Just got back from my fourth trip to the Ohio River. Thought I'd clean up on the blues because this exact time last year they were insane aggressive in the holes, biting everything. This time I got skunked. Caught some channels and flatheads, but no blues. ??? River rose five feet in the three days I was down there. The first day the current was fast enough that you had to let out 150 feet of line to get a three ounce sinker to touch down at 25 feet. By day three it took twice the weight and even more line. And that's using a two inch piece of cut shad. Is there such a thing as too fast of current for blue catfish? Used shad mostly, but also baby quillback and goldeye. We tried fronts and backs of holes up to 70 feet, shorelines next to holes, creek mouths, suspended and bottom fishing at the dam, side channels, flats around and behind an island, night and day fishing... The water temp is 79. Are they all spawning all at once? The bait seemed to be pressed into the slack areas, but all we caught there were the channels and flats. Which was great, of course, but we were after big blues! Where do the blues go in these conditions, this time of year? What did I do wrong? Any input would be great. I'm off to the lake now with the fam for a week (yeah, back-to-back fishing vacations... not bad), so if I don't respond right away, that's why.
