Lake front property along Flathead Lake is currently valued at 6 to 8 billion dollars. Invasive mussels would cause a 13 to 19% drop in property values within 3 years ( a $1.5 billion drop).
Impacts to tourism, hydropower, and infrastructure (irrigation systems, power facilities, and municipal water supply and treatment) could cost more than $95 million a year.
Once established, invasive mussels will be here forever. They are virtually impossible to remove. The ONLY solution is PREVENTION.
