Therefore, they were replaced with coarser material, which did not cover the full width of the stream. This had a positive effect on macroinvertebrates and created more variation in structure.

It is an R5 category water body: slow-flowing middle/lower reach on sand. The entire Leerinkbeek is managed by water authority Rijn en IJssel. The water body is located in the province of Gelderland, municipality Berkelland. It is 8,4 km long and has a catchment of 4051 hectares. The water body consists of a single channel. The water body originates in the Hupselse Beek, near the loam pits at Zwilbrock. The Leerinkbeek discharges into the Berkel. Water levels in the Leerinkbeek are managed with six adjustable weirs. None of these weirs are passable for fish. In the Leerinkbeek water body, a single maximum water level is pursued for each managed stretch, for which the weirs are used. In dry periods, the 44 upstream stretches of the water body run dry. There are no sewage treatment plants present in the catchment of the Leerinkbeek. Five bundles were introduced over the full width of the stream. This was mainly done as an experiment with the introduction of dead wood in streams.
