The Scale of the Infestation and its Location

Approximately 5,000 zebra mussels (Dreissena polymorpha) were discovered clinging to a large, privately-owned boat lift situated on the North Platte River near the Casper Boat Club. The boat lift, a substantial structure capable of handling boats up to 25 feet, was heavily infested, with mussels covering nearly 75% of its submerged surfaces.

• The most heavily infested areas were the lower support beams and the lift mechanism itself.
• We estimate the total area covered by zebra mussels to be approximately 150 square feet.
• The density of the infestation suggests a prolonged period of unchecked growth.

Environmental Concerns and Impact of Zebra Mussel Infestations

Zebra mussels are notorious for their devastating ecological impact. Their rapid reproduction and ability to outcompete native species for food and habitat have far-reaching consequences. In Casper, this infestation threatens the delicate balance of the North Platte River ecosystem.

• Native Mussel Populations: Zebra mussels will directly compete with native mussel species for resources, potentially leading to their decline or extinction.
• Economic Impacts: The clogging of water intake pipes in power plants, irrigation systems, and municipal water supplies can lead to expensive repairs and disruptions to service. This can significantly impact the local economy.
• Water Quality: Zebra mussels filter large volumes of water, which can alter water clarity and nutrient cycles. This can negatively impact aquatic plants and animals.
• Recreational Activities: Sharp shells can make swimming and wading in infested areas unpleasant and potentially hazardous. The presence of zebra mussels can also reduce the appeal of recreational activities dependent on clean, healthy waterways.

Response and Prevention Measures

Following the discovery, the Wyoming Game and Fish Department, in collaboration with local authorities, immediately initiated a response plan. This included:

• Decontamination Procedures: The infested boat lift is undergoing a rigorous decontamination process using approved methods to eliminate the zebra mussels and prevent further spread. This includes high-pressure washing, chemical treatment, and thorough drying.
• Public Awareness Campaign: Educational materials are being distributed to boat owners and the public emphasizing the importance of boat cleaning and inspection.
• Resources for Boat Owners: The Wyoming Game and Fish Department's website offers comprehensive guides on preventing the spread of aquatic invasive species.

The Role of Boat Owners in Preventing Future Infestations

Preventing the spread of zebra mussels relies heavily on the responsible actions of boat owners. Thorough cleaning and inspection are crucial.

• Before launching: Inspect your boat, trailer, and equipment for any zebra mussels or their veligers (larvae).
• After leaving the water: Remove all visible aquatic plants and animals from your boat, trailer, and equipment.
• Clean and dry: Thoroughly wash your boat, trailer, and equipment with hot, soapy water and then rinse with clean water. Allow everything to dry completely for at least 5 days before transporting to another body of water.

Protecting Casper from Future Zebra Mussel Infestations: A Call to Action
