In a few days the Elwha dam which has blocked the Elwha River for nearly a century will stop producing power in preparation for drawing down the reservoir behind it. This is among the first steps to restoring the Elwha river to its natural condition. Two rivers block the river neither of which having fish ladders.
The Elwha river is unique because most of its drainage is within the horseshoe shaped mountains that define Olympic National Park. Though only about 50 miles long, its appears larger because the Western flank of the Olympic mountains receives nearly 200 inches of rain per year. The Eastern side gets much less rain but on average the valley gets tremendous amounts of rainfall. Nearly 20 years ago I hiked the interior including trails along the Elwha river. It's a wild river surrounded by huge stands of virgin West Ceder and roaming herds of Roosevelt Elk and at least one pair of fish stealing raccoons who outwitted me. There are also cougar, which I didn't see. The black bears were much higher enjoying the sub-alpine summer huckleberries. (If you have a week off and set of strong legs I highly recommend it--almost no one gets into the upper valley). One of the most interesting parts of the restoration will be the change to the upper river once salmon return and add their biomass to the food chain. More bear, bald eagle are expected in the valley spreading their dun and increasing the fertility of the river's flood plain. I think the changes in the valley will rival those we've seen in Yellowstone with the return of wolves.
