We signed up for a boat tour through the locks.
Entering the lock.
Almost in, see how low we are.
We are in and the water is beginning to fill. Water enters through gravity through 25 valves in the bottom of the lock, not that little bit of water coming through the closed lock you see in the picture.
.Full and opening, see photo above to compare how much higher we are, the gates that are now opening.
The lock fully open with the ST Mary's canal ahead.
The bridge joining the twin cities of Sault Ste Marine in the US and Canada
Arriving from Lake Superior into the Canadian locks for the drop back down 21 feet.
A really neat building along the locks in Canada
The lock is full. See the difference in the water levels.
The lock at the lower level
Leaving the Canadian lock
This is the tour boat entering the lock.
The ST Mary's rapids. A large amount of water still flows through the rapids. I believe we were told only 4% of the water goes through the locks.
This freighter is 750 feet long and going into Lake Superior. The viewing platform puts you right in the action.
Entering the lock with the lower gate open.
Not much room to spare
Starting to rise, note the photo above, the hull is even with the wall, now it is above
Upper gate open and the freighter leaving.
This freighter coming into the lock is 1000 feet long. Only one lock can handle a ship this size. There are plans to add another super size lock and waiting for Congress's to appropriate the money. I believe we were told this process started 10 years ago.
Note how much higher the ship is above the dock
Next Mackinac Island. Thanks for following along
