How to get your rivers in the right place

[Gamerprinter]

I wonder if it will have any serious affect on Niagara Falls?

Actually, Niagra Falls was mentioned in that same show.

Apparently Lake Huron and Lake Erie didn't use to be connected. But with the rising of the Lakes caused the water to be forced over the land between the two lakes, which formed the rivers that joined the lakes. The connection between the two occurred 1800 years ago.

Water from the upper lakes flowing into Lake Erie then Lake Ontario caused the water to flow which eventually formed Niagra Falls. So apparently Niagra Falls is relatively "recent" (in geologic time). The show suggested that eventually the water volume flowing over Niagra Falls will increase, though it may be several thousand years before there's any real kind of disasterous change, due to that.
