I have one small addition.
When Gardiner Dam and Lake Diefenbaker were contemplated, it was after the Great Depression and the dry period that had occurred. It was viewed as a drought-proofing project within Palliser's triangle. I think that's part of the reason why we continue to advocate for additional irrigation development. The water is there. The inflows are sustainable. This can help offset some of the concerns you raised in terms of challenges with a changing climate.
