I don't know if the game dept.'s have such a program Tony. It sounds like a good idea, except for what you mentioned about training time. And likely getting enough willing qualified participants too. But I think it has potential. There are some guys in the know on here about such matters, and hopefully they will see this thread.
It seems to me that this kind of repeated problem occurs more often on Washington rivers. I don't know why that would be. Maybe because of the somewhat corraled and curtailed opportunity of Washington angling due to Indian river netting? ... Can you or someone up there ask the WDFW if they have such a program and let us know. While you are at it, ask them what they plan on doing about the fighting and snagging and littering that is happening for sure in such places as mentioned above.
Oregon does have some of this happening in isolated spots; again, seemingly to a lesser degree. Three that come to mind are around High Rocks on the lower Clackamas, the Willamette's Meldrun Bar bankies vs boaters (also near Oregon City), and at the 'launch hole' in Pacific City on north coastal Oregon's lower Nestucca River. Some real lowlifes there that do actually act like they own the rights to fish the public launch and river there, and reportedly gang up to try intimidating 'outsiders'!
