What should I expect from an inspection?Inspectors are trained to:
- Introduce themselves as a watercraft inspector.
- Provide tips on how to inspect your own equipment.
- Physically inspect your boat, trailer and any other water-related equipment— meaning they may touch your boat or trailer to feel for tiny, attached zebra mussels or other invasive species.
- Physically inspect compartments that may hold water, such as live wells or bilge areas.
- Deny launch if: 1) the inspector finds invasive species or any plants attached, and until the invasive species or plants are removed; or 2) you refuse an inspection; or 3) if water that cannot be drained is found.
- Although inspectors have the authority to deny launch, they will work with you to try to bring your watercraft into compliance.
- Inspectors will not deny launch based solely on where, or when, you last used your watercraft.
- Ask questions to help improve the DNR’s inspection program. You are not required to answer these questions.
How should I prepare for an inspection?When entering an access:
- Always follow all state laws regarding AIS and arrive in compliance with Clean, Drain and Dispose laws.
- Open the lids of closed compartments that could hold water, like live wells, so the inspector can see they are drained. Your drain plugs should all be open while you transport your boat.
- Remember to install the drain plug after the inspection and before launching.
When exiting an access:
- Remove any plants, mud, and invasive animals.
- Pull all drain plugs.
- Open water-holding compartments to allow inspection.
What about Decontamination?DNR trained inspectors follow specific decontamination protocols using hot water (120 degrees for at least two minutes or 140 degrees for at least 10 seconds) to kill AIS and, if necessary, using high-pressure water to remove attached AIS. An inspector may require your watercraft to be decontaminated prior to launching or before leaving an access. Decontaminations are free and most can be done quickly.
How do I find a decontamination station?The DNR posts decontamination unit locations online at
mndnr.gov/decon. At these sites, inspectors will perform a courtesy inspection and determine if any decontamination is required.
