"The drawdown is something that would occur naturally and even in this altered state out here, when you draw it down , it has natural process of germinating certain plants that are desirable for fall feed for fall migrants for waterfowl.  And if you don't draw that down you don't germinate it, and if you don't germinate it, there's very little fall feed in that marsh for the migrating waterfowl.  So it's an extreme benefit for fall migrants.  And when the draw down occurs, there's a advertament boom and so they're going to utilize it, so there's a whole process there that occurs naturally and that's basically what they're trying to duplicate.  So in a way, that natural process is being repeated on an annual basis, and that's what they're used to, so it's just a benefit for both spring and fall migrants."
