I am not sure if this is completely true. I believe in some previous years (even last year), the snow mat was down while shipping season was still going on Lake Superior. The Portage Waterway sees almost no shipping traffic, except for the annual September visit of the lakes carrier bringing salt for the roads and an occasional ship during an autumnal storm.
What we really are waiting on is for the cities of Houghton and Hancock to bring in the snow. We are at their mercy as to when they will place the snow down there and then coordinate the grooming of that snow as they place it. I believe once the bridge is down in December, it is pretty much down for the season-regardless of what is happening elsewhere on the big lake.

That was the explanation in the Mining Gazette about the Coast Guard. I tried to find the article but it's already archived..
According to Keweenaw.info website. The mat will not be down until mid Dec. and the gates will remain closed until then..Here's the write up from last Friday.....
Current conditions:
The snowmobile trails from Twin Lakes to Copper Harbor are officially open, but groomers are not running yet due to low snow conditions. We will turn loose our fleet of groomers as soon as conditions change.
If you do choose to use the trails, be aware that there are rocks, stumps, branches and wet areas not yet covered by snow and hazards that have not yet been identified. Any trail usage should be done with extreme care until we have better snow cover.
There is logging on a short portion of Trail 133 between Gay and Lac La Belle. The protective mat on the Portage Lift Bridge between Houghton and Hancock will not be installed until the middle of December. The gates at the bridge will not be open until then either.
The Keweenaw Convention & Visitors Bureau asks that you stay on the trails, STAY OFF THE ICE, respect private property, do not drink and drive, and above all else, please, drive safely. The signs on the snowmobile trails are there for the riders’ safety. Please, DO NOT remove or destroy these signs.
