Icy Great Lakes Causes Concern for Shipping, Safety

Over the past two winters, there wasn’t much ice cover on the Great Lakes. That changed with this month’s deep freeze.

Frigid temperatures have frozen more than 40% of Lake Erie’s surface, according to the National Oceanic and Atmospheric Administration or NOAA.  Scientists there  predict ice cover could jump to almost 90% by Sunday. This time last year, ice barely covered 2% of the lake.

The ice and cold temperatures cancelled a local group’s polar bear  plunge at Edgewater Beach, and prevented a ship from  entering Cleveland Harbor without the Coast Guard’s assistance.

With about two weeks left in the shipping season, the U.S. Coast Guard is working to make sure the Soo Locks (which connect Lake Superior to the lower Great Lakes) are clear before they shut down January 15 th.

The St. Lawrence Seaway typically closes December 31 st, but that closing has been delayed…by ice.

“The vessel Federal Biscay was held up in the Snell Lock specifically, because the lock itself had frozen due to cold temperatures,” said Coast Guard Lieutenant Junior Grade Kyle Maxey.  “What that’s done is had a couple backups in vessels transiting out of the Seaway.”

The Seaway won’t close for the season until 5 ships including the Federal Biscay clear out.  After January 15 th, Great Lakes shipping will be over until March, when the Soo Locks and the Seaway open for a new season.

The  Lake Carriers Association, an organization of companies that operate ships on the Great Lakes, says that while the Coast Guard is doing a great job with the ice, the region still needs another icebreaker to lighten the load for the cutters currently in service.

The good news, according to the Carriers Association, is that cargo was up this shipping season.

According to NOAA, ice cover typically peaks in mid-February.  The early ice on Lake Erie could affect wildlife and algae as the year continues, says  LimnoTech scientist Ed Verhamme.

“It’ll be interesting to track this particular year in icing so early and how long is this going to last and potentially affecting spring plankton blooms and going to the blooms this summer,” said Verhamme.

With parts of the lake already frozen over, ice fishing has already  started.  Lt. jg. Kyle Maxey says safety is key when ice fishing – and advises folks to remember the acronym  ICE – Information, Clothing, and Equipment.
