I went out on the muskingum monday afternoon. I caught one 15lb flathead, and 6 channels, the largest being in the 7-8 lb range. I caught the flat at my first anchor site at 2:30 pm. I caught the largest channel at my last site right around 8:30-9:00 pm. I was using cut shad for bait. I should have changed from my 10/0 hooks down to 8's and I would have caught many more fish lol. I didn't catch any more fish after that, I stayed till 11:00pm. The water is cold now, I didn't get a temp reading. But the fish are active if you can find them and still fighting when you hook em. The bite slowed the closer to sunset it got. If you head out now start in the morning and fish till dark. You need to fish every hole you know of and when you catch fish, concentrate on that hole. There will be more than just the one there. As to flats and channels in the same hole I'd say most of the time they will not be together. But that still leaves a little room for the more active channels to cruise thru a flathead wintering area. You can catch channels in a flathead hole, but overall if you are catching only and many channels, you will have to look elswhere for flatheads.
