Bill Gunn Dam
The Bill Gunn Dam is an earth-fill embankment dam with an un-gated spillway located off-stream in Laidley Heights in the South East region of Queensland, Australia. The main purpose of the dam is for irrigation of the Lockyer Valley. The resultant reservoir is called Lake Dyer. Location and features Located west of the town of Laidley, the dam was developed to increase the capacity of the existing Lake Dyer, a natural lake adjacent to Laidley Creek, a tributary of Lockyer Creek. The dam was named after the Queensland politician Bill Gunn and is managed by SEQ Water. The long earthfill structure has a maximum height of and an overflow spillway which diverts excess water into Laidley Creek. The dam has a storage capacity of and a maximum surface area of . Water from the dam is used for irrigation, in the densely cropped Lockyer Valley. Bill Gunn Dam suffers from high drawdowns and summer evaporation which together with phosphate fertilizer creates significant blue gr ...

Laidley Heights, Queensland
Laidley Heights is a rural residential locality on the outskirts of the town of Laidley in the Lockyer Valley Region, Queensland, Australia. In the , Laidley Heights had a population of 1,429 people. Geography The locality is bounded to the east by Laidley Creek. Lake Dyer is in the east of the locality (). Although it is a natural lake, its capacity to store water was increased by the construction of the Bill Gunn Dam (), a earth embankment with a central clay core. As well as the natural inflows to the lake, additional water from Laidley Creek is redirected into Lake Dyer for storage. It is an ungated dam so it commences spilling whenever it is full. The land use is a mix of rural residential housing in the central areas of the locality, irrigated horticulture in the east along the creek, and grazing on native vegetation in the remainder of the locality. History The locality was named after the town of Laidley, which, in turn, was derived from the naming of Laidleys P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outbreak
In epidemiology, an outbreak is a sudden increase in occurrences of a disease when cases are in excess of normal expectancy for the location or season. It may affect a small and localized group or impact upon thousands of people across an entire continent. The number of cases varies according to the disease-causing agent, and the size and type of previous and existing exposure to the agent. Outbreaks include many epidemics, which term is normally only for infectious diseases, as well as diseases with an environmental origin, such as a water or foodborne disease. They may affect a region in a country or a group of countries. Pandemics are near-global disease outbreaks when multiple and various countries around the Earth are soon infected. Definition The terms "outbreak" and "epidemic" have often been used interchangeably. Researchers Manfred S. Green and colleagues propose that the latter term be restricted to larger events, pointing out that '' Chambers Concise Dictionary'' and ...

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.

Bidyanus Bidyanus
The silver perch (''Bidyanus bidyanus'') is a medium-sized freshwater fish of the family Terapontidae endemic to the Murray-Darling river system in south-eastern Australia. A threatened species, in 2024 the Australian Government reassessed the silver perch's conservation status using IUCN Criteria. The result was a re-listing of the species as Endangered under the EPBC Act (Australia's national environmental law), in striking contrast to a 2019 IUCN assessment suggesting the species was merely 'Near Threatened'. Taxonomy The silver perch's scientific name comes from an aboriginal name for the species – ''bidyan'' – recorded by Major Mitchell on the Barwon River on his 1832 expedition. (Mitchell's original scientific name for the species was ''Cernua Bidyana''.) Silver perch are not a "true" perch of the genus ''Perca'', but are instead a member of Terapontidae or 'grunter' family. They are the largest member of the Terapontidae, capable of growing in excess of and clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Stocking
Fish stocking is the practice of releasing fish that are artificially raised in a fish hatchery, hatchery into a natural body of water (river, lake, or ocean), to supplement existing wild populations or to create a new population where previously none exists. Stocking may be done for the benefit of commercial fishing, commercial, recreational fishing, recreational or tribal artisan fishing, heritage fishing, but may also be done for ecological conservation to restore or increase the population of threatened species, threatened/endangered species, endangered fish species that is pressured by prior overfishing, habitat destruction, and/or competition (biology), competition from invasive species. Fish stocking may be conducted by governmental fisheries management agencies, non-profit organizations, and voluntary associations in public waters, or by for-profit corporation, for-profit NGOs, clubs and commercial enterprises in privately owned waters. When in public waters, fish stocking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boat Ramp
A slipway, also known as boat ramp or launch or boat deployer, is a Inclined plane, ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on Boat trailer, trailers towed by automobiles and flying boats on their Landing gear, undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is Ship breaking, scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's Hull (watercraft), hull is coated with Grease (lubricant), grease, which then allows the ship or boat to "slip" off the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
