A River Reawakened

Ten Years of Rewilding the Elwha Watershed

IN SEPTEMBER 2011, I stood on a river overlook with children from my daughter’s elementary school, all of us transfixed by a giant jackhammer pounding cement to rubble. Below us, a waterfall raged through the first notch carved in the Lower Elwha Dam, as dust rose in the September sunshine, drifting over Douglas fir and cedar crowns. Trees were the only spectators old enough to remember when the Elwha River ran free, a century earlier. The rest of us stood in awe, watching the world’s largest dam removal to date, feeling time start to spin in reverse.

I’ve spent a decade bearing witness to an unprecedented restoration experiment in Washington State. That September day committed me to unraveling the river’s story, while dam removal raised enough questions to keep scientists engaged for years to come.

The Elwha River begins in the Olympic Mountains, a rugged range encircled by ocean on three sides. Rivers radiate from the center of the Olympic Peninsula, short and steep, born from deep snowpack at the heart of the range. The Elwha River tumbles over four thousand feet in forty-five miles, from alpine meadows into rock canyons and flood plains, until it meets the sea in the Strait of Juan de Fuca.

When the first dam rose in 1911, it blocked the river just five miles upstream from the ocean. A second dam, constructed in Glines Canyon shortly before the creation of Olympic National Park, would operate within park boundaries for more than seven decades.

The beauty and diversity of Olympic National Park draws visitors from around the world. Many come to experience its “ancient groves” of old-growth forest. To me, this familiar landscape does not feel ancient. I imagine this is what the world was like when it was young. Freshly scrubbed by glaciers, with terrain like a restless teenager, prone to earthquakes and pulsing with life. The first time I took my daughter to a salmon creek during a fall run, we heard fish long before we could see them, splashing and slapping their tails in their raucous run upstream. Next came the stench of carcasses, salmon that had spawned and died, lining the bank. Finally, we caught a glimpse of the creek, where a cloud of pink salmon stirred an azure pool, circling below a stretch of rapids. Pink salmon arrive every other year, odd years only. When they return, they are the wildebeest of the Olympic Peninsula, a migration that once felt uncountable.

Wild salmon weave freshwater and saltwater ecosystems together, and rivers are the threads between those worlds. Impounding a river severs that connection in both directions. When dams were built without fish passage on the Elwha River, the most immediate impact was a barrier for anadromous fish.The river had legendary fish runs, attracting all five species of Pacific salmon, unusual in the region. The most iconic species was chinook, famous for its enormous size. Members of the Lower Elwha Klallam Tribe describe hundred-pound salmon, fish so big that children struggled to drag a single one home in a gunnysack.

A century after the first dam was constructed, these giant Chinook lived on in memory, with a remnant population supported by a hatchery. Pink salmon teetered on the edge of extirpation. Numbers of all anadromous fish in the Elwha, ten species including salmon, steelhead, and trout, had dwindled to a tiny fraction of the river’s past abundance. To visitors, the Elwha Valley felt wild, with much of the watershed protected by Olympic National Park. People who knew the river well heard the silence, and saw a system on the verge of collapse.

Dam removal began when my daughter was in kindergarten, after decades of advocacy by the Lower Elwha Klallam Tribe, environmental groups, and politicians. Now I trek into the valley with a teenager, hiking around washouts on a road we once drove. As we head upriver, a bobcat slinks across remaining pavement and disappears into a stand of bigleaf maple. Low mist hangs over the valley, as we orient ourselves in a changing landscape. When the upper dam came down, the river began to wander and tear at an access road that served a power station and the national park, carving unfamiliar channels with every flood.

 

 

 

We return each autumn to watch for salmon, the headline success story of dam removal, but this trip is timed for a different annual ritual. When the takedown of Elwha dams shifted from a crazy idea to imminent reality, revegetation specialists planned for the moment when water would drain away from two reservoirs, exposing land buried for a hundred years. An estimated 24 million cubic yards of sediment collected behind the dams, creating a challenge for ecologists who hoped to jump-start the process of plant succession. Their goal was to outrace invasive plant species in eight hundred acres laid bare by dewatering, and to set the stage for a future forest. Crews collected seeds from the Elwha Valley long before the dams came down, propagating native plants by the thousands. Volunteers transplanted more than 300,000 starts while teams prepared to scatter tons of natively sourced seed. As the final day approached, restoration ecologist Joshua Chenoweth added one last seed species to the master plan, despite limited supply: lupine, known for its nitrogen-fixing capacity.

Ten years later, the trail into the former reservoir, once known as Lake Mills, begins at an abandoned boat ramp. Our family pushes through a young forest of cottonwood and willow saplings, crowding the ramp where kayaks once launched. We call out as we enter a dense thicket of growth, hoping to alert black bears. The sweet smell of lupine reaches us before we emerge from the willows, into a sea of purple. The former reservoir is awash in lupine. These flowers are the first step in a slow transformation from stranded sediment to mature forest.

When salmon disappear, an entire watershed begins to change in subtle ways. Fish went missing from the whisper of trees, changing the inner workings of the forest. When salmon return to mountain streams, they transport marine-derived nutrients deep inland, feeding the forests that shade their spawning habitat. Scientists have shown the presence of ocean nutrients in the tissue of trees, many miles from shore. Migrating salmon attract wildlife, from otter to bear, who in turn help to distribute carcasses throughout the forest.

The single biggest question surrounding Elwha Dam removal was: Would the fish return, after a hundred-year absence? Fish numbers have increased steadily since the dams came down, and by 2019 Elwha Chinook numbered well over 7,000 adults. Mike McHenry, fisheries biologist at the Lower Elwha Klallam Tribe, says that 2019 numbers suggest a fivefold increase for juvenile Chinook, the first “strong signal” for natural chinook production in newly available habitat. He notes that river conditions began to stabilize in recent years. During initial salmon seasons after dam removal, turbid water and shifting channels posed a challenge for returning fish. During floods the river churned the color of chocolate milk, creating a sediment plume visible offshore, transforming the estuary and nearshore habitat. As these sediment pulses began to subside, the river and estuary came to life.

In addition to fish numbers, biologists are tracking the distribution and life histories of fish. A surge of summer steelhead in the upper river surprised scientists, who began to suspect that genetically similar rainbow trout were rediscovering anadromy—a capacity they had stilled for generations. Studies on Elwha steelhead continue, but initial findings suggest a remarkable story, one in which genetic potential outlasted many generations of entrapment. Anadromous species have ventured well beyond both former dam sites, with steelhead and Chinook traveling the farthest upstream. Throughout the watershed, scientists are observing diversity and changes in life strategy spurred by dam removal. Bull trout numbers have doubled, as they venture downstream into the estuary. Coho salmon rediscovered a lake previously walled off by dams, where their smolt are thriving.

The rewilding of the Elwha is a story of environmental justice, equal in scope to the scale of restoration. Salmon are at the heart of the Lower Elwha Klallam Tribe’s culture and economy, and tribal members were the first to protest the degradation of the river. As water rose behind the first dam, the reservoir inundated a site sacred to the tribe, believed to be the birthplace of the Klallam people. When the reservoir drained away, tribal members rediscovered the sacred place they’d lost a century earlier. This memory is now a physical place, visited by tribal members. The Lower Elwha Klallam Tribe continues to play a leading role in the restoration effort, working with Olympic National Park and numerous agencies to track and foster habitat recovery.

Tribal land encompasses the east side of the estuary, and for the first time in a century, the tribe is gaining, rather than losing land. Rivers move mountains to the sea. On a dammed river, sediment collects where water slows, filling reservoirs with gravel as the shoreline shrinks. Tribal elders remember harvesting shellfish near the estuary; however, cobblestones replaced this productive habitat over time, due to sediment trapped upstream. When the dams fell, these deposits began to flood downstream, rebuilding sandbars at the river’s mouth. The changing habitat quickly drew Dungeness crab and other species back to the near shore. Geologists tracking the growing shoreline have noted an unexpected benefit of dam removal: new sand deposits will help to buffer the shoreline against the impact of sea level rise.

Perhaps the most astonishing element of the Elwha restoration is how quickly ecosystem changes can be reversed. From sandbars stretching into the Strait of Juan de Fuca, to changes in wildlife upstream, the whole watershed has responded more rapidly than expected. With salmon numbers growing steadily, scientists are tracking species associated with migrating fish. One study considered American dippers, the West’s only aquatic songbird. As salmon returned to the Elwha, these charismatic birds were found to have marine-derived nutrients in their diet, which in turn made them more likely to stay in salmon-rich territory year-round, and to double-brood in one season. The Elwha experiment is revealing the role of salmon in countless other species, terrestrial and aquatic. Taken together, studies throughout the valley underscore a simple message: Everything is connected. And with connection, comes life.

On the eve of dam removal in 2011, Senator Bill Bradley traveled across the country to speak about “The great gift of the Elwha: hope.” This September marks a decade since speeches gave way to the hard work of dam removal and river restoration. Hope in 2021 can feel elusive, particularly amid a season of climate disruption. Yet the first ten years of the Elwha experiment have been breathtaking in speed and scope, a testament to the power of nature and potential for renewal.

Olympic National Park left the buttresses of Glines Canyon Dam intact, as a monument to what was, and what can be. Today the remains of the dam offer a dizzying view. Two hundred feet down, amid jagged rocks, a river of light threads the canyon. Wind moves through the notch of the former dam, channeled by the valley. With wind on my face, and white water coursing below, I feel something beyond hope: fleeting pure joy, mixed with gratitude for the chance to bear witness. I long to speak to the river that has roared and whispered in my head for so many years, to ask the river a question: Is this what the world was like when it was young?

  1. Thank you so much for the dramatic and violent taking away of the obstructive and “wrong” structure ; leading to the simple and wonderful quiet of what is right and good. Your photography and story are just really magnificent. Well done and thank you again. Blessings.

  2. When the dams were constructed in 1911, Jack Pike, the first game warden and perhaps the first conservationist on the Olympic Peninsula wrote a letter to the state of Washington telling them the dam would block spawning fish. He suggested fish ladders or fish bypasses be installed. Jack was apparently way ahead of his time. Jack Pike would later be elected Clallam County Sheriff in the 1920’s

  3. Drove up that winding dirt road in 2013, past the construction (destruction? unstruction?) gate up to the end. A busy yellow jacket nest kept us from hiking, but as an angler I was thrilled to be close to an activity so positive. Even more so now, eight hard years later. May we fill in more missing puzzle pieces! Thank you for a beautiful story.

  4. This article is the most hopeful writing I have read in a long, long time. My husband and I crossed the Elwha River this summer and it makes me so happy to know if it’s restoration for us all.

  5. This story is so uplifting and movingly told. It’s testimony to the immense value of environmental restoration, taking a lesson in perseverance from the salmon after a century of intervention. We can find our way back to the garden.

  6. In a brief week in 1994 I ventured up a road, across a dam, up to the head of a trail which I followed to a group of hot springs. On the way down I took a photo of a long lake behind that dam. I returned in 2014 to stand at the table in Sequim with a few others, carefully pulling tiny little fir trees out of tiny little potting cups, gathering compost from the big square bin in the corner and filling slightly larger potting cups, tucking the little firs in too. Such was the hold the Elwha took on me, a New Englander from 3000 miles away.

    Sadly I could not revisit those hot springs, the road was closed as the Glines Canyon dam area was not yet safe for tourists. But I got a peek through the tall trees further up of the mud flats which the dam removal had left behind.

    And I went to the mouth of the river and collected a quarter cup of the fine grey sand there to remember. It sits in the window at the top of my stairs here on Cape Cod to this day.

    Where I live we count herring. We worry about our artificial island drowning in the next 50 years, we restore a few “rivers” and mostly remove culverts and small dams built 100 years ago also to hold up roads. We fight the military’s lack of care for the huge aquifer that sits underneath the heart of our land mass. We plant oysters to combat the terrible destruction of septic systems which don’t block nitrogen from our wetlands, we labor to balance the pressure of human fecundity on our little piece of vulnerable land while ruefully acknowledging that we can’t have schools and roads and tourists if we don’t provide housing for all those humans.

    Not many of us over here are watching the Elwha experiment, but there are enough keeping track that when I tell of my short service in the greenhouse in Sequim some understand.

    It was a small contribution, a couple days in the sunshine. We all know that every pair of hands is necessary and appreciated, and that so many brains attached to pairs of hands must be corralled for more dams to be removed and more ecosystems restored.

    Thanks for your report. What joy!

  7. Jessica, I’m so moved. I rejoiced when the dam was removed and then again at the signs of restoration. Thank you for the eloquent expression of pure life. The free-flowing river speaks of release, freedom, and joy through your words and the photos and videos. It’s a celebration that all can participate in.

  8. Nowadays it’s hard to feel hope when you see the bad things that humans are doing to nature. This reading renewed my spirit and calmed my anxiety. I feel the urgency of getting involved in local environmental issues in my area. I been waiting to act for the right time. The right time is NOW.

  9. I am so grateful for the work done by those who stood for and spoke for this river~~as well as the work of Jessica Plumb. Watching the film gives me so much joy and hope for what we can do to help our dear Planet.

  10. Living in a tiny strip of land between high mountains and the Arabian Sea, in Kerala, in the south western corner of India, with more than 60 large dams that have killed most of our rivers, this dam removal gives me Great Hope and the guts to pray for the liberation of the Rivers of this ecologically fragile tropical rainforest land. The mountain streams of Kerala, most of which originating from the Rainforests of the steep Western Ghats mountains have not been able to stand the assault of large dams. We are still fighting against many more dams proposed for both irrigation and hydro electric power generation. Thank you for documenting this ambitious and risky process of breaking dams to free a River and save her denizens with magnificent pictures and heartfelt language. All my deep appreciation and prayers for such a venture to begin in our country too.

  11. Stunning essay on a powerful complex place and historical story, with a future. thank you for posting.

  12. I was thrilled to read your story. For so long I dreaded the possibility that the damage done by the dams was irreversible in some important ways. I hope the future of the Elian River includes an productive equilibrium among the returning species.
    Thank you so much for this story.
