    Lake Jocassee conditions yesterday @ the graveyard and wall

    Dove the junk for the first time yesterday. Then dove along the top of some trench at around 75 ft. Only my 10th dive so i'm still learning but was a lot of fun. Saw a lot of big fish in and around the junk. Striper maybe? Thats what i thought they looked like. And a few catfish around leddges.
