How do quagga and zebra mussels spread from an affected water body to another water body?

Once an aquatic invasive species becomes established in a waterbody, it becomes increasingly difficult and costly to manage the population.

It only takes one plant fragment to start a new population of Eurasian watermilfoil.

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?

Zebra and quagga mussels attach themselves to hard surfaces tightly like superglue and are very difficult to remove without high pressure, hot water.

Inspectors will only need to do a visual inspection of the exterior of the watercraft.
