If you're in Amsterdam, and have a little free time, I highly recommend the Normaal Amsterdams Peil visitor center in the City Hall.[0] There are large sight gauges, showing the water level at various points in the canal system. It gives a great sense of how far below the North Sea surface you may be.

That's nice. Devils Lake ND went with a little blue wave sign attached to the street lights to tell you how high the lake level is. It does make a person very mindful of what happens if the dike breaks.
