Historic Anadromous Fish Runs in the Elwha
 
The Elwha River
Scott Church
After restoration of the Elwha River is complete, the pristine waters have the potential of supplying optimum habitat for the thousands of salmonids that return each year. 

Historical Range:
Before construction of the dams, native fish used the Elwha River and its diverse habitats for spawning. The inaccessibility created by the dams has seriously diminished all 10 native Elwha River anadromous fish runs, including all five types of Pacific salmon, as well as native char (bull trout and dolly varden), winter and summer-run steelhead, and sea-run cutthroat trout. In addition, sediment has been caught behind the dams, preventing gravel and debris from entering the lower 5 miles of the river, and thus rendering the available reaches practically unsuitable for the spawning of particular populations of native fish.

Did You Know?
That endemic Olympic snow moles are scurrying beneath this blanket of snow? Olympic National Park's Hurricane Ridge is blanketed with over ten feet of snow for most of the winter, providing water for summer and protection for snow moles in winter.
