Taking emergency action to prevent the possible extinction of native kokanee salmon

A work group created by King County is taking emergency and long-term action to counter an alarming downward trend of Lake Sammamish kokanee, a native salmon population that appears closer than ever to extinction.

County and state biologists counted fewer than 20 kokanee in the most recent return, five years after more than 18,000 spawners returned from Lake Sammamish.

“The native kokanee salmon – important to our history, our culture, our environment – are facing new challenges that potentially threaten their very existence,” said King County Executive Dow Constantine. “Together with our partners, we will take new, immediate actions to protect the iconic species and continue our long-term work to create healthier salmon habitats throughout our region.”
