Boats to be inspected for harmful mussels
Any vessel found with live, adult zebra mussels attached to it will be quarantined until a biologist determines it's safe to launch. Random inspections of all boats entering Lake Powell have already begun, the National Park Service recently announced.
Invasive mussels are still considered a threat to Lake Powell, having already been found in Nevada's Lake Mead. If anyone violates Lake Powell's self-certification and decontamination process to keep mussels out of the ecosystem, they face a mandatory court appearance and a $5,000 fine.
