I just returned from north central SD and the hunting was great.  Tons of birds around and more roosters than I normally see.  The only water was in the low areas that should have water anyways, I wore my hiking boots all week and never got my feet wet (I had 4 pairs of boots and many socks because of all the reports but never needed the extras).  It was a very good trip with limits coming early most days and I can't wait till I get back out there for late season.
