Ulm (km 2593)

Highest-located ESB sampling site for breams in the river Danube

Ulm is the only sampling site in the sub-area Oberhalb Illermündung. It is located in the immediate vicinity of the industrial area Danube Valley and extends from the barrage Ersingen to the barrage Wiblingen (upstream of stream kilometre 2590). The sampling site covers the main stream and several barrages as well as oxbows that are designated nature reserves. Motorized boats are not allowed in the entire area.

Bream are caught in one of the oxbows whereas zebra mussels are exposed upstream the barrage.

At the sampling site Ulm the water status of the Danube headwaters is assessed. Ulm is the highest ESB sampling site of the Danube which allows sampling of bream.

The monitoring site Ulm-Wiblingen of the State Office for Environment, Measurements and Nature Conservation Baden-Wuerttemberg (LUBW) is located immediately downstream of the ESB sampling site. This allows the comparison of the ESB data with the physical and chemical water data of the federal state’s monitoring network.
