Lamprey spawning siting

A few Inter-Fluve staff (Greg Koonce, Mike McAllister, and Josh Epstein) had the rare opportunity to observe several Pacific Lamprey spawning along a 2,500-foot long side channel of Washington’s East Fork Lewis River. While not officially listed, Pacific lamprey have declined in abundance due to a variety factors similar to salmon. Historically widespread along the West Coast of the United States, they live in the ocean for 1-2 years before returning to fresh water to spawn in habitat similar to that of salmon and trout.
