Last sampling site in the dammed Rhine before the German-French border

The sampling site Iffezheim is located in the head- and the tailwater of the barrage Iffezheim. In this section the Rhine is straightened and coarse stones support the river banks and the areas around the barrage. Footpaths line the riverbanks. On the French site of the tailwater a marina borders the sampling site. The adjacent areas are mainly used for agriculture. No above-ground discharges are present in this river section.

This sampling site is used for determining the pollutant load of the Upper Rhine upstream of Iffezheim. Samples are taken from bream, zebra mussels, and suspended particulate matter.
