why not start the pipe line from one of the great lakes

Canada will veto that. Also Mn, Wisc, Michigan, Ohio, Penn. and NY. There's a town in Wisc, about 10 miles from lake Michigan but outside the lake's drainage basin, they were not allowed to pipe water from the lake.

Well we have a little treaty among the states in the watershed and Canada that forbids it for one thing.

“why not start the pipe line from one of the great lakes”

There are treaties with other states and Canada that detail how much water can be removed from the Great Lakes.
At the moment treaty name escapes me ( I am too lazy and dislike google too much) to google the treaty.
