Thanks Al, it will be a memorable visit me thinks. Actually I need to go there at least twice, once by car and taking astro & bushwalking gear; and once by mountain bike and then fly out to Camden. The latter would be a great adventure, but transport will be a killer (I'm not keen to ride all the way from Tahmoor via Katoomba, and do they take bikes on the plane

I don't know)
Barry, most of the road from Nattai is probably still there, just closed off. My partner's dad helped build that dam, but it sure created some obstacles didn't it
Never made it down there when it was still easy. The Yerranderie website mentions 4WD trips across under special permits several times a year. They must be using parts of that old route. Would have been interesting to see the remains of old Burragorang town when the water level was really low a couple of years ago.
