Project summary

Edit project overview to modify the project summary.

The Raam region originally featured many small moors and bogs, connected by natural stream valleys. When the area was exploited for its peat, several waterways were dug to ensure sufficient drainage for peat extraction. The upper stretch of the Lage Raam is one of these waterways. This artificial channel was connected to the natural lower stretch of the Lage Raam. This water body is classified as a freshwater buffered ditch (M1a). The dug-out Lage Raam receives water from the Tovensche Beek and Ledeackerse Beek and discharges into the (natural) Lage Raam.
