Restoring an ancient Great Lakes fish

  #
Sturgeon have lived in the Great Lakes longer than humans have walked the earth. But the ancient fish now need our help to stay here. A joint project by the federal and state officials with a Native American tribe is trying to do that by rebuilding habitat for lake sturgeon in the Kalamazoo River. WMUK’s Brian Petersen went along to find out how it’s done.  more...

Lake levels won’t fix themselves

  #

An international group recently looked at the issue of low water levels and what could be done to try and amend the situation.

The Joint International Commission called for a study to explore the impact of placing inflatable gates or other devices in the St. Clair River at the southern end of Lake Huron as a way to stop outflow from the lake.

Officials say dredging, mining and other human activities eroded the river bottom in the last century, accelerating the outflow from Lake Huron toward Lake Erie. Lake Michigan is also drained via its connection to the other Great Lakes.  more...

Climb a Michigan dune and see it all

  #
When you dig your hands and feet into the sand of one of Michigan’s towering dunes, you’re participating in thousands of years of history.These enormous sand formations along the state’s Lake Michigan coast were formed, like the Great Lakes themselves, by glaciers dominating the land of 16,000 years ago. When those glaciers retreated and melted, they left behind the rocks and clay that eventually, through erosion, became the dunes.  more...

Heavy rains carry more phosphorous into Lake Erie

  #

Another one of those uh-oh moments related to Lake Erie, its fish and its fishermen was reported in The Dispatch last week.

Heavy rains this spring have washed an estimated 210 tons of phosphorous from farm fields inside the Maumee River watershed, Jeffrey Reutter, director of the Ohio Sea Grant Program, told an Ohio Senate Finance Subcommittee last week. Depending on future rainstorms, even more phosphorous could be heading toward Lake Erie.  more...

Federal Legislation Would Help With Great Lakes Dredging

  #
 A $200 million backlog in Great Lakes harbor and channel dredging would end with a bill that just passed the U.S. Senate.

There is a lot at stake economically when ships have to load light: carry less cargo, or risk running aground in the Great Lakes. Senator Tammy Baldwin (D-Wisc) says this bill will allow the Great Lakes to catch up on digging projects over the next six to seven years, putting the Great Lakes in better position to compete with the ocean ports. more...

Rising Lake Superior temperatures affecting fish species

  #
A new study shows that climate change could mean better conditions for some Lake Superior fish species, but worse for others.

Surface water temperatures on Lake Superior increased by about 4.5 degrees Fahrenheit between 1979 and 2006. That's one of the fastest rates of any lake on earth. The study by researchers at the University of Wisconsin shows that warming has created more suitable habitat in the lake for some fish, like Chinook salmon, walleye, and lean lake trout, but less favorable conditions for siscowet lake trout, a fatty fish that thrives in cold water. more...

Great Lakes water levels: How did April's rain raise Lake Michigan and Huron, and what is the forecast?

  #

The heavy rainfall in April did have a dramatic effect on the water level of Lake Michigan and Lake Huron.

The U.S. Army Corps of Engineers reports that the average level of Lake Michigan-Huron rose 5.16 inches from March to April.

That five inch rise is greater than the entire seasonal rise last year. Last year Lake Michigan-Huron only rose four inches from March to July.  more...

U.S. Senate could free up money for Great Lakes dredging

  #
The U.S. Senate may be closing in on legislation that could increase funding for dredging at harbors across the Great Lakes and the nation by freeing up more money from the Harbor Maintenance Trust Fund.

As the Free Press reported in March, the fund, which is paid for by taxes on the value of imported cargo, has built up a surplus of about $6 billion, even though the Army Corps of Engineers has a growing backlog of dredging projects.

That’s especially true along the Great Lakes, where there’s a backlog of about $200 million in dredging projects spread across 60 federally maintained harbors and channels, almost half of which are in Michigan.  more...

Cootes Paradise and other marshes benefit from Great Lakes low water levels

  #

Cootes Paradise hasn't had a massive regeneration since the '50s, the RBG's Tys Thysmeyer said.Low water levels in the Great Lakes are good news for marsh and wetlands like Hamilton's Cootes Paradise.

“It's a very good thing,” said Tys Thysmeyer, head of conservation at the Royal Botanical Gardens. “The wetlands around the shores do major regeneration of their reeds, things like cattails, when the water is low so they can generate from seed.”  more...

Big melt causes sewage overflow into Lake Superior

  #

Spring runoff has caused an overflow of untreated sewage and water from Washburn’s treatment plant reservoir into Chequamegon Bay.

Washburn City Administrator Scott Kluver said the city’s wastewater treatment plant has reached its limit, and the excess water is flowing into the holding reservoir. Normally, the excess in the reservoir would be treated after water levels go down. But runoff from the weekend’s warmer temperatures caused the reservoir to overflow for nearly four hours.

“Basically, what is happening is (that) because of the rapid snow melt, we have a large amount of water that is reaching into the sewer system,” Kluver said. “And so our flows that are entering the plant are triple or quadruple what they normally are.”  more...

Low water is high time to plant beaches

As lake levels drop and grasses and other plants sprout on once plant-free beaches, ecologists are encouraging waterfront property owners to see the splendor in that greenery.

“It’s important to try to get people to change their minds and see just how beautiful and wonderful native vegetation can be,” said Jennifer Gelb, restoration ecologist for the Tip of the Mitt Watershed Council, a nonprofit organization that serves four counties in Michigan’s northern Lower Peninsula. more...

Thousands of King Salmon to be Released into Lake Ontario

  #
More signs of spring in Orleans County as Lake Breeze Marina prepared more than 100,000 king salmon to be released into Lake Ontario.

In an effort to improve end of the season fishing, charter boat captains met on Wednesday to put 106,000 king salmon into pens to later be released into Lake Ontario.

"We are working in conjunction with the DEC to promote imprinting of our salmon into the Oak Orchard River," said Bob Songin, Charter Captain. "By doing that, we are stocking the fish in holding pens and we keep them in the river for three-to four weeks, taking care of them feeding them five times a day. Once they have imprinted, we take them out to the lake."   more...

Plan aims to stabilize Lake Superior water levels

Study indicates Asian carp may already be in Great Lakes

  #
Photo: kate.gardiner via Flickr.A new study released in April finds Asian carp may in fact be reaching the Great Lakes.  The Asian carp is an invasive species with an appetite large enough to potentially decimate the food chain ecosystem of the Great Lakes.  There have been many efforts to contain the spread of the fish in the Chicago Area Waterway System to connects to Lake Michigan.  The study now raises new questions about the effectiveness of that system.
