I think it will get used by summer crappie in the hottest parts of summer. Crappie on deep lakes will suspend in deep water along channel edges or other structure and if they have cover to use I'm sure they will use it. The only concern I would have is 20' may be a little deep for the thermocline. Need to study it on the Hill. I do know the creek runs do hold crappie all year long but not in the numbers like the spring and fall. If you do place them in deep water you really need to keep watch on them because if they break lose they may be trouble for boaters.
