Thank you for the reminder.
If I remember correctly this means very hot water, or a continuous freeze for three days, or dry for a month. Utah considers all of Colorado's water suspect, and you are supposed to use one of these methods before you put a boat in there water.
Even with periodic testing of water body's though, you can still end up with mussels after a test, allowing them to continue there spread, I wonder if we need to look into a better decontamination method for inflatables, to be used every time?
Unfortunately I get the feeling no matter how much testing they do, the stuff will continue to spread, kinda like Tamarisk.
Willing to help fund testing if it is really needed, just not by registering non motorized craft. Don't trust the State of Colorado with requiring registration, partly because of how they handled Motor Vehicle registration in the last few years.
