The tug and barge Albert and Margaret had been riding at anchor in the Toledo area when Tuesday's report moved them to the George Gradel terminal on the Maumee River, arrived to load gasoline. That is a precise errand: a fuel barge alongside a river terminal means a run is being planned to somewhere, even if no destination was logged.
A gasoline load at an inland river dock sits at the short end of the logistics chain. The barge is committed the moment loading starts, and nothing in Tuesday's data suggests it was still waiting.
Also out of Toledo on Tuesday: John G. Munson departed for Port Inland and Stenheim left for Hamilton, thinning a waterfront that had been crowded most of last week.
Monroe: Undaunted with Pere Marquette 41 departed Tuesday for Port Colborne, finishing the gypsum turn that began with their arrival from Alpena on Monday.
Marblehead: Dorothy Ann and Pathfinder arrived Monday to load limestone at Amrize, and by Tuesday's report were anchored in Lake Erie. A limestone pair sitting offshore after a loading call is worth scanning from the Ohio shore this morning.
Toledo, Midwest Terminals: Blair McKeil, Federal Asahi, and Wilf Seymour with Alouette Spirit appear in reports on all three days from Saturday through Tuesday. That is three confirmed data days at berth; a cold front crosses Erie on Friday, and any vessel meaning to move has Thursday as the cleaner window.
Lake Erie reads 3.26 feet above Low Water Datum at Cleveland, the highest among the upper four lakes. Ontario stands higher still at 3.80 feet at Rochester. Michigan is at 2.29 feet, Huron at 2.19 feet, and Superior is the lowest of the five at 1.90 feet. The Erie reading gives loaded vessels working the southern ports reasonable draft margin this week, ahead of Friday's front.
A cold front will cross Lake Erie on Friday before high pressure at 30.00 inches returns Saturday; waves are running 2 feet on Erie, Huron, and Ontario today. Lake Michigan is calmer at 1 foot as high pressure drifts southeast into the Ohio Valley. A separate front is expected through the broader region Thursday. Wednesday and Thursday are workable days on most of the chain; anyone scheduling a Friday Erie crossing will want to check the timing of that front.
Steve Hughes grew up in Marquette watching ore boats work the docks while his father, a Northern Michigan University geography professor, pointed them out from shore. Three decades later Hughes holds the wheel of the M/V Paul R. Tregurtha, the longest vessel operating on the Great Lakes, and retires in December. 'The distinction is more symbolic than operational,' he said. Every freighter watcher starts as a kid on a dock learning which stack is inbound.
