You can use that current to your advantage. When I river fish for cats, I use smelly bait, the smellier the better. Then use large a sinker that has an eye on it so your line runs through the eye, this way the fish doesn't feel all that weight. You can run your hook right up to the sinker, or use a large swivel and put about a foot of line between it and the hook so the sinker butts up against the swivel, then your line and hook hangs off the other end of the swivel. Then plop that stinky bait right into the current and let the current carry that stink to the fish. If the fish are active, as they should be now, they will follow the smell and come eat lunch. This is the way that I've always river fished for cats, both up here in WI and down in NC, and I have done really well using this method.
The trick is to have enough weight to hold the bait in place. In a swift current, it could take a few ounces of lead to do the job. On the fox in Big Bend, I normally used 2 to 2.5 ounces to hold the bait in place.
Good baits to use with this method: Fresh cut gills or carp (look up how to make a gut pocket with bluegills), chicken liver (use nylons to hold the liver to the hook), raw shrimp (works better if its left out for a day or 2 in the sun, just use latex or similar gloves while handling the rotting shrimp, that smell is hard to get out of your hands).
