Pretty cool. Went to UR about a 2-3 miles from the dam. No shad cam, or even a fish ladder as far as I know, back then. Shad run was better on the Rappahanok at that time. They allow dipping down in VA, which is step away from throwing in some jumper leads.
I witnessed a trio of Sea lampreys making their way up Dickensen Creek, off of the Salmon River once. It was pretty wild; I had never even seen a live lamprey before. They began making a nest just down from the wooden bridge that spans the creek below the viaduct. They sure made a lot of racket!
