I used to fish Barren regularly and put out crappie beds each winter. Been ten years or more since we did that. Barren has always been decent for crappie but the corps tends to jack with the water too much right when they want to spawn and you can lose a whole year class of fish that way.
You might be a bit early for hybrids in the jumps.
I would recommend long line trolling crankbaits now. You will get into hybrids, yellow bass and crappie that way.
