on the temperature/dew point spread.
If there is a nearby airport with weather
reporting information, it is easy to get an
idea of when the fog is about to break
up. For the Buoy 10 fishery, data from
the Astoria airport is a valuable tool for
figuring that out.
At first light, I check the weather at
the regional landing strip. It indicates
that the fog is thick this morning, with
visibility of less than an eighth of a mile.
The temperature is 13 degrees Celsius (55
degrees Fahrenheit) and the dew point is
the same. I reset the alarm for two hours
later and go back to sleep.
Checking the weather again, the
temperature is still 13 degrees but the dew
point is now 12, though visibility is still
an eighth of a mile. I keep checking the
“minute weather” for the airport (it updates
every minute) until the temperature/dew
point spread finally increases to 2 degrees
Celsius. Even though the fog is still thick,
I start driving towards Fort Stevens. With
the temperature now 14 degrees and the
dew point reading 12 degrees, it won’t be
long before the fog and visibility clear up
enough to see and be seen on the water.
The dew point tells us how saturated
the air is with moisture. When it equals
the ambient temperature, fog will be
present. When the spread increases by 2
degrees Celsius, or 5 degrees Fahrenheit,
fog will dissipate as ambient air temps
continue to warm.
Even though fog is still present,
visibility has increased to a quarter of a
mile. I launch into the fog with confidence
that it will soon be clear.
AFTER MY SCOLDING, the visibility does
quickly increase to a mile and the fog lifts
to a 300-foot ceiling of broken clouds. After
missing the first-light tide change, I hop on
the incoming conveyer belt at Buoy 20.
But the hunt for a Chinook between Buoy
22 and 20 off Trestle Bay does not go well,
and I don’t see any of the many boats that
surround me having any luck either.
I switch out my gear to target coho. I
trade out a 16-ounce cannonball sinker for
a size 001 Luhr Jensen Deep Six diver. Bait
is scarce in the river today, so I remove the
flasher and herring and switch to a red and
white spinner behind the diver.
The broken layer of clouds has now
dissipated as I troll with the incoming tide
along the green can line. By noon the sun
predominates, with the exception of a
mix of a few low-level cumulus and some
scattered wispy cirrus clouds high above. I
have not touched a fish and the incoming
current has picked up, pushing me further
upriver and well east of the Skippanon.
With clearer skies it is only a matter of
time before the afternoon winds will start
to pick up. The wind waves can get really
large in front of Youngs Bay, so I decide to
change course and troll into the current. It
takes an hour of hard paddling to get clear
of the area where large rollers will soon
be forming. I see glistening ripples in the
distance up ahead by Buoy 29. As I make
my way to it, debris mixed with grass mark
a rip current that has formed.
I quickly reel in my gear and cross over
the debris to its north side and then feed
out 25 feet of line. The drag is set as loose
as possible and the diver is adjusted to
trip at the slightest bump. Paddling into
the current I make little forward progress,
prolonging my presentation at the seam
of this rip.
IT’S NOT LONG before line starts peeling
off my reel. The expected rise of the line
is followed be an acrobatic show from a
well-fed late August coho. After promptly
landing and securing the fish and then
filling out the paperwork, I propel my
plastic vessel full steam ahead to stay clear
of the sea grass assembling parallel to the
rip zone. Again my reel’s drag is loosely set.
Line slips off with every paddle stroke as
I try to make headway into the opposing
current and wind. A second thick hatchery
coho attacks my spinner.
Coho are the trickster of the salmon
world with their ability to pull off twirling
headshakes while peeling out line, a tactic
that has left many anglers frustrated with
their disappearing act. I am spared from
the magic show. I cautiously play the fish,
waiting for my opening. The net is thrust
forward and my second dinner guest is
now safely tangled in the webbing.
With my limit secured, 20-mile-per-
hour westerlies and 2- to 4-foot wind
waves confront me as I prepare to head in.
I hastily stow my gear and start paddling.
The afternoon breeze more than doubles
the time it takes me to cover the 2 miles
back to the launch area, but with two coho
packed in a kill bag, it is worth it. NS
No doubt about it, with weather pushing in right off the ocean, heavy boat traffic and big tidal swings and currents, the big river’s
estuary can be hairy to fish out of a kayak, but a little knowledge about how fog burns off made it a safer one for Brenneman that day.
