Ok I will Brag!!!! Just kidding...I think anyone here could catch the fish I caught last year, if they located them...To me that is the obvious key, you cant catch them if they aint there, no matter the tackle, no matter the bait....I am really down to just a select few spots I can fish right now, and they are a pain in the rear to get into, nothing easy about it...I know of many good areas for big Flatheads, that I just cant fish, because I dont have a boat, and because I cant get permission to bankfish.....
I personally know of 4 very very good flathead holes, deep water, and brush, bends in the river.....I fished these areas many years ago for Channels, long before I started Flathead Fishing..But now I cant gain access, "My soul for a 14ft jon boat"
I f you guys who have not caught any big flats can get access to private land that borders, rivers you can catch them also.....
Let me tell you about a hole that I have not been able to fish for years...This hole is on a creek appx 40yds wide...My old fishing buddy and I took his Jon boat on it years ago, and he had an old hummingbird depth finder....He messured a hole at over 40 feet deep!..I consider a good hole on this creek 10ft, but this baby measured 40ft, my the Flatheads have to be stacked up in there!
Three summers ago I tried to gain access to this spot, but was of course turned down...But the landowner was kind enough to inform me

That his Son had trotlined this hole the previous year, and that he caught 4 flatheads over 50-lbs out of it..And that he released them, and that he had been fishing it with a rod and reel, and had several fish break 40-lb test line...Dont know if it's true but I sure would like to find out....
