All boaters in Utah, including users of motorized vessels, kayaks, canoes, and paddleboards, must complete an annual mussel-aware boater course before launching in state waters to prevent the spread of invasive species.
Proof of course completion requirements
The Utah Division of Wildlife Resources requires all participants to carry proof of course completion, either as a printed copy or via the DWR Hunting and Fishing mobile app. For those using motorized watercraft, additional requirements include enrolling in the Utah AIS Program and paying an annual fee of $20 for residents or $25 for nonresidents.
Motorized boaters decal and inspection rules
The Division of Wildlife Resources noted that motorized boaters must obtain a current-year AIS decal, as the Utah Division of Motor Vehicles no longer accepts these payments during the standard registration process. Boaters are also required to stop at all active AIS inspection stations.
Threats posed by invasive quagga mussels
The regulations specifically target the prevention of quagga mussels, which currently exist in Lake Powell but threaten all Utah waterbodies. These invasive species can plug water lines, damage engine cooling systems, and harm fish populations by removing plankton from the water.
Decontamination protocols for visiting boaters
Boaters arriving from other states or those who have visited mussel-infested waters like Lake Powell within the last 30 days must either undergo a professional decontamination or complete a full clean, drain, and dry process. The Division of Wildlife Resources provides an online platform for the 2026 Mussel-Aware Boater Program and certificate lookups.
