Leyland600:
Dean, I drove up the access road to the dam one evening in 1965 in my Mini without any restriction, no NO ENTRY signs or anything like that and took these photos. I visited the power station and did the official tour with a coach party when on tour to Oban with my Leyland Leopard about 1990.
Cheers, Leyland 600.
