Purchase of Big Beef Creek property preserves habitat, research projects

Nearly 300 acres along Big Beef Creek near Seabeck will be protected from development and could maintain its research facilities, thanks to a $3.5-million land purchase arranged by the Hood Canal Salmon Enhancement Group.

The property, owned by the University of Washington, contains the Big Beef Creek Research Station, known for its studies of salmon and steelhead. The UW purchased the land, including most of the estuary, in 1965. Various research projects have continued there, despite the university’s decision to sell the property.

Mendy Harlow, executive director of the Hood Canal Salmon Enhancement Group, said she has been working with multiple funding agencies and nonprofit groups for two years to finalize the acquisition.

“Some funding sources only want to pay for estuary habitat,” she said. “Some don’t want to have any buildings on the site. Others have other priorities. But everybody had a great can-do attitude, and they all wanted to make this work.”

The future of the research station will depend on a feasibility study, which will assess who wants to use the facilities and how proposed operations can be accommodated along with plans to restore the ecosystem.

Land purchased from the University of Washington involves 13 parcels along Big Beef Creek, with Hood Canal at top.

“We realize that we can’t have full restoration with buildings located in the flood plain,” Harlow said, “but people are already calling me to see if they can work with us. I feel the possibilities are very broad.”

The research station has multiple buildings, including some being used as office space. One building houses incubators designed to hatch salmon eggs. Nine large tanks are available for rearing fish of all sizes.

The facility also has an artificial spawning channel, used during the 1990s to observe salmon behavior. Freshwater ponds, once built for rearing chinook salmon, will undergo scrutiny for potential uses versus restoration back to a more natural condition, Harlow said.

The property is closed to the public, but planning efforts will consider public uses, including trails and recreational activities such as bird watching and fishing.

Big Beef Creek is also under consideration for an effort to restore a natural run of summer chum, a population that disappeared from Big Beef Creek in 1984. A decade later, the entire population of Hood Canal summer chum was listed as threatened under the Endangered Species Act.

In the late 1990s and into the 2000s, biologists attempted to restore the salmon run by using summer chum from the Quilcene River on the other side of Hood Canal. That experiment failed, despite successful restoration in other Hood Canal streams. Experts are still assessing the cause of the Big Beef Creek failure and may try again, perhaps with a different stock under different conditions — including better habitat, thanks to stream restoration in 2016 and 2017.

Although the Hood Canal Salmon Enhancement Group now owns the Big Beef property, a fish trap operated by the Washington Department of Fish and Wildlife will continue to be used by the agency to count salmon coming and going from Big Beef Creek. Those counts are used to predict salmon runs and set harvest levels in Hood Canal.

The property acquisition involved grants totaling $1.9 million from grant programs administered by the Recreation and Conservation Funding Board, the Salmon Recovery Funding Board and the Office of Estuary and Salmon Restoration. Another $980,000 came from the U.S. Fish and Wildlife Service.

Fortera, a nonprofit organization, provided $152,000 for the initial purchase and used a loan guarantee from the Russell Family Foundation to buy two remaining parcels. Those properties will be transferred to HCSEG after about $400,000 is raised for the final purchase.

With the acquisition of the research station property, 90 percent of the land along Big Beef Creek below the Lake Symington dam is in public ownership or conservation status, Harlow said. The goal is to acquire more property to continue streamside restoration from the dam to Hood Canal while continuing to improve salmon habitat above the dam.

Without the purchase of the research station property, an important part of Hood Canal could have been lost to development, Harlow said.

“We have been involved with Big Beef Creek for a couple of decades now,” she said. “It is really wonderful to see things working out this way.”

Amusing Monday: Pacific Research Expedition shown live on video

Deep-sea corals and sponges are the focus of an intense research program now exploring the seabed along the West Coast. Live video from the bottom of the ocean can be viewed via the research ship Reuben Lasker, owned by the National Oceanic and Atmospheric Administration.

I’ve posted the two primary video feeds on this page, or you can link to the video pages associated with the 29-day expedition, which began a week ago and will continue until Nov. 7. Previous video recordings are often shown when live video is not available.

The research cruise is exploring the seabed off the Washington, Oregon and California coasts, as shown in the map below. Researchers are using Yogi, a tethered remotely operated vehicle (ROV), as well as SeaBED, an untethered autonomous underwater vehicle (AUV), to collect samples of corals and sponges and observe changes in previously surveyed sites.

“Recent advances in deep-ocean exploration have revealed spectacular coral gardens in the dark ocean depths, far from the sunny, shallow reefs most of us associate with corals,” states a description of the mission. “Similar explorations have revealed new and familiar species thriving where we once expected little activity.”

Proceeding from north to south, the sites to be surveyed (green dots) are Willapa Canyon head, North Daisy Bank, Sponge bycatch Oregon shell, Brush Patch, Humboldt and Mad River, and Mendocino Ridge before a layover Oct. 19-22, followed by Cordell Bank/Farallones, Cabrillo Canyon, West of Carmel Canyon, Monterey Bay, wind site, Santa Lucia Bank, Channel Islands and Catalina Basin.

One goal is to characterize habitats at 12 specific sites along the West Coast. That information could help the Pacific Fishery Management Council modify fishing regulations while protecting essential fish habitat. Survey data may also suggest feasible locations — and locations to avoid — when developing offshore wind power and other energy projects.

The expedition is a collaboration of NOAA, the Global Foundation for Ocean Exploration, the U.S. Geological Survey (USGS), and the Bureau of Ocean Energy Management (BOEM). The expedition consists of two legs: from the Washington Coast to San Francisco, where a public event will be held at the Exploratorium Museum, followed by the second leg from San Francisco to San Diego.

“With every survey I’ve been a part of there’s a frantic flurry of last-minute logistics getting the expedition together and loading the ship,” Elizabeth Clarke, co-leader of the voyage, said in a news release. “Once we start the expedition, however, things settle down and we start each day excited, wondering what new discoveries we will find.”

As of today (Monday, Oct. 14), poor weather conditions had delayed activities on the bottom since last night. “We are looking to get back in the water tomorrow (10/14) evening, weather permitting,” states last night’s Twitter feed, @Discover_GFOE, which is the best way of keeping track of the voyage.

Spring Chinook take on high flows because of ‘early-migration gene’

It’s a bit mind-boggling to think that a single, tiny fragment of genetic material determines whether a Chinook salmon chooses to return to its home stream in the spring or the fall.

I’ve been following the scientific discoveries about spring chinook since 2017, when Mike Miller’s lab at the University of California, Davis, published research findings showing the location of this “early-migration gene” on chromosome 28.

In a story published this week in the Encyclopedia of Puget Sound, I wrote about some of the latest discoveries surrounding spring Chinook. I also thought it worthwhile to describe the importance of these fish to the ecosystem and to the native people of the Puget Sound region.

Up until the past two years, I never gave much thought to spring Chinook, nor apparently have most people, including many biologists. These are the salmon that often struggle to reach the upper reaches of the rivers when the streams are swollen with spring snowmelt. Much of these upper spawning grounds have been destroyed by human activity, and more than half the spring chinook runs in Puget Sound have gone extinct.

The more I learned about spring Chinook the more fascinated I became. The southern resident killer whales used to arrive in Puget Sound in April or May to feast on spring Chinook from Canada’s Fraser River, but those salmon runs have declined along with many fall runs of chinook. The result is a major change in behavior and migration patterns by the whales.

Spring Chinook were at one time an important food for bears coming out of hibernation, for eagles who had scavenged for food through the winter, and for native people who looked forward to fresh fish after a season of dried foods.

As I researched this story, I learned about the history of spring Chinook in the Skokomish River of southern Hood Canal and how a once-plentiful fish became extinct. I was pleased to describe the success of current efforts to create a new run of spring Chinook with the help of a hatchery in the North Fork of the Skokomish, where adult spawners are showing up nearly a century after the fish disappeared.

Genetics is a fascinating field, and advances are coming rapidly in the studies of many species, including humans. The idea that a single gene can completely change the migration timing of a Chinook by four months raises many scientific and legal questions — including whether spring Chinook should get their own protection under the Endangered Species Act. As things stand now, Chinook salmon in Puget Sound — both spring and fall together — are listed as threatened under the ESA. But that could change as things shake out with the ESA in Oregon and California.

Ongoing genetic studies — including those involving various salmon species — are causing biologists and legal experts to re-examine the criteria for listing populations as threatened or endangered, as they teeter on the edge of extinction. No matter what the extinction risk is judged to be, spring Chinook are now recognized as something very special.

Orcas return to Puget Sound; critical habitat proposed for coast

It appears that the southern resident killer whales have begun to travel into Central and South Puget Sound for their annual fall feast of chum salmon, according to past experience and dozens of reports from shoreside observers.

Meanwhile, the federal government has proposed extending their designated “critical habitat” beyond Puget Sound to the outer coast of Washington, Oregon and Northern California.

The critically endangered orcas have mostly been away from Puget Sound this summer, as their frequency of visits has declined in recent years. During the spring and summer, their primary prey is chinook salmon. But they tend to follow schools of chum salmon in the fall, and it is possible that recent rains got the chum moving a little faster toward their many home streams.

It appears the whales came in and traveled as far south as Seattle and the southern end of Bainbridge Island Thursday and were headed back north today. They could make another loop of Puget Sound, or they could head out to sea and return later. Check out Orca Network’s Facebook page for ongoing sighting reports. Kitsap Sun reporter Jessie Darland describes their arrival.

The expanded critical habitat, proposed by the National Marine Fisheries Service, totals 15,627 square miles along the continental shelf of the Pacific Ocean. When finalized, federal agencies will be required to protect the orcas’ habitat as well as the orcas themselves.

By 2014, scientists at NMFS had been gathering data for several years in support of such an expansion when the Center for Biological Diversity filed a petition (Water Ways, Jan. 19, 2014) urging the government to finally take action. The agency agreed to move forward but continued to delay until after the group filed a lawsuit, which led to this week’s proposal.

Notably, the proposal does not include the Center for Biological Diversity’s idea to include safe sound levels as an important quality of the killer whale habitat. The group wanted to make sure the whales could hear well enough to use their echolocation to hunt fish, and they wanted to keep the animals from experiencing sounds that could cause partial or total deafness.

The agency looked at the issue but concluded that it does not have a way to establish a threshold sound level that could be considered harmful, although non-quantitative noise levels have been used to protect Cook Inlet beluga whales and Main Hawaiian Island false killer whales. For now, NFMS kept the essential habitat features for killer whale habitat to three things:

  1. Water quality to support growth and development,
  2. Prey species of sufficient quantity, quality and availability to support individual growth, reproduction, and development — as well as overall population growth, and
  3. Passage conditions to allow for migration, resting, and foraging.

Based on experience, NMFS said its biologists could already address adverse effects of man-made noise under the habitat categories of prey and passage. If noise were to affect the whales’ ability to hunt, for example, the problem could come under “prey species.” If noise were to discourage them from traveling to or resting in a specific area, it could come under “passage conditions.”

The Navy’s Quinault Range Site, where sonar and explosives are used in testing and training operations off the Washington coast, was excluded from the critical habitat designation following an evaluation by NMFS. Also excluded was a 10-kilometer (6.2-mile) buffer around the range.

“The Navy argued that there would be national security impacts if NMFS required additional mitigation that resulted in the Navy having to halt, reduce in scope, or geographically/seasonally constrain testing activities to prevent adverse effects or adverse modification of critical habitat,” NMFS noted in its findings.

The Navy has developed operational procedures to limit the harm to killer whales and other marine life, as required by the Endangered Species Act, Marine Mammal Protection Act and court rulings. While NMFS agreed to exclude the Quinault Range Site, it did not extend the exclusion to other Navy operational areas on the Washington coast.

Julie Teel Simmonds, an attorney with the Center for Biological Diversity, told me that officials in her group will carefully scrutinize that proposed exclusion area.

“Their decision to exclude is discretionary,” she wrote in an email, “but we will be evaluating their analysis during the public comment period, particularly given the plight of the orca and the concerns we have with some of the Navy’s activities, particularly certain harmful sonars.”

Brad Hanson and other marine mammal biologists at the NMFS’ Northwest Fisheries Science Center spent years evaluating where the orcas traveled in the ocean and what they were eating. They tracked the whales by attaching satellite transmitters, recorded their sounds on hydrophones along the coast, and collected sighting reports from a variety of people.

They learned that when the three pods of southern resident orcas were on the coast they spent more than half their time off Washington state, often between Grays Harbor and the Columbia River. Their travels often corresponded with an abundance of salmon.

While K and L pods have been observed in coastal waters every month of the year, J pod ventured to the coast infrequently and only in northern waters. All three pods spent nearly all their time within about 20 miles of shore and in waters less than 650 feet deep.

Through the years, I have written extensively about these studies. Here are a few blog posts:

Although the southern residents frequent the waters of British Columbia, the proposed critical habitat was limited to U.S. waters, because of the extent of U.S. jurisdiction. A single confirmed sighting of southern residents in Southeast Alaska in 2007 was not considered adequate to add any area to the north.

As a result of the expanded critical habitat, a number of activities will come under federal review with respect to protecting habitat as well as animals. They include salmon fishing, salmon hatcheries, offshore aquaculture, alternative energy development, oil exploration and drilling, military activities, and onshore activities that could create pollution.

NMFS was unable to identify any specific construction projects or maritime activities that would be affected significantly beyond the existing reviews required by the Endangered Species Act. The total additional cost of reviewing permits and analyzing potential impacts of projects was estimated at $68,000 a year.

Comments on the proposal may be submitted until Dec. 18. For information, check out the various documents on NMFS’ Southern Residents Critical Habitat website.

Native Olympia oysters expected to gain a new foothold in Sinclair Inlet

A massive amount of oyster shell — some 1,500 cubic yards — will be dumped into Sinclair Inlet near Gorst next week to lay the groundwork for a healthy population of native Olympia oysters.

Limited numbers of Olympia oysters have been growing in Sinclair Inlet, hanging on since long ago, said Betsy Peabody, executive director of Puget Sound Restoration Fund, which is managing the operation. Existing oysters probably just need the right substrate for their larvae to attach, grow and ultimately expand the native oyster population.

The $300,000 project — which will deposit the equivalent of 150 dump-truck loads of Pacific oyster shells — will be the largest one-time application of shells anywhere in Puget Sound, Betsy told me. Her organization has undertaken similar projects in other areas, including Liberty Bay near Poulsbo, Dogfish Bay near Keyport, Dyes Inlet near Bremerton and Port Gamble Bay on Hood Canal.

The yellow area marks the location in Sinclair Inlet where oyster shell will be placed.

The shells, which came from commercial oyster farms, will be washed off a 200-foot barge using a jet of water beginning Tuesday and taking up to four days, according to the current schedule. The shell will cover some 15 acres of tidelands toward the middle of the inlet where Highway 166 branches off Highway 16.

This washing process typically creates a patchwork of shell covering about 80 percent of the bottom while 20 percent remains bare, according to plans for the project. The thickness of shell on the bottom will vary, reaching up to 3 inches in some places. No eelgrass or other sensitive vegetation was found during surveys of the tidelands to be covered. The property is owned by Kitsap County.

In the early 1900s, Sinclair Inlet was used as an 122-acre oyster reserve for protecting seed stock, which could be purchased by commercial oyster growers. Oyster reserves throughout Puget Sound were largely forgotten after Pacific oysters — a different species imported from Japan — began to dominate the oyster market.

Olympias went extinct in some areas, killed by pollution, shoreline development or other factors. In a few areas, habitat was largely undisturbed and the original oyster species persevered. But many embayments, including Sinclair Inlet, were able to support only a fraction of their historic populations.

“Olys evolved in this area and managed to maintain a foothold in the most surprising areas, despite what we’ve thrown at them over time,” Betsy said. “They are tough little critters. You can even find them in places where everything else is plastic. Building back their densities seems like a good thing to do.”

Oysters have a number of good qualities besides being a favorite food of many people. They can filter out plankton that can trigger low-oxygen conditions. Plankton also reduce sunlight needed for critical vegetation, such as eelgrass.

The 19 areas in Puget Sound declared a high priority for Olympia oyster restoration.
Map: Washington Department of Fish and Wildlife

Washington Department of Fish and Wildlife has designated Sinclair Inlet as one of 19 priority restoration sites for Olympia oysters in the Puget Sound region. See “Plan for Rebuilding Olympia Oyster (Ostrea lurida) Populations in Puget Sound…”(PDF 559 kb)

In natural oyster beds, young oysters are able to set and grow on the shells of their ancestors, often forming oyster beds or reefs that help perpetuate the substrate for future generations. Sedimentation and damage to the shoreline can interrupt the process and eliminate the substrate needed for the oyster to survive. Putting down a lot of shell to create new substrate has proven to be the best way to boost the population in most areas of Puget Sound.

If the Olympia oysters do well in Sinclair Inlet, eventually more shell could be brought in to expand the growing area, Betsy said. If, however, natural production of oyster larvae is not enough, PSRF could develop a broodstock program by utilizing its shellfish hatchery near Manchester, as has been done for other areas. If that were to happen, adequate numbers of Olympia oysters from Sinclair Inlet would be used to produce the oyster seed, thus maintaining the genetic diversity of the inlet.

In 2010, Puget Sound Restoration Fund established a goal of restoring 100 acres of Olympia oyster habitat with shell placed in bays where the native oysters are expected to do well. The Sinclair Inlet project will bring the total to 85 acres, with other areas in the planning stage to help the group meet its goal by the end of next year.

About half of the $300,000 being used for the Sinclair Inlet project came from the federal Natural Resources Conservation Service, with other funding from the Washington Department of Ecology, Kitsap County and PSRF. The Suquamish Tribe also participated in the project.

New site to be added for fall salmon-viewing on Kitsap’s Chico Creek

The most popular spot on the Kitsap Peninsula to watch salmon swimming upstream to spawn will be off-limits to the public this fall — but Kitsap County officials have a backup plan.

Chico Salmon Park, located off Chico Way next to Kitsap Golf and Country Club, will remain closed until the fall of 2020 while a new bridge is built across Chico Creek on Golf Club Hill Road.

The park, which includes trails to Chico Creek, is the best place I know for people to observe this natural phenomenon during the fall migration of chum salmon, which are still abundant in the Chico Creek and its various tributaries.

The plan this year is to allow people to reach Chico Creek at the 30-acre Erlands Point Preserve, a county-owned property less than half a mile away, off Erlands Point Road. Volunteer stewards will clear an overgrown trail and build a new gravel viewing pad near the stream, according to Jackson Lee, volunteer coordinator with Kitsap County Parks.

Amusing Monday: ‘Plein air’ art captures beauty of Columbia Gorge

More than 40 artists traveled to the Columbia River Gorge in late July to participate in what was essentially a four-day paint-off — a competition to see who could best capture the heart and soul connected to this rare and magnificent landscape.

While I often feature artwork that receives recognition in children’s art contests, I was impressed by the professional paintings in the 14th annual Pacific Northwest Plein Air competition that was completed a little over a week ago, and I wanted to share them with you. The competition, sponsored by Maryhill Museum of Art, features artists from throughout the Northwest and a few from more distant locales.

Old bulkhead to be removed on Ross Point, a major surf smelt beach

Ross Point, the most popular fishing spot for surf smelt in Kitsap County, will become a little more friendly to the little fish following the removal of a concrete bulkhead along the shore of Sinclair Inlet.

The bulkhead removal, scheduled to begin Aug. 12, will create more spawning area for surf smelt, an important food source for salmon and other fish. Smelt also are favored eating by some people, who typically catch them with dip nets.

In addition to increasing smelt habitat, the project will enhance the migration of young salmon along the southern shore of Sinclair Inlet. Like most bulkheads built in the tidal zone, this 84-foot-long structure forces juvenile salmon to swim into deeper water out from shore, making them more vulnerable to predators.

Amusing Monday: Sand sculptors worldwide continue to amaze

While I have never been to Revere Beach, I look forward each year to photos of the amazing sand sculptures from a competition that brings people from throughout the world to this location just north of Boston.

The winning entry in the Revere Beach sand sculpting contest was “Nest” by Mélineige Beauregard of Montreal, Canada. // Photo: Revere Beach Partnership

Adding to the enjoyment of the Revere Beach International Sand-Sculpting Festival are longtime sand-sculptors Dan Doubleday and Meredith Corson-Doubleday, who bring the event to life, especially for distant viewers, with their expert commentary on all the pieces. I also appreciated the slide show created by professional photographer Greg Cook on his Wonderland website.

The sand sculptures are evaluated using four categories: (1) degree of difficulty, (2) originality and creativity, (3) quality of sculpting, and (4) overall visual impact.

In the two videos on this page, Dan and Meredith conduct their fourth-day “walkthrough” together, as the sand sculptures take on their final forms. At the time that Dan and Meredith recorded their commentary, they did not know who the winners would be, so I would like to add some help with that:

Fisheries innovations credited with West Coast groundfish recovery

The dramatic recovery of many groundfish species along the West Coast is a testament to the innovation, cooperation and persistence by fisheries managers and fishermen alike under the landmark Magnuson-Stevens Act of 1976.

One of the latest innovations, formally approved last month by the National Marine Fisheries Service, is “electronic monitoring,” which allows the use of video and other equipment in place of the human observers needed to ensure the accuracy of harvest reports.

The faster-then-expected recovery of depleted populations — including canary rockfish, bocaccio, darkblotched rockfish, and Pacific Ocean perch — has led to dramatically increased harvest limits this year. NMFS estimates that increased fishing will add 900 jobs and $60 million in income this year alone. Recreational anglers are expected to go fishing an additional 219,000 times, mostly in California with some of those outings in Oregon and Washington, according to a news release.

Going from a federally declared disaster in 2000 to today’s recovery of most stocks was the result of a monumental change in fisheries management and fishing culture. One of the biggest changes was a shift to “catch shares,” in which each commercial fisherman receives a percentage of the allowable harvest each year, an issue I first wrote about a decade ago (Water Ways, Dec. 11, 2009).
