Hi all:
I went to the public info session that was held in Windsor in 2018. My unde=
rstanding is that there were 4 variations. All included a set of gates. The=
main reason is that if you stand on the causeway now during a really high =
tide and extrapolate the lake level to the land side you can easily see tha=
t it puts most of downtown Windsor underwater...... and with rising ocean l=
evels, compounded with Nova Scotia slowly sinking as a result of rebound in=
the centre of the continent from the geologically recent Ice Age, the prob=
lem would only get worse....

I haven't been able to follow this issue as closely as it deserves, so I
appreciate the submissions from Nelson Poirier and Fred Schueler. We
should definitely care for the 'fishes' before 'trucks and cars'; it
would seem logical. There is nearly always a way to do both if we care
enough. Yes?

This note is directed to folks who may be concerned about the Avon
River Causeway in Windsor. I lived in that area when the Avon River
flowed freely. It is been sad for me to see what has happened this
river with the erection of a causeway that reduced it to be
unrecognizable to the way Mother Nature designed.
A very similar scenario has taken place with the Petitcodiac River in
Moncton, New Brunswick with a well-intentioned causeway built in 1968
with fishway and adjustable gates to let the river flow. The huge
Fundy tides deposited silt that turned it into a barrier choking off
the river
* ...resulting in the extinction of the one Canadian population of a
rare Unionid mussel, Alasmidonta heterodon, the Dwarf Wedge Mussel,
because its anadromous host fish couldn't get past the causeway -

ublic-registry/cosewic-assessments-status-reports/dwarf-wedgemussel-apprais=
al-summary-2009.html
It took 42 years to get the causeway gates opened and now 52 years
later a bridge is to be completed within the year to let the river
flow free again replacing the causeway.
* ...but not allowing Alasmidonta heterodon to come back, because the
nearest surviving population is somewhere in southern Maine. The Avon
River Causeway should be forbidden not just for the harm it will do to
the Avon River's Salmon and other species, but as a memorial to the
loss of the Dwarf Wedge Mussel from Canada.
