The Lucie Canal is an artificially created, year-round water-bearing river in the Lüchow-Dannenberg district in Lower Saxony .
course
The Lucie Canal today has its origins in Saxony-Anhalt as a trench in a swamp area of the southern Gartower fir , which it drains. Immediately to the east of the headwaters lies the Harper Moor nature reserve , and to the south lies the Arendsee . The trench leads over five kilometers in an initially westerly direction to the state border with Lower Saxony . From there it is called Luciekanal . At the national border, it enters the Planken and Schletauer Post nature reserve , a swampy swamp forest area that belongs to the Elbhöhen-Wendland nature reserve . After about four kilometers, the body of water leaves the forest area in a westerly direction, between the villages of Schletau and Lomitz , which are roughly the same distance .
On the following 14 km of its north-westerly course, the Lucie Canal flows almost dead straight through agricultural areas, far from nature, and fed by numerous land and drainage ditches. At Thurau , to the north, it passes a landmark that can be seen from afar , the former reconnaissance tower of telecommunications sector B from the Cold War era . The federal highway 493 crosses it southwest of Klein Breese , then it passes the former overseas radio reception center Lüchow, which is a little to the left, and then picks up the Königshorster Canal from the left via a pumping station .
There, the direction of flow swings between Tarmitz and Künsch to the north and the canal then continues through open cultural landscapes towards the eponymous forest area Die Lucie . At the southern edge of the forest area, the Lucie Canal joins the Jeetzel from the right north of Seerau .
history
The Lucie Canal was laid out in the 18th century. According to the available maps from 1906, the highest point of the canals connected to the Lucie Canal at that time lies along the trench north of Ziemendorf in what is now Saxony-Anhalt in the Ziemendorfer Heide location at a height of 28 m. On its 32 km long way to the Jeetzel, it takes in numerous tributaries from drainage ditches. By the end of the 1950s, the Lucie Canal flowed into the Jeetzel at Groß Heide and Soven . Since the Jeetzel was regularly influenced by the floods of the Elbe, it was led into a new bed and diked in from the mid-1950s in order to prevent the flooding associated with the backwater. Since then, Jeetzel has been using the bed of the Lucie Canal from Seerau . At the former estuary near Soven, the Alte Jeetzel now crosses the Jeetzel in a culvert built in 1965 . The Lucie Canal was diked around 1962 for the last six km up to the confluence with the "new" Jeetzel. Because of their importance, these dams were reinforced after 2009 and provided with concreted dyke defense paths.

Purpose and hydrogeology
The Lucie Canal is navigable in sections with small craft with a draft of less than 50 cm , but only seasonally for larger unloading depths. The economic purpose of the Lucie Canal, however, is primarily the surface drainage of approx. 180 km² of agricultural land, which without it could only have been used for peat cutting or forestry. The hydrogeological structure is characterized by the groundwater runoff down to the Elbe valley, which, however, partly sinks into salt domes.
Flora and fauna
The ecological condition of the Lucie Canal is considered unsatisfactory in the upper reaches. The upper course to the Lomitz-Schletau road (km 8 on the map) regularly falls dry in summer. Although the Lucie Canal with its 46 clans is one of the most species-rich waters of the Jeetzel tributaries, the locations close to the banks are dominated by various small spawning herbs. The water in the profile, which is sealed on both sides, is clear and there is only a weak layer of mud on the sand sole, which could provide a suitable habitat for macrophytes . Downstream, the conditions of the Florence improve noticeably, but do not reach the growth diversity of a free-flowing body of water. The fish stocks correspond to those of the lower Elbe and can be fished in sections. The beaver has not become at home due to the lack of wood on the banks. Occasionally some migratory and breeding birds stop by the water.
Despite its limited importance in the biotope network, it was included in the Natura 2000 FFH area of the Jeetzel water system with spring forests in 2004 .
