Water levels in the Great Lakes are very touchy. There are many feet of difference between high and low water levels. Ive seen beachfront homes with the lakes lapping a few yards from their doors one year and a few years later the water is a football field away.

There might be knock on effects of fueling development in the Great Plains. With the proposed Canals/Rivers.

But development along Riverbanks in the central and Eastern U.S has been heavy in the ensuing Decades. So you’d need to clear a lot of territory. To account for the increased width of the Rivers.

Isn’t there technology to build desalinization plants to use sea water?

And I thought the Panama Canal project was an enormous undertaking.
