In order to facilitate local biodiversity, a gravel nourishment was performed. The nourishment recreated a relatively shallow, permanently flowing habitat with well-oxygenated sediments, facilitating the establishment of numerous macro-invertebrates, fish, and aquatic macrophytes.

In total, the project involved the nourishment of 40,000 m³ of local gravel excavated from a side channel that had been constructed recently. The nourishment took place in 2025. It was carried out as a measure as part of the Natura 2000 area Grensmaas and the WFD goals for the same river.
