Luxembourg: Falling water level threatens fish

Fish mortality in the Sauer: From Monday to Tuesday, the water level of the border river between Luxembourg and Germany decreased by almost two metres. Since Tuesday, THW has been deployed in Steinheim, Luxembourg. By means of large mobile pumps, they stabilise the water level of a river arm and oxygenate the water. Clean-up operations at a barrage in Rosport (Luxembourg) caused the fall of the water level.

The two large pumps from Zell and Theley direct up to 5,000 litres of water per minute into the affected arm of the Sauer. Thus, the water level can be kept. The “spawn arm” mainly contains young fish. They threaten to be suffocated or dried up. In the night to Wednesday, THW operational staff from Friedrichsthal built a dam with the help of sandbags to prevent the further abatement of the water.

On Tuesday, Luxembourg’s civil protection “Administration des Services de Secours” (ASS) asked THW for help to be granted on a bilateral level. In the framework of the neighbour concept, THW’s regional office of Hesse/Rhineland-Palatinate/Saarland sent three THW-expert groups water damage/pumps from Zell, Theley and Friedrichsthal to the Grand Duchy of Luxembourg. It is planned to use the THW-pumps for a maximum of two days. Afterwards, they will be replaced by the pumps of a commercial provider.
