They should be in the same spots as when there was ice if not I look for a spot that warms up fast or a deep weed bed next to where they spawn. A good lure to start with would be a road runner with a gulp minnow grub tail thats my fav when Im looking for them then when I find where they are you can slow down with minnows or tubes under a float. the funnest part of crappie fishing fore me is trying differnt lures and finding where they are.Last year I caught crappie all year long with 1" gulp alive minnows small jig head under a float and lake fork baby shad on a 1/16 scronger head. 13 feet is not very deep so you shouldent have a problem getting the bait to them good luck and have fun
