Ironically, I can't say I support this. I've lived in California, where the core of Engineer's hammered the Colorado river straight (as they say). The cement lined aqueducts drain the river and divert the water into Los Angeles, San Diego, and Southern California. Today, the Colorado river doesn't even make it to the ocean, but drys to a mud puddle in some urban barrio in Mexico.
Sure it's not the same thing, but still... Paying "that" kind of money to fix a problem by us "mucking" with nature, leaves me believing, maybe we should have never messed with it to begin with.
Either that, or reroute the river to N.C. and we will use the sediment to fill in the area between the coast, and the outer banks. I get a free lot for thinking of it!
Wonder what Mark Twain would say?
