The Schwinge (Sw) is a 28.7 kilometer long, left-hand tributary of the Elbe in Lower Saxony . It rises in the Hohen Moor near Mulsum on the Stader Geest in the bifurcation area with the Oste . From here it flows in a largely natural, more than 20 km long upper course to the Hanseatic city of Stade . The delightful floodplain of the upper reaches and the Stader Schwingewiesen are under landscape protection because of their very natural river landscape and their biodiversity .
The approx. 1000 year old Hanseatic port on the Schwinge is located in Stade . Since 1792 the upper course has been separated from the tidal flow by the sluice at the Salztor lock ; the lower reaches of the Schwinge begins, which flows into the Lower Elbe at Stadersand northeast of Stade at Elbe kilometer 654.8 . The mean tidal range of the lower reaches increased to 3.30 meters due to the deepening of the Elbe , while the level fluctuations in the upper reaches due to the backwater when the gates are closed are only a few decimeters . Despite the dyke , the banks of the lower reaches are lined with narrow strips of extremely rare freshwater tidal flats.
From the Elbe to the Salztorschleuse in Stade, the Schwinge is a 4.6 kilometer long federal waterway , for the first 700 meters to the saline loading point of class IV , from then on class II. The shipping route regulations apply on it, and that is responsible Hamburg Waterways and Shipping Office . All the places on the Schwinge have been better protected against floods from storm surges since the swing barriers near the mouth of the river were completed in 1971. The 16 m wide opening is closed by two mitred gates .
From the late Middle Ages until the 1950s, the swing arm was used by Ewer to transport goods. When the Schwinge and the Hanseatic port were excavated, countless historical finds were recovered, including the famous inscription swords with the name Ulfberht from the 8th to 12th centuries. Today, on the other hand, the leisure and sport boat traffic dominates the shipping on the lower reaches, above Stade the Schwinge is not navigable.
