Zillierbach Reservoir
The Zillierbach (until 1558 called the Zilgerbach) is a stream in the Harz mountains of central Germany (Harz district) in the state of Saxony-Anhalt. It is about long. The stream rises on the western side of the ''Hohneklippen'' crags and runs initially southwards, then swings northeast at Drei Annen Hohne. South of Drei Annen Hohne it picks up the waters of the Wormsgraben, its main tributary. The Zillierbach supplies the Zillierbach Dam near Elbingerode. In front of the settlement of Voigtstieg it is joined by another two smaller brooks. In the Middle Ages the Zillierbach powered the mills between Voigtstieg and Wernigerode. This section of the valley is still called ''Mühlental'' (Mill Valley) today. In its lower reaches before its mouth the stream is known as the ''Flutrenne''. The stream discharges into the Holtemme at Wernigerode northwest of the West Gate (''Westerntor''). It drops through a vertical height of almost from source to mouth. Habitat and ecology The ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of The Harz
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Federal Ministry For Environment, Nature Conservation And Nuclear Safety
The Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (german: Bundesministerium für Umwelt, Naturschutz, nukleare Sicherheit und Verbraucherschutz, ), abbreviated BMUV, is a cabinet-level ministry of the Federal Republic of Germany. It has branches in Bonn and Berlin. The ministry was established on 6 June 1986 in response to the Chernobyl disaster. The then Federal Government wanted to combine environmental authority under a new minister in order to face new environmental challenges more effectively. Furthermore The Greens had been formed a few years prior in part as an anti-nuclear environmentalist party and had achieved federal representation in 1983 and Joschka Fischer had been appointed minister of the environment for Hesse the previous year, marking the first state level red-green coalition in Germany. Thus the CDU/CSU intended to project a message of taking the environment seriously in an era in which the Greens wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Ladder
A fish ladder, also known as a fishway, fish pass, fish steps, or fish cannon is a structure on or around artificial and natural barriers (such as dams, locks and waterfalls) to facilitate diadromous fishes' natural migration as well as movements of potamodromous species. Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ''ladder'') into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver. History Written reports of rough fishways date to 17th-century France, where bundles of branches were used to make steps in steep channels to bypass obstructions. A pool and weir salmon ladder was built around 1830 by James Smith, a Scottish engineer on the River Teith, near Deanston, Perthshire ...

Cobitidae
Cobitidae, also known as the True loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families (see below). The family includes about 260 described species. New species are being described regularly.Perdices, A., Bohlen, J., Šlechtová, V. & Doadrio, I. (2016): Molecular Evidence for Multiple Origins of the European Spined Loaches (Teleostei, Cobitidae). ''PLoS ONE, 11 (1): e0144628.'' Description and ecology The body forms of the Cobitidae tend to be vermiform – worm-shaped, long and thin. Most true loaches do not have true scales, and like many other Cypriniformes or catfishes, they have barbels at their mouths (usually three to six pairs). Some other traits typically found in this family are a small bottom-facing mouth suited to their scavenging benthic lifestyle, an erectile spine below the eye, and a single row of pharyngeal (throat) teeth.

Gudgeon (fish)
Gudgeon is the common name for a number of small freshwater fish of the families Butidae, Cyprinidae, Eleotridae or Ptereleotridae. Most gudgeons are elongate, bottom-dwelling fish, many of which live in rapids and other fast moving water. Families * Cyprinidae – Various cyprinid gudgeons, members of the subfamily Gobioninae (e.g. genera ''Gobio'', '' Romanogobio''), are found in lakes and rivers throughout Europe. Most commonly gudgeon refers to the species ''Gobio gobio''. This is a rheophilic and schooling species that occurs both in river and lake habitats across continental Europe and the United Kingdom. ''G. gobio'' feeds on a variety of invertebrates. This gudgeon is an easy fish to catch for beginners. A British rod caught a record 5 ounce gudgeon in 1990 on the River Nadder, Wiltshire. * Eleotridae – Known commonly as gudgeons, many species in the family Eleotridae are also called sleeper gobies. Unlike gobies, Eleotridae gudgeons have paired ventral fins rather t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Minnow
The Eurasian minnow, minnow, or common minnow (''Phoxinus phoxinus'') is a small species of freshwater fish in the carp family Cyprinidae. It is the type species of genus ''Phoxinus''. It is ubiquitous throughout much of Eurasia, from Britain and Spain to eastern Siberia, predominantly in cool () streams and well- oxygenated lakes and ponds. It is noted for being a gregarious species, shoaling in large numbers. Description The common minnow is a small fish which reaches a maximum total length of , but is normally around in length. It has 3 spines and 6–8 soft rays in its dorsal fin with 3 spines and 6–8 soft rays in its anal fin. Its spine is made up of 38–40 vertebrae. It is distinguished from similar species which occur in Europe by having the lateral line normally extending beyond the nase of the anal fin, by a line of vertically elongated blotches along the lateral line each with a depth equivalent to 1/3–1/2 of the body's depth at same position, these ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
