Correct me if I am wrong, but it seems that this clause will protect you:
"The amount of alcohol, as shown by analysis of the person's blood or breath, in the person's blood is 0.08 or more grams of alcohol per one hundred milliliters of blood or 0.08 or more grams of alcohol per two hundred ten liters of breath at the time of the commission of the alleged offense or within two hours after operating a vessel, if the evidence establishes beyond a reasonable doubt that the person did not consume any alcohol between the time of operation and the time of testing
Just take a good old chug out of that last bottle of whisky right after the ranger calls you out. Or just open a bottle at the take out...he can give you a public consumption of alcohol ticket, but can't prove that your intoxicated state began on the river. Just stash the green, and don't sniff any glue if you patch your boat.

The law states:
"A person who operates a vessel or who is in actual physical control of a vessel on the waters of this state shall be deemed to have expressed consent to the provisions of this subsection (4)."
So you don't need to sign anything to be held under its provisions.
And in defense of Utah rangers at least, we've shared beer and a bag of wine with some cool rangers at the cisco takeout.
