Assuming the river is back down to a decent stage, you'd wanna use leeches or Woolie buggers, or a caddis larvae imitation, like a brassie.. Dark green works best.. Egg patterns would be another fly suggestion.. Whatever it is you fish with, bring along plenty of shot to get it close to the bottom..

Dinner in the area? I'd suggest Sand Springs Diner, Circle J or Ollies.. (listed in order of proximity, not favorability)
