Atkinson Dam
The Atkinson Dam is an earth-fill embankment dam across the Buaraba Creek and a naturally forming lagoon, which is located near Lowood in the South East region of Queensland, Australia. The main purpose of the dam is for irrigation of farming land in the lower Lockyer Valley. The resultant reservoir is called Lake Atkinson. Location and features Located in the locality of Atkinsons Dam, northeast of in the Somerset Region local government area of West Moreton region, the dam wall was constructed in 1970 over the natural Atkinsons Lagoon. The dam wall is high and long and holds back of water when at full capacity. The surface area of the reservoir is and the catchment area is . The uncontrolled spillway has a discharge capacity of . The dam is connected to Seven Mile Lagoon via a channel. Facilities at the dam include two boat ramps, picnic tables and two caravan parks. A maximum of 15 boats are permitted on the lake at any one time. In mid-2006 the dam was empty due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caravan Parks
A recreational vehicle park (RV park) or caravan park is a place where people with recreational vehicles can stay overnight, or longer, in allotted spaces known as "sites" or "campsites". They are also referred to as campgrounds, though a true campground also provides facilities for tent camping; many facilities calling themselves "RV parks" also offer tent camping or cabins with limited facilities. Services Allocated space (pitch/site) facilities may include: * AC power connection. (Usually rated by capacity such as 15, 20, 30 or 50 amperes.) * Drinking water connection * Sewer connection * Television connection (relevant to local area standards) * Telephone connection (rare outside North America) * Hotspot (Wi-Fi) Park facilities may include: * Barbecue area * Bathhouses * Convenience store * Dump station * Exercise equipment * Gift shop * Golf Courses * Hot tubs * Laundry * Picnic tables * Restrooms * Recreation Hall * Showers * Swimming pool * Bar/restauran ...

Eel-tailed Catfish
The eel-tailed catfish, ''Tandanus tandanus'', is a species of catfish (order Siluriformes) of the family Plotosidae. This fish is also known as dewfish, freshwater catfish, jewfish, and tandan. This species is a freshwater fish native to the Murray- Darling river system of eastern Australia. The scientific name for eel-tailed catfish comes from a name for the fish in an unidentified Aboriginal Australian language - ''Tandan'' - which Major Thomas Livingston Mitchell recorded on his 1832 expedition. Description Eel-tailed catfish commonly grow to about 50.0 centimetres (19.7 in) and weigh about 1.8 kilograms (4.0 lb). Fish of this species may grow up to about 90.0 cm (35.4 in) and weigh up to 6.0 kg (13.2 lb). Eel-tailed catfish may live up to about 8 years.

Bayswater, Victoria
Bayswater is a residential and industrial suburb in Melbourne, Victoria, Australia, east of Melbourne's Central Business District, located within the City of Knox local government area. Bayswater recorded a population of 12,262 at the 2021 census. History The first Post Office in the area was Scoresby North, which opened on 8 May 1882 and renamed Macauley in 1884. When the railway arrived in 1889, a Bayswater office near the station replaced Macauley. In 1998 Bayswater Village (at the shopping centre of that name) office replaced Bayswater. In the late 1940s, a number of German Templers (just released from the Tatura Internment Camp) settled in Bayswater and Boronia. Part of the Temple Society Australia, they built a Community Centre (1961) in Elizabeth Street and a Retirement Village, as well as Nursing HomTabulam in partnership with the Australian German Welfare Society (AGWS). The Bayswater Wine Cellar is the oldest building in the region, erected in the mid 19th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen Depletion
Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure. In water, oxygen levels are much lower, approximately 7 ppm or 0.0007% in good quality water, and fluctuate locally depending on the presence of photosynthetic organisms and relative distance to the surface (if there is more oxygen in the air, it will diffuse across the partial pressure gradient). Atmospheric hypoxia Atmospheric hypoxia occurs naturally at high altitudes. Total atmospheric pressure decreases as altitude increases, causing a lower partial pressure of oxygen, which is defined as hypobaric hypoxia. Oxygen remains at 20.9% of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air (or blood) is decreased. This is common in the sealed burrows of some subterranean animals, such as blesmols. Atmospheric hypoxia is also the basis of altitude tra ...

Evaporation
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it will escape and enter the surrounding air as a gas. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid. The evaporation will continue until an equilibrium is reached when the evaporation of the liquid is equal to its condensation. In an enclosed environment, a liquid will evaporate until the surrounding air is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Perch
The golden perch (''Macquaria ambigua'') is a medium-sized, yellow or gold-coloured species of Australian freshwater fish found primarily in the Murray-Darling River system, though a subspecies is found in the Lake Eyre-Cooper Creek system, and another subspecies, suspected to be ancestral to all other populations, is found in the Fitzroy River system in Queensland. Other common names for golden perch are "goldens", “yellowbelly” and "callop", the last generally used only in South Australia. Golden perch are not a true perch, which belongs to the genus ''Perca'' from the family Percidae, but a member of the Percichthyidae (temperate perch) family. This relatively widespread and widely stocked species is an important angling sport fish in Australia. Description Golden perch are medium-sized fish, commonly 30–40 cm and 1–2 kg in rivers. Fish from rivers are smaller and somewhat streamlined — fish in man-made impoundments are much deeper-bodied and show much ...

Southern Saratoga
The southern saratoga (''Scleropages leichardti''), also known as the spotted bonytongue, spotted saratoga, or simply saratoga, is a freshwater bony fish native to Australia. It belongs to the subfamily Osteoglossinae, or arowanas, a primitive group of teleosts. Like all arowanas, it is a carnivorous mouthbrooder. Along with the gulf saratoga (''Scleropages jardinii''), the saratoga is also known as the Australian arowana (mainly by non-Australian aquarists) and barramundi, although the latter name is nowadays reserved in Australia for the unrelated ''Lates calcarifer''. This species is found in turbid waters and has a more restricted distribution than the other ''Scleropages'' native to Australia, ''Scleropages jardinii''. Description Southern saratoga can grow up to . At sexual maturity, they are usually in length. They are primitive, surface-dwelling fish with strongly compressed bodies. They have an almost perfectly flat back, with a dorsal fin set back towards the tail of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
