Prevent the transport of aquatic invasive species to Yellowstone by making sure you clean, drain, and dry your boat before you arrive.
Exploring Yellowstone’s lakes by boat offers a great way to see the park from a different perspective. However, boating in the Northern Rockies presents significant risks. Water temperatures on park lakes are in the 40s (Fahrenheit) in June, and may reach the 60s by late summer. In addition, sudden strong winds can produce three to five foot waves, making open-water crossings very dangerous. Boaters in canoes, kayaks, and other small craft must be aware of these hazards and plan accordingly.
If you plan to use your own boat or angler float tube, you’ll need a permit and a Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.
Permits and inspections are issued at the locations listed below. These facilities are open seven days a week from 8 am to 4:30 pm during the summer season. Boating season opens on the Saturday of Memorial day and ends October 31.
