BW

The Wester ( called the upper reaches Wäster ) is a left or southern, 8 km long tributary of the Möhne in North Rhine -Westphalia, Germany.

Documented the waters name appears in 1471 as " Westerbroke " - Wester- break (certificates pin Meschede, No. 363 ).

Course

It arises in the Arnsberg Forest Nature Park around 2 km south of the center of Warstein to 343 m above sea level. NN by the confluence of the coming of southeastern Long Bach and the south-west direction from coming Wideybachs. From there it flows as Wäster north through Warstein and reaches as Wester Belecke to there open to 252 m altitude in the Mohne.

Special

The Wester cuts through the two Warsteiner Massenkalkzüge. Depending on the groundwater level in the karst aquifer, therefore, the upper reaches of the Westerschelde completely disappear underground, drop the dry creek bed. Later in the Wester is fed by numerous karst springs, which some sources are taken as sources of drinking water. In addition to the combined sources, there are numerous tributaries from the underground in the stream bed itself The inflowing karst groundwater is always well above 5 ° C, the water of the pond Buller source even about 15 ° C warm. This strong inflow of relatively warm karst groundwater from deeper layers of the Wester is never frozen in the field of Warstein.

This feature is already in the early modern historian Hermann Hamelmann - mentions in his book " Simplex et brevis Delineatio Urbium et Oppidorum Westfaliae " (1526 1595): " Wastena, Wasten: A city near the Ruhr, it has the peculiarity that there water is found, which is cold in summer and warm in winter. "

The ever- flowing water meant in the early industry a great location advantage, since the waterpower was available throughout the year, there was no failure by frost in winter. Numerous mills and hammer mills have taken advantage of every inch of the slope. In urban Warstein lists the Topographic Map of 1837 to about 700 m river two mills, a paper mill, a sawmill and a copper hammer. The height difference is on these 700 m, 10 m. When the Warsteiner ironworks was licensed in 1739, she could no longer rely on hydropower Westerplatte in this area, they had to rely on the small right-hand tributary of the Treise.
