No recent fishing reports, but you have to keep in mind that Cordell Hull is a bit of a different lake. Most of the river flow coming into the lake is from the cold water discharges upstream from both Lake Cumberland and Dale Hollow. Waters temps in the main channel of the lake are usually vastly different from those back in the creeks. Your friend will likely have to do some searching around to find the "right" temperature that both he and the fish are comfortable with.
Good luck!
