In the course of making a different post I realized I actually do have a technique I’ve found successful for catching post-spawn channels.
I found last year that in areas with a large, circular current or even below a dam where you have a back-current along the sides, tossing my regular catfish rig (3-4 oz weight, 3/0 to 6/0 circle hooks) out under a cigar bobber set to keep the bait at about half the depth of the water or just below REALLY kills the cats, especially if you toss it in just up river and let it drift into choke points or holding points downstream.
It makes it possible to fish structure that you just can’t fish otherwise, and it can really help in snaggy, boulder-strewn areas. Just be sure to keep an eye on your bobber and your line, because you will have to feed some and retrieve some as the bobber follows the current.
It’s kind of a take on the drift fishing technique we were talking about the other day, but I find it works really well in areas that you can’t get to by boat, or in areas that are big enough to need more coverage than one hook in one spot but not too big to be fished from shore. I’ve also found that a lot of places (like Coon Rapids Dam, for instance) make you fish from an elevated platform of some sort and this works really well for those circumstances as well.
I also found this to work best around dawn…
