Project summary

Edit project overview to modify the project summary.

The Lactariabeek is a small stream in a natural stream valley. The surrounding area is composed of woods and agricultural land. It has been straightened in several locations. Six packages of dead wood were introduced in the wooded part of the Lactariabeek stream. The water board performed this experiment to get more experience with dead wood after the successful Snelle Loop experiment.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Macroinvertebrate count and flow velocity were monitored. The results were not as positive as hoped because the stream fell dry.

Lessons learnt
