Monroe is a big lake, and you have to fish it alot to learn where the big ones hang out. You will catch a TON of 9the inch fish and smaller. A TON!! if you want a wall hanger Monroe definitely has them on it.
Cataract is a great lake to fish also. I haven't fished Cataract as much as some of the guys on here but it does have alot of quality fish in it. Both are great and beautiful lakes. I've kept fish from cataract to eat and I know of others who have also.

Also google indiana crappie and catfish guide service and check out Tom Hankins guide service. He is a great guy and a heck of a fisherman. He has pictures of alot of nice fish also.
Indiana slab masters puts on crappie tournaments that cost next to nothing to fish in and you can learn a ton from alot from all the guys fishing.
