Any pictures of it flooded? I searched and could only find pictures of it empty.

  It's probably not safe for people when flooded; it's unlikely to be a static pond, but a cascading torrent. ... but yeah, now I want to see pictures of it in use :D

  The ones we visited in Paris have 50cm thick solid steel doors and submarine hatch style wheels to wind them shut. I would anticipate that even just the air pressure that is expelled during a surge is probably enough to cause serious damage to people. On the scale of G-cans, it's hard to know if it would be more dangerous or less dangerous..
