Secret of Man and Horse By Willy Kruijssen and Christel van Vliet at Polder Blokhoven near Schalkwijk

In the early days, there was little control over the depth and extent of the inundations. With the construction of the New Dutch Waterline, inundations were much more manageable. Nowadays, some of the inundation fields are used as water storage areas for flooding during heavy rainfall. One such example is Polder Blokhoven, near Schalkwijk.
