Trust me on the fact that Iowa will have better fishing in April than Missouri. I have fished Red Rock And Rathbun several times, and my brother(An Iowan State Trooper) is saying that when the cottonwoods bloom it will be phenom conditions. I am probably going to go catch those fish first of May myself. Save your gas money and work the lakes close to home.
Maybe I will see ya.
I used to fish alot of lakes in Iowa. Big creek and Saylorville, as well as up north in spirit and Okiboji. Pine is fine and when it comes to rivers the des moines is the best.
Closer to you might be a series of lakes in the chariton area. I forget thier names, but I think the chariton river is the source.
Look at my blog and you will see all the fish we catch in Iowa.
