Thunder Bay Runs the Keweenaw, Due at the Soo by Mid-Afternoon

The Thunder Bay is working the Keweenaw corridor this morning, last reported at 02:12 with an ETA of 14:47 at the Soo Locks. That puts her at the chamber in mid-afternoon, a clean Wednesday run down Lake Superior if the 29.8-inch low sliding east toward Quebec keeps its distance.

She is not alone in the queue. The Calumet, upbound out of Detour, was due at the locks by 08:36. The Joyce L. VanEnkevort and the H. Lee White were both sitting at or near the lock chamber before dawn, downbound, and the Mesabi Miner had cleared the locks just after 01:00. Five vessels moving through one set of locks before sunrise is a workmanlike September Wednesday. Thunder Bay's afternoon slot is the one worth watching from the south shore of Whitefish Bay today.

Harbor Notes

The Wilfred Sykes was upbound on the Detroit River at 03:32, tracking for Port Huron with an ETA of 10:16 at the Vantage Point. She should be visible from the Blue Water Bridge well before noon.

The Algoma Discovery was downbound through Port Huron at 04:24 and was tracking toward Detroit with an ETA of 10:00 at that waypoint, making a clean run in the opposite direction on the same corridor the Sykes is climbing. Two vessels, same river, same early-morning hour, opposite headings.

Seven ports picked up Robert J. Lewis Pacesetter Awards at the AGLPA conference in Chicago, including Ports of Indiana-Burns Harbor, Port of Monroe, and Port Milwaukee, recognized for increasing international cargo tonnage through the St. Lawrence Seaway compared with the prior year.

The Levels Ledger

Lake Erie leads the board at 2.88 feet above Low Water Datum at Cleveland, with Lake Ontario at 3.20 feet. Lake Huron reads 1.91 feet at Harbor Beach and Lake Superior 1.85 feet at Sault Ste. Marie, with Lake Michigan at 2.05 feet at Chicago. The spread between Superior and Erie is wide enough to matter to a load planner working the full length of the system.

Weather on the Water

Fog is the hazard on Lake Michigan today. Light winds and a humid air mass have NWS forecasters calling for areas of fog through tonight, with off-and-on thunderstorms possible as a cold front works through. Lake Huron's cold front may stall across the area Wednesday. Superior's low is tracking east and should reach western Quebec by Thursday morning. Waves are running at 2 feet on Superior, Huron, and Erie; 1 foot on Michigan.

Looking Astern

One hundred years ago last November, the City of Bangor ran hard onto a reef near Copper Harbor in a Lake Superior storm while carrying a cargo of new automobiles out of Detroit. The wreck itself was survivable. What followed was not ordinary: salvagers returned in deep winter to pull the cars from the grounded hull, one of the stranger recovery operations in fresh-water history. The Keweenaw Historical Society recently marked the centennial with a framed painting by Upper Peninsula artist Clyde Mikkola, donated to the society's maritime chairman, Mark Rowe.

Tomorrow's Watch If Thunder Bay holds her 14:47 ETA at the Soo Locks Wednesday afternoon, she should be clearing onto Lake Huron by evening; watch the Detour to Soo Locks AIS leg Thursday morning to confirm her southbound position.
Vessel Spotlight
The *Algoma Discovery*, downbound through Port Huron at 04:24 this morning, was tracking for Detroit with an ETA of 10:00 at the Dossin Museum waypoint. She and the upbound *Wilfred Sykes* were working opposite ends of the St. Clair corridor within the same predawn hour, a tidy piece of lower-lakes geometry on a Wednesday morning.
