Restoration along Oregon’s Willamette River Opens up New Opportunities for Business and Wildlife

This is a post by the NOAA Restoration Center’s Lauren Senkyr.

Salmon, mink, bald eagles, and other wildlife should be lining up to claim a spot among the lush new habitat freshly built along Oregon’s Willamette River. There, a few miles downstream from the heart of Portland, construction at the Alder Creek Restoration Project is coming to a close. Which means the reshaped riverbanks and restored wetlands are open for their new inhabitants to move in.

This 52 acre project is the first habitat restoration effort for the Portland Harbor Superfund Site and has been implemented specifically to benefit fish and wildlife affected by years of industrial contamination in the harbor.

Salmon, lamprey, osprey, bald eagle, mink, and others will now enjoy sandy beaches, native vegetation, and large pieces of wood to perch on or hide underneath. These features replace the saw mill, parking lots, and other structures present on the property before it was purchased by Wildlands, Inc. Chinook salmon and osprey have already been seen seeking refuge and searching for food in the newly constructed habitat.

Wildlands is a business that intends to sell ecological “credits” from this restoration project. The credits that the Alder Creek project generates are available for purchase to resolve the liability of those who discharged oil or hazardous substances into Portland Harbor.

Construction on the restoration site began in the summer of 2014. First, hundreds of thousands of yards of wood chips were removed from the site of a former saw mill and several buildings were demolished. A channel was excavated on the western portion of the site, which was continued through the eastern half of the site when construction resumed in 2015.

Also this year, efforts involved removing invasive vegetation, planting native vegetation, and installing large wood structures along the channel to create ideal places for young fish to rest, feed, and hide from predators.

After a final breach of the earthen dam dividing the restoration site this September, water now flows across the newly restored area. Once additional planting is completed this winter, the project will officially be “open for business,” although some entrepreneurial wildlife are already getting a head start.

Expanding a Washington River’s Floodplain to Protect Northwest Salmon and Communities

From the edge of the Emmons Glacier on Washington’s tallest peak, the scenic White River winds down the mountain, through forest, and joins the Puyallup River before finally reaching the sea at an industrial port in the city of Tacoma.

Here, in the salty waters of Puget Sound’s Commencement Bay, iconic Northwest salmon start their own journey in reverse. These fish head up waterways toward Mt. Rainier, where they were born, where they will spawn, and where they will die.

Recently NOAA and our partners announced a restoration project that will improve the floodplain of the White River for migrating fish. One of Mt. Rainier’s largest rivers and one of Puget Sound’s most important areas for imperiled salmon and steelhead, the White River has been re-routed and re-engineered for longer than a century.

This restoration was made possible by the U.S. Department of Justice’s August 6, 2015 announcement that more than 56 parties have agreed to restore key salmon habitat on the White River. The settlement will also permanently preserve intertidal habitat in Wheeler Osgood Waterway in Tacoma’s Commencement Bay. Fulfilling these restoration projects will resolve their liability for natural resource damages caused by releasing hazardous substances into the bay’s Thea Foss and Wheeler-Osgood Waterways.

One restoration project will set back levees on the White River and widen its previously re-engineered floodplain. This will create better habitat for migrating fish to feed, rest, and spawn, as well as offer improved flood protection for nearby homes and businesses. (NOAA)

The White River project will not only help protect the region’s salmon but also its communities as it sets back levees and widens the floodplain. By restoring fish habitat and providing slower-moving side channels on the river, the proposed project will reopen 121 acres of historic floodplain around the river. Allowing floodwaters more room to flow, this project will also help reduce the risk of flood damage for more than 200 nearby homes and businesses.

The latest project will continue a long legacy of ensuring those responsible for releasing hazardous materials—from industrial chemicals such as PCBs to heavy metals including lead and zinc—into Commencement Bay are held accountable for restoring public natural resources. This is the 20th natural resources settlement related to pollution in Commencement Bay, which is the industrial heart of Tacoma. Through these settlements, more than 350 acres of Puget Sound habitat will have been restored, offsetting impacts to salmon, other fish, and wildlife harmed by pollution in the bay.

Those responsible for the pollution will monitor and adaptively manage the project under a 10-year plan that ensures at least 32.5 acres of the restoration site are inundated by the river and thus accessible to fish. They also will pay more than $1 million toward the natural resource trustees’—including NOAA’s—assessment, oversight and the long-term stewardship costs of maintaining the project over the next 100 years and beyond.

From Building B-17 Bombers to Building Habitat for Fish: The Reshaping of an Industrial Seattle River

Imagine living in as little as two percent of your home and trying to live a normal life. That might leave you with something the size of a half bathroom.

Now imagine it’s a dirty half bathroom that hasn’t been cleaned in years.

Gross, right? As Muckleshoot tribal member Louie Ungaro recently pointed out, that has been roughly the situation for young Chinook salmon and Steelhead trout for several decades as they pass through the Lower Duwamish River in south Seattle, Washington.

Salmon and Steelhead trout, born in freshwater streams and creeks in Washington forests, have to make their way to the Puget Sound and then the ocean through the Duwamish River. However, this section of river has been heavily industrialized and lacks the clean waters, fallen trees, huge boulders, and meandering side channels that would represent a spacious, healthy home for young fish.

Chair of his tribe’s fish commission, Ungaro sent a reminder that the health of this river and his tribe, which has a long history of fishing on the Duwamish and nearby rivers, are closely tied. “We’re no different than this river,” he implored. Yet he was encouraged by the Boeing Company’s recent cleanup and restoration of fish habitat along this Superfund site, a move that he hopes is “just a start.”

The Pace—and Price—of Industry

Starting as far back as the 1870s and stretching well into the twentieth century, the Lower Duwamish River was transformed by people as the burgeoning city of Seattle grew. The river was straightened and dredged, its banks cleared and hardened. Factories and other development lined its banks, while industrial pollution—particularly PCBs—poured into its waters.

More than 40 organizations are potentially responsible for this long-ago pollution that still haunts the river and the fish, birds, and wildlife that call it home. Yet most of those organizations have dragged their feet in cleaning it up and restoring the impacted lands and waters. However, the Boeing Company, a longtime resident of the Lower Duwamish River, has stepped up to collaborate in remaking the river.

The former site of Boeing’s Plant 2 is now home to five acres of marsh and riverbank habitat, creating a much friendlier shoreline for fish and other wildlife. Protective fencing and ropes attempt to exclude geese from eating the young plants. (NOAA)

Boeing’s history there began in 1936 when it set up shop along 28 acres of the Duwamish. Here, the airplane manufacturer constructed a sprawling building known as Plant 2 where it—with the help of the women nicknamed “Rosie the Riveters”—would eventually assemble 7,000 B-17 bombers for the U.S. government during World War II. The Army Corps of Engineers even took pains to hide this factory from foreign spies by camouflaging its roof “to resemble a hillside neighborhood dotted with homes and trees,” according to Boeing.

But like many of its neighbors along the Duwamish, Boeing’s history left a mark on the river. At the end of 2011, Boeing tore down the aging Plant 2 to prepare for cleanup and restoration along the Duwamish. Working with the City of Seattle, Port of Seattle, and King County, Boeing has already removed the equivalent of thousands of railcars of contaminated sediment from the river bottom and is replacing it with clean sand.

From Rosie the Riveter to Rosie the Restorer

By 2013, a hundred years after the Army Corps of Engineers reshaped this section of the Duwamish from a nine mile estuary into a five mile industrial channel, Boeing had finished its latest transformation of the shoreline. It planted more than 170,000 native wetland plants and grasses here, which are interspersed with large piles of wood anchored to the shore.

Five acres of marsh and riverbank vegetation now line its shores, providing food, shelter, and calmer side channels for young fish to rest and grow as they transition from freshwater to the salty ocean.

Protecting the newly restored shoreline, out of sight to the left, from Canada geese is a challenge to getting the young wetland plants established. Behind the geese, the artificial, rocky shoreline is a stark difference from the adjacent restored portion. (NOAA)

Now the challenge is to keep the Canada geese from eating all of the tender young plants before they have the chance to establish themselves. That is why protective ropes and fencing surround the restoration sites.

Already, biologists are beginning to see a change in the composition of the birds frequenting this portion of the river. Rather than the crows, starlings, and gulls typically associated with areas colonized by humans, birds such as herons and mergansers, a fish-eating duck, are showing up at the restoration sites. Those birds like to eat fish, which offers hope that fish such as salmon and trout are starting to make a comeback as well.

Of course, these efforts are only the beginning. Through the Natural Resource Damage Assessment process, NOAA looks forward to working with other responsible organizations along the Duwamish River to continue restoring its health, both for people and nature now and in the future.

An Oiled River Restored: Salmon Return to Alaskan Stream to Spawn

Last summer NOAA’s Damage Assessment, Remediation, and Restoration Program (DARRP) traveled to the remote Adak Island in Alaska to help salmon return to their historical home by removing barriers from Helmet Creek. We headed back out this September to see how things were going. As you can see from our photos, the salmon seem to be big fans of our 2013 restoration work.

Our mission this September was to monitor the success of these habitat restoration efforts and make sure no new problems have occurred since then. A survey of the creek quickly showed that salmon are now pushing as far upstream as naturally possibly, allowing them to enter formerly impassable areas with ease. Now the only thing preventing salmon from continuing further upstream is a natural waterfall.

During this visit, Helmet Creek was teaming with Pink and Chum salmon. One walk of the roughly two kilometer (one and a quarter mile) portion of stream resulted in our counting more than 600 adult salmon, over half of which were beyond the areas where we had removed fish passage barriers.

Before we stepped in to restore Helmet Creek, salmon were hitting a number of man-made obstacles preventing them from getting to the natural areas where they reproduce, known as their spawning grounds. In 2013 we removed these fish barriers, pulling out a number of 55-gallon drums and grates, all of which were impeding the salmon’s ability to swim upstream and covering their spawning grounds.

While seeing all these active fish is exciting, we are also looking forward to the ways these fish will continue helping the environment after they die. As salmon are now able to travel further upstream, they will take valuable nutrients with them too. After spawning, these pink and chum salmon will die and their decaying carcasses will return extremely valuable nutrients to the stream habitat and surrounding area. These nutrients will provide benefits to resident trout, vegetation, and birds nearby.

Restoration of Helmet Creek resulted from our work to restore the environment after a 2010 oil spill on the remote Adak Island, part of Alaska’s Aleutian Island chain. Through DARRP, we worked with our partners to determine how the environment was injured and how best to restore habitat. You can read more about our efforts in—and the unusual challenges of—assessing these environmental impacts to salmon and Helmet Creek.

A River Reborn: Restoring Salmon Habitat along Seattle’s Duwamish River

Just south of Seattle, the airplane manufacturer Boeing Company has created one of the largest habitat restoration projects on the Lower Duwamish River. Boeing worked with NOAA and our partners under a Natural Resource Damage Assessment to restore habitat for fish, shorebirds, and wildlife harmed by historical industrial activities on this heavily used urban river. We documented and celebrated this work in a short video.

What Kind of Restoration?

In this video, you can learn about the restoration techniques used in the project and how they will benefit the communities of people, fish, and wildlife of the Duwamish River. The restoration project included activities such as:

  • Reshaping the shoreline and adding 170,000 native plants and large woody debris, which provide areas where young salmon can seek refuge from predators in the river.
  • Creating 2 acres of wetlands to create a resting area for migrating salmon.
  • Transforming more than a half mile of former industrial waterfront back into natural shoreline.

Watch the video:

Why Does this River Need Restoring?

In 1913, the U.S. Army Corps of Engineers excavated and straightened the Duwamish River to expand Seattle’s commercial navigation, removing more than 20 million cubic yards of mud and sand and opening the area to heavy industry. But development on this waterway stretches back to the 1870s.

Ninety-seven percent of the original habitat for salmon—including marsh, mudflats, and toppled trees along multiple meandering channels— was lost when they transformed a 9-mile estuary into a 5-mile industrial channel.

As damaged and polluted as the Lower Duwamish Waterway is today, the habitat here is crucial to ensuring the survival and recovery of threatened fish species, including the Puget Sound Chinook and Puget Sound Steelhead. These young fish have to spend time in this part of the Duwamish River, which is a Superfund Site, as they transition from the river’s freshwater to the saltwater of the Puget Sound and Pacific Ocean. Creating more welcoming habitat for these fish gives them places to find food and escape from predators.

Fortunately, this restored waterfront outside of a former Boeing plant will be maintained for all time, and further cleanup and restoration of the river is in various stages as well.

UPDATE 6/17/2014: On June 17, 2014, Boeing hosted a celebration on the newly restored banks of the Lower Duwamish River to recognize the partners who helped make the restoration a reality. Speakers at the event included NOAA, Boeing, the Muckleshoot Tribe, and a local community group. This also gave us the opportunity to share the video “A River Reborn,” which was well received.

Watch Art Explain What Kind of Habitat Young Salmon Need to Thrive

Illustration from video of two salmon swimming by tree roots.What do young salmon need to grow into the kind of big, healthy adult salmon enjoyed by people as well as bears, seals, and other wildlife? A recent collaboration between NOAA Fisheries and the Pacific Northwest College of Arts makes the answer come to life in a beautiful animation by artists Beryl Allee and John Summerson.

Watch the intersection of art and science as we follow young salmon happily swimming through the cool, shallow waters along a shore. We see the bits of wood, tangled tree roots, and scattered rocks that provide these fish with both insects to eat and protection from predators.

But what happens when a home or business shows up along the water’s edge? How do people remake the shoreline? What kind of environment does this create for those same little salmon?

NOAA partnered with the Pacific Northwest College of Arts to create this moving and educational tool to raise awareness among waterfront landowners and the general public about how the decisions we make affect endangered salmon. In particular, NOAA wanted to address the practice of “armoring,” or using physical structures such as rocks and concrete to protect shorelines from coastal erosion. As we can see in the animation, armored shorelines do not make for happy, healthy young salmon.

Illustration from animation of a sad fish and an armored shoreline.

However, alternatives to armoring shorelines with hard materials are emerging. They include using plants and organic materials to stabilize the shores while also preserving or creating the kind of habitat young salmon need.

Creating better habitat for fish is often the goal of NOAA’s Damage Assessment, Remediation, and Restoration Program (DARRP). When we determine that fish were harmed after an oil spill or hazardous chemical release, we, with the help of a range of partners and the public, identify and implement restoration projects to make up for this harm.

Take a look at a few examples in which we built better habitat for salmon:

Beaver Creek, Oregon

A tanker truck carrying gasoline overturned on scenic Highway 26 through central Oregon in 1999, spilling 5,000 gallons of gasoline into Beaver Butte Creek and impacting steelhead trout and Chinook salmon. Working with the Confederated Tribes of the Warm Springs Reservation of Oregon and other partners, we have helped implement five restoration projects. They range from adding large wood to stream banks to provide fish habitat to installing two beaver dam–mimicking structures to improve water quality.

White River, Washington

In 2006 a system failure sent 18,000 gallons of diesel into creeks and wetlands important to endangered Chinook salmon around Washington’s White River. To improve and expand habitat for these salmon, NOAA and our partners removed roadfill and added large pieces of wood (“logjams”) along the edges of the nearby Greenwater River. This restoration project will help slow and redirect the river’s straight, fast-moving currents, creating deep pools for salmon to feed and hide from predators and allowing some of the river water to overflow into slower, shallower tributaries perfect for spawning salmon.

Adak, Alaska

On the remote island of Adak in Alaska’s Aleutian Islands, a tanker overfilled an underground storage tank in 2010. This resulted in up to 142,800 gallons of diesel eventually flowing into the nearby salmon stream, Helmet Creek. Pink salmon and Dolly Varden trout were particularly affected. In 2013 NOAA and our partners restored fish passage to the creek, improved habitat and water quality, made stream flow and channel improvements, and removed at least a dozen 55-gallon drums from the creek bed and banks.

NOAA and Partners Invest in an Innovative New Stewardship Program for Washington’s Commencement Bay

Last week, NOAA and partners awarded $4.9 million to EarthCorps for long-term stewardship of restoration sites in Commencement Bay near Tacoma, Washington. The Commencement Bay Stewardship Collaborative is part of a larger investment that will conserve habitat for fish and wildlife and give local urban communities access to the shoreline.

EarthCorps, which was competitively selected for this funding, is a non-profit organization that trains environmental leaders through local service projects.

The funding will support planning, restoration, monitoring, and maintenance at 17 sites across the Bay. These sites were restored over the past 20 years as part of the ongoing Commencement Bay natural resource damage assessment (NRDA) case. This is the first time that a third party has received funding to launch a comprehensive stewardship program as part of a NRDA case. We hope it will become a model of stewardship for future cases.

Commencement Bay is the harbor for Tacoma, Washington, at the southern end of Puget Sound. Many of the waterways leading into the Bay—which provide habitat for salmon, steelhead, and other fish—have been polluted by industrial and commercial activities. NOAA and other federal, state, and tribal partners have been working for decades to address the contamination and restore damaged habitat.

One of the sites that EarthCorps will maintain is the Sha Dadx project on the bank of the Puyallup River. The lower Puyallup River was straightened in the early 20th century, leaving little off-channel habitat—which juvenile salmon use for rearing and foraging. The project reconnected the river to a curve that had been cut off by levees. This restored 20 acres of off-channel habitat, and fish and wildlife are using the site.

Most of the parties responsible for the contamination have settled and begun implementing restoration. NOAA and its partners are evaluating options for pursuing parties that haven’t settled yet. As new sites are added, stewardship funds will be secured at settlement and likely added to the overall long-term effort.
