Most notably, the developing vegetation caused the water to smell when water levels were high, so that weeds had to be cut along the entire stream. 52.66659,6.30536 Sander Waterschap Drents Overijsselse Delta Verheijen ,, ,,, Extensive groundwater monitoring shows that the upstream groundwater level is rising, which was the intended effect of the measures taken. Locally, the stream is becoming significantly narrower due to vegetation growth in the treated areas. The measures have not been in effect long enough to draw conclusions about the effect on macroinvertebrates and fish. 26182 In progress The Reest is a slow-flowing stream on a peat substrate that meanders over its full length, which is quite uncommon for Dutch streams. Stream restoration measures in the Reest aim to restore the hydrological conditions in the stream valley. The goal is to decrease the drainage capacity of the stream, leading to higher minimum groundwater levels in summer and increased seepage into the valley. This is supposed to improve the ecological potential for aquatic plants, invertebrates and fish. The surrounding valley should become better suited to support wet grassland. To this end, three 50-meter-long stretches have been lined with dead tree stubs. In addition, sand was deposited in the stream, raising the streambed by 50 cm. Finally, several barriers were created from tree trunks and rocks.
