First off WELCOME TO THE SITE!
I'm far from an expert on Jordan but from the information available your best bet for this time of year would be around the 64 bridge. Fish minnows, start a foot off the bottom and move up a foot at a time till you connect.
That being said, with your rig, it could get pretty hairy out there pretty quick. With the current water temps a dunk could be very bad news.
If I were you I'd focus on some smaller waters which are less susceptible to wind and boat wakes. The Eno ain't that far from Jordan - as things go- and can be very productive. Minnows on jigheads or C&C rigs work fine. From my experience in these temps slow ain't slow enough .. sometimes an almost dead minnow produces better than a lively one. Also I've found that the fish stick tighter to the bottom than most other times of the year, so when you mark fish(or think you have), drop to the bottom and bring the bait up a foot or 2, repeat till you get bit.
Lastly, I realize that budgets are tight these days, but a trolling motor is at least as useful to a crappie fisherman as the depthfinder. If I had to fish with a cane pole and just a handful of tackle in order to afford one I'd make that choice.
You just gonna sit there an argue, or fish?
