And a very good letter from last month about the high capacity wells, that took a while to get posted on the Guardian website:

Causeways back then, deep-water wells now
Letters to the Editor (The Guardian)

A Reader’s View

In the ongoing debate over deep-water irrigation wells was heard this comment: “We donʼt know what we donʼt know.” To some this comment would be profound, while to others inane.
It brought to mind a raging debate, of years gone by, over the provincial governmentʼs (of that day) decision to replace bridges and build causeways over the North and West rivers.
Avid fishers, hunters and others (my grandfather among them), voiced their strong opposition to the move, citing their great concern that such a move would kill the headwaters of these two important river systems, doing irreparable harm to the ecology of these two watershed areas.
The opposition voiced that the causeways would critically interfere with the tidal flushing of the rivers, flushings that were critical to keeping the headwaters alive and healthy, and by extension fish life and wild life alive and healthy.
The engineers and scientists, of the day, defended the governments move and voiced their ʻstudiedʼ opinions that no such harm would befall these two rivers headwaters, as the designed openings would be sufficient to allow the necessary flushing actions up the rivers.
Decades later it was determined that these headwaters were dead or dying, and something must be done to improve the flushing actions of the tides.
As a result the government of that day, acted to widen the spillway of the North River at Cornwall, and added a second bridge to the West River causeway, allowing greater
volumes of water to flow with the tidal actions
As a young teenager, father, my brother, and myself would fish off the bridge in Milton, catching some large and healthy trout. Alas, today the river in Milton is but a narrow stream compared to what it was 55 years ago.
What I have learned from all of this is that we are limited in our knowledge of things and there is much we (scientists included) have yet to learn and understand about all things. And, contrary to many expert opinions on this matter, nothing is absolute.
The opening statement, to me, is profound, and I say ʻnoʼ to lifting the ban on deep-water wells.
