What heavy ice coverage means for Great Lakes shipping and water levels

Ice formed on the Great Lakes early this year, thanks to the arctic temperatures we’ve been experiencing.

And that should be good for lake levels, which have plummeted in recent years. Right?

Well, it turns out the answer to that question is a bit complicated.

Lake levels are affected by a number of factors, including temperature, precipitation, evaporation and ice cover.

Spend a little over a thousand bucks and you too could capture some images that will grab the attention of your local TV station.

WZZM-TV in West Michigan featured a story about Hope College sophomore Jeff Zita.

Zita was curious about the ice forming on the lake and sent up his chopper. Here's the news segment (Click here if you can't see the video):

Local government leaders begin 3 day meeting on Great Lakes issues

A three day conference is getting underway in Marquette today, looking at the unique needs of cities on the Great Lakes and the St. Lawrence River.

More than a hundred American and Canadian cities are part of the group organizing the conference.

Dave Ulrich is the executive director of the Great Lakes and St. Lawrence Cities Initiative.

He says this year’s conference is focusing on the effects of climate change on Great Lakes cities, particularly on water levels on the lakes.

Record low lake levels spark dredging debate

Water levels have hit record lows on Lakes Michigan and Huron. Northport Bay on November 4, 2012.

You can listen to today's Environment Report here, or read the story below.

The U.S. Army Corps of Engineers has been recording water levels for almost 100 years. In January, the levels in the Lake Michigan and Huron system dipped to the lowest levels ever recorded.

That’s causing problems for commercial shipping and recreational boaters.

Peter Payette has been covering this story for Interlochen Public Radio and I spoke with him for today's Environment Report.

Payette said the issue that is front and center is the need for more dredging in the smaller harbors and marinas. He says they have not been getting help from the federal government - help that used to be there.

"Traditionally, it’s been the federal government through the U.S. Army Corps of Engineers that has dredged these channels to keep them open, and that has not been happening, and so now with the lake levels lower that problem is really being exacerbated," said Payette.

New report shows comprehensive view of climate changes’ effect

NOAA

A new report from the National Wildlife Federation details ways climate change is affecting the Great Lakes states, including Michigan.

The report says there’s more heavy rainfall events, a major decline in ice cover, and warmer average water temperatures. It outlines a number of examples where wildlife and communities are reacting to the changes.

Harbor Master in Leland "praying for snow and ice-cold temperatures"

Lakes Huron and Michigan are reaching record low water levels, and businesses along the Third Coast are feeling the effects.

Yesterday, Russell Dzuba, the harbormaster in Leland, Michigan (think Michigan's pinkie right on Lake Michigan), spoke with NPR's Melissa Block about what he's seeing out his window.

The low water levels have revealed a sand bar inside the Leland Harbor.

"...that ordinarily is not a good thing in a harbor," said Dzuba.

From the interview:

"We had an incredibly warm season - warm winter season last year, and we lost a lot of water to evaporation, and that takes place during the whole winter, as well as the summer.... Traditionally, we don't freeze as we did in the old days. It used to freeze all the way across the channel, 11 miles out to North Manitou Island. That hasn't happened here in a number of years."

You can listen to the interview here:

Last month, I posted on the low lake levels. If they continue to drop, which is expected, the low lake level record from March 1964 will be beat.

Study predicts less Great Lakes water loss

Previous research suggested a decline in future Great Lakes water levels, but findings from a recent scientific report may paint a different picture. 

Associated Press environmental writer John Flesher reports:

New research suggests climate change might not cause Great Lakes water levels to drop as much as previous studies have indicated. In fact, it might even cause them to rise.

Scientists at the NOAA Great Lakes Environmental Research Laboratory in Ann Arbor say they've devised a new way to predict future water levels. In a newly published journal article, they say it involves different methods of measuring evaporation of water from the soil and plants within the Great Lakes watershed.

Low water levels can cause heavy losses for shippers and other
Great Lakes businesses. They also affect the environment.

Raising Lakes Huron, Michigan costly

Water levels in Lake Michigan have been low for years. Would dams at the upper end of the St. Clair River raise lake levels, and would they be worth the cost?
Mark Brush Michigan Radio

TRAVERSE CITY, Mich. (AP) - A new report says it would be technologically feasible to raise water levels in Lakes Huron and Michigan to make up for drop-offs caused by more than a century of dredging and other human activity.

But the report obtained by The Associated Press says it would take decades to accomplish the task and the price tag could exceed $200 million.

The study is scheduled for public release Friday. It was conducted by a team of engineers and scientists for the International Joint Commission, a U.S.-Canadian panel that advises both nations on Great Lakes issues.

They're trying to determine whether it would be worthwhile to place underwater dams, gates or other structures at the upper end of the St. Clair River to reduce the volume of water escaping Lake Huron.
