In 2007, quagga mussels were detected in the Colorado River (feeding Lake Mead, Lake Mojave, and Lake Havasu) while zebra mussels were found in the San Justo Reservoir in California in 2008.
Between 2007 and 2015 monitoring and sampling was performed in 425 lakes across 15 states. In 2017, the U.S. Department of the Interior released a set of actions and initiatives titled “Safeguarding the West” to manage invasive mussels in the West and prevent further expansions of invasive mussel populations developed in collaboration with more than 70 federal, state, and tribal entities. Action items are organized under the following priorities:
• Prevention
• Early Detection Monitoring
• Rapid Response
• Containment and Control
• Outreach and Education
• Research
• Increasing Capacity
