Since the early Middle Ages drainage deteriorated through a rise in the Maas river-bed, building of watermills along the streams, lack of upkeep of channels and intentional military interference with outflow, Bois le Duc derived its impregnability as a frontier fortress from nearly permanent inundations.
Impact on agricultural development was disastrous. The turning-point was reached in 1813 when the region achieved its present political status, though substantial improvements started only after the institution of river authorities around the 1860's. Discharge was still poor and agriculture was still suffering.
