I've fished some exceptional ponds in the DeMotte area, and great feeder ditches around there too...ever fish the Iroquois?
I have been spending most my time at Willow Slough, Lake george, and a lil bit at Flint over by you in Valpo
Lake George in Hammond, or Hobart? I've taken a 6.5 pounder out of the one in Hobart, but...the one in Hammond is near Wolf Lake where the bass, pike, musky and walleye fishing is exceptional!
Flint is exceptional too...try Maxinkuckee for some great smallies some time.
