It's the Law: The Environment and Your Vessel

Aquatic Nuisance Species (ANS) / Aquatic Invasive Species (AIS)

The introduction of non-native species into Washington waters has hurt many of our native species and has caused environmental, economic, and recreational damage. There are several species, such as zebra/quagga mussels, not currently in Washington, which would have devastating effects if they were to enter our waters. Hitching a ride on vessels and trailers is the most common way that ANS/AIS are spread. In Washington, it is illegal to transport or spread ANS/AIS!

Clean your vessel between uses, especially if it has been used in another state. Wash the vessel, the trailer, any holds, and the engine with hot (140° F or greater) water.

Before leaving the boating area:

• Remove all plants and animals from the vessel and trailer.
• Remove the drain plug. Then drain live wells, holds, and the bilge in a location that will not contaminate the waterway.

Help Protect Marine Mammals

To protect marine mammals, boaters should follow these guidelines.

• Do not approach marine mammals closer than 100 yards.
• Do not separate mothers from their offspring.
• Approach whales slowly from the side; travel parallel to them and at the same speed as the slowest animals.
