I doubt they'll go deeper, but you might want to go for a brighter color on your lures or something with more flash. All the run-off is going to bring in a lot of silt, making it harder for them to see stuff. They'll be in their beds soon if they aren't already, a thermometer that you can find the thermocline with somehow would be the best way to know exactly where they'll be. Barring that, you've got two lines each, so go deep and shallow or bright and dull.
I'm not an avid bass fisherman, so I only know so much, though.
