I live in Oklahoma on Lake Hudson, I can go out and catch a lot of blues, but I just seem to never be able to find a good flathead hole. There is a river channel that runs through the lake that is on average 35-45 foot deep. I have not been able to locate any log jams or much structure to fish at all. There is a bridge that the channel goes under that is around 50' deep. When fishing for flatheads I know they prefer live bait. Should a guy always fish on the bottom of the lake or have bait at several different levels? Anyone ever tried goldfish. We are getting a lot of rain right now and the lake has been down about 4-5 feet and now it is up about 1'. There are several creeks that flow into the main lake, anyone have any tips?
