I beleive you are right with the Pressure between that the fish bite the best right around 30.0. We were in southern iowa on sunday and in the morning the pressure was right at 30 and the fish were bitting like crazy, late morning it started dropping pretty fast and they started to really slow up. Big Ron are you the fellow that is always fishing the brush piles in the summer in the middle lake with waders? Any body been brave enough to take a 4 wheeler down to lanesville and try to get on the crappie yet?
The middle lake not the south lake. The middle lake is on your right hand side as you are coming into Sabula across the causeway from the bait shop. (by Driscoll's island) Lanesville is the slought that takes you up to Browns lake!!! Usually hear people doing real good up there. but it is one hell of a walk if you don't have a quad.
