Elwha Fish Restoration
"The restoration of depleted fish stocks and threatened or endangered species is a high priority for fishery management in the national park system." - Final Supplemental EIS on Elwha River and Ecosystem Restoration Implementation
Ken and Mary Campbell
Overview: Removal of two dams and restoration of the Elwha River will allow the return of anadromous fish stocks that once flourished in the river. To minimize impacts to the remaining fish in the river, all steps of dam removal must be approached with caution.
During the dam removal process, pulses of sediment will be released, causing short-term habitat degradation in the middle portion of the river. The temporary impact to fish will ultimately provide anadromous populations with spawning habitiat as the fine sediment previously held behind the dams redistributes down stream. View the Potential Range Map of salmonids after dam removal and ecosystem restoration.
Over the 20 to 30 years following dam removal, biologists predict that populations of anadromous stocks will rebound to historic numbers.
The restoration strategies developed for each Elwha salmonid are intended to be adaptive and flexible, and may change based on how the fish populations respond. If one strategy proves to be unsuccessful, biologists will use another in order to produce a healthy, naturally spawning population.
