The sturgeon ([ ˈʃtøɐ ], regional [ ˈstø lat ], Latinized Sturia ) is a right tributary of the Elbe in Schleswig-Holstein, influenced by tides . In terms of the type of flowing water , it is marshland .
course
The Stör rises approx. 15 km southeast of Neumünster near Willingrade in the Segeberg district . Shortly after its headwaters, it is dammed up for the paper mill, which is now a listed building .

The barrage to the paper mill
It then crosses the outskirts of Neumünster, the southern district of Rendsburg-Eckernförde and the district of Steinburg, where it flows into the Elbe about 4 km northwest of Glückstadt . In the community of Heiligenstedten it reaches the marshland; already from Itzehoe its course begins to meander. The river has a length of about 87 km and an average water flow of 21.7 m³ / s at the confluence with the Lower Elbe.
From Itzehoe (river kilometer 53) to the mouth, the Stör can be used by professional shipping, although it is becoming less important. Sport shipping, on the other hand, also uses the Stör above Itzehoe. The Stör barrage , built two kilometers above the estuary in 1975, protects the lowlands along the Stör from the effects of storm surges . The structure has two 22 m wide shipping openings with mitred gate locks.
Ebb and flow affect the water level of the sturgeon for more than half of its length from its mouth to above Kellinghusen (river kilometer 32); it is the only tributary of the Lower Elbe in which the tidal movement swings freely and the tidal limit is not defined by a transverse structure. The mean tidal range at the Stör barrage is about 2.75 meters. The tidal area from Kellinghusen to the source has a catchment area of 1,160 km². The entire catchment area covers 1,781 km².
Tributaries
Tributaries in the upper reaches are the Sünderbek , Geilenbek , Schwale (at river kilometer 8), Aalbek (river kilometer 12), Bünzau (river kilometer 18), Brokstedter Au , Kirchweddelbach (r), Bullenbach (r), Rensinger Graben (l), Quarnstädter Graben ( r), Mühlenbek (l), Bramau (river kilometer 34.8), in the middle reaches the Hörnerau (river kilometer 35), Mühlenbarbeker Au , Ihlenbek (r), Rantzau (river kilometer 42.9), Moorwetter , Lübsche Wetter , Bekau (river kilometer 60 ) and in the lower reaches Große Feldwetter (r), Wilsterau (r, river kilometer 63.5), Kampritt Wetter (r), Klosterwetter (l), Groß-Kampen-Wetter (r), Altenfelder Wetter (r), Große Wetter (l ), Neuenbrooker Wetter (l), Krempau (l, river kilometer 75.8) and the Wetter near Wewelsfleth (r). In addition, the Breitenburg Canal is connected to the Stör (river kilometer 49.5).
Fault crossings
Downstream of the town Itzehoe there are few Störquerungen: Save the Störbrücke the Federal Highway 23 are Wilster- and Krempermarsch only by the bascule bridge in Heiligenstedten that Störfähre Else in Beidenfleth and over the Störsperrwerk extending federal highway 431 connected above the Störmündung.
Former castle complexes
There were various low castles on the Stör . The oldest are Esesfeld Castle near Heiligenstedten and Wittorf Castle in Neumünster at the confluence of the Schwale, both of which date from the 9th century. In the centuries that followed, Itzehoe Castle was built in the then Störschleife in Itzehoe and the Breitenburg near today 's Breitenburg Castle. Castles were also built on the tributaries of the Stör, such as the Kaaksburg from the 9th century at the confluence of the Mühlenau and the Bekau, the Bori castle below the confluence of the Höllenau and the Bünzau or the stone castle built at the end of the 13th century Kremperau.
Legal classification
The Stör (St) is a 50.2 km long federal waterway in the area of responsibility of the Hamburg Waterways and Shipping Office from BWaStr-km 0.00 ( Rensing gauge ) to km 51.19 (confluence with the Elbe at km 678.51).
From 1882 to 1898, the Stör below Itzehoe was expanded; punctures, flattened curves and bank revetments were made. Further measures were taken from 1950 to 1954.
It is not classified as a federal inland waterway until Itzehoe (km 23.70); from Itzehoe to its mouth it is a class III inland waterway . It is one of the inland waterways on which the shipping routes regulations apply.
The sturgeon is assigned to the Elbe river basin district according to Section 7 (1) No. 6 WHG .
Construction work
Construction work not carried out
For the construction of the Eider Canal , a possible route from Kiel to the Lower Elbe , which led through the Stör was investigated in 1774 . The glacial channel from Obereider, Bothkamper , Bordesholmer and Einfelder See should be used for this. After the watershed at Einfelder See, the Lower Elbe would have been reached via the two rivers Schwale and Stör.
Realized construction measures
For several years (as of 2016) the upper reaches of the Stör has been renatured . The listed weir west of Störkathen is no longer functional and continuous. Concrete floor falls are replaced by floor slides . In the area of the municipalities of Arpsdorf , Ehndorf and Padenstedt , more than twenty new meanders were created in the straightened Stör . The renaturation has so far ended at the dammed ponds of the old paper mill east of Neumünster .
Planned construction work
Structural measures are planned in the Kellinghusen area to prevent flooding. The reopening of the filled in disturbance loop is being discussed for the inner city area of Itzehoe.
Between Kellinghusen and Sarlhusen, the sturgeon is to be renatured over a length of eleven kilometers by 2015.
Reintroduction of the sturgeon
Since 2009 attempts have been made to reintroduce the almost extinct European sturgeon . A memorial stone in the Itzeho city harbor commemorates the first exposure of 53 specimens during the Störschipper Festival.
