Chelmer Reach
The Brisbane River is the longest river in South East Queensland, Australia, and flows through the city of Brisbane, before emptying into Moreton Bay on the Coral Sea. John Oxley, the first European to explore the river, named it after the Governor of New South Wales, Sir Thomas Brisbane in 1823. The penal colony of Moreton Bay later adopted the same name, eventually becoming the present city of Brisbane. The river is a tidal estuary and the water is brackish from its mouth through the majority of the Brisbane metropolitan area westward to the Mount Crosby Weir. The river is wide and navigable throughout the Brisbane metropolitan area. The river travels from Mount Stanley. The river is dammed by the Wivenhoe Dam, forming Lake Wivenhoe, the main water supply for Brisbane. The waterway is a habitat for the rare Queensland lungfish, Brisbane River cod (extinct), and bull sharks. Early travellers along the waterway admired the natural beauty, abundant fish and rich vegetation a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Brisbane
Major General Sir Thomas Makdougall Brisbane, 1st Baronet, (23 July 1773 – 27 January 1860), was a British Army officer, administrator, and astronomer. Upon the recommendation of the Duke of Wellington, with whom he had served, he was appointed governor of New South Wales from 1821 to 1825. A keen astronomer, he built the colony's second observatory and encouraged scientific and agricultural training. Rivals besmirched his reputation and the British Secretary of State for the Colonies, Lord Bathurst, recalled Brisbane and his colonial secretary Frederick Goulburn. Brisbane, a new convict settlement, was named in his honour and is now the 3rd largest city in Australia. Early life Brisbane was born at Brisbane House in Noddsdale, near Largs in Ayrshire, Scotland, the son of Sir Thomas Brisbane and his wife Eleanora (née Bruce). He was educated in astronomy and mathematics at the University of Edinburgh. He joined the British Army's 38th (1st Staffordshire) Regiment of Foot ...

Bulimba Creek
Bulimba Creek, originally known as Doboy Creek or Doughboy Creek, is a perennial stream that is a tributary of the Brisbane River, located in suburban Brisbane in the South East region of Queensland, Australia. Course and features The Bulimba Creek catchment has it sources in the low plateaus and marshy parts of the suburbs of and Runcorn (west catchment) and Kuraby (east catchment) in the south of Brisbane. It then flows in a northerly direction through the suburbs of Mansfield, Mackenzie, Carindale, Murarrie and Lytton, before meeting the Brisbane River via the Aquarium Passage along the Lytton Reach. The creek has six tributaries: Mimosa Creek, Spring Creek, Salvin Creek, Phillips Creek, Tingalpa Creek and Lindum Creek. There are also a number of significant wetlands systems in the catchment, including Runcorn Wetlands in the upper catchment and Numgubbah, Tingalpa, Doboy and Lindum Wetlands in the lower catchment. The creek is currently impacted primarily by urban and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brisbane River Cod
The Brisbane River cod was a unique form of ''Maccullochella'' cod that occurred naturally in the Brisbane River system, an east coast river system in south east Queensland, Australia. The Brisbane River Cod was known as the Bumgur (meaning blue cod) by the Jinibara people centred in the Kilcoy region and the junction of the Stanley and Brisbane Rivers. Their exact taxonomic status is not known, but based on several genetic studies it is suspected that Brisbane River Cod were a species intermediate between eastern freshwater cod (''Maccullochella ikei'') of the Clarence River and Richmond River systems in northern New South Wales and Mary River cod of the Mary River in central Queensland. All naturally occurring ''Maccullochella'' cod in east coast drainages ultimately originate from Murray cod, ''Maccullochella peelii'' that entered an east coast river system, likely the Clarence, via a natural river capture event somewhere between 0.62 and 1.62 million years ago (mean estim ...

Queensland Lungfish
The Australian lungfish (''Neoceratodus forsteri''), also known as the Queensland lungfish, Burnett salmon and barramunda, is the only surviving member of the family Neoceratodontidae. It is one of only six extant lungfish species in the world. Endemic to Australia, the Neoceratodontidae are an ancient family belonging to the class Sarcopterygii, or lobe-finned fishes. Fossil records of this group date back 380 million years, around the time when the higher vertebrate classes were beginning to evolve. Fossils of lungfish almost identical to this species have been uncovered in northern New South Wales, indicating that ''Neoceratodus'' has remained virtually unchanged for well over 100 million years, making it a living fossil and one of the oldest living vertebrate genera on the planet. It is one of six extant representatives of the ancient air-breathing Dipnoi (lungfishes) that flourished during the Devonian period (about 413–365 million years ago) and is the outgroup to all ...

Navigability
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Such a navigable water is called a ''waterway'', and is preferably with few obstructions against direct traverse that needed avoiding, such as Rock (geology), rocks, reefs or trees. Bridges built over waterways must have sufficient air draft, clearance. High discharge (hydrology), flow speed may make a channel (geography), channel unnavigable due to risk of ship collisions. Waters may be unnavigable because of ice, particularly in winter or high-latitude regions. Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger cargo ship, freighter or cruise ship. Shallow rivers may be made navigable by the installation of canal locks, locks that regulate flow and increase upstream water level, or by dredging that deepens parts of the stream bed. Inland w ...

Mount Crosby Weir
The Mount Crosby Weir is a heritage-listed weir on the Brisbane River at Mount Crosby and Chuwar, both in City of Brisbane, Queensland, Australia. The project was instigated by John Petrie at the end of the 19th century. The town of Brisbane was expanding and seeking more reliable sources of drinking water than Enoggera Dam and Gold Creek Dam could provide. In conjunction with the Mount Crosby Pumping Station, it was listed on the Queensland Heritage Register on 25 October 2019. Location and features The location was selected because it was just above the upstream tidal flow of seawater at Colleges Crossing. The concrete structure was completed in April 1892. The dam wall rises and is in length. The weir has a capacity of , making it one of the largest weirs in the region. Above the weir is a one-lane road which is open to the public. The nearby Mount Crosby Pumping Station is used to transport drinking water that is sourced from both the weir and the nearby Lake Manchester ...

Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moreton Bay Penal Colony
The Moreton Bay Penal Settlement operated from 1825 to 1842. It became the city of Brisbane, Queensland, Australia. History The Moreton Bay Penal Settlement was established on the Redcliffe Peninsula on Moreton Bay in 1824, under the instructions of John Oxley that a suitable location would be "easy of access, difficult to escape from, and hard to attack; furthermore, it should be near fresh water and contain three hundred acres for cultivation". Only one year after settlement, the inadequacy of Redcliffe's water supply became apparent and in May 1825 the commandant Lieutenant Henry Miller decided to relocate the settlement to the current Brisbane CBD. Located on the north bank of the Brisbane River, the new site allowed the collection of water from a freshwater creek and a chain of water holes near the present Roma Street railway station, the first substantial water supply within of the mouth of the Brisbane River. This was an elevated location with cooling breezes. The sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governors Of New South Wales
The governor of New South Wales is the viceregal representative of the Australian monarch, King Charles III, in the state of New South Wales. In an analogous way to the governor-general of Australia at the national level, the governors of the Australian states perform constitutional and ceremonial functions at the state level. The governor is appointed by the king on the advice of the premier of New South Wales, and serves in office for an unfixed period of time—known as serving ''At His Majesty's pleasure''—though five years is the general standard of office term. The current governor is retired jurist Margaret Beazley, who succeeded David Hurley on 2 May 2019. The office has its origin in the 18th-century colonial governors of New South Wales upon its settlement in 1788, and is the oldest continuous institution in Australia. The present incarnation of the position emerged with the Federation of Australia and the ''New South Wales Constitution Act 1902'', which defined the ...
