Today is the day. Given the mild and relatively ice-free winter on the Lakes, today’s opening of the Soo locks is a few days earlier than usual. Can you imagine another reason for the early opening, other than the weather? Answer follows.
It’s a good time to note which Great Lakes boats transited these locks most last season. The results are as follows:
Lee A. Tregutha made 92 transits, making her the most frequent vessel through the locks. She is quite the survivor too, delivered as tanker USS Chiwawa during the early years of WW2.

Second place greatest number of transits was Hon. James L. Oberstar with 88 transits.

With 86 transits, Edwin H. Gott was third. She was also the first vessel to pass through the locks at the beginning of the 2023 season; see the ice cubes in the lock at this time last year. Any guesses on te first cargo vessel to transit today?
A glance on AIS will tell you, and a glance today and again in 10 days will show very different pictures on Lakes traffic.

Fourth place for number of transits in 2023 was Paul R. Tregurtha with 81 transits.

American Century transited 76 times, making her fifth.

John G. Munson was sixth with 75 transits.

If you’re needing to know the entire top 10, here’s a link with that information.
And what additional impetus is there for opening a few days early? The steel producers. More info here.
First through the Soo for 2024? See who’s first in the queue as of 0530 today?

Here’s Joseph, as photographed 10 months ago approaching the Soo from Superior side.

Indiana Harbor will be next. The first ATB through will be Dirk S. VanEnkevort, as it looks just before posting, since they’re already in the St Marys River.

Technically, the first vessel through transited already yesterday, a Canadian icebreaker named Risley, on its way up to Thunder Bay.
I transited a dozen times or so in 2023, but I will likely do that zero times this season. June 28, 2024 is Engineers Day, a good day for a behind-the-scenes view. I will however be gallivanting soon. Watch this space.
All photos, any errors, WVD.
It turns out that today the whole system opens as well. More here. On opening day on the Welland Canal, top hats are presented to the captains of the first upbound and downbound vessels through the Canal. Navigation to the Twin Cities on the Mississippi began on March 17 for 2024.
