I havent been up there yet but I think they are catching a few. I had one big fish pull off the last time I was around the nuke plant but it was still a little slower then it gets in the summer that was 2 weeks ago though so it may be a little better. if you can get skipjacks for bait you should be alright just setting up on the channel edges if you can find any distinguishing feature to set up on. I can meet you up there sometime and show you some specific spots that work well for me.
I was there today loaded for big ones and ZEROED!! I did see some guys pulling in some smaller ones. I would suggest checking the generation schedule, There was 0.00000 current there today, and i never do any good there if there is no current. Zeroed at the bluffs too. ditto in the current.
If you can find them, there are a number of 8 to 12 pounders that school up there. Use cut bait on the bottom on the downstream side of the downriver discharge, I often find them in 50 to 52 feet of water, but they stay very tightly schooled. This is as of yesterday. Good fishing with the kids!
