Elwha Watershed Information Resource

The two dams on the Elwha River have severely impacted fish runs in the watershed in many ways, including:

• Preventing migrating fish (such as Chinook salmon) from traveling upriver to spawn;

• Increasing the temperature of the river water; and

• Decreasing spawning habitat by restricting the natural transport of sediment and debris.

Removing the Elwha and Glines Canyon Dams is a critical component in restoring depleted fish populations in the river. Removal of the dams will allow fish to access the middle and upper reaches of the Elwha River. Removing the dams will also decrease water temperature and re-establish the natural flow of debris down river--both of which are important in restoring fish populations.

Fish in the Elwha: Many fished lived in the Elwha River historically, including five species of salmon. Learn about the history and status of fish species and the genetics research that will help monitor the progress of the fish restoration efforts.

Fish Management Plan: Read about the plan for restoring fish runs in the Elwha River.

Hatchery: Information on current hatchery production and the new hatchery facility.

Tagging and telemetry: Radio and acoustic tagging studies are being used to monitor juvenile and adult Elwha River fish movements, behavior, and distributions in order to determine the most effective restoration projects.
