I spent three years going to meetings and advocating for the private boaters during the "Snake river plan" in Jackson Hole. There was very little participation from the public but a few of us were able to aggressively make our points.
Our big concern was that outfitters had overwhelmed the Wilson ramp that accesses an easy scenic section that is only a short distance from town. With no rules, capacity restrictions, or oversight, things were heading south in a huge hurry. Greed was the motivating factor for many of the outfitters and they were fighting each other over how many boats they were going to get.
Eventually our county commissioners hired Doug Whittaker and Bo Shelby consultants and authors of "allocating river use: A review of approaches and existing systems".
These guys know rivers! They were extremely helpful and brought an amazing amount of expertise to the table.
I suggest you get a copy of their book, read it, and pass it around to the powers that be. That should give you a baseline knowledge of how these things can work. Bo and Doug, of Confluence research and consulting can be contacted @ Confluence
