The Knüppelgraben , also Knüppelscher Hauptgraben , is a drainage ditch in the Thurbruch on the island of Usedom . It is named after its builder, the Prussian master builder Knüppel. The Knüppelgraben begins east of the Kachliner See and initially runs in a south-easterly, then in a northerly direction in an arc through the southern Thurbruch. It runs through the municipal areas of Dargen , Zirchow and Korswandt in the Vorpommern-Greifswald district .
history
In the 18th century, Prussia tried very hard to gain additional pastureland by draining bog areas . In 1750, Friedrich II commissioned the master builder Knüppel to examine how the Thurbruch could be drained. Knüppel was apparently based on an older trench project that the Prussian surveyor Martin Friedrich Schwatcke had drawn in his map of the Thurbruch in 1738. The original planning probably goes back to the Pudagla governor Glüer, who in addition to the straightening of the Bäck , the natural watercourse from the Kachliner See to the Gothensee , planned an additional channel between the two lakes.
Under Knüppel's direction, a seven-kilometer-long and four-meter-wide “Neuer Graben” was dug, the course of which follows the southern and eastern edge of the moor. The headland on which the Ulrichshorst bog colony was later built was bypassed by a western arch. At Korswandt the ditch was connected to the Wolgastsee . The water of the Kachliner See and thus the Thurbruch was diverted over the Wolgastsee through the Zerninsee and the Swinemoor to the Stettiner Haff .
Despite various trench clearance orders and service obligations of the local farmers, the maintenance of the trench turned out to be problematic. In 1772, during the large-scale artificial drainage of the Thurbruch carried out under Franz Balthasar Schönberg von Brenkenhoff , the heavily weed trench had to be cleared. In the Thurbruch ditches were dug to the two lakes and to the Knüppelgraben. At the same time it was connected to the Gothensee via the newly built fire ditch . The further discharge now took place from there via the Beek into the Baltic Sea . Towards the end of the 18th century, the Knüppelgraben and the Beek had to be weeded and cleaned at a cost of 600 thalers.
Around 1860, at great expense, it was possible to drain the Gothensee via the Sack Canal, which was created in 1819 . Like the Bäck, the water from the Knüppelgraben was also channeled on a 1.5 km long dam over the bottom of the lake into a ring trench and from there to the Sack Canal. The drainage of the Gothensee was later abandoned because of the high costs.
In 1920, a wind pumping station was set up directly at Knüppelgraben near Lake Kachlin . Between 1957 and 1969 the Thurbruch was extensively meliorated . The Knüppelgraben was included in the new trench system, but partially replaced by other trenches in the area around Korswandt and Ulrichshorst.
