That is a dangerous place to be as the St Clair River is not all that deep. While deep enough for Ocean Going and Lake Freighters it has to be dredged to maintain the shipping channel. The ships propellors may look small but are huge and would make mince meat out of any item caught in their flow.

Diving in any river with active shipping is not without its risks. especially where the shipping channels have to be dredged just to keep them deep enough for the traffic.
Where I hated doing work diving was in marinas on lakes. Boat owners can be some of the filthiest humans on the planet when it comes to disposing things from their boats while docked in their slips A lot of times the water is murky with near zero visibility and you may encounter anything from bed springs to to broken bottles. rotting sail sheets fishing lines and hooks ropes and cables and every once in a while you might actually get lucky and find someone's clothes with a wallet full of cash or a gold neckless

isn't there supposed to be diver below markers? (blue and white from memory) - and boats/ ships have to stay away from the said markers....

I learned about red ones with a white diagonal stripe, and that's the question I wanted to ask. That aside, I love how clear the water is.

Now, I'm confused.

Dive Flags explained.. What Is A Diver Down Flag - Diving Info

Now, I'm confused.

As I understand, the red with white diagonal flag is the marking for the diver; the blue and white (alpha) flag is the marking of a boat that is accompanying a diver.

If the diver is swimming from the shore, he might have his 2' x 3' diver flag on a small float. The laker captain is 10 or 15 stories above the water, and 1000 feet away when the bow of his boat is even with the diver. The laker is a Vessel Restricted In Its Ability to Maneuver because of its size and the channel.

The diver must be a fool if he is counting on the captain even seeing him, or being able to alter course if he does see him.
