I've never fished there, however I've fished the James, New, Doah rivers.
depending on water clarity, I'd stick with natural colors if clear, senkos, grubs, lizards, in green pumpkin or watermelon.
If stained then chartreuse or purple, plastics, spinnerbaits.
the NED rig is a good smallie lure, however I find that it does get snagged in rocks.
good luck, looking forward to your follow up report.
