The Dahme (from Seddinsee to the Spree until 1938 also Wendische Spree ) is an approximately 95 kilometers long tributary of the Spree , which flows southeast of Berlin in the state of Brandenburg and in Berlin. She is eponymous for the Dahmeland .

The Dahme rises southeast of the small town of the same name Dahme , touches or flows in a northerly direction the smaller cities Golßen , Märkisch Buchholz and King Wusterhausen and ends in Berlin Koepenick just behind the castle island in the River Spree. About 26 kilometers between Prieros and the bridge in Schmöckwitz is the Dahme Federal Waterway under the name Dahme-Wasserstraße (DaWanda). At Schmöckwitz the waterway ends at the Spree-Oder-Wasserstraße (SOW) at km 44, the 11 km long section of which is the Dahme to Berlin-Köpenick.

The name Dahme is possibly derived from the Slavic term Dembrowa = 'oak forest'. Other authors attribute the river name to an older name from the Germanic pre-population, which may denote a dark river. Such old names were often passed on from the remaining Germanic population to the Slavic settlers.

Course, nature park and flood canal

Dahmequelle

The Dahme near Rietzneuendorf

The river rises south of the Brandenburg town of Dahme and first runs its course to the east. Here the Dahmetal, together with the valley of the Schweinitzer Fließ south of the headwaters, forms the natural border between the Fläming and the Lausitzer Grenzwall . At the same time, the Dahmelauf between Liebsdorf and Falkenhain forms the eastern border of the Niederlausitzer Landücken Nature Park . At Golßen the river reaches the Glogau-Baruther glacial valley , which it crosses and leaves again towards the north at the village of Staakow (here it enters the Dahme-Heideseen Nature Park ). Between Golßen, Rietzneuendorf and Briesen , the Dahme meanders to Märkisch Buchholz as a small, largely natural river further north. It flows through swampy alder forests on the western edge of the lower Spreewald , from the village of Teurow to its mouth in Berlin, the river follows several glacial channels .

In Märkisch Buchholz, water is supplied to the Dahme from the Spree via the Dahme Umflutkanal . Originally the Spreewald was supposed to be better protected from floods. From here the Dahme flows in a wide, partly canal-like river bed and is navigable for the remaining 51 km up to the confluence with the Spree.

From Prieros it widens into a chain of lakes , similar to the Havel in the Berlin- Potsdam area. Via Dolgenbrodt , Gussow , Bindow , the Krüpelsee , Königs Wusterhausen , Zeuthen and the Zeuthener See , Eichwalde and the Langen See , the Dahme reaches Berlin-Köpenick and returns the “borrowed” water to the Spree. On the 480 meter long section between the Krimnicksee and the historic Neue Mühle lock in Königs Wusterhausen, the Dahme bears the name Staabe . A short right arm of the Dahme, which encloses the Köpenick Castle Island with it , is known as the Frauentog . The name comes from the laundresses who used to work here.

Fontane and the Dahme

As part of his wanderings through the Mark Brandenburg , Theodor Fontane undertook a boat expedition on board the Sphinx in the middle of the 19th century with the aim of penetrating "as far as the lake and source areas of the 'Wendish Spree'". The very idea of this expedition caused Fontane "to be excited, as if it were an advance as far as the lake and headwaters of the Nile".

Fontane left the following characterization of the river:

“At the bridge to Cöpenick, two rivers meet almost at right angles: the“ real ”Spree and the“ Wendish ”Spree, the latter also known as“ the Dahme ”. The Wendish Spree, even more than the actual one, forms a large number of magnificent lake areas that are connected by a thin thread of water. Navigating this river is a contradiction in terms, and while haw-like latitudes have just been passed on which a sea battle could be fought, a quarter of an hour later the boat pushes its way through such narrow defiles that the oar poles touch the banks to the right and left . And like the width, the depth also changes. At one point, earth funnel and crater where the plumb line fails, and right next to it there are ponds and ponds where even the flattest boat travels through the swamp bottom. So this waterway. "

At Prieros, Fontane and his traveling companions no longer drove up Dahm, but followed the chain of lakes, which is now called Teupitz waters . After a total of two days of travel, they reached the end of the navigable waters near Teupitz .

Jacza von Köpenick

Although the Dahme did not have the historical significance of the Nuthe with its Nutheburgen , it still played a role in the founding of the Mark Brandenburg . On today's Schlossinsel in Berlin-Köpenick at the confluence of the Dahme and Spree rivers , there was a Slavic castle for a long time , which was destroyed and rebuilt several times. In the middle of the 12th century this castle was a center of power for the Sprewanen tribe under their prince Jacza von Köpenick . Jacza offered Albrecht the Bear , the founder of the Mark Brandenburg, considerable resistance and was not decisively defeated until June 11, 1157, the day the Mark was founded.

Measures against the extinction of species

In order to preserve the eel population , glass eels caught in the sea are released .
