I got a question for you deep water fishermen. When going after fish in old river channels in lakes that are 20-30 feet, and you want to anchor up, how do you approach it? It seems that trying to drop an anchor in 20-30 feet of water requires a LOT of anchor rope to do it effectively. Do you anchor in shallow water and cast to the deeper water? If you are doing this, do you use a special rig to keep from snagging on steep channel banks? I have trolled and drifted through deep water channels, but never tried to fish them while anchored. My curiosity is up because I have marked a lot of large fish, maybe cats or maybe not, in deeper channels under bait fish schools and would like to give it a try to see if they are Mr. Whiskers.
