The Sacrow-Paretz Canal north of Töplitz near Potsdam

The Sacrow-Paretzer Canal (SPK) in the state of Brandenburg is a section of the federal waterway Untere Havel-Wasserstraße (official abbreviation: UHW). The Brandenburg Waterways and Shipping Office is responsible for the administration .

location

The canal begins at km 20.11 of the UHW and connects the Havel at the city limits of Berlin - Potsdam ( Jungfernsee ) with the Havel east of Ketzin / Havel . At km 32.59 the canal ends at the Göttinsee near Paretz and there it reaches the Havel again. Shortly before that, the Havel Canal joins the Sacrow-Paretz Canal from the northeast . The Sacrow-Paretz Canal crosses the White Lake , the Fahrlander Lake on the southern edge and the Schlänitzsee ; the Schlänitzsee belongs to the river area of ​​the Wublitz . At km 28.48 south of the village of Uetz , the federal motorway A10 - Westlicher Berliner Ring crosses the canal. A total of four bridge structures cross the Sacrow-Paretz Canal. The entire waterway is 12.5 km long, around 7.5 km of which are canals and the remaining 5.0 km of existing lakes.

Hydrology

Since the canal has no locks, at least half, but often a much larger part of the Havel water flows from Jungfernsee to Göttinsee through the canal and accordingly less through the Potsdam Havel bend with old and new voyages.

Flows	Havel: Spandau- Jungfernsee	difference	Canal: Jungfernsee- Schlänitzsee		Canal: Schlänitzsee- Göttinsee	difference	Havel: Göttinsee- Ketzin
Medium flood	107 m³ / s	37.1 m³ / s	72.9 m³ / s		74.6 m³ / s	60.4 m³ / s	135 m³ / s
Mean water	35.1 m³ / s	6.5 m³ / s	28.6 m³ / s		32.4 m³ / s	18.3 m³ / s	50.7 m³ / s
Medium low water	6.33 m³ / s	3.13 m³ / s	3.20 m³ / s		3.00 m³ / s	0.47 m³ / s	3.47 m³ / s

Explanation for the local differences in the water flow in the canal: Part of the water here takes its way through the lower Wublitz . On the other hand, there are also lateral tributaries.

The jumps in the flow values ​​compared to the Spandau - Jungfernsee and Götinsee - Ketzin - Brandenburg sections give an indication of the parallel flow through the Potsdam Havel. The deficit of the flows between Ketzin-, Brandenburg and Plaue compared to Spandau-Potsdam at low water is explained by the particularly large extraction of service water during drought and by the considerable evaporation of the large Havel lakes at high temperatures.

history

At the beginning of the 1870s, extensive concepts were developed to improve shipping conditions on the waterways between Berlin and the Elbe . The first implementation was the construction of the Sacrow-Paretz Canal. Work began in 1874. As early as 1876, shipping was able to operate directly between Sacrow and Paretz . As early as 1888–1890 the sole was widened to 18 m and deepened. In the 1920s it was widened. Since then it has had an average water level of 50 meters and is around 3.40 meters deep.

Main reasons for construction

The main reasons were:

• bypassing the difficult bridges in Potsdam and Werder (Havel) ;
• the shortening of the route on the waterway by 13.5 km;
• avoiding the trip over the Schwielowsee , which at that time was dangerous for shipping , especially when the wind was strong from the west.

development

The Sacrow-Paretz Canal is one of the waterways that are being expanded for larger inland waterways as part of the German Unity Transport Project No. 17 . The expansion was planned from 2008 and should take four to five years. The canal expansion originally included a widening by excavating the northern bank. At the same time, a deepening of more than four meters should be made. Except for the narrowing at the Nedlitz piercing, large ships should be able to meet along the entire length of the canal. Since the canal is partly still in an undeveloped state, a traffic regulation was introduced. This includes a stipulation of meeting and overtaking bans as well as passing points for certain traffic groups. In the region there were and are protests against the expansion, since, especially in connection with the regional effects of global climate change, far-reaching consequences for flora, fauna and water balance are to be expected. Because of unforeseeable ecological consequences, the city of Potsdam has also rejected the canal expansion in a statement (among other things because of a forecast lowering of the water level of the Jungfernsee by two to nine centimeters). Studies commissioned at the beginning of the 1990s into an increase in cargo ship traffic have not yet been confirmed. In autumn 2008, the city of Potsdam and environmental associations filed a lawsuit against the canal widening at the Federal Administrative Court in Leipzig. In this regard, a settlement was reached in January 2010 in which the canal will be deepened, the banks re-paved, the canal bottom smoothed, but not widened. After completing the environmentally relevant tests as part of the planning approval procedure, careful expansion began. Beaver castles have been implemented and protection zones for sand lizards have been established. In the area of ​​an already relocated beaver castle, new beavers have settled.

annotation

With the construction of the Nedlitzer Durchstich section of the Sacrow-Paretz Canal from 1902 to 1904, the first bridge was built along the road over the new piercing between the White Lake and the Jungfernsee. The penetration was widened in 1932/33 and the bridge was also renewed in the course of the expansion. Destroyed at the end of the war in 1945, a new steel truss bridge was built in 1950 from the rubble of other bridges, which was called the Bridge of Peace . Over the years, the bridge became increasingly dilapidated, also as a result of intensive use by the heavy military vehicles of the Soviet army barracked nearby until the beginning of the 1990s. In 2010, construction work began on a new Nedlitz south bridge, which has been open to traffic since late 2011. On the post-war bridge there was a metal sign that read 1950 and Bridge of Peace . This plaque was lost for about a year and was put up again on January 23, 2013 in the presence of the Potsdam Lord Mayor on the south bank.

Traffic control

The control section 14 was defined in the section band of the Sacrow-Paretz Canal. It begins at kilometer 20 of the Lower Havel waterway (UHW) and ends at kilometer 27. In this section of the waterway, traffic is directed according to appropriate traffic groups .
