I fished for flatheads for most of my life on the Colorado River before changing to blues in lakes. I have set a few trotlines in lakes for flatheads without much luck. I would appreciate any advice from anyone who could help me. I would like to know about how to select trotline or jug locations for different times of year. Any tips as to how to set a trotline in a lake, depths to fish, rock staggging length, ect would be great. Where and how would you go about it right now?
