Innerstetalsperre
The Innerste Dam () is a dam on the Innerste river, which lies near Langelsheim and Wolfshagen in the Harz mountains. It was built between 1963 and 1966 and belongs to the ''Harzwasserwerke''. Its purposes are the supply of drinking water, flood protection, water flow regulation and hydroelectric power generation. The average annual discharge through the Innerste Dam is 60 million m³. Structures The Innerste is an earth-fill dam with multiple, external, asphaltic concrete layers. It has an inspection gangway along its whole length on the upstream apron. In front of the upstream base of the dam is a shaft spillway (a flood overflow tower), into which also the bottom outlet is integrated. The water of the Innerste Dam can be pumped via a 4.6 km long diversion channel to the Grane Dam further east, where it can be used for water treatment. From 2003 to 2005 the reservoir was completely emptied and renovated, especially the asphalt sealing and the bottom outlet. This work w ...

Innerste
The Innerste () is a river in Lower Saxony, Germany. It is a right tributary of the Leine river and in length. Origin of the name The river name is not related to the German word ''innerste'' meaning innermost. ''Innerste'', in earlier times called the ''Inste'' (1805), ''Inderste'' (1567), ''Indistria'' (1313), ''Entrista'' (1065) and ''Indrista'' (1013), probably goes back to the Indo-Germanic root ''oid'' = ''turbulent, strong''. It may be the name referred to in the name of the battlefield of ''Idistaviso, ''Idista''viso'' (16 A.D.). Course The river's source is in the Harz mountains, from the town of Clausthal-Zellerfeld to the southwest at an elevation of 615 m and is called ''Innerstesprung''. As a small brook, the Innerste flows west and passes a system of lakes, the first of which is called ''Entensumpf''. The next lakes are ''Oberer Nassenwieser Teich'', ''Bärenbrucher Teich'', ''Ziegenberger Teich'', and ''Sumpfteich''. The German word ''Teich'' means "p ...

Water Treatment
Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use. Types Drinking water treatment Water contamination is primarily caused by the discharge of untreated wastewater from enterprises. The effluent from various enterprises, which contains varying levels of contaminants, is dumped into rivers or other water resources. The wastewater may have a high proportion of organic and inorganic contaminants at the initial discharge. Industries generate wastewater as a result of fabrica ...

Dams In The Harz
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

List Of Reservoirs And Dams In Germany
These are dams and reservoirs in Germany. The German word ''Talsperre'' (literally: valley barrier) may mean dam, but it is often used to include the associated reservoir as well. The reservoirs are often separately given names ending in ''-see'', ''-teich'' or ''-speicher'' which are the German words for "lake", "pond" and "reservoir", but in this case all may also be translated as "reservoir". The more specific word for the actual dam is ''Staumauer'' and for the lake is ''Stausee''.

List Of Dams In The Harz
In the Harz mountains, there is a higher than average number of dams with their associated Reservoir, reservoirs. The reason is that the Harz is one of the regions with the heaviest rainfall in Germany and so its water power was utilised very early on. The first dam (on the Upper Harz Ponds) was built to drive water-powered pumps and stamp mills used in the Mining, mines. At present, the Harz reservoirs provide Hydro-electricity, hydroelectricity, drinking water and flood protection particularly when the snows melt in spring. The following is a list of dams in the Harz: * Ecker Dam which impounds the waters of the Ecker * Grane Dam which impounds the waters of the Grane (river), Grane * Hassel Auxiliary Dam which impounds the waters of the Hassel (river), Hassel, is part of the Rappbode Dam, Rappbode Dam system * Innerste Dam which impounds the waters of the Innerste * Kelbra Dam which impounds the waters of the Helme (river), Helme * Königshütte Dam impounds the waters of bot ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. 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 reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grane Dam
The Grane Dam () is a dam above the village of Astfeld/Herzog-Juliushütte in the borough of Langelsheim in the Lower Saxon part of the Harz mountains. Dam system It is the newest dam in the Harz, built in 1969 in the Grane valley. Because the river Grane itself does not deliver enough water for the 3 km long reservoir, a 7.4 km long diversion channel was built from the Oker river below the Oker Dam. This also collects water from the Gose on the way. A further 4.8 km long diversion runs from the Radau to the Großer Romke and thus into the Oker-Grane Tunnel as well. Likewise there is a 4.6 km long tunnel to the Innerste Dam. The operator of the Grane Dam, as well as its associated diversion systems and waterworks is the '' Harzwasserwerke''. The barrage is an earth dam with asphaltic concrete lining. Reservoir The Grane Reservoir (''Granestausee'') supplies drinking water, acts as flood protection, water regulation and electricity generation. Th ...
