Prevent Aquatic Nuisance Species
Wyoming Game and Fish and Grand Teton National Park are concerned about the spread of Aquatic Nuisance Species (ANS) also known as Aquatic Invasive Species (AIS). The state of Wyoming is trying to minimize the threat to waterways by mandating inspections for all boats entering the state, and requiring the purchase of a Inspection Decal.

Aquatic Nuisance Species Pose a Serious Threat to the Aquatic Ecosystem
DRAIN - CLEAN - DRY
Aquatic invasive species, such as whirling disease and zebra or quagga mussels, are a serious ecological and economic threat to the Greater Yellowstone Ecosystem. Any activities that come in contact with any body of water have the potential to spread non-native plants, pathogens, and other invasive species among water bodies. Follow these steps every time you come in contact with any body of water:
1. Remove all visible mud, plants, fish, or other tiny animals from your boats, trailers, and other equipment, including waders, boots, clothing, and nets.
2. Eliminate water from all equipment before transporting anywhere. Much of the recreational equipment used in water contains spots where water can collect and potentially harbor these aquatic hitchhikers. Drain your boat hull and live well in a safe location (a flat paved, dirt, or gravel area) away from all park surface waters.
3. Clean and dry everything that comes in contact with water before entering a new body of water. It is best to use high-pressure, hot water (available at car washes outside the park) to clean your boat, trailer, and gear.
4. Dry Equipment. If possible, allow 5 days of drying time before entering new waters.
