I've also wondered what the ramifications might be if a non-tribal member fished the Skok. The best outcome is that you'd never be contacted by anyone. However, if WDFW has it closed by their regulation you could be cited by them. Their is an argument that the tribe has no criminal authority over non-members on the reservation, or U&A. But, there might be a civil process that I'm unaware of wherein the tribe could seize your gear (and maybe your boat). Could be a real mess.
