All boaters recreating in Grand Teton National Park must self-certify that your boat is aquatic nuisance free. More>>

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.
Did You Know?
Did you know that the black stripe, or dike, on the face of Mount Moran is 150 feet wide and extends six or seven miles westward? The black dike was once molten magma that squeezed into a crack when the rocks were deep underground, and has since been lifted skyward by movement on the Teton fault.
