Soo Locks Passage Report Times

Unread post by Guest »

Years ago when newspapers printed the daily Soo Locks passage reports I used to collect these clippings. I was wondering how the time of the passage was recorded? Does anyone know how these were recorded? Were they recorded by an initial call in for the lock assignment, tying up in the lock, departing the lock, etc.?
