Marianne Jackson, a personal trainer and yoga teacher, lives in
a fairly typical residential neighborhood in Des Moines, about
halfway between Seattle and Tacoma. Marianne has been interested in
gardening for years. Recently, however, she decided to up her game
by creating a backyard wildlife habitat.
That’s when Sarah Bruemmer, a habitat steward coordinator for
the National Wildlife Federation, entered Marianne’s life. Sarah
knows how to turn small outdoor spaces — or large ones, if
available — into functioning habitats. She coordinates a training
program that addresses issues from soils, gardening and invasive
plants to birds, butterflies and water quality.
Sarah’s month-long program, which includes weekly classes with
two Saturday field trips, is scheduled for April in Kitsap and
Thurston counties and May in Pierce County. Only a few seats remain
for the Kitsap training to be held in Silverdale.
Marianne, 56, took the course last year and came away with a
much deeper knowledge of the ecosystem. She had already ripped out
her grassy lawn years ago to create what became a series of
connected gardens, but the classes taught her how native plant
species and water features can help native birds and
“I already had the interest,” she said. “Now I have a lot more
knowledge that I can put to use. I’m planning to get my yard
Officials in Washington state’s Shellfish Program have
identified a clear pathway to meet a state goal of restoring 10,800
net acres of shellfish beds to a harvestable condition by 2020.
The 10,800-acre target, established by the Puget Sound
Partnership, was considered overly ambitious by many people when
the goal was approved in 2011. Many still believe that the
shellfish restoration effort will go down in flames, along with
other goals, such as increasing chinook salmon and killer whale
populations by 2020.
In reporting on the Shellfish Implementation Strategy, a
document still under development, I’ve learned that the goal is
within reach if enough of the ongoing recovery efforts around Puget
Sound continue to make progress. Please check out my latest stories

in on the magic number in Samish Bay,” both published in the
Encyclopedia of Puget Sound.
Citing pollution problems in Puget Sound, an environmental group
is asking the Environmental Protection Agency to revoke Washington
state’s authority to enforce the federal Clean Water Act.
Environmental Advocates, based in Portland, says a review of
103 discharge permits issued by the Washington Department of
Ecology shows a failure to control nitrogen pollution. Excess
nitrogen reduces oxygen levels in the water and triggers algae
blooms, resulting in serious problems in Puget Sound, according to
petition submitted to the EPA.
“Ecology determined that over 80 percent of the human sources of
nitrogen in Puget Sound comes from cities and towns, but it
continues to issue discharge permits as if it were completely
ignorant of these facts,” Nina Bell, the group’s executive
director, said in a
“It’s just flat out illegal to issue permits that contribute to
harmful pollution levels,” she added. “These permits are the
walking dead, existing merely to create the impression that the
state is doing its job to control water pollution when it is
One of the goals established by the Puget Sound Partnership is
to improve freshwater quality in 30 streams throughout the region,
as measured by the Benthic Index of Biotic Integrity, or B-IBI.
Simply described, B-IBI is a numerical measure of stream health
as determined by the number and type of bottom-dwelling creatures
that live in a stream. My latest article published in the Encyclopedia
of Puget Sound describes in some detail how this index works.
Here’s the basic idea:
“High-scoring streams tend to have a large variety of ‘bugs,’ as
researchers often call them, lumping together the benthic species.
Extra points are given for species that cannot survive without
clean, cool water. On the other hand, low-scoring streams are
generally dominated by a few species able to survive under the
Because benthic invertebrates have evolved over time with salmon
and other fish, many of these important “bugs” are primary prey for
the fish that we value highly. Said another way, “healthy” streams
— as measured by B-IBI — tend to be those that are not only cool
and clean but also very good habitats for salmon.
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
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.
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
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 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
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.
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
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.
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
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
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.
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
“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
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
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
