Flathead Lake Mussel Walk


Early detection of invasive mussels is paramount to preventing an infestation. Once mussels are established, it is impossible to get rid of them.  Join our community effort to keep a watchful eye on Flathead Lake and watershed.  

Community mussel walks: 

  • May 14, Flathead Lake State Park: Wayfarers Unit, Bigfork
  • May 20, Flathead Lake Biological Station, Yellow Bay
  • May 21, Salish Building, Polson
  • May 22, Whitefish City Beach and State Park

Begins at 9:00 with educational activities and mussel detecting dog demo, followed by the mussel walk and beach clean-up.
