Low ice covers effect on erosion
A lack of ice cover this year could lead to increased shoreline erosion, according to experts.
An analysis of Great Lakes ice coverage shows a decline of about 5% since the 1970s. In the last 20 years, 14 of those years had ice coverage levels below the 53% average.
Door County’s ice coverage
Lake Michigan has ice coverage of around 7 – 12% – a far cry from the 100% coverage we have experienced in our lifetime. These are new records for the Great Lakes.
The Great Lakes coverage is currently at a record low for January. Coverage is well below the seasonal average. The situation has prompted concerns about the environmental impact caused by the lack of ice.
What’s causing low ice coverage this year?
The low ice coverage results from local weather patterns. These patterns impact ice formation on the lakes. The warm air temperatures we all enjoyed earlier this winter have had an impact on ice formation. It has made for thin ice and a general lack of ice formation.
How low is the ice coverage?
Long term ice coverage has been around 50-55%, but this year it has hovered about 30 %. Even the Bay of Green Bay, at its narrowest locations, has not frozen entirely over. In the few areas where ice extends across the Bay, its total thickness is lacking.
Low ice affects the Great Lakes in many ways.
Remember, even when the ice is 100% frozen, it continues to “crack,” as anyone who has ventured out on the ice can tell you. If the ice completely covers the water, the chances of ice movements are minimal.
But, when the ice breakers open the shipping lanes south of Sturgeon Bay, it allows for ice movement.
Ice Damage
With strong winds, ice shoves develop and create havoc along the downwind shorelines. Once the ice begins to move, there is nothing that man can do to stop it.
A recent incident in the Sturgeon Bay area demonstrates what happens with strong winds. https://www.wbay.com/2021/02/04/large-crack-in-ice-strands-people-in-door-county/
The dangers of low ice – Shoreline erosion
Shoreline erosion is a real challenge without the protection of ice coverage. Ice prevents wave action from eroding the shoreline during the winter.
Winter winds cause wave action. Without the ice cover, wave action continues to wear away the shoreline.
Along the Lake Erie coast, shorelines have caved in due to the lack of ice cover protection. The waves keep slamming the shoreline. Ice calms lake water in the winter.
Another effect
Prevailing winds pick up more precipitation without ice on the lakes. It is then dumped on communities downwind.
Expect more occurrences of large snowfalls when lakes remain ice-free.
More Contaminates
Without ice cover, more suspension of run-off nutrients occurs. The lack of ice coverage results in the reintroduction of contaminants into the water. The long term effect is more algae blooms.
Low ice cover affects fish too.
Whitefish spawn in the winter months and need still waters, so their eggs are not disturbed.
What are the projections for the Door County Peninsula?
Projections for 2021 are for coverage of around 30 percent, sometime in February or early March. The long-term average is 53 percent.
Who benefits from low ice?
Lake freight is one of the few things that benefit from the low ice. It reduces the need for ice breakers to keep the shipping lanes open.
Good news
It’s not all bad news! The Great Lakes are resilient waters, and they do recover. Various pressure, including contaminants, invasive species, and algae blooms, assault the Lakes every year.
It may not be the same as it was, but there’s a lot of resiliency in the Great Lakes. The Great Lakes continue to bounce back and are still intact. They are an essential ecosystem.

Why are Welded Boat Lift Frames Superior?
Welds on Vertical Lift Frames
Welded boat lift frames are superior to the typical bolt-together structures found so frequently. There are several reasons for this.
Most of them center around the reduced maintenance, superior strength, and durability of welded lifts and canopy frames.
You spent good money when you bought the boat lift or canopy. Shouldn’t you get the best one available?
Why would you want to spend a weekend checking and tightening the nuts and bolts on your boat lift or canopy? We’re pretty sure you don’t.
In that case, why not purchase a high-quality boat lift or canopy, which has most of its critical components welded together.
ShoreMaster welded boat lift frames and canopies leave you free to enjoy your time away. Why waste any time tightening nuts and bolts. Your time is too valuable.
Quality starts with state-of-the-art welding.
Welded Frames = Less Maintenance
ShoreMaster welded boat lifts save you time because they require less maintenance and give you more strength.
Welded Boat Lift Frames Stay True and Square
Bolt-together boat lifts eventually become loose due to everyday use and prolonged periods of heavy waves striking the frame. Corrosion of the hardware only accelerates this process.
If you neglect to tighten a loose bolt on your boat lift, other parts of the boat lift such as the cables, pulleys, winch, or other components can wear prematurely.
A loose bolt will result in the frame shifting, which may result in a costly repair.
Loose bolts make it extremely difficult for you to discover the source of the failure.
How do you know when you have loose bolts?
A simple test is to push on one corner of the bat lift. If there is excessive movement in the frames, in particular forward and backward, you have one of two situations:
- One of more bolts are loose; or
- The lift is not sitting firmly on the bottom.
What about a canopy frame?
A welded boat lift canopy frame can save you hours in assembly time. Using just five bolts for a welded frame vs. dozens of nuts and bolts makes sense. A welded canopy frame adds more strength and rigidity to the entire boat lift also.
When it comes to assembling a boat lift, or canopy, you’ll be glad that you choose a welded product over a bolt together product.
Also, welded products take less time to assemble than a bolt together product.
Consider for a moment just one person can complete the assembly of a ShoreMaster canopy frame in as little as 30 minutes because the canopy frame includes only four all-welded components; two canopy ends and two canopy sides. Other manufacturers have dozens of parts that need bolting together.
ShoreMaster welded boat lifts do not require replacing frame parts caused by unusual wear due to loose, missing, or corroded welds. A bolt-together frame cannot say the same thing. ShoreMaster adds thick reinforcing plates on the frame structure when using bolts structure.
A Welded Boat Lift Offers Higher Resale Value
Because welds are permanent and require no maintenance, you will find that your welded-together boat lifts are more valuable at resale time. Welds will not rust or corrode like hardware. Potential buyers will be wary of the impending costs to replace worn out or corroded hardware.
