Soo Ice Jam of 1953, shared by John Rodawn
The Ludington Daily News from April 9, 1953 had an article titled Try to Clear Soo Lock Ice with Freighters’ Backwash that said:
SAULT STE. MARIE MICHIGAN – Three powerful lakes craft churned their propellers in a huge “Operations Backwash” today hopeful they could clear the Sault locks of an ice jam which has lied up nearly one-third of the Great Lakes fleet. The Coast Guard icebreaker Mackinaw was joined by the Pittsburgh Steamship Company freighter Arthur Anderson and the Canadian freighter Manladoc (not sure this is the right name) in the operation. Shipping men and lock engineers decided on the maneuver after an aerial survey showed the Whitefish Bay area, above the locks, was entirely free of the ice formation which has passed into the proper.
The three craft were tied up side by side at a dock and then went into action, with the propellers turning at full speed to churn up the water. Officials were hopeful the backwash would push the icy mess about 800 feet upstream, against the current, and get the ice in a position so it would be caught in a cross – current and washed over the Soo Rapids and out of the locks area. Coast Guard Commander T. A. Dahlburg of the Sault area expressed belief the ice would be cleared by this weekend, perhaps as early as Friday. Dahlburg reported 90 lake craft were tied up above the locks awaiting passage, while 64 were tied up below the locks upward bound. He called it the largest concentration of shipping ever assembled in the Sault area.
Under Dahlburg’s plan to keep some traffic operating, only the most powerful of the lake freighters and carriers were permitted to make their way downbound through the icy slush in the American locks. The only upbound traffic yesterday was through the Canadian lock, seven vessels passing through while 17 came down on the U.S. side.
