“The great lakes form a large basin that holds the run off from a huge area of North America. Lake levels fluctuate, sometimes a lot, and mankind’s activities can influence the levels very little if at all.”

Going to have to disagree here, mankind can have a lot of influence in the lake levels as we have built locks, power plants, and alternatives in the path of natural waterways. By blocking waters from leaving we are influencing water levels.

Of course that has nothing to do with climate change. My understanding is that around 2013 the GVT started trying to raise water levels and it looks like they succeeded. But as usual they screwed it up.

You are correct about man’s ability to influence. See: The Aral sea.

That said, the last few years in Michigan have been wet, after a bit of a dry spell so a lot of bodies of water are higher than they have been for some time. Whether or not the Government tried to intervene, I don’t know but Nature sure did. Presumably to punish those who wanted to be very close to the water...

It’s the Canadian’s... seriously. Keeping Superior high, while not letting Niagara open.

The GL water levels fluctuate on a fairly regular cycle and have done so forever probably, but certainly as long as we have been able to measure. Ultimately “locks and power plants” have nothing to do with it. All the water eventually ends up in the Atlantic Ocean. Some years it rains and snows more than other years. that’s about it.
