The Störsperre is a barrage at the mouth of the Stör in the Elbe in the municipality of Wewelsfleth. The barrage was built from 1971 to 1975 as a result of the storm surge of 1962 to protect against storm surges. For this purpose, a new estuary was dug north of the old one. (Source: Wikipedia)
The Stör Barrage is a major structure at the mouth of the Stör into the Elbe, located in the municipality of Wewelsfleth. Built between 1971 and 1975 in response to the devastating storm surge of 1962, it serves to protect the inland from flooding and storm surges. The barrage controls the water level of the Stör and prevents floodwater from the Elbe from reaching land. For this purpose, a new estuary of the Stör was created north of the old course, while the original river course is now used as a port.
