Step-by-Step
How to Comply with AIS Requirements in Wyoming
Follow these steps to stay compliant with Wyoming's aquatic invasive species regulations:
1
Check Sticker & Inspection Requirements
Wyoming requires a mandatory watercraft inspection before launching on certain waters. No paid sticker is required, but you must stop at inspection stations when present.
2
Purchase Your AIS Sticker (If Required)
No paid AIS sticker purchase is required in Wyoming at this time. Check back annually as state requirements can change.
3
Practice Clean, Drain, Dry
Before leaving any boat launch - and before launching on a new water body - clean all visible aquatic plants and debris from your boat, trailer, and equipment. Drain all water from bilges, livewells, bait buckets, motor, and other water-holding compartments. Allow the boat to dry for at least 5 days before launching on a different water body, or use a high-pressure, hot-water wash.
4
Cooperate with Inspection Stations
Wyoming operates watercraft inspection stations at launch sites and on roadways. When you encounter an inspection station, stop and allow the inspector to check your boat. Inspections are typically free and quick - usually under 10 minutes. Refusing an inspection can result in a fine.
Noncompliance fine: Up to $10,000 civil fine for transporting AIS; misdemeanor criminal charges possible.
