New state regulations to help prevent the spread of quagga mussels and zebra mussels went into effect in Mar 2010. These regulatory measures, known as "Director's Orders," were authorized by the Aquatic Invasive Species Interdiction Act passed by the Arizona Legislature in 2009. The orders contain a list of aquatic invasive species for Arizona, a list of waters where aquatic invasive species are present, and mandatory conditions for the movement of watercraft.

The Arizona Plant Diagnostic Network is designed to link growers and master gardeners with plant experts in your community and with plant scientists at the University of Arizona. These experts are available to answer questions about plant health and help identify new and emerging plant pests and pathogens in Arizona. The goal is to increase public awareness of incoming threats to the plants and produce in our State.

If you plan to use your own boat or angler float tube, you’ll need a permit and a free 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.

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.
