Stormwater projects in Silverdale offer hope for a degraded Clear Creek

Detailed planning and design, followed by thoughtful construction projects, have begun to tame the stormwater menace in Clear Creek, an important salmon stream that runs through Silverdale in Central Kitsap.

Stormwater has been identified as the greatest pollution threat to Puget Sound. In Kitsap County, many folks believed that the dense development pattern in and around Silverdale has doomed Clear Creek to functioning as a large drainage ditch for runoff into Dyes Inlet.

But reducing stormwater pollution is not beyond the reach of human innovation, as I learned this week on a tour of new and planned stormwater facilities in the Clear Creek drainage area. The trick is to filter the stormwater by any means practical, according to Chris May, director of Kitsap County’s Stormwater Division and a key player in the multi-agency Clean Water Kitsap program.

Projects in and around Silverdale range from large regional ponds of several acres to small filtration devices fitted into confined spaces around homes and along roadways.

On the small side, below-grade planter boxes have been installed along Silverdale Way, Bucklin Hill Road and Ridgetop Boulevard to filter runoff flowing into storm drains. One can spot these innovative devices by looking for the protective “cages” that keep people from trampling the young plants.

Rain gardens, another filtering technique, can be installed in people’s yards, along a roadway or anyplace where they can capture a relatively small volume of stormwater. Several housing developments, including Shadow Glen north of Silverdale, have been given the name “green streets” for infiltrating stormwater into the ground rather than passing it into Clear Creek.

On a somewhat larger scale, one strategy widely used in Kitsap County is to reconstruct stormwater ponds in old developments. Old stormwater facilities typically contain a single open pond surrounded by a chain link fence. Such ponds can be enlarged and divided into sections, known as cells. Contaminated sediments settle out in the first cell before the water passes into the second cell, and so on.

The old “stormwater prisons,” as Chris May calls them, may slow down the flow of water, but they have limited abilities to reduce pollutants. New ponds are built more like miniature wetlands, where vegetation helps to settle and absorb the toxic runoff.

Often the edges of an old pond can be sloped more gradually than what was done in the original construction. That reduces the drowning hazard of the old ponds and allows the chain link fencing to be eliminated. Many of the new ponds are now surrounded by a split-rail fence.

Tuesday’s tour, which included public officials and interested citizens, stopped at the Quail Hollow development north of Silverdale, where an old pond was turned into a new wetland with high-tech functions — including a metered discharge and solar-powered aerator. The aerator boosts oxygen levels to keep the water from becoming stagnant during low-flow periods.

A walking trail, which loops around Quail Hollow Regional Pond, will eventually connect to the Clear Creek Trail. As people on the tour walked around the pond, a great blue heron gazed out from the middle of the stormwater wetland.

Amenities like the walking trail and improved wildlife habitat make the new stormwater ponds more appealing to nearby residents, Chris noted.

“I’m told by the birders that this is a nice place to watch birds,” he said.

The next “stormwater park” to be developed will be at Whispering Firs north of Silverdale. It will be another natural pond surrounded by a split-rail fence with a trail eventually connecting to the local trail system.

Another multi-celled stormwater system was constructed on vacant land behind two shopping centers in Silverdale’s commercial area. The project, adjacent to the Clear Creek Trail on the west side of the stream, captures water from the adjacent parking lots and includes a trail connection between T.J. Maxx and Ross Dress for Less.

Chris also showed the group several large culverts, which replaced small ones that had impeded the passage of salmon. One culvert on Sunde Road was replaced with a foot bridge for students going to and from Clear Creek School. Neighbors supported the project, because it eliminated a road that was used as a shortcut by motorists passing through the neighborhood on the way to the school, Chris said.

“A question you should always ask,” he said, “is ‘Do you really need this road?’”

Eliminating the road also created a safe place for people to watch salmon swimming in Clear Creek and a place for students to release salmon as part of the Salmon in the Classroom program.

Tuesday’s tour ended at the Clear Creek floodplain project, which I discussed in Water Ways last September. That $3-million project involved the removal of 30,000 cubic yards of material across 21 acres, including the former Schold Farm on the west side of Silverdale Way and the Markwick property on the east side. The project is designed to slow the flow of water downstream while providing a rich habitat for fish and wildlife.

Rocky Hrachovec, principal engineer for Natural Systems Design, said the key to restoration projects is to understand the history of an area, including the former elevations of the stream at various locations.

“It’s important to understand what was here before and how close we can get to that,” he said. “For salmon, you want some places with shallow, fast water and other places with deeper, slower water.”

During heavy rains, Clear Creek is expected to spill over its banks within the restored floodplain and even shift the location of its streambed over time. Logjams have been carefully located to create hard points to confine the flow within the property, he said. The restored floodplain will essentially store excess stormwater and release it slowly back into Clear Creek.

Andy Nelson, director of Kitsap County Public Works, said the efforts to restore Clear Creek did not come about by accident.

“Everything we have seen here today is the result of a thought process, a vision,” Andy said, commending Chris May for his leadership and the hiring of innovative design teams and construction firms.

Andy also gave credit to other innovators, including those who developed a nursery to produce the wetland plants used in many of the projects and those who organized volunteers to safely capture fish so that they wouldn’t be killed during construction. He also commended many others — from volunteers to construction companies to elected officials.

Clear Creek is not the only watershed in Kitsap County where stormwater is being tamed by removing its powers of pollution and erosion, but it stands as an example of what can be done in heavily urbanized watersheds. While habitat loss along the stream cannot be easily replaced, the various stormwater projects go a long way to restoring the health of Clear Creek.

What comes next under water-quality standards imposed by the EPA?

The Environmental Protection Agency approved new water-quality standards for Washington state this week, overriding a plan approved by Gov. Jay Inslee and the state Department of Ecology.

It was a rare posture for the EPA. Now the state will be pressured to appeal the EPA standards to federal court. Cities and counties as well as some industrial organizations are clearly unhappy with the EPA’s action, while environmental and tribal representatives got most of what they wanted.

The basic structure of polychlorinated biphenyls, where the number and location of chlorine atoms can vary.
The basic structure of polychlorinated biphenyls, where the number and location of chlorine atoms can vary.

The EPA action is especially unusual, given that this state is known for some of the strongest environmental regulations in the country. After much dispute, Ecology finally agreed to much higher fish-consumption rates without increasing the cancer-risk rate, leading to more stringent standards for many of the chemicals. But Ecology had its own ideas for the most troublesome compounds with implications for human health. They include polychlorinated biphenyls (PCBs), arsenic and mercury. For background, see Water Ways, Oct. 18, 2015.

Some news reports I saw this week said EPA’s action will lead to salmon that are safer to eat. But that’s not at all certain, and opponents say it is unlikely that the revised limits on chemical pollution will have any practical effect on compounds that affect human health.

Understanding how rogue chemicals affect people and marine life

Scientists are just beginning to understand the profound impact that synthetic chemicals are having on humans and other animals in the Puget Sound region.

My latest story for the Encyclopedia of Puget Sound addresses so-called chemicals of emerging concern. Please check out “Concerns rise over rogue chemicals in the environment.”

While talking to researchers and investigating a variety of biologically active compounds, I began to realize the complexity of the body’s internal chemistry. I thought I knew something about the endocrine system, but I never fully considered how one hormone can trigger responses in multiple organs, including the release of additional hormones, even creating feedback loops.

Annual salmon watching is now on the fall agenda

Early and continuing rains in October have increased streamflows and brought coho and chum salmon into their spawning territories ahead of schedule this year.

I was out and about today, taking a look at some of the streams in Central Kitsap. I couldn’t pass up the chance to enjoy the sunny and warm weather, and I was pleased to encounter a lot of other folks doing the same thing. Adults of all ages, some with children, were out looking for the elusive salmon. That’s not something I ever saw 10 years ago while making my rounds to public salmon-viewing spots.

I believe the growing interest in salmon may result from ongoing promotions of salmon watching by governmental and volunteer organizations, as well as the news media. Why shouldn’t we go out to watch salmon swimming upstream and possibly, if one is lucky, catch a glimpse of spawning behaviors? After all, we live in one of the best areas for this enjoyable pastime.

Amusing Monday: The evolution and danger of packaging drinks by six

When I was a young child, we didn’t have to worry about wildlife getting strangled by six-pack rings, because these plastic binders for cans had not been invented yet. I was 9 years old in 1961 when this simple, convenient form of packaging was invented, so I clearly remember the transition. (See Hi-Cone history.)

At the time, nobody predicted the conservation consternation that would be created by such a simple piece of plastic. During the 1970s and up to present, pictures of entrapped birds and other sea creatures became common, suggesting that we at least cut the plastic to save the animals. The first video provides a story of potential revenge.

Before the invention of six-pack rings, people bought soft drinks and beer in cardboard packages, which sort of wrapped around the cans. Pabst Blue Ribbon may have been the first beer sold in cardboard cartons (second video), although Coca Cola may have started the phase. The Coke company claims to be the first to take its bottles out of wooden crates and begin offering cardboard packaging for consumers as early as 1923.

Extensive floodplain restoration brings new hope to Clear Creek

A giant piece of a cedar log stands erect in a barren landscape north of Silverdale, where a new channel for Clear Creek stands ready to receive water.

Well, maybe this channel won’t be entirely new. Designers working to restore this portion of Clear Creek studied old maps. They tried to align the new man-made channel to the meandering stream that existed 150 years ago, before farmers diverted the creek around their fields.

During excavation, workers uncovered buried gravel — remnants of the old streambed — along with chunks of cedar that had lain along the edge of the stream. Buried and cut off from oxygen, these pieces of wood survived for decades underground, while cattle grazed in the fields above.

Workers excavating for the new channel used their heavy equipment to pull out what remained of a great cedar log. They stood the log vertical and buried one end in the ground — a monument to the past and future of Clear Creek.

Chris May, manager of Kitsap County’s stormwater program, showed me the new channel this week. He said it was rewarding to uncover some buried history and realize that the stream would be restored in roughly the same place.

“We found the old channel,” Chris told me, pointing to a deposit of gravel. “We are pretty confident that we got it right.”

This $3-million project has been conceived and designed as much more than a stream-restoration project. The elevations of the land around the stream have been carefully planned so that high flows will spill into side channels and backwater pools. That should reduce flooding in Silverdale and help stabilize the high and low flows seen in Clear Creek.

The engineers did not calculate the reduced frequency of flooding, but floodwater storage is calculated to be 18.4 acre-feet, the equivalent of a foot of water spread over 18.4 acres or 29,700 cubic yards or 6 million gallons.

In all, about 30,000 cubic yards of material have been removed across 21 acres, including the former Schold Farm on the west side of Silverdale Way and the Markwick property on the east side. Native wetland vegetation will be planted along the stream and in low areas throughout the property. Upland areas will be planted with natural forest vegetation.

The topsoil, which contained invasive plants such as reed canarygrass, was hauled away and buried beneath other excavated soils to form a big mound between the new floodplain and Highway 3. That area will be planted with a mixture of native trees.

Plans call for removal of 1,500 feet of an existing road with upgrades to two aging culverts. Adding meanders to the straightened channel will create 500 feet of new streambed that should be suitable for salmon spawning.

Plans call for adding 334 pieces large woody debris, such as logs and root wads to the stream. Some of that wood will be formed into structures and engineered logjams to help form pools and gravel bars.

“This will be one of the first streams to meet the Fox and Bolton numbers,” Chris told me, referring to studies by Martin Fox and Susan Bolton of the University of Washington. The two researchers studied natural streams and calculated the amount of woody debris of various kinds needed to simulate natural conditions, all based on the size of a stream. (Review North American Journal of Fisheries Management.)

The elevations on the property were also designed so that high areas on opposite sides of the stream would be in close proximity in several locations.

“Beaver will pick that spot,” Chris said, pointing to one location where the stream channel was squeezed by elevated banks on each side. “We want to encourage beaver to come in here.”

Beaver ponds will increase the floodwater storage capacity of the new floodplain and provide important habitat for coho salmon, which spend a year in freshwater and need places to withstand both high and low flows. Because the county owns the flooded property, there won’t be any complaints about damage from beavers, Chris noted.

Clear Creek Trail (PDF 390 kb), which begins on the shore of Dyes Inlet, will be routed along the higher elevations as the trail winds through the property. Three new bridges will provide vantage points to watch salmon after vegetation obscures other viewing areas from the trail. Viewing platforms, as seen along other parts of Clear Creek Trail, were not included in this project but could be subject to further discussions.

Count me among the many people — experts, volunteers and users of Clear Creek Trail — who are eager to see how nature responds when water (now diverted) returns to the new stream channel. For decades, the lack of good habitat has constrained the salmon population in Clear Creek. The stream still has problems related to its highly developed watershed. But now a series of restoration projects is providing hope for increased coho and chum salmon and possibly steelhead trout as well as numerous other aquatic species.

In a story in the Kitsap Sun, Reporter Tristan Baurick described work this week on the Markwick property, where fish were removed in preparation for final channel excavation.

Here are some details (including photos) of various Clear Creek projects, as described in the state’s Habitat Work Schedule for restoration projects:

Washington Department of Ecology provided $2 million for the project. Kitsap County’s stormwater and roads programs each provided $500,000.

A difference between chum and coho salmon may be in their blood

On the outside, chum and coho salmon don’t seem all that different from one another, not when you consider the variety of fish in Puget Sound — from herring to halibut along with dozens of other odd-looking creatures (EoPS).

But we know that if you place coho in stormwater taken from a heavily traveled roadway, the coho are likely to die within hours. But if you do the same thing with chum, these hardy fish will barely notice the difference.

Researchers began to observe the varying effects of pollution on different species of salmon years ago. In 2006, I reported on studies by researcher Nat Scholz of the National Marine Fisheries Service, who discovered that coho would swim into Seattle’s heavily polluted creeks to spawn, but they wouldn’t get very far. Within hours, they would become disoriented, then keel over and die. (Kitsap Sun, June 10, 2006)

Later, Jenifer McIntyre, a researcher with Washington State University, collaborated with Scholz to refine the studies, exposing adult coho and later young coho to stormwater under controlled conditions. Much of that work was done at the Suquamish Tribe’s Grover’s Creek Hatchery in North Kitsap. The researchers also measured the physiological effects of pollution on zebrafish embryos during their early stages of development.

Working at the Washington Stormwater Center in Puyallup, Jen made a remarkable discovery that has dramatically changed people’s thinking about stormwater treatment. She found that if you run the most heavily polluted stormwater through a soil medium containing compost, the water will no longer have a noticeable effect on the sensitive coho. Rain gardens really do work.

Jen’s findings and related stormwater issues were described in a story I wrote two years ago for the Kitsap Sun, “Stormwater solutions key in fight for Puget Sound.” The story is part of a two-year project we called “Taking the Pulse of Puget Sound.”

Now, Jen, who recently joined the faculty of WSU, is beginning a new phase of her research, probing deeper into the physiological responses of coho salmon when exposed to polluted stormwater. She told me that the varying responses of coho and chum offer clues about where to look for problems.

“It is very interesting,” she said. “As biologists, we understand that there is variability among species. But we would expect, at least among salmon, that things would be pretty much the same.”

Researchers in Japan have discovered that different kinds of fish have different subunits in their hemoglobin, which are the proteins in red blood cells that carry oxygen to the vital organs. Since coho and other salmon may have different forms of hemoglobin, oxygen transport in the blood is a good place to start this investigation, she said.

From there, the issues of blood chemistry get a little technical, but the ability of red blood cells to carry oxygen can depend not only on the form of hemoglobin but also on the pH (acidity) of the blood, she said, and that can be altered by drugs and other chemicals.

Another thing that researchers may be seeing is “disseminated intravascular coagulation,” a condition that results from clotting in the lining of the capillaries. DIC can reduce or block blood flow where it is most needed and eventually cause organ damage. That’s an area for more research, Jen said, noting that these investigations are moving forward in collaboration with researchers at NMFS and the U.S. Fish and Wildlife Service.

Meanwhile, Jen is working with chemists at the University of Washington’s Center for Urban Waters in Tacoma to figure out which substances — out of hundreds of chemicals found in stormwater — could be causing these deadly effects on fish.

If isolating the dangerous compounds proves too difficult, researchers might be able to start with the original toxic sources, perhaps exposing fish to chemicals found in tires, oil, antifreeze and so on, Jen said. For those effects, it might be good to begin the investigation with the well-studied zebrafish embryos, which are transparent and can be observed closely throughout their embryonic development.

Needless to say, this is a field of intense interest. If researchers can discover what is killing coho, they might begin to understand why the recovery of chinook salmon in Puget Sound has been so slow. Chinook, which could be added to Jen’s studies, are listed as a threatened species under the Endangered Species Act and are the preferred prey of Puget Sound’s killer whales, which are listed as endangered.

Two recent articles discussed the relative hardiness of the chum compared to coho salmon:

Struggle for clean water criteria coming to a close

The long-running controversy over Washington state’s water quality standards for toxic chemicals is nearly over. We will soon know just how pure the water must be to get a clean bill of health.

chinook

We still don’t know whether the Environmental Protection Agency will approve the new state standards adopted this week or impose more stringent standards that EPA developed for several key pollutants. The EPA has already taken public comments on its proposed standards.

“We believe our new rule is strong, yet reasonable,” said Maia Bellon, director of the Washington Department of Ecology, in a news release. “It sets standards that are protective and achievable. With this rule now complete, we will continue to press forward to reduce and eliminate toxics from every-day sources.”

For more than two years, much of the controversy focused on the fish-consumption rate — an assumption about how much fish that people eat. The FCR is a major factor in the equation used to set the concentration of chemicals allowed in water before the waterway is declared impaired. (See early discussions in Water Ways, Nov. 11, 2010.)

Initially, after plenty of debate, the state proposed increasing the FCR from 6.5 grams per day to 175 grams per day — a 27-fold increase. The initial proposal counter-balanced the effect somewhat by increasing the cancer-risk rate from one in a million to one in 100,000 — a 10-fold shift. Eventually, the state agreed to retain the one-in-a-million rate.

As I described in Water Ways last October, some key differences remain between the state and EPA proposals. Factors used by the EPA result in more stringent standards. The state also proposes a different approach for PCBs, mercury and arsenic, which are not easily controlled by regulating industrial facilities and sewage-treatment plants — the primary point sources of pollution.

PCB standards proposed by the EPA make representatives of industry and sewage-treatment systems very nervous. Water-quality standards are the starting points for placing legal limits on discharges, and EPA’s standard of 7.6 picograms per liter cannot be attained in many cases without much higher levels of treatment, experts say.

“Available data indicate that most state waters would not meet the EPA proposed criteria and that most (federally permitted) wastewater treatment plants will have to apply membrane filtration treatment and additional treatment technologies to address PCBs,” according to a letter from five industrial organizations and a dozen major businesses (PDF 3 mb).

Entities in Eastern Washington are in the midst of planning efforts to control pollution in the Spokane River, and major sewer upgrades are under consideration, the letter says.

“If Ecology were to follow the same approach on Puget Sound that it has on the Spokane River, this would amount to a range of compliance costs from nearly $6 billion to over $11 billion for just the major permits identified by EPA,” the letter continues. “A more stringent PCB criterion is also likely to impact how stormwater is managed, as PCB concentrations have been detected in stormwater throughout the state.”

For pulp and paper mills using recycled paper, the primary source of PCBs is the ink containing the toxic compounds at EPA-allowed concentrations, the letter says. Other major sources are neighborhoods, where PCBs are used in construction materials, and fish hatcheries, where PCBs come from fishmeal.

sailing

The letter points out similar problems for EPA’s proposed mercury standard, calling the level “overly conservative and unattainable in Washington (and the rest of the United States), as the levels of mercury in fish are consistently higher than the proposed criterion.”

When water-quality criteria cannot be attained for certain chemicals using existing water-treatment technology, facilities may be granted a variance or placed under a compliance schedule. Both environmentalists and facility owners have expressed concern over uncertainties about how the agencies might use these approaches.

Despite the uncertainties, environmentalists and Indian tribes in Washington state generally support the more stringent standards proposed by the EPA.

“Tribes concur that water quality discharge standards are only a part of the toxic chemical problem in the state of Washington and that more efforts toward source control and toxic cleanup are needed,” writes Lorraine Loomis of the Northwest Indian Fisheries Commission. “However, the standards are an essential anchor for determining where and how to deploy toxic reduction efforts and monitor enforcement.”

When I said this controversy is nearly over, I was referring to a time schedule imposed this week by U.S. District Judge Barbara Rothstein, who ruled that the EPA missed its own deadlines for updating water quality criteria.

Rothstein, responding to claims from five environmental groups, imposed a new deadline based on EPA’s own suggested dates. Because the state has finalized its rule, the EPA now has until Nov. 15 to either approve the state’s criteria or sign a notice imposing its own standards. Checkout the judge’s ruling (PDF 494 kb).

The new criteria won’t have any practical effect until applied to federal discharge permits for specific facilities or in developing cleanup plans for specific bodies of water — although state inspectors could use the new state criteria for enforcing state laws if they discover illegal discharges.

If you want to dig a little deeper, view the full list of comments about Ecology’s proposal, many of which refer to the alternate EPA proposal as well. Ecology posts its information on its “Water Quality Rulemaking” page. EPA posts its information on the “Washington Water Quality Standards” page.

Culverts: Lawmakers face dilemma to fund improved fish passage

I’m certainly no highway engineer, but I’ve been thinking about the difference between building roads in Kansas, where I was born, and building roads in the Puget Sound region.

Kansas has its streams and wetlands to be sure, but nothing like the density of natural features that we find in the Puget Sound watershed, where land elevations change constantly and roadways must cross streams and wetlands at every turn.

For many years, road construction in the Puget Sound region involved filling wetlands and burying pipes just big enough to pass the water. It was assumed that salmon would make it through. But based on our current knowledge of salmon migration, we realize that these shortcuts took a major toll on the populations of salmon and other fish.

This week, the U.S. Ninth Circuit Court of Appeals upheld a lower court ruling requiring state agencies to correct decades of road-building mistakes that impaired salmon passage on state highways and on state forest roads. Check out Monday’s story in the Kitsap Sun.

Priority watersheds chosen by the Fish Barrier Removal Board. Puget Sound: Pilchuck Creek, Pysht River, Goldsborough Creek; Coast: Newaukum; Lower Columbia: Lower Cowlitz; Yakima River: Wilson/Cherry; Snake River: Grande Ronde Tribs, Snake River Tribs; Upper Columbia: Okanogan.

The lawsuit, filed by 21 Indian tribes, was based on the idea that undersized and poorly functioning culverts severely affected the total salmon runs in violation of treaties signed in the 1850s, which promised Native Americans the right to fish forever in traditional locations.

The lawsuit did not address culverts owned by the federal government, local governments or private property owners, but the same principles apply. Steps are now being taken to improve salmon passage based on standards developed by the Washington Department of Fish and Wildlife.

Meanwhile, a state advisory committee, known as the Fish Barrier Removal Board, has been working to establish priorities with top-ranked projects providing the greatest improvement in salmon habitat.

Kitsap County Engineer Jon Brand, who serves on the board, described a two-pronged approach to set the priorities. One is to focus on priority watersheds, with the idea of making major improvements in a variety of streams in a given area. (See map above and board materials (PDF 50.4 mb), Oct. 20, 2015.) The second approach is to coordinate planning for top-priority streams, with the idea of working on entire stream systems at once. Obviously, it does not make sense to replace a culvert upstream if a downstream culvert continues to block salmon passage. Check out the list of top-30 ranked projects (PDF 57 kb).

The Fish Barrier Removal Board is putting together a funding package to be submitted to the Legislature. As Jon pointed out, some of the most effective projects for salmon passage are not in the Puget Sound region nor subject to the federal court ruling. The list also goes beyond state roadways and includes a mix of ownerships based on the watershed and stream priorities mentioned above.

State lawmakers face some difficult funding decisions. With the court order hanging over their heads, along with a 2030 deadline, they may choose to do only culvert-removal projects in the Puget Sound region, even though projects in other areas could get a greater bang for the buck. And will there be money left over to support local governments trying to improve salmon passage in their areas?

I asked Jon about the expediency of early road-builders who must have given little consideration to salmon when they filled wetlands, carved out drainage ditches and installed pipes to carry the flow of water. It was not always that way, Jon told me.

That method of road-building arrived with the invention of large earth-moving equipment, he said. In the 1800s and early 1900s, filling a stream and inserting a culvert was more difficult than building a bridge of logs, given the vast quantities of timber on the Kitsap Peninsula.

Those early log bridges no doubt caused fewer problems for salmon, but they did not last. Eventually, nearly every bridge was replaced, often by dumping fill across the stream and allowing a small culvert to carry the water.

As for my misguided notion that Kansas can ignore stream crossings because the state has no serious environmental problems, I found this language in “Kansas Fish Passage Guide” (PDF 2.3 mb), a document written for road-builders:

“In Kansas, fish passage issues caused by culverts were not recognized by road officials until about 2010, when … research indicated that culverts and low-water crossings were a significant cause of habitat fragmentation in the Kansas Flint Hills.

“Many of the threatened and endangered fish in Kansas are a type of minnow or minnow-size fish. Small fish typically are not strong swimmers, so waterfalls, water velocity and turbulence can be a barrier to passage upstream. Culverts are dark and have an atypical channel bottom that may also discourage fish passage. Lack of water depth through the culvert can restrict passage during low-flow seasons…

“Stream barriers reduce habitat range and can adversely affect fish populations upstream and downstream of the stream crossing. A severe event like a drought or oil spill in a stream segment can wipe out a species, and the species cannot repopulate the stream because of the barrier.”

Kansas has begun to prohibit blocking culverts and to address existing fish-passage issues. As the above-referenced publication states, “On the Great Plains, it’s usually easy to design and construct a stream crossing for a two-lane road to provide fish passage.”

If only that were the case in Western Washington.

Upper Skokomish designated as ‘properly functioning’ watershed

More than 20 years of removing and reconstructing old logging roads in the Skokomish River watershed has finally paid off with measurable improvement to water quality and habitat, according to experts with Olympic National Forest where millions of dollars have been spent on restoration.

In a U.S. Forest Service project nicknamed “the Big Dig,” contract crews removed nearly 100 vertical feet of road in the South Fork of the Skokomish watershed to remove an eight-foot culvert. The work allowed a mountain stream to flow freely into the Skokomish River. Photo: Kitsap Sun, Steve Zugschwerdt.

The U.S. Forest Service this week declared that the upper South Fork of the Skokomish is now a “properly functioning” watershed, and the major road-restoration projects are complete.

After writing for years about horrendous problems with sediment washing out of the upper watershed, this news comes as a nice surprise. I’ve been hearing experts talk about water-quality improvements, but this new declaration is a major milestone in the restoration of the entire Skokomish River ecosystem.

“This is a proud and historic occasion for the Forest Service and our many partners who have worked very hard for over two decades to restore this once badly degraded watershed,” Reta Laford, supervisor for Olympic National Forest, said in a news release.

In 2010, the Forest Service classified the South Fork Skokomish as an “at-risk” watershed during a nationwide effort called the Watershed Condition Framework. Several other watersheds in Olympic National Forest also received this designation. See the map at the bottom of this page or download (PDF 5.3 mb) from the Forest Service website.

In 2012, Olympic National Forest designated the upper and middle South Fork Skokomish sub-watersheds as “priority watersheds.“ Forest Service officials pushed forward with action plans containing a list of restoration projects designed to put the watersheds on a path to ecological health.

For your review:

Completion of the key restoration projects in the upper South Fork allowed for the new designation as a “properly functioning” watershed. This marks the first time that any watershed in Olympic National Forest has been upgraded due to completion of all essential restoration projects. Watershed conditions and aquatic habitat will continue to improve as natural processes roll on.

Restoration in the South Fork actually began in the early 1990s, when the Forest Service acknowledged that the region was criss-crossed by a damaging network of logging roads. At nearly four miles of road for every four one square mile of forest, it was one of the densest tangles of roads in any national forest.

In 1994, the Forest Service designated the South Fork Skokomish as a “key watershed” in the Northwest Forest Plan, which called for major cutbacks in logging and received support from President Bill Clinton. Between the early 1990s and 2005, Olympic National Forest completed $10.6 million in restoration work, including $7.9 million for road decommissioning, road stabilization and drainage improvements.

In 2005, the Skokomish Watershed Action Team (SWAT) was formed among a coalition of more than 20 government agencies, environmental organizations and business groups with diverse interests. The SWAT developed a unified front for promoting restoration projects and seeking funds. Members agreed that the focus on roads should begin with the upstream segments, later moving downstream, while other work was coordinated on the estuary near Hood Canal. Much of the lower area was owned or acquired by the Skokomish Tribe, a critical partner in the SWAT.

Between 2006 and 2015, the Forest Service continued with $13.2 million in restoration projects in the South Fork, including $10.9 million on road problems. In all, 91 miles of roads were decommissioned, closed or converted to trails, and 85 miles of roads were stabilized or improved with new culverts and drainage features.

In 2008, I wrote about the problems and response of the SWAT in a Kitsap Sun story: “Taking (Out) the High Roads to Save the Skokomish.”

Much of the road restoration work was funded by Congress through the Forest Service’s Legacy Roads and Trails Program. Former U.S. Rep. Norm Dicks was instrumental in creating that program, and congressional support has continued under the leadership of Norm’s successor, U.S. Rep. Derek Kilmer, and U.S. Sens. Patty Murray and Maria Cantwell.

Key funding for restoration also has come from the Forest Stewardship program, which uses receipts from commercial timber thinning on forest lands. Other financial support — especially in the lower watershed — has come from the state’s Salmon Recovery Funding Board and the U.S. Environmental Protection Agency.

In 2009, I wrote a story for “Wilderness” magazine about how these programs were bringing “green jobs” to the region.

Meanwhile, the U.S. Army Corps of Engineers completed an in-depth study of the river’s ecosystem last year and is now seeking funding from Congress for a series of projects in the watershed. Check out Water Ways, April 28, 2016.

To celebrate this milestone for Olympic National Forest, the SWAT will recognize the work at its general meeting Friday at the Skokomish Grange Hall, 2202 W. Skokomish Valley Road. The meeting begins at 9 a.m., and the public is invited.
