Schaale

The Schaale is a 40 kilometer long tributary of the brews in the west of Mecklenburg-Vorpommern and the natural flow of Schaalsees.

Course

The Schaale occurs on the south bank of over a weir in 1980 decommissioned Schaalmühle from the Schaalsee and extends southward initially by a Sander area. In Schaalmühle their flows on the left side of the hammer to Bach from the Boissower lake. South of Kogel opens the Small Schaale, north of Vietow the lazy river and south of Benninger shields one. From here on, the slope decreases and the river forms meanders. In Zahrensdorf the Schaale reached the Elbe river valley and the natural park Mecklenburgisches Elbetal. From chicken Busch course of the river is largely straightened, the original river bed is obtained and forms tributaries. The underflow is often characterized by wooded dunes trains and managed, in the spring of flooded wet meadows. Southeast of Gülze opens the Schaale in the Sude, in turn, a few kilometers to the west drains into the Elbe.

The long-term average discharge at the mouth is 3.4 m³ / s The discharged water volumes of Schaale come only to a small extent directly from the Schaalsee, mainly they come from shore -based sources and tributaries of the total of 686 km ² catchment area.

The entire course of Schaale and adjacent areas are provided by the designation of conservation areas and Schaalelauf Schaaleniederung under legal protection. The channelized river south of Blücher is within the NSG Sudeniederung between Boizenburg and possession.

History

Name

The Schaale is mentioned in a document from 1279 scales. A Namensherleitung is possible from the old Slavic or Polish scale for Stone, Rock ( altsl. ) or Cliff, Rock (Polish ). Accordingly, the name Schaale stands for the Stony / Steinbach.

Formation

The Schaale originated as meltwater flow of Eisvorstoßes the Frankfurt stage of the Weichsel glaciation. It mostly runs in one to ten meters into the Sander sunken Kastental with distinct, different old sliding and impact slopes and terraces. In the course of the river occurring boulders and gravel caused by free rinses saale cold temporal Moränezüge.

Use history

In the period 1564 to 1830 the river was regulated by 13 jam and box locks. The Schaale was important in the 17th century trade route for salt waterways, which Zarrentin approached the function of a market town. Also the Lüneburg Saltworks was supplied with acquired along the river and transporting wood sailed. It was only after the closure of the Lueneburg Saline in 1830 it came to reforestation.

At times, the idea was pursued in competition with the Stecknitz channel, Wismar for purposes of navigation to connect to the Schaalsee to go over the Schaale the Elbe. This was in 1588 for Lübeck occasion to summarize the association of Ratzeburg Lake and Schaalsee eye, because it would have had direct access to the river Elbe over the Wakenitzrestaurant, the planning of Lübeck, however, were not realized. The construction of the Wallenstein trench between Wismar and Schwerin Lake began under Duke Albrecht VII 1531 from High Viecheln in a first section to Lostener lake, the new channel was therefore initially called Viechelner ride. More failed initially at the discord with his co-regent and brother Henry V.

In addition to the Schaale as a natural outflow originated from 1923 to 1925, following the chain of lakes from Schaalsee, Puhlsee, Pipersee and Salem Lake Schaalsee channel to about 30 meters below Küchensee, a part of the Ratzeburger to the slope of operating a hydroelectric power plant in Farchau to use. This construction project leads to a greatly reduced since the end of the Schaale. Despite the artificially created water connection to a drain on the Wakenitzrestaurant and Traveling in the Baltic Sea the Schaalsee is hydrologically counted within the catchment area of the Schaale and thus the same.

Flora and Fauna

In the upper reaches of the Schaale a lime transitional moor is crossed with rare plant species.

In the area of ​​Schaale otter, beaver and 22 species of fish, including burbot, West bullhead, loach, brook trout and brook lamprey, and river mussel shell and pea occur.

Conservation

In 1934 and 1982 have been placed under protection of the parts Schaalelaufs. The existing nature reserve since 1982 Schaaletal at Schildfeld and Vietow ( 113A ) has been enhanced by the NSG Schaalelauf ( 113B ) 1993. The NSG Schaaleniederung between Zahrensdorf and Blucher (169 ) has existed since 1990. Today's protected areas thus include the Schaalelauf from the outlet from the Schaalsee at Zarrentin to the confluence with the brews at Blücher. The field state with the Schaalelauf and the adjacent hillside forests is estimated in each case as well.
