Our Great Migrators

May 21, 2014

*NWNL thoughts prior to World Fish Migration Day-5/24.*

Many are unaware of the exquisite sarabande of life personified by our migratory species: anadromous fish, birds, monarch butterflies, dragonflies and others.

Most migratory species are threatened in one form or another during their annual passages by manmade impediments. Today, on expedition along the Snake River, NWNL is following the struggle of the Columbia River migratory salmon, steelhead and lamprey to overcome dams, pollution, warmer streams and other challenges as they seek their traditional spawning grounds. Fish passages at dams and fish hatcheries have helped them avoid extinction, but more help is needed to bring back healthy numbers of salmon.

US: Washington, Columbia River Basin, Ice Harbor Dam on the Snake River, bypass for juvenile salmon migrating downstream.
