Hey kb I dove the ramp this weekend, and went to 120 off the ramp, you can go deeper, and there is a line to follow. When diving the ramp head stright out and you will see 2 training platforms, at the second one there is a line going down to a airplane wing, and prop, going down further you will be going thru some forest (trees) Viz was great and temps were 53. You might want to check out OTW diving at Jocassee, and get on the boat, for your dives. The number is 864 944-9255. Talk with Bill, and tell him what you would like to do. Going over by the wall would be better for your dives.
Also FYI for the other posts here. Dove the grave yard this weekend and it is at 120 ft. viz was great and the temp was also in the low 50's also went to the road that was going thru the vally it was at 139 ft a couple of great dives this weekend. Lake level is down 24 ft.
