If all the states honored a decontamination at Lake Powell I would probably agree with you. But they don't. At least Colorado doesn't. So if my boat gets decontaminated at Powell, I have to take it home and get it deconed again. Which is why I wouldn't wait or pay for a decontamination in Utah.That's not unrealistic if the mussels are attached with byssal threads. Julie clearly noted that when watercraft is found with byssal thread attachment that not only is a decon required, but so is a mandatory 30 day quarantine.
It is a boaters responsibility to understand the requirements, and risks associated with boating on Lake Powell. If you plan on mooring your boat for 2 weeks at Powell, you should also plan on having a mussel issue, and your boat will need to go through proper protocol prior to transporting away from Powell.
I'm not sure how a national registration system would work, but that seems to be what is needed. Record the boats registration numbers when they go in/out of Powell. And make sure that they are decontaminated before they launch at the next clean lake.
If someone from out of state risks having their boat quarantined hundreds (or thousands) of miles away from home, they will likely circumvent the system (which is pretty easy to do right now). Which will increase the risk of spreading the mussels.
I hate to be defeatist, but at this point with as much as the system is still "evolving", I find it very difficult to believe that the infestation will be confined to Powell. It seems inevitable that it will spread.
