Guess it depends on how much building they had to do to make the swamp. I don't think they dropped well over even 50 feet of dirt in the thing. No way 100 or so feet of sediment happened along there naturally either in just a few hundred or so years...... My assumption all along has been it was a shallow harbor kind of area and they just dammed up the opening.
I have 10 years of experience working a sand mine. I've seen 10 feet of sediment buildup in a week. Figuring out what happens when you are changing the ground underneath us....science can't even figure it out. It does whatever it's gonna do.
