These are Locks 4, 5, 6 and 7 of the
Welland Canal.
We are looking upbound (South) on the
Welland Canal and from Lake Ontario to Lake Erie. Lock 4 is the one nearest to us and Lock 7 is the one "on top of the mountain" in the center.

The flight locks in the Welland Canal provide a look at leading engineering and vessel traffic efficiency. Locks have hands free technology to guide the ship, real time monitoring and traffic management and are a wonder to view from the Lock 3 museum.

John Duguid: The flight locks raise or lower ships to the height of the Niagara Escarpment, the same geological formation Niagara Falls flows over a few miles to the east. |

While the Seaway Locks are shutdown, they are inspected, repaired and any worn parts are replaced. The locks usually reopen around the last week of March, allowing ships to resume travel between Lake Superior and other Great Lake. |

[There were no informative comments. It appears to be entering the downstream lock of the two-flight locks. I wonder how often they do "left-hand" running.]

I wondered why both sets of miter gates are closed in the above photo. I checked, that is not standard practice now.

Viking Octantis is approaching/entering lock 7 on May 1, 2022. These are just few pictures that I’ve taken that day. It was hard to pick a few.
[I believe the ship is entering Lock #6 from #5 and the photos was taken from #7. It was obviously taken with a long telephoto lens thus the length of the lock looks rather short.] |

EAST SIDE OF WELLAND CANAL REOPENED - June 8/22 4pm
A few of you noted yesterday that a number of ships were in anchorage waiting to go upbound in the Welland Canal. The reason - CN Rail is doing maintenance on
Bridge #6 closing the east side of the flight locks for a few days. The delays are continuing today as work is still in progress - will update later.
Photos taken by Captain
Alain M. Gindroz yesterday downbound on Americaborg through the Welland Canal.
Thanks Captain! Safe sailing today!
Tom Goodyer: I wonder who pays for the “waiting charges?” Charter rates for ships have gone through the roof! A 8500 TEU container ship is in excess of $100,000 per day.
Glynn R Green: Tom GoodyerThe same people who pay for delays for highway construction and for bridge crossings to US...
[The Seaway does close in the Winter. That is when maintenance is supposed to be done.]

Lock 4 West - (15.07.22).
Ever wonder what it looks like when a lock is filling?
We will raise 14m (46’) in this lock. The total lift of the eight canal locks is 99m (325’).
The locks are filled/emptied by gravity. There are no pumps.
These are a couple of screenshots from that video.

[Container ports on the Great Lakes is a rather recent development. I wonder which port this is headed to. Or will it off load the containers at multiple ports?]

Two interesting lockages in just a few days.
Wendy Vetter
posted three photos with the comment: "Yeah, got to see the second lock gate coming thru lock 7 , very impressive, what a feat that must be, got to love those tugs. I was told they were spares, stored underwater by lock 2 if my memory serves me correctly."
Andrew Carr: Its also hooked up to an air compressor and gets purged out every few hours incase any water has been taken on.
Ryan Ransom: Lock gates are generally hollow and float to a degree as otherwise the load on the hinge pivots would be too great.
Frank Kar: The lock gates are stored at the drydock just south of the wall. They are flooded and submerged to help preserve them. When needed they are partially filled with compressed air to float them to transport. There is a special crane in the St. Lawrence/ Montreal area to lift them into place for a change.

Todd Santos: When you motor into it and can see that your 55ft tall masthead is below the height of the lock doors, it really gives a sense of scale. The whole thing is an engineering marvel.

The Welland Canal was constructed to carry ships from Port Weller on Lake Ontario up over the escarpment to Port Colborne on Lake Erie. In fact this is the 4th canal because as ships got bigger, they had to make bigger canals to accommodate them. Locks 4, 5 and 6 in the current canal are twin locks and are an impressive engineering feat. Today John set up his tripod and was able to capture ISADORA "climbing the mountain" as well as OCTANTIS coming downbound. Be sure to watch OCTANTIS slide at the end to line herself up for her next maneuver! This is 2 hours compacted into a little over 2 minutes so don't blink or you will miss the Go Train.

Ben Hardie: Great shots 🙂 Why does lock 7 have 2 sets of gates at each end? And what is the reasoning behind what looks to be unnecessarily complex, curved gates?
Frank Kar: Ben Hardie The curved gate were developed for use in ice. Ice can't get behind them so they don't jam up as easy. The double regular gates are a back up system. Should 1 set fail they are still able to control the water and move ships. There used to be an emergency gate south of lock 7 galled the "guard gate" but was removed to speed up movement when the double gates at lock 7 were finished. The section of canal between lock 8 and 7 is full year round because it supplies water to many industries and the drinking water for St Satharines, Thorold area.
