The Floßgraben is a 22 km long tributary of the Upper Havel , into which it flows in the Woblitzsee .

course

The watercourse of the raft ditch begins at a small target , at 87.5 m above sea level. NHN located between the Carpiner See in the catchment area of the nuns Bach to Tollense and the Grünower lake during the Havel inflow Godendorfer Mühlebach-Hegen stone flow . Complemented by tributaries from other Söllen, after 3.3 km it reaches a narrow but 800 m long nameless lake and after another 0.6 km the Schweingartensee . It leaves it at the southern end and reaches through a two-kilometer long valley with several small ponds, the Pöhlen , the Lutowsee , where the mouth and outflow lie at the northern end at Herzwolde. On the following 1.7 kilometers of water to the Großer Fürstenseer See, it flows through the Kleiner and Großer Schmarssee. Between the Großer Fürtenseer See and the Tiefen Trebbower See , the body of water is developed as a canal. From there to the Woblitzsee there is a river that crosses the largely silted up flat Trebbower See .

history

The eponymous middle course of the raft ditch from the Großer Fürstenseer See to the Tiefen Trebbower See was only created around 1930 and put into operation in 1932. The lower course of the raft ditch was previously the lower course of the Stendlitz . The upper course consists at least partially of artificial ditch connections between lakes previously only connected by groundwater, which were created from the Middle Ages to the 19th century to provide water mills with the necessary inflow and outflow. The oldest of the watermills was the Domjüchmühle on Domjüchsee . In order to improve their water supply, water from the Großer Fürstenseer See was fed to the Jägerpohl of the Stendlitz through the Zwirnsee and the two sheep farms . Since this flowed from the Domjüchmühle to (Alt-) Strelitz (actually still flows, only the mills no longer exist), the water also benefited the town mill there. Some of the water in the Großer Fürstenseer See came from the Lutowsee . The youngest and uppermost mill was located at the outflow of the Schweingartensee, whose water supply was also improved by artificial ditches. It was first recorded in 1780. Since its first operator was a protective Jew , it was also called the “Jewish mill”. After this mill, the water was directed to the Lutowsee.

By 1930 the water mills, which had only limited capacity on the poorly sloping waters, had been replaced by machine-driven mills, but timber rafting was still just important. In this situation sixty year old plans were taken up again and the Great Fürstenseer See was connected to the Tiefen Trebbower See by a canal suitable for the Holztrift .

As a result, the current between the Grosser Fürstenseer See and Jägerpohl turned around over time. This connection was completely interrupted during the GDR era.
