Even if there were (and I assume there are and you're being sarcastic), it wouldn't help me get one. I still can't make myself stop fishing and switch to microfishing, especially in that spot, where 5 species of redhorse, hogsuckers, white suckers, and a bunch of non-sucker species, including longnose gar, have been sampled (by others) or caught (by me).
I'd love to see how you'd microfish inside the torrent coming over the falls, though. (Not sarcasm: I'd like to see somebody engineer a solution to that challenge.)
Meet me there in June?
With only two rods per person in Illinois, it does make it pretty tough to decide what to fish for. I feel your pain. However, a few thoughts:
1) You could give microfishing a try for 15 minutes - rigging up a presnelled Tanago hook takes no time at all.
2) Rainbow darters are one of the most aggressive darter species I've encountered. They will swim up off the bottom and chase your bait as you pull it away from them. There are times when they won't stop attacking your split shot, which makes it tough to get them to notice the bait!
3) For high current, I use pretty large split shot, about the size of a big pea. I've used as many as three of them for really high flow. I put them very close to the hook - about an inch away - so the bait doesn't flop about in the turbulent water.
4) If I'm concerned that I won't feel bites, I just twitch the rod tip every few seconds on the off chance that the darter is just sitting there with the bait in its mouth.
Since you say there are 5 species of redhorse there, and I have only caught 3, then yes I will join you, haha.
