Study: “Trapped” Elwha River Steelhead Maintained Genetic Diversity While Isolated Above Former Dam

The Elwha River continues to be a beacon of hope for what can happen when watersheds are returned to their natural state, free of manmade dams. A study, which began back in 2004, has determined that the steelhead population trapped above the (former) Elwha Dam maintained their genetic diversity as well as the genetics necessary … Continue reading Study: “Trapped” Elwha River Steelhead Maintained Genetic Diversity While Isolated Above Former Dam
