This handbook includes six chapters that discuss invasive species and their environmental, economic, and health impacts. It also reviews pathways of invasive species spread and prevention, monitoring, and control. The handbook is a resource for educators teaching children in grades 3 through 8. Learning objectives, activities, and vocabulary are also included.

The Utah Division of Wildlife Resources, Clean Wake LLC, the National Park Service at Glen Canyon National Recreation Area, the U.S. Bureau of Reclamation and other partnering agencies are excited to announce a new first-of-its-kind dip tank method (YouTube video - Lake Powell AIS Dip Tank) that will revolutionize boat decontamination in the fight against invasive quagga mussels.

Quagga mussel larvae, or veligers, were first confirmed in Lake Powell in late 2012 after routine water monitoring tests discovered mussel DNA in water samples taken from the vicinity of Antelope Point and the Glen Canyon Dam. As of early 2016, thousands of adult quagga mussels have been found in Lake Powell, attached to canyon walls, the Glen Canyon Dam, boats, and other underwater structures, especially in the southern portions of the lake. It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures.
