De oude Lunterse beek

Project summary

Edit project overview to modify the project summary.

Het traject dat nu is aangepakt betreft een deel van de Lunterse beek, westelijk van Renswoude, net zuidelijk van de N224 tot aan de Liniedijk van de Grebbelinie.

Omdat de Lunterse beek een bak vol water is, met weinig stroming en dynamiek, heeft het waterschap een nevengeul gemaakt, die landschappelijk in het gebied moest worden ingericht en de beek een beter ecologisch milieu moet geven. Deze nevengeul dient tevens als overloop bij grote waterafvoeren. Omdat in de doorsnijding van de liniedijk een stuw zit in de beek, is de nevengeul via een duiker door de liniedijk gevoerd, waarna deze meanderend aansluit op de Lunterse beek na de stuw. 

De nevengeul loopt door een klein bosgebied van Klein Wolfswinkel, waar vlak langs een dassenburcht moest worden gegraven, op een van de foto’s is de kraamkamer te zien. Verder zijn er verblijfplaatsen van de vos, de havik en de buizerd en is er een reigerskolonie.

De ecologie zal verder worden gevolgd, zowel bij de oevers, waar men stobben heeft toegepast als oeverafscheiding, in de beek en ook ten aanzien van de beplanting welke langs de beek is geplaatst op een aantal plaatsen. De inrichting heeft zodanig plaats gevonden dat er weinig tot geen onderhoud aan zal plaats hoeven te vinden.

Het herstel van de Lunterse Beek is er op gericht dat het water in de beek beter gaat stromen en dat er meer variatie in plantengroei en diersoorten komt. Vissen zoals de riviergrondel en de winde kunnen binnenkort stroomopwaarts zwemmen omdat de stuw bij de Groeperkade voor vissen passeerbaar wordt gemaakt.
