Nick of Time?

As reported by the Coolidge Examiner, a National Park Service employee discovered zebra mussels (Dreissena polymorpha) on the hull of a houseboat, fortunately before the boat was launched. The boat was brought to Lake Mead over Memorial Day weekend, all the way from Kentucky. The unlucky boatowner must now wait thirty days before his/her boat can be retrieved from quarantine. This map shows the known distribution of the zebra mussel in 2003 - Arizona isn't anywhere near there...yet.
