Thanks for that great info.Now I'm really confused on where to fish.All we can go by is what we see at the surface.So if too muddy to see your lure more than a few inches we move on.You say may be cleaner water down and catchable fish there.I know the walleye like the cloudy days.I wonder if the fish find some muddy water near surface to cut down the light and feed in cleaner water under it.I asked Pooh bear about locations to fish and he said could not catch anything in the clean water last month?Interesting.
