1. What is allowed?  Dredges, Highbankers, Hand tools only?
2. How deep is the water.  Is it wade-able?   In google earth the water appears to be deep and fast.  
3. You mention bring a rope to lower yourself down. It appears there a a couple of trails in that area leading off the road.  Are those available?
4. I assume snake boots are a good idea and how much of a problem is there with bears and lions as you had mentioned in your post about the Pinion Bridge site?
