The federation of Australia was the process by which the six separate British self-governing colonies of New South Wales, Queensland, South It was created in 1963 after the Molonglo River, which ran between the city centre and Parliamentary Triangle, was dammed. The Molonglo River rises on the western side of the Great Dividing Range of eastern Australia in the state of New South Wales. A central business district ( CBD) is the commercial and often geographic heart of a city The Parliamentary Triangle is the ceremonial precinct of Canberra, containing some of Australia's most significant buildings A dam is a barrier that divides waters. Dams generally serve the primary purpose of retaining water while other structures such as Floodgates, Levees It is named after Walter Burley Griffin, the architect who won the design competition for the city of Canberra. Walter Burley Griffin November 24, 1876 &ndash February 11, 1937) was a US Architect and Landscape architect, An architect is a licensed individual who leads a design team in the Planning and Design of buildings and participates in oversight of Building Construction 
The lake is located in the approximate geographic centre of the city, according to Griffin's original designs. Numerous important institutions, such as the National Gallery of Australia, National Museum of Australia, National Library of Australia and the High Court of Australia lie on its shores, and Parliament House is a short distance away. The National Gallery of Australia is the premier art gallery and museum in Australia, holding over 120000 works of Art. The National Museum of Australia was formally established by the National Museum of Australia Act 1980. The National Library of Australia is the country's largest reference library responsible under the terms of the National Library Act for "maintaining and developing a national The High Court of Australia is the final court of appeal in Australia the highest court in the Australian court hierarchy. Parliament House is the meeting place of the Parliament of Australia. Its surrounds are also quite popular with recreational users, particularly in the warmer months. Though swimming in the lake is uncommon, it is used for a wide variety of other activities, such as rowing, fishing, and sailing. With regard to Watercraft, rowing is the act of propelling a boat using the motion of Oars in the water For the computer security term see Phishing. Fishing is the activity of catching Fish. Sailing is the art of controlling a Sailing vessel. By changing the Rigging, Rudder and dagger or centre board a Sailor manages the force
The lake's flow is regulated by the 33 metre tall Scrivener Dam, which is designed to handle a once in 5000 year flood event. If required in times of drought, water levels can be maintained through the release of water from Googong Dam, located on an upstream tributary of the Molonglo River. A drought is an extended period of months or years when a region notes a deficiency in its water supply The Queanbeyan River joins the Molonglo River at Oaks Estate just within the Australian Capital Territory.
Charles Robert Scrivener (1855–1923) recommended the site for Canberra in 1909, and his detailed survey plans of the area were supplied to the architects who entered the Canberra design competition. Charles Robert Scrivener ( November 2, 1855 - September 26, 1923) was an Australian surveyor, and the person who surveyed Later, Scrivener, as part of a design committee, was responsible for modifying Griffin's winning design.  He recommended changing the shape of the lake from Griffin's very geometric shapes to a much more organic one using a single dam, unlike Griffin's series of weirs. WEIR (1430 AM) is a Radio station broadcasting a News Talk Information format The new design included elements from several of the best design submissions and was widely criticised as being ugly. The new plan for the lake retained Griffin's three formal basins: east, central, and west, though in a more relaxed form.  The plans were varied again in the following years with the return of Griffin, but the design of Lake Burley Griffin remains based largely on the original committee's plan.
The lake contains 33 million m3 of water with a surface area of 6. CM3 redirects here If you were looking for the 3rd game in the Cooking Mama series abbreviated as CM3 see here. Surface area is the measure of how much exposed Area an object has 64 km2 (2. Square Kilometre ( US spelling square kilometer) symbol km2, is a decimal multiple of the SI unit of 56 sq mi). It is 11 kilometres (7 mi) long, 1.

The term above mean sea level ( AMSL) refers to the Elevation (on the ground or Altitude (in the Air) of any object relative to the  Lake Burley Griffin contains six islands, three unnamed small islands and three larger named islands. Of the larger islands, Aspen Island is located in Central Basin while Springbank and Spinnaker Island are located in the West Basin. Aspen Island is an island within Lake Burley Griffin, in the centre of Canberra, Australia's federal Capital city. Springbank Island is an island within Lake Burley Griffin, in the centre of Canberra, Australia. Spinnaker Island is an island within Lake Burley Griffin, in the centre of Canberra, Australia's federal Capital city. Aspen Island is connected to dry land by a footbridge and is the site of the Australian National Carillon. The National Carillon, situated on Aspen Island in central Canberra, Australia is a large Carillon managed and maintained by the National
Construction of Lake Burley Griffin was begun in 1960 and progressed well due to drought having greatly reduced the water flow of the Molonglo River. Critics believed that the lake would act as a breeding ground for mosquitoes. Mosquitoes are insects in the family Culicidae. They have a pair of scaled wings a pair of Halteres, a slender body and long legs Care was taken to excavate the lake to a depth of over two metres both to prevent mosquitoes from breeding and to allow clearance for boat keels. The lake varies in depth from around 2 metres at the eastern end, to 18 metres at the dam wall. The mean depth is 4 metres.
The dam used to create Lake Burley Griffin was named Scrivener Dam after Charles Robert Scrivener. Charles Robert Scrivener ( November 2, 1855 - September 26, 1923) was an Australian surveyor, and the person who surveyed The dam is 33 metres high and 319 metres long with a five bay spillway controlled by 30. A spillway is a structure used to provide for the controlled release of flows from a Dam or Levee into a downstream area typically being the river that was dammed 5 metre wide, hydraulically operated fish-belly flap gates. Hydraulic machinery are machines and tools which use Fluid power to do work Floodgates are adjustable gates used to control water flow in reservoir, River, Stream, or Levee systems The fish-belly gates allow for a precise control of water level, reducing the dead area on the banks between high and low water levels. The five gates have only been opened simultaneously once in the dam's history, during flooding in 1976. The dam is designed to handle a once in 5000 year flood event. The dam contains 55,000 cubic metres of concrete with a maximum wall thickness of 19. CM3 redirects here If you were looking for the 3rd game in the Cooking Mama series abbreviated as CM3 see here. Concrete is a construction material composed of Cement (commonly Portland cement) as well as other cementitious materials such as Fly ash and Slag 7 metres. A roadway atop the dam wall provides a third road crossing for the lake.
The drought that had made construction easy meant that when the valves were closed on 20 September 1963 the lake was very slow to fill. Events 451 - The Battle of Chalons takes place in North Eastern France. Year 1963 ( MCMLXIII) was a Common year starting on Tuesday (link will display full calendar of the Gregorian calendar. After seven months there was still only a trickle of water and some mosquito-infested pools. Luckily the drought broke and the lake was filled after only several days of heavy rain. 
On October 17, 1964 Robert Menzies commemorated the filling of the lake and the completion of stage one with an opening ceremony. Events 539 BC - King Cyrus The Great of Persia marches into the city of Babylon, releasing the Jews from almost Year 1964 ( MCMLXIV) was a Leap year starting on Wednesday (link will display full calendar of the 1964 Gregorian calendar.

Sir Gordon Freeth KBE ( 6 August 1914 – 27 September 1994) was an Australian politician Menzies insisted that the lake should be named after Walter Burley Griffin—Canberra's designer responsible for the concept of the lake—who had no existing monument in Canberra. (Griffin usually referred to himself as Walter Griffin, but the form "Walter Burley Griffin" has become established in Australia. )
Lake levels in times of severe drought can sometimes fall below the desired level. This can be compensated for by the release of water from Googong Dam on the Queanbeyan River, a tributary of the Molonglo. The Queanbeyan River joins the Molonglo River at Oaks Estate just within the Australian Capital Territory. The Queanbeyan River joins the Molonglo River at Oaks Estate just within the Australian Capital Territory. Googong Dam was built in 1979 to cope with Canberra and Queanbeyan's growing water supply needs, and can contain up to 124,500 million litres of water. Queanbeyan is a city and local government area ( Queanbeyan City Council) in south eastern New South Wales, Australia. Water supply is the process of self-provision or provision by third parties of water of various qualities to different users 
Lake Burley Griffin is crossed by Commonwealth Avenue Bridge (310 m), Kings Avenue Bridge (270 m) and a roadway over Scrivener Dam. Commonwealth Avenue is a major road in Canberra, Australian Capital Territory, Australia. The two bridges were constructed before the lake was filled and are designed to allow the passage of recreational sailing boats with tall masts. Both bridges are dual-carriageway, Commonwealth Avenue has three lanes in each direction while Kings Avenue has two.
Site testing for both the Commonwealth Avenue Bridge and the Kings Avenue Bridge took place during late 1959 to early 1960.
Scrivener Dam is crossed by Lady Denman Drive, a narrow two lane roadway, and a bicycle path.

The water jet is powered by two 560 kilowatt electric motors driving four stage centrifugal pumps capable of pumping up to 250 litres per second against a head of 183 meters. The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. An electric motor uses Electrical energy to produce Mechanical energy. For information on Wikipedia project-related discussions see WikipediaVillage pump. The litre or liter (see spelling differences) is a unit of Volume. Hydraulic head is a specific measurement of water pressure or Total energy per Unit weight above a Geodetic datum. The water velocity at the water nozzle is 260 km/h. (For the South African airport with IATA code "KMH" see Johan Pienaar Airport. While running both pumps simultaneously the main jet throws approximately six tons of water into the air at any instant, reaching a maximum height of 147 metres. Alternatively the jet can be run on a single pump reaching a lower height of 110 metres. During special occasions it can be illuminated, often with coloured lights.
The water jet operates from 10–11. 45 a. m. in the morning and 2–3. 45 p. m. in the afternoon. During summer it also operates for an extra period from 7–9 p. m. . In periods of high wind the jet is automatically disabled as water landing on the nearby Commonwealth Avenue Bridge can be a hazard to traffic. The water jet must also be occasionally shut down when drought lowers the water level of the lake. 
Toxic blue-green algae blooms are unfortunately a reasonably common occurrence in the lake. Toxicity is the degree to which a substance is able to damage an exposed organism Cyanobacteria, also known as blue-green algae, blue-green bacteria or Cyanophyta, is a phylum of Bacteria that obtain their energy Warnings about coming into contact with the water are released when an algal bloom is detected. An algal bloom is a rapid increase in the population of Algae in an aquatic system Attempts are being made to limit the amount of phosphates entering the lake in the hope of improving its water quality. A phosphate, an Inorganic chemical, is a salt of Phosphoric acid.  Blue-green algae (more correctly cyanobacteria) produce toxins, which can be harmful for humans and any other animals that come in contact with the contaminated water. A toxin ( Greek:, toxikon, lit (poison for use on arrows is a Poisonous substance produced by living cells or organisms that is active at very low There have been several cases of dogs being affected after playing in and drinking the lake water. 
The water also appears murky due to a high level of turbidity, possibly a result of the bottom feeding of large numbers of introduced carp in the lake. Turbidity is the cloudiness or haziness of a fluid caused by individual particles ( suspended solids) that are generally invisible to the Naked eye The Common carp or European carp ( Cyprinus carpio) is a widespread freshwater Fish related to the common Goldfish ( Carassius auratus

Lake Burley Griffin, apart from being ornamental, is used for many recreational activities. Sailing and windsurfing are popular all year round. Sailing is the art of controlling a Sailing vessel. By changing the Rigging, Rudder and dagger or centre board a Sailor manages the force Windsurfing is a surface water sport using a windsurf board also commonly called a sailboard usually two to five meters long and powered by a single sail A rowing course is set up at the western end of the lake. Swimming is becoming less common due partly to concerns about water quality and generally cold water temperature. Swimming is the movement by humans or animals through Water, usually without artificial assistance Water quality is the physical chemical and biological characteristics of Water in relationship to a set of standards During summer, the lake is used for the swim leg of numerous triathlon and aquathlon events including the Sri Chinmoy Triathlon Festival.
Generally powerboat use on the lake is not permitted. A motorboat is a vessel propelled by an Internal combustion engine driving a jet pump or a Propeller. Permits are available for the use of powered boats on the lake for use in rescue, training, commercial purposes or special interest (historic steam powered boats, etc). A steamboat or steamship, sometimes called a steamer, is a ship in which the primary method of propulsion is steam power, typically driving a Propeller  Molonglo Reach, an area of the Molonglo River just before it enters the east basin is set aside for water skiing. Water skiing is a Sport where an individual (or more than one individual is pulled behind a Motor boat or a cable ski installation on a body of water wearing Powerboats may be used in this limited area. 
Fishing is quite popular in the lake with the most common species being the illegally introduced carp. For the computer security term see Phishing. Fishing is the activity of catching Fish. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. The Common carp or European carp ( Cyprinus carpio) is a widespread freshwater Fish related to the common Goldfish ( Carassius auratus The lake has been stocked annually with a variety of introduced and native species and over 1. 26 million fish have been released since 1964. Annual monitoring is carried out to determine fish populations. The 2001 survey only returned carp and redfin perch, both introduced species, and native golden perch. Carp is a common name for various Freshwater Fish of the family Cyprinidae, a very large The European perch ( Perca fluviatilis) is a highly predatory species of Perch found in Europe and Asia. The golden perch, Macquaria ambigua, is an Australian native freshwater Fish, primarily of the Murray - Darling river system However a number of less common species also inhabit the lake, including native Murray cod, western carp gudgeon and silver perch, as well as introduced goldfish, Gambusia, rainbow trout and brown trout.

There have been many changes to the fish populations in the lake as well as stocking practices since it was first filled. Stockings of introduced trout have been abandoned as the lake has proved to be a warm, eutrophic habitat that is not suited to the survival of introduced trout species. Trout is the common name given to a number of Species of Freshwater Fish belonging to the Salmonidae family A eutrophic lake (Eu meaning good/well and trophic meaning food/nutrients is a lake with high Primary productivity, the result of high Nutrient content
Regular stocking since the start of the 1980s have re-established reasonable populations of golden perch and highly elusive Murray cod; native fish that were indigenous to the Molonglo River before the lake was built, but had been lost to mining pollution of the Molonglo River in the 1930s and 1940s.

Russell is one of the smallest suburbs in Canberra comprising a number of government offices but no private Today golden perch and Murray cod are the only fish stocked in the lake. Murray cod are remarkable as freshwater fish for the extreme sizes they achieve and this is particularly the case for Lake Burley Griffin; specimens to approximately 38 kg have been recorded and there is no doubt there are a few even larger Murray cod in the lake.
The lake is patrolled by the Australian Federal Police water police. The National Carillon, situated on Aspen Island in central Canberra, Australia is a large Carillon managed and maintained by the National The Australian Federal Police (AFP is the Federal police agency of the Commonwealth of Australia. Water police, also called harbour patrols, port police, marine/maritime police, nautical patrols, bay constables or river police The water police give assistance to lake users, helping to right boats and towing crippled craft to shore.
At most swimming locations around Lake Burley Griffin there are fenced-in swimming areas for safety. In the more popular areas, there are also safety lockers with life belts and emergency phones for requesting help. A personal flotation device (also referred to as PFD, lifejacket, life preserver, Mae West, life vest, life saver, Between 1962 and 1991 seven people died from drowning in Lake Burley Griffin. 
For reasons of safety and water quality the lake is zoned for different activities in separate sections. The zoning for each section is as follows:
