In the state of Washington you can be fined for towing a boat/trailer on the road with plant fragments attached.

Quagga and zebra mussels came to North America in the ballast tanks and on the anchor chains of large, transoceanic ships that entered the Great Lakes.

Adult quagga and zebra mussels can survive out of the water for up to 30 days.

Inspectors will ask you where and when your watercraft was last used.

Zebra and Quagga mussels are already present in Whatcom County lakes?

If you get a wire seal attached to your boat and trailer when leaving Lake Whatcom, and then come back to Lake Whatcom another day with the tether still intact, will you need to stop at a staffed inspection station?
