Over the past two winters, there wasn鈥檛 much ice cover on the Great Lakes. That changed with this month鈥檚 deep freeze.
Frigid temperatures have frozen more than 40% of Lake Erie鈥檚 surface, according to the National Oceanic and Atmospheric Administration or NOAA. Scientists there 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鈥檚 polar bear at Edgewater Beach, and prevented a ship from Cleveland Harbor without the Coast Guard鈥檚 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 15th.
The St. Lawrence Seaway typically closes December 31st, but that closing has been delayed鈥y ice.
鈥淭he vessel Federal Biscay was held up in the Snell Lock specifically, because the lock itself had frozen due to cold temperatures,鈥� said Coast Guard Lieutenant Junior Grade Kyle Maxey. 鈥淲hat that鈥檚 done is had a couple backups in vessels transiting out of the Seaway.鈥�
The Seaway won鈥檛 close for the season until 5 ships including the Federal Biscay clear out. After January 15th, Great Lakes shipping will be over until March, when the Soo Locks and the Seaway open for a new season.
The , 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 scientist Ed Verhamme.
鈥淚t鈥檒l 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,鈥� said Verhamme.
With parts of the lake already frozen over, ice fishing has already . Lt. jg. Kyle Maxey says safety is key when ice fishing 鈥� and advises folks to remember the acronym 鈥� Information, Clothing, and Equipment.
