Hey I’m close to Iowa.
My best luck this time of year has been fishing areas in 6 feet of water or less. Also try to fish places where you can see fish of any species or birds.
Bait and rigs should be instant and simply. For example hair rig with corn/fake corn and a Panko pack.
Fish a spot for an hour tops then move.
Fish the warmer parts of the day.
Dont let a blank shake your confidence.
I don’t have experience with the zig but I hope to change that this year and do some more float fishing.
I got my first fish of the year yesterday....
