My wife worked at River Country back in the summer of 1991. During the year of a Million Dreams, we went to DW and due to an extremely nice CM we were offered the opportunity to visit RC.
We were taken behind the locked gate and covered fence by the top Disney employee who was the head of the Campground resourt. With us was the head of all Disney water transportation. We walked onto the docks, and next to the pools with the slides. We were told not to get to close as they don't maintain anything, and aren't sure what wil support us, and what will break.
We were able to go into all the rooms that my wife worked in, and see what has become of it now.
When we asked why it was this way, we were told that once Typhoon Lagoon opened, very few people came to RC. The ampount of guests needed to make a profit was not being met, so they closed the waterpark. When we asked why they left it like that, we were told that until Disney needed the space they wouldn't maintain it. Since they could block off most of it behind fences, thats what they did. When, and if, they need that area, they will demolish the remains.
It was a very interesting behind the scenes tour.
Was was the most interesting part was that they allowed us to take photos, and the cast members who came with us were taking them also.
