The Sack Canal , also Sack Canal , is a moat in Heringsdorf on the island of Usedom in the Vorpommern-Greifswald district . The canal, which was laid out in the first half of the 19th century, serves as a receiving water to regulate the water level of Gothensee and Thurbruch . It runs from the north shore of Gothensee over the silted up eastern Schloonsee to the Baltic Sea . The total length is about 1.6 kilometers. The Heringsdorf – Wolgaster Fähre railway line and Landesstraße 266 (formerly Bundesstraße 111 ) cross the Sack Canal over bridges.

history

In the second half of the 18th century, prompted by King Friedrich II of Prussia , extensive renovation work was carried out in the Thurbruch in order to be able to use the fen as pastureland . The result of the drainage was a lowering of the moor surface. The water level of the Gothensee had sunk by 37 cm by 1806. This greatly reduced the runoff over the Aal-Beek . During an inspection of the villages on the Thurbruch in 1811, the war council Stark found that the drainage via the Aal-Beek and the Knüppelgraben was inadequate. Instead, he suggested digging a new trench from the northern end of Gothensee to the Baltic Sea. Due to the bankruptcy of the Gothen manor , the implementation of the project was delayed. In 1817 Gothen was acquired by the forester Georg Bernhard von Bülow (1768-1854) and his brother Ernst von Bülow-Cummerow . They sold the strip of land required for the construction of the canal to the Prussian state for 5800 thalers.

The construction of the canal was carried out from 1817 to 1818 at the instigation of the Upper President of the Province of Pomerania , Johann August Sack . The canal was named after him.

Wilhelm Ferdinand Gadebusch described the canal as follows:

“The Sack Canal. 340 rods in length and 1 1/2 rods wide, is pierced through a ridge about 30 feet above the water level and provided with a lock to prevent the penetration of storm surges from the Baltic Sea. Before it flows into the latter, it leads through the small, mostly drained Schlohn Lake; its discharge into the sea, which often blows in from the sand of the dunes, often requires repair. […] The maintenance of the canal was taken over by the owner of Gothen for an annual compensation from the interested parties, around 100 thalers. amounting to. "

In 1856 Hermann Weichbrodt became the owner of Goths. In the years 1858/1859 he succeeded in draining the Gothensee with pumps that were driven by wind power or steam engines. For this purpose, the water of the lake was pumped into a ring trench, into which the Bäck was also fed as the main tributary, and channeled into the Baltic Sea via the Sack Canal. Due to high costs, also due to increasing rainfall, the complete drainage was given up again in the 1890s.

Passing the mouth of the Sack Canal on the Baltic Sea beach was dangerous in the 19th century. The travel writer CHF Koch described how a horse and cart sank into the quicksand in front of the apparently dried up canal mouth and could only be rescued with great difficulty. Similarly, Theodor Fontane describes in his novel Effi Briest the symbolically used “Schloon” as a watercourse from the “Gothener See” into the sea.

During the GDR era, the management of the Thurbruch was intensified. For this purpose, a provisional, electrically operated pumping station was built on the Sack Canal .

The state of Mecklenburg-Western Pomerania carried out extensive construction work on the canal from 1996 to 1998. In 1997 a new pumping station was put into operation. The two pumps together can deliver 2300 liters per second. The area of ​​the cut between Gothensee and the pumping station was deepened and secured with concrete elements. The outlet channel was fitted with a 190 meter long pipe with a diameter of 1.8 meters made of glass fiber reinforced plastic .
