CPW launches ‘Oh Shell No’ campaign as zebra mussel threat continues in Colorado
Colorado Parks and Wildlife is launching an awareness campaign called “Oh Shell No” to address the spread of zebra mussels in the state, with a focus on impacts to agriculture and water infrastructure. In 2025, CPW detected adult zebra mussels in the Colorado River for the first time, as well as in smaller lakes and ponds in the Grand Junction area. … As temperatures rise, CPW plans to put more technicians in the field for sampling. The agency said it will focus monitoring efforts upstream of areas where zebra mussels have already been found.
