Staff collected samples of the adult zebra mussels in various locations and are currently evaluating options for the next steps in eradicating zebra mussels from the body of water.

“Understanding the current extent of zebra mussels in western Colorado is a critical step in stopping their spread into new locations,” said CPW Invasive Species Program Manager Robert Walters.
