Good inputs.

We lived in a Redwood forest for 17 years.   The Salmon ran
in the river between various pine and sand on one bank and clay
and Redwood on the other.  Tan Oak and other Oaks put out Tanic acid
and the Redwood bark and sap drip is very toxic. (even to paint :-) )

I think what started them getting lost (not returning) was the METH
chemicals in the
water that changed the smell of the water for natural homing. Might be
the 'Mary Jane' juice from wild and planted plants of the North West.

I wonder the effect by Chlorine in water - HCL and various Sulfurs
from underground domes and what is poured on the land to change PH.

Thirty years ago or so - Dow Chemical was extracting (electricity) Chlorine
from the Mississippi river.  When the river level went down, they would
switch to their salt domes.  They produced Chlorine and caustic soda.
They could do this by generating their own power.  (I electronically
monitored the turbines from failure and Chlorine clouds that moved through
the facility upon a leak.  Signing your life away to do a consulting job
was not a fun day believe me.

I wonder to this day if other companies could be built on the river to
extract phosphates and package them back up to sell back to farmers and
home owners.  Maybe some day we will see that.

The Salmon normally are eaten by Eagles or Bear or man before massive
dye offs.  It is normal after years in the ocean growing and avoiding the
fishery boats - then home to spawn in the stream they were hatched or not
and then die.  The dye-out might be these 'lost' ones with smell that is
far to good and traps them at sea.

I suspect so much had changed few mature ones made it home.  And with the
fisheries closed down, how can new Salmon be made with that current river
smell.  Rivers cut into seams of chemicals and can also do bad towards the
river inhalants.

The famous one in the Physics community was a river in Africa that cut
into a massive rock forming pockets.  These pockets filled
with small rocks of Uranium and with time it went close to critical.  The
resultant chemicals (very toxic) were only found in bomb sites and labs.
The water moderated it for years and it was a concern upon discovery
the water might be lost - letting the piles of small beads to go critical.
It was extracted in small volumes and the region and ocean lived another
day.

Oregon would be prime due to the volcano blast changing the chemical mix
of all river basins there.  And likely eastward as the ash fell.

I'm not fighting - just adding more input.  World modeling is a very
complex design.  Issues thousands away effect local life.  The sulfur
acid rain killed many a forest.   My neighbor has burned several trailers
that contained a lot of plastic.  The runoff went into the creek that
borders and traverses my land only to kill trees and who knows what else.

Public announcements have gone out not to burn wire for the copper
(laws...)
and how dangerous it was to do so.  But people continue to do so.

Yet on another mode of thought :

The frogs and many other ground based animals including deer ticks (YES!)
were eaten up by fire ants.  I don't see slugs or land snails anymore but
I have tree fern and moss.  So generally the air and such is clean or they
would be gone.  I also noted the ant hills are changing - fewer but more
complex.  Multi-queen now in the mixing of the three species (sub or
otherwise)
of fire ants.  So land species of snail are ebbing out due to hungry
invaders.

Thanks David -

Now I'm thinking to much again!
