lake Pedder the situation would be worse and the State would be that much closer to having to run Bell Bay Power Station at vast cost, with the possibility of tariff increases to meet that extra cost.

 Green Left - Issues: Restoration of Pedder is economically feasible
HOBART -- The “Pedder 2000” campaign -- to restore Tasmania's Lake Pedder to its original condition -- has attracted considerable attention since it was launched on April 18 by David Bellamy, Bob Brown and the David Suzuki Foundation.
A restored Pedder would bring “hope to a new generation” and be “a catalyst for environmental repair around the globe”.
The Pedder 2000 project is being promoted as symbolising a new relationship: “If we are going to all this trouble to restore what was once wilderness, then from now on we must protect the rest and our whole environment, so that we won't ever have to do this again”.
