Welland Canal

Actually, there were four Welland Canals because navigating down the Niagara Escarpment that creates the Niagara Falls was very important before railroads were developed. Boats had to descend 326 feet [WellandLibrary] from Lake Erie to Lake Ontario. The following table that summarizes the canals is from WellandCanal-history. Please reference that link for details concerning the canals.

Welland Canal Facts First
Canal

Second

Third
Canal
(1887)
Fourth
Canal
(1932)
Number Of Locks 40 27 26 8
Width Of Locks 6.7m 8.1m 13.7m 24.4m
Length Of Locks 33.5m 45.7m 82.3m 261.8m
Depth Of Canal 2.4m 2.7m 4.3m 8.2m

Converting the numbers for the Fourth Canal from meters to feet gives us 859' x 80' x 27', which we can compare to the St. Lawrence Seaway that was built in 1959 at 740' x 78' x 26.5'. [Canal Dimensions] The current depth of the canal has been increased to 30'.

Bill Bird posted some pictures about the triple locks being shut down because of an oil spill. He also had some pictures showing that Lake Ontario was higher than normal.

1
Arrived Sunday to find the Welland Canal closed. It had been that way since Saturday afternoon. Federal Cedar is stuck in Lock 5 East.

2
The problem was an oil leak in the flight locks due to the malfunctioning of canal equipment. A boom was placed at the north end of Lock 4 east.

3
Workers test the water to make sure the spillage is contained.

4
Even when traffic resumed shortly after noon Sunday, Federal Cedar stayed put. Downbound ships used the west side of the locks meaning upbounders would have to wait. It wasn't until after supper that Federal Cedar would be underway.

5
Among those held up was Tim S Dool seen here entering Lock 7.

6
Dool had a cargo of iron ore for Arcelor Mittal Dofasco in Hamilton.

[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 know that speeding up the video (60x according to the comments) exaggerates the movement, but it seemed to bounce back and forth as it entered the first lock. At 6:22 a rolling bridge goes up after a train passes. Plus there are some lift bridges that we see go up.


Since the bridge and living quarters is on the bow, I think that makes it an old boat. But it has been remodeled because it has a self-unloader.

Then it occurred to me to Google it. I found a site that tracks marine traffic

I was wrong. It was built in 1967 as a self-unloader. The self-unloader has been upgraded a couple of times. The discharge boom can be swung 95 degrees in both directions.
At the time of her launch, the vessel was the largest capacity self-unloading vessel on the Great Lakes. Her unique squared hull design reduced wasted space thus increasing her tonnage. Her tall wheelhouse and forward accommodations has given her the distinction of being known as the "little bank building on floats"....With the exception of the converted steamer James Norris, the vessel is now the oldest self-unloader in the Upper Lakes fleet.
