Hood Canal changes color again, thanks to plankton bloom

Hood Canal has changed colors again, shifting to shades of bimini green, as it did in 2016, when satellite photos showed the canal standing out starkly among all other waters in the Northwest.

The color change is caused by a bloom of a specific type of plankton called a coccolithophore, which shows up in nutrient-poor waters. The single-celled organism produces shells made of calcite, which reflect light to produce the unusual color.

Observers are now waiting for the clouds to depart, so we can get new satellite images of the green waters.

The plankton bloom started June 1 in Quilcene and Dabob bays, according to Teri King of Washington Sea Grant. It came about a week earlier than last year and has since spread through Hood Canal. Observers in the Seabeck area reported seeing the bloom the past few days. The bimini green color, which gets its name from an island in the Bahamas, is especially noticeable when the sun comes out.

Coccolithophores are known for dominating other phytoplankton when there is a shortage of nutrients, such as nitrogen, in the water. We usually get an influx of nutrients when it rains, so I’m not sure how long the bloom may last. I’m told, however, that the white calcite shells, called coccoliths, can stick around after the organism has died, although they eventually sink to the bottom.

The species of coccolithophore in Hood Canal is believed to be Emiliania huxleyi, shown in the microscopic photo on this page. They don’t produce any known toxins harmful to people or marine life, experts say, and they can be eaten by small fish and larger zooplankton.

Puget Sound freshens up with a little help from winter snowpack

In the latest “Eyes Over Puget Sound” report, one little note caught my attention: “Puget Sound is fresher than it’s ever been the past 17 years.”

At least temporarily, something has changed in the waters of Puget Sound over the past few months. It may not last, but it appears to be a good thing.

The monthly EOPS report, compiled by a team of state environmental experts, lays out recent water-quality data for the Department of Ecology. The report also includes personal observations, aerial photographs and scientific interpretations that keep readers abreast of recent conditions while putting things in historical context.

The “fresh” conditions called out in the report refers to the salinity of Puget Sound, which is driven largely by the freshwater streams flowing into the waterway. The reference to 17 years is a recognition that the overall salinity hasn’t been this low since the current program started 17 years ago.

Dissolved oxygen, essential to animals throughout the food web, was higher this fall than we’ve seen in some time. Hood Canal, which I’ve watched closely for years, didn’t come close to the conditions that have led to massive fish kills in the past. The only problem areas for low oxygen were in South Puget Sound.

Water temperatures in the Sound, which had been warmer than normal through 2015 and 2016, returned to more average conditions in 2017. Those temperatures were related, in part, to the warm ocean conditions off the coast, often referred to as “the blob.” In South Puget Sound, waters remained warm into October.

Why is the water fresher this fall than it has been in a long time? The reason can be attributed to the massive snowpack accumulated last winter, according to oceanographer Christopher Krembs, who leads the EOPS analysis. That snowpack provided freshwater this past spring, although rivers slowed significantly during the dry summer and continued into September.

“We had a really good snowpack with much more freshwater flowing in,” Christopher told me, adding that the Fraser River in southern British Columbia was well above average in July before the flows dropped off rapidly. The Fraser River feeds a lot of freshwater into northern Puget Sound.

Freshwater, which is less dense than seawater, creates a surface layer as it comes into Puget Sound and floats on top of the older, saltier water. The freshwater input fuels the circulation by generally pushing out toward the ocean, while the heavier saltwater generally moves farther into Puget Sound.

“The big gorilla is the upwelling system,” Christopher noted, referring to the rate at which deep, nutrient-rich and low-oxygen waters are churned up along the coast and distributed into the Puget Sound via the Strait of Juan de Fuca. Lately, that system has been turned down to low as a result of larger forces in the ocean.

In an advisory issued today (PDF 803 kb), NOAA’s Climate Prediction Center says a weak La Niña is likely to continue through the winter. For the northern states across the country, that usually means below-average temperatures and above-average precipitation. (It’s just the opposite for the southern states.)

With a favorable snowpack already accumulating in the mountains, experts can’t help but wonder if we might repeat this year’s conditions in Puget Sound over the next year.

Christopher told me that during aerial flights this fall, he has observed fewer jellyfish and blooms of Noctiluca (a plankton known to turn the waters orange) than during the past two years. Most people think this is a good thing, since these organisms prevail in poor conditions. Such species also have a reputation as a “dead end” in the food web, since they are eaten by very few animals.

Christopher said he noticed a lot of “bait balls,” which are large schools of small fish that can feed salmon, birds and a variety of creatures. “I assume most of them are anchovies,” he said of the schooling fish.

I would trade a jellyfish to get an anchovy on any day of the year.

A trick question: Can you locate Anderson Creek?

Let’s talk about Anderson Creek in Kitsap County. Where exactly is that stream?

If you were to say that Anderson Creek is a stream that spills into Hood Canal near Holly, you would be right.

If you are thinking of another Hood Canal stream — the one that you cross north of Seabeck while traveling on Anderson Hill Road — that would be right, too.

And nobody could complain if you believe that Anderson Creek is the name of the stream that flows into Sinclair Inlet near Gorst.

Officially, they are all Anderson Creek, according to the Geographic Names Information System, the official database of true names. GNIS is maintained by the U.S. Geological Survey.

I discovered the existence of three Anderson Creeks in Kitsap County as I sat down to blog about a new bridge project being planned on Seabeck-Holly Road north of Holly — over a stream I have always called Big Anderson Creek.

These are the opening lines of the county’s announcement about the bridge work: “Kitsap County Public Works begins construction of a new bridge on Seabeck-Holly Road at the Anderson Creek crossing beginning July 18, 2017.”

I immediately thought that someone in Public Works must have accidentally shortened the name from Big Anderson Creek to Anderson Creek, but I guess I was wrong. I mean, doesn’t everyone call it Big Anderson Creek?

I conducted an online search for “Big Anderson Creek” in Kitsap. Many reliable sources have been calling it Big Anderson Creek in dozens of documents for at least several decades. To name a few of the agencies using the “wrong” name:

  • Hood Canal Coordinating Council in its “Summer Chum Salmon Recovery Plan,”
  • Kitsap Public Health District in its annual “Water Quality Monitoring Report,”
  • Kitsap Public Utility District in its water supply assessment,
  • Kitsap County Department of Emergency Management in its multi-hazard-mitigation plan,
  • Washington Department of Ecology in its inventory of stream-monitoring programs,
  • Point No Point Treaty Council in its nearshore habitat assessment for Hood Canal,
  • Hood Canal Salmon Enhancement Group in its annual report of restoration projects,
  • The Trust for Public Land in its “Assessment for Freshwater Habitat for Puget Sound Salmon,”
  • And, last but not least, Big Anderson Creek is the name used by Kitsap County Public Works in its stream-monitoring program.

Little Anderson Creek, the one farther north, is in the same boat as Big Anderson Creek. A lot of people use the descriptive “Big” and “Little” when talking about the two streams, but officially they are wrong, according to my assessment.

Ed Smith, Public Works project manager for the bridge construction, told me that he will keep calling it “Anderson Creek.” That’s the official name on the maps that he uses. It is also the name listed on the “hydraulic project approval” issued by the Washington Department of Fish and Wildlife to authorize construction.

Through the years, I’ve written quite a lot about confusing and conflicting names, but I never had a clue about the discrepancy involving Big and Little Anderson creeks. If someone reading this has the time and dedication to officially change the names of these two streams, I don’t think anyone would object. The process begins with an application to the Washington State Committee on Geographic Names. The committee’s coordinator, Caleb Maki, can help people work their way through the process. Please let me know if you tackle this project.

Meanwhile, I will continue using the popular nomenclature of Big and Little Anderson creeks.

As for the new bridge over Big Anderson Creek, a 50-foot concrete structure will replace the aging 29-foot timber bridge built in 1950. The opening for the stream will increase from about 28 feet to about 45 feet, Smith said. That will give the stream slightly more room to shift around during heavy flows.

Work will begin July 18 and wrap up around December, according to the schedule. Seabeck-Holly Road, the main route to and from Holly, will be reduced to one lane during the construction.

The $1.67-million construction project will be carried out by Pacific Pile and Marine of Seattle. An artist’s rendering of the completed structure and other information can be seen on the Kitsap County website titled “Seabeck-Holly Road Bridge #20 at Anderson Creek.”

Hood Canal property will compensate for Navy construction at Bangor

Hood Canal Coordinating Council has finally found some shoreline property to compensate for environmental damage from the Navy’s $448-million Explosives Handling Wharf at Bangor.

The 6.7 acres of waterfront property — located near Kitsap County’s Anderson Landing Preserve on Hood Canal — becomes the first saltwater mitigation site in Washington state under an in-lieu-fee mitigation program. The $275,000 purchase was approved Wednesday by the coordinating council, which manages the in-lieu-fee program.

The Navy itself is not a party to the transaction, having paid the coordinating council $6.9 million to handle all the freshwater and saltwater mitigation required for the wharf project — including managing the mitigation properties in perpetuity.

The coordinating council’s in-lieu-fee program, which is overseen by state and federal agencies, allows developers to pay a flat fee for their environmental damage instead of undertaking mitigation work themselves.

New game lets you travel with wacky steelhead as they try to survive

In a new game open to everyone, 48 colorful cartoon fish will soon follow the wandering paths of real-life steelhead that have been tracked during their migration through Puget Sound.

Just like their counterparts in the real world, some of the young steelhead in the game will survive the trip from South Puget Sound or southern Hood Canal — but many will not. The game’s basic tenet is to choose a fish that you feel will be lucky or cunning enough to make it through a gauntlet of hazards from predators to disease. You then watch and learn about the needs and threats to salmon and steelhead as the game progresses over 12 days, beginning May 8.

Hood Canal nominated as Sentinel Landscape with ties to military

Hood Canal and its surrounding watershed have been nominated as a Sentinel Landscape, an exclusive designation that recognizes both the natural resource values and the national defense mission of special areas across the country.

If the designation is approved, it will bolster applications for federal funding to protect and restore important habitats and to maintain working forests in and around Hood Canal. Given the uncertain budget for environmental programs under the Trump administration, it wouldn’t hurt to have the Department of Defense supporting the protection of Hood Canal.

The Sentinel Landscapes Partnership involves the U.S. departments of Agriculture, Defense and Interior. The idea is to coordinate the efforts of all three agencies in locations where their priorities overlap, according to the 2016 Report on Sentinel Landscapes (PDF 5.6 mb).

Congress authorizes five restoration projects throughout Puget Sound

Five major Puget Sound projects have been given the provisional go-ahead by Congress in a massive public works bill signed yesterday by President Obama.

It seems like the needed federal authorization for a $20-million restoration effort in the Skokomish River watershed has been a long time coming. This project follows an extensive, many-years study of the watershed by the Army Corps of Engineers, which winnowed down a long list of possible projects to five. See Water Ways, April 28, 2016, for details.

In contrast, while the Puget Sound Nearshore Ecosystem Restoration Project (PSNRP) also involved an extensive and lengthy study, the final selection and submission to Congress of three nearshore projects came rather quickly. In fact, the Puget Sound package was a last-minute addition to the Water Resources Development Act, thanks to the efforts of U.S. Reps. Rick Larson, D-Lake Stevens, and Derek Kilmer, D-Gig Harbor, along with Sens. Patty Murray and Maria Cantwell.

The three PSNRP projects moving forward are:

Hood Canal awards honor local efforts to improve ecosystem

Mike Anderson, chairman of the Skokomish Watershed Action Team, and Thom Johnson, a leading expert in the recovery of Hood Canal summer chum salmon, have been named recipients of this year’s Hood Canal Environmental Awards.

Other recipients of the awards, which are sponsored by Hood Canal Coordinating Council, are Shore Friendly Mason and Shore Friendly Kitsap, two programs that actively enlist waterfront property owners in the protection and restoration of their shorelines.

I learned this afternoon that the awards ceremony on Nov. 4 will be dedicated to Rich Geiger, the longtime district engineer for Mason Conservation District. Rich, who died unexpectedly on Sept. 22, held the “technical vision” for the restoration of the Skokomish River watershed, according to Mike Anderson. (See Water Ways, Oct. 8.)

New protections planned for Devils Lake and Dabob Bay natural areas

In 1991, accompanied by botanist Jerry Gorsline, I visited Devils Lake for the first time. I remember being awestruck — in part by the beauty of the place but also because of the many unusual native plants that Jerry raved about. Not one invasive species had reached this place.

“Visiting Devils Lake,” I wrote, “is like stepping back in time, perhaps 200-300 years, to a period when civilization had not yet carried the seeds of foreign plants to the Pacific Northwest. At one end of the lake lies an enchanted world — a rare bog, where the sound of distant bubbles accompanies each footstep in the spongy moss.”

Jerry worried that telling the story of Devils Lake would bring irresponsible people to the lake, people who could destroy the fragile ecosystem. But he also worried that not telling the story would lead to a massive clearcut on this state-owned land and that this wonderland would slip away. You can read this story online in Chapter 10 of the book “Hood Canal: Splendor at Risk” (PDF 5.2 mb).

Jerry and others were successful in limiting the logging, in part because of increasing environmental awareness and a new program called the Timber, Fish and Wildlife Agreement. In 2002, 80 acres containing the lake were permanently set aside as a natural resource conservation area.

Now Public Lands Commissioner Peter Goldmark wants to add another 415 acres to the NRCA before he leaves office. The added property, now held in trust for state school construction, would extend the protected habitat to the western shore of Quilcene Bay. To gain special protections, the land would need to go through a process to compensate the trust for the loss of land and timber values.

Nearby, the 2,771-acre Dabob Bay natural area — which includes the highly valued natural area preserve and the surrounding NRCA — would increase by 3,640 acres under the expansion plan. About 940 acres is held by the state in trust status. Private lands, totaling 2,700 acres, could be purchased by the state but only from willing sellers.

Basic details are provided in a fact sheet from DNR (PDF 318 kb). Peter Bahls, executive director of Northwest Watershed Institute, wrote an article about the plan for Olympic Forest Coalition.

Two public meetings have been scheduled at Quilcene High School to discuss the plan:

  • Informational discussion: Wednesday, Sept. 28, from 6 to 8 p.m.
  • Public hearing for comments: Thursday, Oct. 13, from 6 to 8 p.m.
  • Written comments: Information available at the link above.

Information on the previous Dabob Bay NRCA expansion and request for related funding can be found in the DNR publication “Dabob Bay Coastal Conservation” (PDF 12.3 mb).

Close call, but Hood Canal may escape a major fish kill this fall

With some luck, southern Hood Canal may avoid a major fish kill this year, as we observe extremely low oxygen levels beginning to dissipate.

oxygen

It looks like the fish around Hoodsport dodged a bullet on Friday when south winds pushed the surface layer of oxygenated water to the north, bringing hypoxic waters up from below, according to data from the Ocean Remote Chemical Analyzer (ORCA) buoy near Hoodsport.

University of Washington researchers watching the conditions issued this alert on Friday: “Hypoxic waters have been observed intermittently at the surface at our Hoodsport mooring — in addition to the Twanoh mooring —consistent with the strong southerly winds and upwelling conditions we’ve been seeing over the past few days.”

Seth Book, who monitors the water conditions for the Skokomish Tribe, said he was on vacation last week and did not make his usual rounds to observe potential fish kills. But we have not heard of any reports of dead or dying marine life along the shores of Hood Canal.

The risk of a fish kill is still present, and another strong wind out of the south has the potential to bring more low-oxygen water to the surface. The layers of water and the timing appear similar to last year, when south winds brought deep-water fish — such as ratfish — to the surface, as Seth recorded in a video. See Water Ways, Sept. 1, 2015.

depth

Each summer, sunny weather brings a growth of phytoplankton that eventually dies, sinks to the bottom and decays, a process that consumes oxygen. The result is extremely low levels of oxygen near the bottom of Hood Canal, a situation that continues until a surge of seawater in late summer or fall pushes in from the Pacific Ocean.

Because of its higher salinity, that seawater comes in along the bottom and pushes up the low-oxygen water, which gets sandwiched between the ocean water and the more oxygenated water near the surface. If the surface layer gets displaced suddenly by the wind, the fish have no place to go to get oxygen. That appeared to be the condition on Friday, but now the middle layer is growing thinner as it mixes with the layers above and below.

Conditions are improving, Seth confirmed, “but the negative side of me still says we have low D.O.” Crabs, shrimp and deep-water fish may be out of the woods for this year, thanks to higher levels of oxygen in the incoming seawater, but mid-level fish are still at risk until the water column equalizes to a greater extent.

In July, areas farther north in Hood Canal, such as Dabob Bay, experienced low-oxygen conditions, which drove a variety of fish to the surface, Seth told me. Of particular interest were thousands of Pacific herring trying to breathe by staying in the upper foot of water along the shore.

“We have dodged something so far this year,” Seth said. “I am hopeful because we are now into September and we can see this intrusion continuing.”
