I would think that the crappie may scatter and go deeper in the water as to find better and clearer water conditions. You may want to use your darker colors like black, purple, or blue/chartreuse jig colors or go live bait like minnows.
Here in Arkansas we just had a ton of rain. Crappie have been on brushpiles in 10 FOW. What do you think that this cooler, rising, muddy water will cause these crappie to do now?

Be safe and good luck fishing
If it was a really fast rise in water level I'd start by pulling back to the first major depth contour change/break and start there as the fish pull pack from the banks. After a couple days of stabilizing they'll be exploring the newly flooded brush in a foot or two of water.
I've heard people say that sometimes they stay where they're at and you just have to fish deeper. Now on Nimrod Lake when we have it at flood stage and after it clears the crappie like to set in top of the flooded green buckbrush and ambush shad moving in and out.
