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
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.)
Chum salmon are beginning to make their way into Central and
South Puget Sound, which means the orcas are likely to follow.
Given this year’s dismal reports of chinook salmon in the San
Juan Islands, we can hope that a decent number of chum traveling to
streams farther south will keep the killer whales occupied through
the fall. But anything can happen.
On Oct. 2, orcas from J and K pods — two of the three Southern
Resident pods — passed through Admiralty Inlet and proceeded to
Point No Point in North Kitsap, according to reports from Orca
Network. The whales continued south the following day and made
it all the way to Vashon Island, according to observers.
On Tuesday of this week, more reports of orcas came in from
Saratoga Passage, the waterway between Whidbey and Camano islands.
See the video by Alisa Lemire Brooks at the bottom of this page. By
yesterday, some members of J pod were reported back of the west
side of San Juan Island.
The movement of chum salmon into Central Puget Sound began in
earnest this week, as a test fishery off Kingston caught just a few
chum last week, jumping to nearly 1,000 this week. Still, the peak
of the run is a few weeks away.
The Encyclopedia of Puget Sound has published the final two
parts of a seven-part series on shorelines, bulkheads and nearshore
As we researched the series, I was able to interact with a lot
of interesting people — from coastal geologists to property owners.
Today’s experts in shoreline ecology credit the late Wolf Bauer
with many of the ideas that have become commonplace in shoreline
restoration. I was pleased when Washington Sea Grant produced a
video tribute to Wolf, who died in January at 103 years old.
One story I wrote, which was published today, involved a boat
ride along the eastern shoreline of North Kitsap, which was the
perfect setting for describing the geology and natural forces that
shape the shoreline. I must thank Hugh Shipman of the Washington
Department of Ecology and Paul Dorn of the Suquamish Tribe for
their expertise. Check out “Sources of
On an earlier boat ride, I joined up with a group of shoreline
property owners who were learning about nearshore ecology and the
benefits of bulkhead removal. The boat trip, sponsored by the Shore
Friendly Kitsap program, is part of a pilot project to introduce
the idea of removing bulkheads.
The tour departed from Brownsville and went up through Liberty
Bay near Poulsbo, where we observed a mixed assortment of houses
and associated shoreline structures. Some of these waterfront homes
were protected with massive rock bulkheads; some featured stubby
wooden walls; and some were surrounded by vegetation with no
bulkhead at all.
“Taking this boat ride lets you see what the natural shoreline
should look like,” said Lee Derror, a Tracyton resident who has
been contemplating whether to remove her bulkhead, built of
Cost of removal is a major obstacle for many property owners —
unless their bulkhead is already failing. The other major concern
is whether alternative “soft shore” protection will be enough to
protect their shoreline from excessive erosion.
Leaving Liberty Bay, the boat headed to Port Madison on
Bainbridge Island to examine the Powel family property, where a
bulkhead was removed in 2013. The 1,500-foot bulkhead removal is
believed to be the largest private removal so far in Puget Sound.
Kitsap Sun, Aug. 29, 2013, or the Shore
Jim Brennan, a consulting marine biologist, told the passengers
that accommodations were made to protect a historic boathouse on
the Powel property by placing large rocks around the foundation.
Also, the beach was sloped back to absorb incoming waves. Other
than that, the shoreline is expected to eventually look much the
way it did in the 1800s, with a reconnected salt marsh providing
food and protection for migrating salmon.
Lee Derror told me that property owners should take a look at
their shoreline from the water side, especially if they plan to
remove their bulkhead. The Kitsap tour was especially helpful, she
said, “because you get to rub elbows with the experts.”
Kitsap’s Shore Friendly pilot project — one of five projects in
the Puget Sound region — will help property owners determine if
bulkhead removal is right for them. It includes with a visit from a
volunteer, followed up by an assessment from an independent
geotechnical engineer. The last time I checked, county officials
were hoping to offer additional boat rides in the future.
Below are the seven shoreline stories written by science writer
Eric Scigliano and myself for the Encyclopedia of Puget Sound and
the online magazine “Salish Sea Currents.” These are published by
the Puget Sound Institute, which is associated with the University
of Washington. Funding came from the Environmental Protection
Waterfront property owners are a special class of people, and I
mean that in a good way.
When it comes to sensitive shoreline habitat, they are the front
lines of protection. When storms cause property damage, they see
more than their share — and they pay handsomely for the privilege
in both the cost of property and taxes.
As I interviewed people and conducted research for a series of
stories on shoreline armoring, I came into contact with dozens of
shoreline property owners who were learning about the latest
science on the nearshore environment. They wanted to know how to
better manage their property. Some were contemplating removing
bulkheads where the wave energy allowed, knowing that many
bulkheads built years ago are not really needed.
The latest stories in our series, published in the Encyclopedia
of Puget Sound, are:
Although I believe that most shoreline property owners are
environmentally responsible, I do wonder about people who have
damaged shoreline habitats to improve their view or water access
without obtaining the required permits. It seems at every hearing
regarding shoreline regulations, somebody will speak up and say,
“It’s my property, and I can do what I want!”
One of the interviews that did not make it into the series was a
discussion I had with Jay Manning, a South Kitsap native who went
on to serve as an assistant attorney general, director of the
Washington Department of Ecology and the governor’s chief of staff
when Chris Gregoire was in office. Jay now serves as a member of
the Puget Sound Leadership Council, the governing body for the
Puget Sound Partnership.
Jay and I got to talking about how waterfront property owners
occupy a special place — literally and legally — when it comes to
protecting the public’s interest in shoreline ecosystems. A balance
of public and private rights is embodied in the state’s Shoreline
Management Act, which demands the highest level of protection for
water bodies and adjacent lands.
The public’s ability to enjoy natural resources along the
waterfront “shall be preserved to the greatest extent feasible,”
the act states. “To this end, uses shall be preferred which are
consistent with control of pollution and prevention of damage to
the natural environment, or are unique to or dependent upon use of
the state’s shoreline.”
As an assistant attorney general representing Ecology, Jay
learned that shoreline ownership embodies a special public-private
“It’s much more significant, I think, than what you find with
upland properties,” he said. “The full array of (private property)
rights that you find in upland areas does not apply to shoreline
State law builds upon the Public Trust Doctrine, an ancient and
enduring principle that retains certain rights to the public for
all time, regardless of ownership.
Jay, a shoreline property owner himself, says the Puget Sound
Partnership has identified the protection and restoration of
shorelines as a key element in the recovery of Puget Sound.
A few years ago, many cities and counties routinely approved
bulkheads without giving it a second thought. But that has been
changing as local jurisdictions adopt new shoreline master
programs. Now, one cannot get approval to build a bulkhead unless a
house is imminently threatened by waves or erosion.
So far, about half of the 12 counties in the Puget Sound region
are operating under the revised requirements, along with nearly 90
percent of the 101 cities.
Unfortunately, Jay noted, rules related to shorelines have never
been as rigorously enforced as those related to water quality, for
which the threats to human health are more obvious. Counties and
cities vary greatly in the amount of effort they put into land-use
For some people, it just seems easier to move ahead and get the
work done, thus avoiding delays and costs of permitting, consulting
work and mitigation. Some people don’t believe that shoreline
regulations make much sense.
But, as many local officials told me, they would like the chance
to talk with property owners about the value of shorelines, explain
the regulations and discuss various alternatives that might even
save money. Most regulations, after all, have a basis in science,
and we can all learn from what the latest studies are telling
It goes without saying that wood, rock or concrete bulkheads
built along the shoreline are not natural. They certainly don’t
look like any structure formed by nature. And when the water is
pushing up against them, waves bounce around and splash back
instead of rolling up on shore.
I have never had any trouble understanding some of the problems
caused by bulkheads. I imagine little juvenile salmon swimming
along the shoreline, working their way toward the ocean. In shallow
water, these little fish can stay away from the bigger fish that
want to eat them. But bulkheads create a stretch of deeper water,
where predatory fish can swim in close and devour the little
I’ve been told that bulkheads cause other problems as well, such
as blocking shoreline erosion. But isn’t that what they are
designed to do? What’s the problem? As I’ve learned — especially
over the past few months — natural erosion provides the sands and
gravels needed for healthy beaches. Natural beaches also collect
driftwood, which provides additional habitat for a variety of
As many readers know, I now work half-time for the Puget Sound
Institute, a University of Washington affiliate that publishes the
Encyclopedia of Puget Sound. We’ve been working on a series of
articles about bulkheads — formally known as shoreline armoring —
and I’m more convinced than ever that bulkheads really do cause
The first story in the series, released this week, describes the
effects of bulkheads on spawning habitat for surf smelt and sand
lance, two kinds of small fish that are an important food source
for salmon, birds and marine mammals. Check out my story, “Spawning
habitat for forage fish being lost to rising tides.”
As sea levels continue to rise, the high-tide and low-tide lines
move to higher elevations on the beach — until the high-tide line
reaches the bulkhead. For many bulkheads, the high-tide line is
already there. At that point, the rising sea level continues to
push the low-tide line to higher and higher elevations, reducing
the spawning habitat for fish that lay their eggs in the intertidal
This shrinking habitat is known as “coastal squeeze” or “beach
squeeze.” Recent studies suggest that where bulkheads are located,
Puget Sound could lose 80 percent of this spawning habitat by the
turn of the century, based on average predictions of sea-level
On beaches without bulkheads, the high-tide line would move
steadily inland, helping to maintain the critical habitat for
forage fish, according to Timothy Quinn, chief scientist for the
Washington Department of Fish and Wildlife.
“Everywhere in Puget Sound, there will be beach squeeze when you
don’t allow things to equilibrate on the land side,” he told me.
“What used to be exposed beach (during the tidal cycle) will no
longer be exposed.”
It turns out that many bulkheads constructed through the years
were never needed to prevent erosion, because they were built to
protect homes in areas where erosion is minimal. Future stories in
our series will cover this issue, including the prospect of
removing existing bulkheads to improve shoreline habitats.
Unfortunately, sea level rise adds a new twist to the discussion.
Still, the best advice when building a new house is to keep the
structure back from the water’s edge.
Meanwhile, this initial installment of the Shoreline Armoring
Series includes a nice piece by science writer Eric Scigliano
armoring’s effect on the food web.” In this story, Eric looks
at a broad spectrum of effects caused by bulkheads. He reports on
an involved study that focused on a series of paired beaches — one
with a bulkhead and one without — located in various parts of Puget
Most of the studies that we will report on during this series
were funded by the Environmental Protection Agency through grants
coordinated by the Washington Department of Fish and Wildlife. The
plan is to release about two additional stories each week over the
next two weeks.
Store plenty of water. That’s my first bit of advice for
earthquake preparedness. I suggest storing water for drinking —
enough to last a week — and maybe some extra water for washing and
If we’re going to prepare for an earthquake, let’s prepare for a
big one. Then we’ll be ready for smaller ones or even severe storms
with the potential to isolate us. Getting ready for an emergency
can help reduce the anxiety of thinking about a long power outage,
broken water pipes and other damage. Do what you can, then realize
that recovery will come, though it could take time.
If you would rather ignore the dangers, I guess that’s one
option for dealing with this kind of anxiety. But it could be a
costly approach, one ultimately filled with regret.
I recently had the privilege to be part of a team of reporters
who wrote about the effects of a 7.2-magnitude earthquake along the
Seattle fault. If you haven’t read the stories in the Kitsap Sun, I
urge you to take a look at “The
Danger Below Us.”
It may seem like a random number — 7.2 magnitude, large for any
earthquake — but people need to understand that this earthquake
would occur at or near ground level on a fault that runs through
the center of Kitsap and King counties. That’s essentially right
next door to hundreds of thousands of people.
Such an earthquake is not imaginary. It has happened before —
long before any cities were built. Where the fault broke free, the
land and seabed were raised upwards by more than 20 feet. Evidence
is still visible at the south end of Bainbridge Island, where a
submerged beach is now high and dry.
Most of us have heard concerns about the worrisome Cascadia
subduction zone earthquake, which raised alarms after the New
Yorker magazine described its potential effects. But for many
residents of Puget Sound, a quake on the Seattle fault could be far
worse, though probably less likely over the next 50 years.
The Kitsap Sun stories were based upon an earthquake scenario
developed by the Federal Emergency Management Agency and presented
to local governments in a “Draft
Risk Report.” A separate scenario for a 6.7-magnitude quake was
developed in 2005 by
Earthquake Engineering Research Institute, which modeled the
effects of fault rupture from Seattle through Bellevue to the
The death and destruction in either scenario is hard to imagine,
and who wants to think about devastation in this seemingly peaceful
part of the world? Keep in mind that even in a worst case, most
people will survive to rebuild and go on with their lives, as they
have in other parts of the world, including Japan. As we have
learned from other areas, being prepared can make a real
When I think about getting prepared, I begin with water. We
cannot live without it. The preparedness
list published on the Kitsap Sun’s website includes developing
an emergency plan for your family, addressing structural problems
with your house, learning first aid and several other things.
In the matter of the early-warning system, President Obama’s
proposed budget to Congress, released Tuesday, includes $8.2
million for the early-warning system. See the
news release from Sen. Patty Murray and Rep. Derek Kilmer.
A good explanation about how people might benefit from the
early-warning system is provided by Richard Allen in a presentation
Feb. 2 in Washington, D.C., called “The Resilience Summit.” This
issue is discussed in a YouTube video
from 7:40 to 14:00 minutes into the video.

By swimming the entire Green/Duwamish River in King County, Mark
Powell hopes to show that the river’s full length — roughly 85
miles from the mountains to Puget Sound — is a single system worthy
of protection and restoration.
I believe that most people have heard about the Duwamish
Waterway in Seattle, a channelized, industrialized section of the
lower Duwamish River where decades of pollution are being cleaned
up, one step at a time. But how much does anyone know about the
upper end of the river, which begins as a trickle of crystal clear
water in the Cascade Mountains south of Snoqualmie Pass?
“Almost nobody knows the river well, not even the people who
live along the river,” Mark told me.
Mark, the Puget Sound Program director for Washington
Environmental Council. said the idea of swimming the entire river
came to him during the kickoff of a new
Green/Duwamish Watershed Strategy by King County and Seattle.
The plan is to identify all the significant problems in the
PDF 1.1 mb) and to increase restoration efforts where
“I thought this would be an interesting way to connect with
people,” Mark said. “I’m a guy who likes to get outdoors, so this
is a personal commitment I could make.”
Mark swam around Bainbridge Island in the winter of 2008-09.
““By swimming the whole coastline, I’m not just diving to the
pretty spots. I’m forced to look at the gross parts,” he told
reporter Michelle Ma in a story for the
So far, Mark has been swimming the upper and middle portions of
the Green/Duwamish River. He said his biggest surprise is finding
pockets of good habitat everywhere he goes.
Earlier this month, he was accompanied on the river by Sheida
Sahandy, executive director of the Puget Sound Partnership, and
Martha Kongsgaard, chairwoman of the partnership’s Leadership
Council. A few days before they swam the river near Auburn, the
Leadership Council approved new “vitals signs” indicators for
“human health” and “human well-being” to emphasize the human
connection to the Puget Sound ecosystem. See
“Water Ways” July 30.
The human connection was still on Sheida’s mind when I talked to
her about a week after her trip to the Green River. The most
“eye-opening” part of the swim for her was the condition of “this
incredibly beautiful natural element coursing through a very urban
She saw evidence of people living along the river in
less-than-desirable conditions, she said. There were barbecues and
trailer houses but no suggestion that people had any connection to
the river — except that some individuals apparently were using it
as a toilet, she said.
“I haven’t quite wrapped my head around that, but it feels very
right that we are considering human well-being,” she explained. “On
the one hand is what we have done to the river. On the other hand
is what we have done to ourselves. We need to figure out how it all
Mark’s adventures on the river are chronicled in a blog called
Duwamish.” He hopes to swim every section of the river where he
is allowed to go and be safe. A portion of the Green River
controlled by the city of Tacoma has no public access, because it
is a source of the city’s water supply. Rapids in the Green River
Gorge are said to be dangerous, so Mark will look for a guide to
help him. And because of heavy marine traffic in the Duwamish
Waterway, he may use a boat to escort him on his approach to
Seattle’s Elliott Bay.
The Green/Duwamish River may be the most disjointed river in
Puget Sound, both physically and psychologically. People who have
seen the industrialized lower river find it hard to visualize the
near-pristine salmon stream spilling clean water down from the
mountains. It is the upper part that provides the inspiration to
clean up the lower part, Mark told me.
“If there was a reason for sacrificing a river, you could find
it in the Duwamish,” he said. “But we can’t afford to sacrifice
even one river. To me, this is what protecting Puget Sound is all
about. By the time the pollution gets to Puget Sound it is too
If salmon can make it through the gauntlet in the lower river,
they may have a fighting chance to spawn and produce a new
generation of Green River fish. Improving their migration corridor
is not an impossible dream.
I suggested to Mark that the name of the river be officially
changed to “Green/Duwamish” or “Green-Duwamish” to help people
recognize that this is a single river from the mountains to Puget
Sound. After all, the name “Salish Sea” has helped some people
realize that we share an inland waterway with Canadians. The other
name-change option would be to call it Duwamish all the way.
Until I started reading about the Duwamish, I didn’t realize how
this river once captured water from the Black River and the White
River as well as the Green River and the Cedar River. But the
system has changed drastically over the past century or so.
As you can see in the map on this page, the Green River once
joined the White River and flowed north, picking up waters from the
Black River. The Black River, which took drainage from Lake
Washington, picked up water from the Cedar River.
Where the Black River merged with the White River, it became the
Duwamish all the way to Puget Sound.
Two major events changed the rivers’ flow and subsequently the
nomenclature. In 1906, a flood diverted the White River to the
south into the channel of the Stuck River, which flowed into the
Puyallup River. Shortly after that, the White River was
artificially confined to keep it flowing south. Because the river
flowing north contained water only from the Green River, the name
“White” was changed to “Green” downstream to where the Duwamish
The other big event was the construction of the Lake Washington
Ship Canal in 1917 to connect the lake with Puget Sound. The
construction lowered the lake by more than 8 feet, with the lake
level controlled by the Hiram M. Chittenden Locks. The Black River,
which had taken the discharge flow from Lake Washington before
construction, then dried up. The Cedar River, which had flowed into
the Black River, was diverted into the lake.
Following those changes, the Green River and the Duwamish became
essentially the same river, with the total flow perhaps one-third
as much as it had been before the changes. If you are interested in
this history and other geological forces at work in the area, check
out the 1970 report by the U.S. Geological Survey
(PDF 53.1 mb).
It’s hard to describe the surprise I felt when I first glanced
at a new graph plotting bulkhead construction and removal along
Puget Sound’s shoreline since 2005.
On the graph was a blue line that showed how new bulkhead
construction had declined dramatically the past two years. But what
really caught my eye was a green line showing an increase in
bulkhead removal. Amazingly, these two lines had crossed each other
in 2014, meaning that the total length of bulkheads removed had
exceeded the total length of bulkheads built last year.
Not only was this the first time this has ever happened, it was
totally unexpected. Few people really believed that bulkhead
removal could exceed construction anytime soon. I was happy to
write up these new findings in the latest
newsletter for the Puget Sound Institute, where I’m now
“It was pretty shocking — in a good way,” said Randy Carman of
the Washington Department of Fish and Wildlife, who coordinated the
data based on state permits. “It makes me optimistic going
Randy helped develop the “vitals signs indicator” for shoreline
armoring, along with a “target” approved by the Puget Sound
Partnership. The target called for the total length of armoring
removed to exceed the total length constructed for the 10-year
period from 2011 through 2020.
Like many of the vital signs
indicators, this one for shoreline armoring was far from a sure
thing. In fact, like most of the indicators, the trend was going in
the wrong direction. Some people believed that the Puget Sound
Partnership was setting itself up for failure.
These were “aspirational” targets, Randy recalled, and meeting
them would be a tremendous challenge for many individuals,
government agencies and organizations.
As I described in some detail in the article for PSI, the number
of new bulkheads has declined, in part because of new government
rules. Meanwhile, the number of bulkheads removed has increased, in
part because of government funding.
But something else may be afoot, as pointed out by Sheida
Sahandy, executive director of the Puget Sound Partnership, and
David Price, habitat program manager for WDFW. A new “culture” may
be taking hold in which people realize that bulkheads are neither
good for the environment, attractive nor functional when it comes
to people enjoying their own beach.
When talking to shoreline property owners who have removed a
rock or concrete bulkhead, often the first thing they tell me is
how much nicer their beach has become. No more jumping or climbing
off a wall. No more rickety stairs. One can walk down a slope and
plop down a lawn chair wherever the tide tells you is the right
“The factors are all in place for a paradigm shift,” Sheida told
me. “When people see the geotech reports for their own beach, they
can see there is a different way. People can take off their shoes
and put their toes in the sand.”
Getting contractors and real-estate agents to understand and
support new methods of beach protection and restoration is one
strategy being considered. Personally, I was impressed with the
change in direction by Sealevel Bulkhead Builders. Check out the
story I wrote for the
Kitsap Peninsula Business Journal.
It takes a little land to create the right slope to dissipate
wave energy without any man-made structure. In some cases, large
rocks and logs — so-called “soft shore protection” — can help
reduce erosion. In some situations where land is limited and wave
energy is high, a solid wall may be the only remedy. No matter
which option is used, one must consider the initial cost and
long-term maintenance — including consideration of sea-level rise
caused by global warming.
“The secret,” said Dave Price, “is less about the strong arm of
regulation and more about helping people understanding what they
Scientific evidence about the damage of bulkheads has been
building for several years. Among the impacts:
Loss of beach and backshore, which reduces the area used for
recreation, shellfish, bird habitat and forage-fish spawning.
Loss of slow, natural erosion, which helps maintain the
quantity and quality of sand and gravel along the shoreline.
Alteration of wave action, which can impede natural movement of
sand and gravel and scour the beach of fine sediment, leaving
hardpan and scattered rocks.
Increased predation of juvenile salmon by larger fish where
high tides leave deep water along the bulkhead, plus fewer insects
for food caused by loss of shoreline vegetation.
Bulkheads can cause a coarsening of a beach over time, with
harder and harder substrate becoming evident. Damage from one
bulkhead may be slow and limited, experts say, but alterations to
more than 25 percent of the shoreline, as we see today, has taken a
serious toll in some parts of Puget Sound.
Dave told me about the time he stood next to a concrete bulkhead
and watched the tide coming in. Large fish, such as sculpins, were
able to swim right up to the wall.
“I stood there and watched these fish come right in next to
shore,” he said. “These were big fish, and they came up right next
to the bulkhead. There was nowhere for the juvenile salmonids to
get out of there.”
The cartoon below was part of this week’s “Amusing
Monday” feature, and it illustrates the situation that Dave
described. I could say much more about changing trends in
bulkheads, given new studies funded by the Environmental Protection
Agency, but that can wait for future blog posts.
I was eager to find out if a 32-foot fiberglass replica of a
killer whale could scare off a huge number of sea lions crowded
together on the docks in Astoria, Ore.
I kept telling my wife Sue, “It’s not going to work” — and I had
not the slightest idea that the motorized orca might capsize during
its attempt to frighten the persistent sea lions.
About 1,000 people were on hand last night when a human operator
drove the orca toward the sea lions, according to Associated Press
reporter Terrence Petty. A passing cargo ship created a wake that
rushed toward the shore and capsized the fake killer whale. And
that was that for now. You can read the story in the
I understand that the fake killer whale might be deployed again
against the sea lions in August, when their numbers are expected to
be high again. I still doubt that it will work — unless the
operators can find a way to aggressively approach the sea lions and
stay with the effort for an extended time. It might help to play
recordings of transient killer whales — the kind that eat marine
mammals. But my understanding is that transients don’t make many
sounds when they are in their hunting mode.
I readily admit that I’m not a killer whale expert, but let me
tell you why I believe that any sort of limited effort with fake
orcas will fail. It’s not that sea lions don’t fear transients. In
fact, if sea lions can be convinced that they are being approached
by a real killer whale, their fear level could be quite high.
I’ve heard from homeowners who live on Hood Canal, Dyes Inlet
and other shorelines that when transient killer whales are around,
seals and sea lions head for shore, climb up on docks and even
attempt to board boats to get away from them.
So I don’t know if the fiberglass orca will fool the sea lions
in Astoria, but does anyone think that these marine mammals are
crazy enough to jump into the water if they believe a killer is
there waiting for them?
