Lake Walter E. Long
Lake Walter E. Long (also known as Decker Lake) is a power plant cooling reservoir on Decker Creek in Austin, Texas. The reservoir was officially impounded in 1967 and serves to provide water for turbines used in the production of electricity from petroleum-based fuels. The dam and the lake are managed by the City of Austin. Surrounding Lake Walter E. Long is the city of Austin's Lake Walter E. Long Metropolitan Park, a popular recreational destination. Flora and fauna Lake Walter E. Long has been stocked with species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in Lake Walter E. Long include catfish, largemouth bass, hybrid striped bass, and sunfish. Plant species present in the lake water include hydrilla, pondweed, bulrush Bulrush is a vernacular name for several large wetland grass-like plants *Sedge family (Cyperaceae): **''Cyperus'' **'' Scirpus'' **''Blysmus'' **''Bolboschoenus'' **'' Scirpoides'' **'' Isolepi ...

Thermal Power Station
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle. The design of thermal power stations depends on the intended energy source: fossil fuel, nuclear and geothermal power, solar energy, biofuels, and waste incineration are all used. Certain thermal power stations are also designed to produce heat for industrial purposes; for district heating; or desalination of water, in addition to generating electrical power. Fuels such as natural gas or oil can also be burnt directly in gas turbines (internal combustion). These pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrarchidae
Centrarchidae, better known as sunfishes, is a family of freshwater ray-finned fish belonging to the order Perciformes (formerly belonging to the deprecated order Centrarchiformes), native only to North America. There are eight universally included genera within the centrarchid family: ''Lepomis'' (true sunfishes), ''Micropterus'' (black basses), ''Pomoxis'' (crappies), ''Enneacanthus'' (banded sunfishes), ''Centrarchus'' (type genus, consisting solely of the flier ''C. macropterus''), ''Archoplites'' ( Sacramento perch), ''Ambloplites'' (rock basses), and ''Acantharchus'' (mud sunfish). A genetic study in 2012 suggests that the highly distinct pygmy sunfishes of the genus ''Elassoma'' are also centarchids. The centrarchid family comprises 38 identified species, 34 of which are extant. It includes many popular game fishes familiar to North American anglers, such as the rock bass, largemouth bass, bluegill, pumpkinseed, green sunfish and crappies. Most sunfish are highly valu ...

Reservoirs In Texas
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Najas Guadalupensis
''Najas guadalupensis'' is a species of aquatic plant known by the common names southern waternymph, guppy grass, najas grass, and common water nymph. It is native to the Americas, where it is widespread. It is considered native to Canada (from Alberta to Quebec), and most of the contiguous United States, Mexico, Central America, the West Indies and South America. It has been introduced in Japan, Israel and Palestine. ''Najas guadalupensis'' is an annual, growing submerged in aquatic habitat types such as ponds, ditches, and streams. It produces a slender, branching stem up to 60 to 90 centimeters in maximum length. The thin, somewhat transparent, flexible leaves are up to 3 centimeters long and just 1 or 2 millimeters wide. They are edged with minute, unicellular teeth. Tiny flowers occur in the leaf axils; staminate flowers grow toward the end of the plant and pistillate closer to the base. They are also a popular aquarium plant for beginners due to their hardiness as well as gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratophyllum
''Ceratophyllum'' is a cosmopolitan genus of flowering plants including four accepted living species in 2016, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant genus in the family Ceratophyllaceae, itself the only extant family in the order Ceratophyllales. They are usually called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta. ''Ceratophyllum'' grows completely submerged, usually, though not always, floating on the surface, and does not tolerate drought. The plant stems can reach 1–3 m in length. At intervals along nodes of the stem they produce rings of bright green leaves, which are narrow and often much-branched. The forked leaves are brittle and stiff to the touch in some species, softer in others. Roots are completely absent and are missing even in the embryonic stage, but sometimes they develop modified leaves with a rootlike appearance, which anch ...

Nelumbo Lutea
''Nelumbo lutea'' is a species of flowering plant in the family Nelumbonaceae. Common names include American lotus, yellow lotus, water-chinquapin, and volée. It is native to North America. The botanical name ''Nelumbo lutea'' Willd. is the currently recognized name for this species, which has been classified under the former names ''Nelumbium luteum'' and ''Nelumbo pentapetala'', among others. Description American lotus is an emergent aquatic plant. It grows in lakes and swamps, as well as areas subject to flooding. The roots are anchored in the mud, but the leaves and flowers emerge above the water's surface. The petioles of the leaves may extend as much as and end in a round leaf blade in diameter. Mature plants range in height from . Flowering begins in late spring and may continue into the summer. The specific name means "yellow" in Latin and refers to the flowers, which may be white to pale yellow. The flowers measure in diameter and have 22-25 petals. It is t ...

Heteranthera Dubia
''Heteranthera dubia'', commonly called water stargrass or grassleaf mudplantain, is a species of aquatic plant in the pickerel-weed family (Pontederiaceae). It is native to North and Central America where it is widespread from Canada to Guatemala. It lives submerged in freshwater such as rivers and lakes. It can be found as deep as 5.5 meters, to as shallow as stranded on the shoreline. It is most abundant in alkaline waters. ''Heteranthera dubia'' is a perennial with much variation in its appearance. The leaves are different sizes and shapes across individuals, partly genetic variation and partly response to water conditions, for example, the speed and turbulence of surrounding currents. Submersed individuals also have a different stem and leaf morphology from those that occur partially or completely out of the water. Its inflorescence bears a single short-lived flower that blooms in the morning and wilts in the evening. It has six yellow perianth parts each less than a centim ...
