There has been more long term, social, ecological and cultural damage done by the dams in question than could be brought about by a dozen major pipeline projects. That a project was planned and executed sixty years ago does not dissipate the fact that the benefits from the undertaking all accrued to one party and the negative effects were borne by another.
In fairness to SaskPower they could not have foreseen the full extent of the ecological damage wrought by their development when it was undertaken. But that circumstance does not lessen the propriety of endeavouring to right that which is wrong.
