Highly recommend using the Great Lakes Bathymetry page, much better detail on lake depths, as well as shape files and data :)

Lake Ontario (The dot that says "Toronto" is the airport. Toronto the city continues well to the east, and the water intake pipes go out into the lake in the section where it gets very deep very quickly, almost as if they planned it well or something):

Lake Michigan near Chicago (Chicago has two active municipal water intake cribs, both about 2.5 miles out into the lake. The water is only about 30-40 feet deep at those points):

Detroit's water is similarly brought in from an intake a few miles off the shores of Lake Huron. Similar depth of 30-40ft.


Yeah. The Great Lakes generally aren't very deep near the shore. Toronto is really lucky. If Mississauga or Oshawa wanted to build the same system, they would need pipes 2-3x further into the lake!

The only other Great Lakes city I can think of that could replicate this kind of system without too much trouble would be Traverse City, MI. The Grand Traverse Bay is ridiculously deep. Of course, they don't have any need...


> Toronto is really lucky.

Not if you want to go swimming and there’s any wind at all!
