Inspecting your boat or other watercraft for aquatic invasive species is required in many states.
Use the free Expect to Inspect mapping tool to ensure your watercraft is safe, secure, and free of aquatic invasive species. The map also includes self-service, free-to-use cleaning stations.
Scroll down further to see a list of laws and regulations on AIS for every state.
Important: While cleaning stations are a great resource, they DO NOT count as a required inspection, and do not give permission to launch.

ALL motorized boats used in Utah waters that are not currently registered through the Utah Division of Motor Vehicles are subject to a $25 AIS vessel enrollment fee, and all boaters must complete an annual mussel-aware boater education course prior to enrolling.
Follow these steps to meet the requirements:
1) Register your vessel in your state of residence. You will need your bow number for your Utah nonresident AIS vessel enrollment (see step 3).
2) Take the free mussel-aware boater online course. This course is designed to educate boaters about quagga mussels, their impacts and relevant aquatic invasive species laws in Utah. (You must take this course before enrolling your vessel; please note your “Customer ID” information upon completion.)
3) Using your customer ID, complete the AIS vessel enrollment and pay the $25 nonresident boater fee (good for the current calendar year).
4) You will receive a current-year Utah AIS decal in the mail to affix to your vessel. Placement instructions are provided with the decal.
5) When boating anywhere in Utah, make sure that a printed copy of your AIS vessel enrollment certification is displayed on the dash of your towing vehicle, and that you have a current-year Utah AIS decal affixed to your boat.
Note: These steps must be completed prior to arriving in Utah.
Do I need to complete the online education course and pay the fee to use my SUP, kayak, canoe, etc.?
