This is what the Enviromental Protection Agency was created for.   Why is Colorado scrounging around for nickels and dimes to fight this menace imported from other states which ultimately costs downriver States and Colorado billions?  It is a national problem and the EPA is a National Agency.  Take some of the money being wasted on theoretical man-made climate change research and apply it to actual Earth-made mussel infestation.  You can't blame energy companies for this one and unless you want to outlaw boaters, the EPA should do its job and Protect the Environment.
