Look for the shad. Jordan crappie as a rule don't stick tight to cover. They school under the shad, sometimes in winter they will be so close to bottom you can't see them. I don't like the s turns on weekend because of the traffic and it is narrow. I only fish the s turns on weed days. There are crappie all over Jordan. My guess right now would be some where around 20 ft but will come up on a warm day to get the sun. Good luck
