Tregurtha and Presque Isle Split the Midnight Lock, Open September

Two heavy downbounders cleared the Soo in the same dark hour; Cinnamon trails down the Keweenaw for an afternoon arrival.

September got its first two downbounders through the Soo before most people set an alarm. Presque Isle cleared the locks with an ETA of 00:11, its last ping logged at 00:01. The Paul R. Tregurtha followed eleven minutes behind on the clock, ETA 00:54, final position report at 00:44. Two of the bigger names in the fleet, through the same chamber, in the same midnight hour that turned the calendar.

Neither vessel announced itself with fanfare. The data just shows two position pings going quiet on the Lake Superior side and two ETAs ticking over on the Huron side. That is how the Soo works at the end of a long August.

The next downbounder in line was Algoma Discovery, rounding Whitefish Point at 3:58 a.m. with a 6:42 a.m. lock ETA. After her, Cinnamon is working the Keweenaw corridor with an ETA of 14:44 this afternoon, which gives riverbank watchers in the Soo a second appointment before supper.

Harbor Notes

Walter J. McCarthy, last noted queuing for the Soo on August 26, turned up upbound in the Detroit River at 3:23 a.m. today, with Port Huron listed as the next checkpoint at 11:20 this morning.

Saginaw, which we watched end her lay-up and head upbound on Huron a week ago, appeared inbound at the Welland Canal's Port Weller entrance with a 3:17 a.m. ETA this morning.

American Century took one of the last clean-up loads of coal from the Midwest Energy dock in Superior, departing for DTE St. Clair/Monroe. At least one more load of coal was reported remaining at that dock when the Century left.

In Toledo, John J. Boland arrived to load ore for Torco and Algoma Bear arrived to load coal at the CSX dock. In Monroe, New York/Double Skin 509A arrived to unload liquid asphalt at Michigan Paving and Materials. In Sandusky, Kaye E. Barker arrived to load coal at Norfolk Southern.

The Levels Ledger

Lake Ontario leads the board at 3.16 feet above Low Water Datum at Rochester, with Lake Erie close behind at 2.91 feet at Cleveland. Lake Michigan reads 2.18 feet at Chicago, Lake Huron 1.77 feet at Harbor Beach, and Lake Superior 1.69 feet at Sault Ste. Marie. The Erie and Ontario numbers give loaded grain and ore carriers comfortable clearance toward the Seaway. Superior's 1.69 figure is the tightest of the five; masters loading heavy at Duluth or the Twin Ports will carry that number all the way to the far lock.

Weather on the Water

Fog is the hazard this morning on Lake Michigan, where light winds and a humid air mass are expected to produce patchy fog again tonight as well. Waves are running one foot on Superior and Michigan, two feet on Huron, Erie, and Ontario. A low near 29.7 inches is drifting east across Ontario toward James Bay by Wednesday, pulling a cold front that the Huron forecast says is likely to stall across the region midweek. Vessels on Huron should plan for that front by Wednesday.

Looking Astern

The Keweenaw Historical Society marked the centennial of the City of Bangor wreck on Tuesday, accepting a framed original painting by Upper Peninsula artist Clyde Mikkola. The vessel was carrying new automobiles from Detroit when it grounded on a reef near Copper Harbor during a November 1926 storm. The salvage operation that followed was unusual even by Great Lakes standards: workers pulled cars one by one from a wrecked freighter in January cold. The painting was presented to maritime chairman Mark Rowe and will join the society's collection.

Tomorrow's Watch Watch for *Cinnamon* at the Soo locks by mid-afternoon; her AIS-posted ETA is 14:44 on September 1, and if she locks through on schedule she will be on Lake Huron by Wednesday morning.
Vessel Spotlight
The *Paul R. Tregurtha* cleared the Soo downbound in the opening minutes of September 1, logging its last position ping at 00:44 with an ETA of 00:54 through the locks. She came through just eleven minutes after *Presque Isle* cleared the same locks, putting two of the fleet's larger vessels on Lake Huron before the first hour of the month was gone.
