it was noted that major water supply reservoirs in southern Saskatchewan are mostly at or above normal levels.
I guess it all comes down to how "normal" is calculated.
I have no formal data, so what follows may be a waste of typing and reading.
It's true that, right now, the water level in Lake Diefenbaker seems to be in line with what I've come to expect over the last decade. But I've lived on and utilized this reservoir for over twice that period of time, and it seems to me that we have a clear trend of lower levels.
The mouth of the creek that I once used for docking my boat and for my subsistence fishing had not been reliably useful for at least 5 years. What I have been used to is that the lake "backs up" into the creek, and that just doesn't happen anymore.
In fact, the old-timers remember when the lake would regularly back up into the creek far enough to get something like a canoe up into my back yard, and I've seen that once in 2 decades.
