Restoring an ancient Great Lakes fish
- Editor H2ONotes [ 5/24/2013 - 04:33 ] #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
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
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
- Editor H2ONotes [ 5/24/2013 - 04:27 ] #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
- Editor H2ONotes [ 5/22/2013 - 05:26 ] #
Another one of those uh-oh moments related to Lake Erie, its fish and its fishermen was
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
- Editor H2ONotes [ 5/22/2013 - 05:25 ] # A $200 million backlog in Great Lakes harbor and channel dredging would end with a bill that just passed the U.S. Senate.
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
- Editor H2ONotes [ 5/22/2013 - 05:23 ] #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...
Work done at ex-brownfield site on Detroit River

industrial site along the Detroit River, officials announced Saturday.
Wayne County, the U.S. Fish and Wildlife Service and others have been
working for nearly a decade on the restoration of the Detroit River
International Wildlife Refuge Gateway in Trenton. more...
Great Lakes water levels: How did April's rain raise Lake Michigan and Huron, and what is the forecast?
- Editor H2ONotes [ 5/9/2013 - 06:24 ] #
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
U.S. Senate could free up money for Great Lakes dredging
- Editor H2ONotes [ 5/9/2013 - 06:20 ] #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.
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
- Editor H2ONotes [ 5/9/2013 - 06:16 ] #
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
- Editor H2ONotes [ 5/6/2013 - 06:23 ] #
Spring runoff has caused an overflow of untreated sewage and water
from Washburn’s treatment plant reservoir into Chequamegon Bay.
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.
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
- Editor H2ONotes [ 5/6/2013 - 06:22 ] #
What makes a pretty Great Lakes shoreline?
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
- Editor H2ONotes [ 5/6/2013 - 06:21 ] #More signs of spring in Orleans County as Lake Breeze Marina prepared
more than 100,000 king salmon to be released into Lake Ontario.
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
- Editor H2ONotes [ 5/6/2013 - 06:21 ] #
Lake Superior won’t be robbed to help boost water levels for Lakes
Michigan and Huron, even under a new water-level management plan that
goes into effect later this year.
That was the word Monday from
officials of the International Joint Commission, a Canada-U.S. board
that has authority to regulate water levels and resolve water use
disputes on the Great Lakes. more...
Study indicates Asian carp may already be in Great Lakes
- Editor H2ONotes [ 5/6/2013 - 06:19 ] #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
