The Oder-Havel Canal (OHK) is a section of the federal waterway Havel-Oder waterway and extends over 54 kilometers from the Havel south of Oranienburg ( Oranienburg Havel ) to the Alten Oder ( Oderberger waters ) near Niederfinow . The Eberswalde Waterways and Shipping Office is responsible for the administration .

course

The assumed beginning of the actual Oder-Havel Canal is today's mouth of the Oranienburger Havel. It leads through the Lehnitzsee , which previously did not belong to the Havel, and reaches the Lehnitz lock . The canal continues for the most part following the earlier Malzer Canal and then replaces the older Finow Canal up to its eastern end . Its top posture extends from the upper water of the Lehnitz lock to the Niederfinow ship lift . The natural resources of the catchment areas of the Havel and the Werbelliner waters and, in the event of drought, also the Elde via the Müritz-Havel waterway are used to supply water to the vertices .

history

Today's Havel-Oder waterway is essentially the waterway from Plötzensee to Hohensaaten that was opened on June 17, 1914 under the name Großschiffahrtsweg Berlin - Stettin . At the inauguration, Kaiser Wilhelm II immediately renamed it the Hohenzollern Canal. After the Second World War , the entire length of the Hohenzollern Canal (except for its short part in West Berlin ) was renamed the Oder-Havel Canal. Today only the stretch between Havel and Niederfinow (mostly the apex of the Havel-Oder waterway) is defined as the Oder-Havel Canal. The term Großschiffahrtskanal has also been used since 1945.

The canal has the following technical features: Of the 48-kilometer-long apex section , more than 25 kilometers exist as a sealing section, where the canal water level is higher than the surrounding area. To limit any damage in the surrounding area in the event of a dam break, so-called safety gates have been installed at the Pechteich and Eberswalde . A third security gate at Lichterfelde (Schorfheide) was removed without replacement when the new Lichterfelde road bridge was built. At Eberswalde, a canal bridge built in 1910 led over the Berlin – Stettin railway line . The canal bridge was demolished in 2007 as part of the canal expansion. Previously, a tunnel had been built for the railway about 250 meters further north in the laid canal ( Neue Fahrt ). The up to 28 meters high Ragöser Damm (for a long time the world's highest canal dam, still one of the highest today) crosses the Ragöser Fließ , the water of which flows through a passage in the dam. 1927-1934 was to replace the lock staircase Niederfinow the ship lift Niederfinow built with a lifting height of 36 meters (the construction of the world's largest mastered by an elevator height difference). The lock staircase remained in operation parallel to the elevator until 1972. In the winter of 2006/2007, the preparatory work for the construction of a new ship lift to the north of the existing one began. The foundation stone was laid in 2009, and commissioning is scheduled for 2025 at the latest.

As part of the expansion of the waterway, the canal will be widened from 34 m to 55 m and the water depth will be increased from 2.8 m to 3 m or 4 m. The expansion of the entire Havel-Oder waterway is part of the 2003 Federal Transport Infrastructure Plan and costs a total of € 600 million. In the future, ships up to 110 m in length and 11.40 m in width should be able to operate here. In the case of pushed convoys , the limit will be 135 m after the expansion.
