Obviously the trinity is flowing steadily right now. Lost 3 catfish rigs in the elm fork on Saturday.

Is it just inevitable with the amount of flooding?

How are you rigged up? Typically I try to fish with my bait/hook off the bottom and I will primarily find the slack water or an eddy. Typically your bigger fish are moving in the current but feeding in the slack water where the baitfish go to rest or to seek protection from the current.

Not sure what kind of rig you are using but, in faster water, I always use throw away sinkers (large bolts, spikes, etc) tied with an overhand knot on 4-5 lb test leader to a snap swivel if using a slip sinker rig or a three way if using a drop shot. I also put a small float on the bait line about 8" from the hook to keep it just off the bottom. The sinker is heavy enough to hold bottom but will pull off easily once it hangs up. Not fool proof but worth a try because the high water can hold some good fish although I generally bait fish within 3' of the bank in flood conditions so don't need a lot of weight.

As mentioned above the 3 way rig is the best bang for your $$$. Tie a swivel to the braided line then attach a 6"-8" wire leader (I usually get more gar than catfish) to the swivel with your flavor of hook then you can tie a sinker, nuts, bolts..I've even used rocks to a 12" piece of light weight mono line and attach to the swivel. More often than not if you get snagged all your high dollar gear comes to you with a good yank on the pole and all you have to do is attach another weight with mono and your back to fishing again. Another thing I have learned to is if your reeling in to re-bait or to cast to a different spot make sure you give a good yank up on the pole and reel it in like your life depends on it. It lifts your rig from the bottom of your fishing hole and less chance of a hang up on underwater obstacles.
