What would you say the best catfish rig would be for these fishing conditions?

I have been fishing in the spillway next to the lift gates in the dam lately. The railing is approximately 30ft up from the top of the water, and the water is approximately 23ft deep. Since they opened the second gate for winter pool, the water moves REALLY fast in that spot and the water visibility is stained.

I know there are lots of BIG cats on the bottom of that area, because people are still catching a lot of them. I was also catching a lot there before they opened the second gate using dip bait, but now the water is moving so fast it washes it off, so that is no longer an option. Now I need to change my method. Last night I went out there with nightcrawlers and used a 1oz. weight each of these tied to a leader on one of those three way swivels. The cats kept grabbing the nightcrawler, but would let it go once they felt the weight. I also had trouble with the line sweeping down the area and tangling in other fisherman's lines, so I know I need a heavier weight that won't easily get hung in the rip-rap rocks on the bottom. I also had an issue with the hook leader getting tangle around the weight leader, is there anyway to prevent this?

Does anyone have any suggestion of how I should set up my line to catch catfish in these conditions? I will probably be using Turkey Livers this weekend as well as nightcrawlers. Any suggestions at all would be appreciated. Thanks.
Dane, that is close to what I did last night. Only I used mono for both leaders. I used 20lb braided for my main line. Attached a three way swivel. One one of the loops I attached a mono leader with the 1oz weight, and on the other loop I attached a mono leader with a Blood Red 4/0 Eagle Claw Off Shank Wide Worm Hook. The problem I had was the hook leader kept wrapping around the other line. Any suggestion on how to stop this?
