McCarthy Leads, Humbergracht Closes: Three Saltless Hours at the Soo

By Chris Izworski  ·  Founder, Great Lakes Gazette  ·  Sep 5, 2026
A foreign-flag salty bookends two Lakers on the downbound Keweenaw run while BBC Leer pushes upbound from Detour.

The downbound board at Sault Ste. Marie today reads like a domestic run until the last name on the list.

Walter J. McCarthy arrives first, AIS putting her at the locks by 12:38 p.m., last fixed at 11:02 p.m. Friday after running the Keweenaw through the night. Whitefish Bay follows ninety minutes later, ETA 1:51 p.m., last reported at 1:03 a.m. Saturday. Then, at 3:50 p.m., comes Humbergracht, a foreign-flag vessel last logged at 2:14 a.m., still with the better part of the Keweenaw transit ahead of her when most lock-watchers were asleep.

Those three ETAs stack a Saturday afternoon worth attending. McCarthy and Whitefish Bay are familiar names on this corridor; Humbergracht is not. Salties running the upper lake on a September Saturday are not a daily occurrence, and she closes the downbound sequence when the light is still good enough to read her stack.

From the upbound side, BBC Leer was due in from Detour by 6:30 a.m., last reported at 2:33 a.m. Joseph L. Block followed at an 8:35 a.m. ETA. John G. Munson had already cleared just before 1 a.m., giving the Soo a full card across the early hours.

Harbor Notes

Joyce L. VanEnkevort, not to be confused with the Clyde S. VanEnkevort we tracked through Monroe on Wednesday, was upbound in the St. Clair River early this morning, last fixed near Grassy Island at 12:32 a.m. with a Port Huron ETA of 6:59 a.m.

American Integrity is running downbound on Lake Huron, last reported near Harbor Beach at 3:26 a.m. Saturday with a Port Huron ETA of 8:12 a.m. Robert S. Pierson is roughly four hours behind her on the same water, due at Port Huron around 12:54 p.m.

At Duluth, Algoma Endeavour cleared the Superior Entry outbound, last reported at 4:38 a.m. Saturday. CSL Laurentien was inbound at the same entry, last reported at 12:38 a.m.

In the Welland Canal, Thunder Bay cleared Port Weller outbound at 3:50 a.m. and Sea Eagle II followed at 4:59 a.m., both now into Lake Ontario.

The Levels Ledger

Lake Ontario leads the board at 3.31 feet above Low Water Datum at Rochester, with Lake Erie close behind at 3.20 feet at Cleveland. Lake Michigan reads 2.17 feet at Chicago, Lake Huron 1.90 feet at Harbor Beach, and Lake Superior 1.62 feet at Sault Ste. Marie. The 1.69-foot spread between Superior and Ontario is the load calculation every upbound captain carries across the system; there is draft headroom on the lower lakes, less so on Superior.

Weather on the Water

High pressure building to 30.1 inches over Lake Superior through this afternoon holds through Sunday night, with a brief further ridge to 30.2 inches Monday. Waves are running one foot on Superior. Lake Huron is seeing cooler northeast flow under an Ontario high, with calmer conditions expected Sunday into Monday; waves two feet. A cold front has moved south of Lake Erie, high pressure at 30.20 inches filling in steadily; one-foot waves. Fog is possible over central and southern Lake Michigan after the frontal passage; one-foot waves there as well. Lake Ontario waves at two feet under a 30.1-inch ridge building from the north.

Looking Astern

One hundred years ago this November, the steamer City of Bangor grounded on a reef near Copper Harbor carrying new automobiles from Detroit, a cargo unusual enough to make the subsequent salvage famous. The Keweenaw Historical Society recently marked the centennial by receiving a painting from Upper Peninsula artist Clyde Mikkola depicting the wreck and the car recovery. The automobiles came off. The ship did not. Eagle Harbor still keeps the wreck on its list of local landmarks worth knowing before you anchor.

Tomorrow's Watch Watch for *Robert S. Pierson* to work through the Detroit River on Sunday; AIS placed her near Harbor Beach at 4:59 a.m. Saturday with a Detroit River ETA of 8:32 p.m. Saturday, putting her into Lake Erie by Sunday morning.
Vessel Spotlight
*Humbergracht* was last fixed at 2:14 a.m. Saturday running the downbound Keweenaw corridor, with a 3:50 p.m. ETA at the Soo Locks. She arrives after two Lakers have already cleared, which makes her the afternoon's closing act and, for watchers at the locks, the most unfamiliar name on an otherwise domestic downbound board.
