"You’re welcome. So. What you want to see is the two big diversions. We blew holes in the levee. One on the left bank at Wills Point, just about thirty miles down from here, the other in the right bank another, oh, five miles farther along. Fresh water’s pouring through, dumping silt where it hits the Gulf, and the silt’s making new land—taking back some of what the Gulf stole from us. But the water isn’t clean—remember where it all came from." Here Margaret swept her arm around in an arc directed generally northward, as if to encompass the whole watershed of the Missouri-Mississippi-Ohio system, all the way to Canada. "And because it’s fresh, it kills the saltwater ecosystem. All those homeless people you saw on your way in? Many of them were working oystermen ten years ago."
