mellin02,
I would start thinking about heading that way real soon. I will be there April 8 thru 11th at the LA Toledo bend state park North.
I would think they are moving into the shallows or at the least staging in about 10-12 feet waiting to go into the shadows.
Last year the first weekend in April I was there with some of my brothers and nephews and we really caught good. We kept a few but we did release most of them.
We fished a road-runner while keeping the boat in 12 feet of water, casting to the bank and reeling is back to the boat across the grass beds.
If you decide to go I sure hope you have some good luck.
I can't leave now; They fixen to turn on.
