Sog River
Sog (; more commonly Sogið ) is a river in Iceland. It runs from the lake Þingvallavatn for to its confluence with the river Hvítá, forming the river Ölfusá which then runs for another 25 km into the Atlantic Ocean. Its average discharge is . There are three hydroelectric power stations on the riverLjósafossstöð (15 MW)Írafossstöð (48 MW) anSteingrímsstöð (27 MW). The river runs through two lakes, Úlfljótsvatn and Álftavatn . It has a healthy stock of arctic char and Atlantic salmon. The size of the char can be anywhere from 0.5 pounds up the 5.0 pounds with an average size of one pound. The most common weight for salmon is 5.0 to 10.0 pounds with a few fish caught each year from 20.0 to 30.0 pounds. There are also brown trout Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', '' Salmo'' and '' Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Þingvallavatn
Þingvallavatn (), anglicised as Thingvallavatn,The spelling ''Pingvallavatn'' is wrong as the letter “p” should never be used to represent the letter “þ” (thorn). is a rift valley lake in southwestern Iceland. With a surface of 84 km² it is the second largest lake in Iceland. Its greatest depth is 114 m. At the northern shore of the lake, at Þingvellir (after which the lake is named), the Alþingi, the national parliament, was founded in the year 930, and held its sessions there until 1799 and still as of today the name Alþingi Íslendinga is carried by the parliament of Iceland. The lake lies partially within Þingvellir National Park. The volcanic origin of the islands in the lake is clearly visible. The cracks and faults around it, of which the Almannagjá ravine is the largest, is where the Eurasian and North American tectonic plates meet. Silfra fissure is a popular scuba and snorkeling site. The only outflow from lake Þingvallavatn is the river Sog. One ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ölfusá
The Ölfusá () is a river in Iceland. It begins at the junction between the Hvítá and Sog rivers, just north of the town of Selfoss, and flows for 25 km into the Atlantic ocean. It is Iceland's largest river by volume with an average discharge of 423 m³/s. Its drainage basin is 5760 km2. The Ölfusá is home to a large salmon fishing industry. The Flói Nature Reserve is located on its eastern shore near its mouth. See also *List of rivers of Iceland On an island like Iceland, the rivers are short in length.

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World The term ''New World'' is often used to mean the majority of Earth's Western Hemisphere, specifically the Americas."America." ''The Oxford Companion to the English Language'' (). McArthur, Tom, ed., 1992. New York: Oxford University Press, p. ..." of the Americas in the European perception of Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Úlfljótsvatn (lake)
Úlfljótsvatn (, ''Úlfljótr's Lake'') is a lake in southern Iceland, to the south of lake Þingvallavatn, 74km east of Reykjavík. Úlfljótsvatn is named after Úlfljótr, an important man who was involved in the Alþingi (Icelandic Parliament) in 930. In the vicinity, the Icelanders have many summer cottages. Geography The lake has an area of 3.6 km² and is situated at an altitude of 80 m. At the deepest point, Úlfljótsvatn is about 34.5 meters deep. The lake has a water area of 3.6 km² and is located directly south of the larger lake Þingvallavatn on the Sog river, which continues to Álftavatn. The lake in the warm season attracts anglers. Trout and lake char can be found in the waters of the lake. History Orkuveita Reykjavíkur bought the rights in 1929-1933 to generate electricity in the upper run of the Sog. In 1937, the Ljósafoss power station was then built, increasing the water level by about 1 metre. The Icelandic Scout and Guides Association has had i ...

Salvelinus
''Salvelinus'' is a genus of salmonid fish often called char or charr; some species are called "trout". ''Salvelinus'' is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea. Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115-200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout (''S. namaycush'') and arctic char (''S. alpinus'') are objects of commercial fisheries and/or aquaculture. Occasionally, such fish escape and become invasive species. Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They are highly s ...

Salmon
Salmon () is the common name for several commercially important species of euryhaline ray-finned fish from the family Salmonidae, which are native to tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus '' Oncorhynchus'') basin. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen. Salmon are typically anadromous: they hatch in the gravel beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems; the percent of straying depends on the species of salmon. Homing behavior has been shown to depend on ...

Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', '' Salmo'' and '' Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
