Wilsterau
The Wilsterau at its mouth in Stördorf, where it is connected via the lock Kasenort with the sturgeon (looking upstream )
The Wilsterau (also Wilster Au) is a north-western (right ) side of the river sturgeon in the Steinburg district or in the Wilstermarsch.
Course
The construction of the North Sea-Baltic Canal from 1887 to 1895 was the Wilsterau from their natural source drive, which lay west of the channel near Castle ( Dithmar ), truncated. It begins today east of the channel, to which it is connected via a pumping station, and thence in a southeasterly direction making a bow in a southerly direction, and then reaches Rumfleth and Wilster. By Wilster the Wilsterau was originally in a loop, but this was abbreviated with a puncture. Near Kasenort it opens at river kilometer 63.5 in the sturgeon. The present development has a length of about 19 kilometers.
Water Resources
Since the construction of the North Sea-Baltic Canal, the Wilsterau has no natural source more. Even with the Holstenau, one of its former tributaries, it is only connected to Moorkanal and the pumping station on the Kiel Canal. It therefore has no relevant natural inflows more, but is fed mainly on pumping stations. Its catchment area covers approximately 3,500 hectares today only. Since the construction of the Nord - Ostsee-Kanal they verschlickt increasingly by the lack of natural flow rate and thus the lack of rinsing.
Fish fauna
The Wilsterau eV is managed by the ASV " Petri Heil" Wilster. The lake has a large stock of pike and perch, whitefish dominate among the bream and ide, which migrate to the spawning of sturgeon and the Kiel Canal in the lily fields and weedy areas of the tide flows, where they can reach trophy weights. The river is one of the best fried fish waters in northern Germany.
