Project summary

Edit project overview to modify the project summary.

De Lactariabeek ontspringt in Limburg. Deze beek ligt in een natuurlijk beekdal. De beek is daarom getypeerd als (R4) langzaam stromende bovenloop op zand. De beek is op veel plaatsen sterk genormaliseerd en vergraven. Toch heeft de beek hier en daar nog steeds een natuurlijk verloop. Op de Brabants-Limburgse grens kruist de beek het Afwateringskanaal met een sifon. De beek loopt deels door een bosgebied, waar de beek in de zomermaanden kan droogvallen. Vervolgens stroomt hij door een gebied met overwegend landbouw.
