Aquatic Invasive Species Program Informational Guide

This guide provides information about how to stop the spread of invasive quagga mussels when boating in Arizona waters.

Vessel Decontamination

• In Arizona: To schedule a FREE vessel decontamination, call 623-236-7608.
• In California: To schedule a FREE vessel decontamination, call 928-412-5965.

Decontaminations are conducted at the Bureau of Land Management (BLM) Rock House Recreation Area.

How does a free boat decontamination work?

• Water is heated to a boat-safe temperature and applied just long enough to kill the mussels. All areas of the vessel that could house mussels are treated.
• The time it takes to decontaminate a boat varies depending on the size of the vessel, the number of internal compartments, and the amount of mussels or debris present.
• Transporting invasive species may result in fines or quarantine of the vessel. Vessel decontaminations are available at the BLM Rock House Recreation Area on the Parker Strip.

Going Beyond CLEAN, DRAIN, DRY

Time in the Water

If your vessel has been launched, moored, docked, or trailered in Lake Havasu or along the Parker Strip, your vessel may be transporting aquatic invasive species.

Transporting aquatic invasive species is against the law. Consider getting a free inspection or decontamination before leaving.

Cool Temperatures

During cooler months, quagga mussels can survive on dry land for weeks. This increases risk of transport by recreational boaters. Call your local fish and game office to find out dry times for your vessel.

Why are quagga mussels a concern?

Environmental Impacts

• Increased blue-green algae blooms
• Decreased food availability for aquatic species
• Damage to aquatic habitat

Economic Impacts

• Clogging water control structures
• Damaging boat motors
• Increased maintenance at dams, marinas, and shoreline structures
