| Since 1291 the Hollande IJssel isn't a
streaming river anymore. The reason is that the Hollandsche IJssel ,then a side river
of the Lek, was dammed. In that way the area around the Hollandsche Ijssel didn't have so
much troubles because of the floods they caused. There were so much floods because the
river had to cope with so much water, because the other rivers in that area were not so
deep anymore because of the sand that was transed by the river itself. When the armies of Napoleon occupied The Netherlands, A. Blanken Jzn.
had a plan. He wanted to build a dam between Krimpen and Capelle, on the same spot the
Deltaworks are now built. This dam had three slides. These ideas came after a flood in
1808, on january 15. 150 years later, in 1953 the same thing happened again. The design of
1953 is technically more advanced, afcourse...
