As part of today’s Earth Day commemorations, the Wisconsin Water Library at the University of Wisconsin-Madison, supported by Wisconsin Sea Grant, and the Wisconsin Library Association announced the books selected for a basin-wide shared-reading experience, Great Lakes, Great Read.

“The Water Walker” by Joanne Robertson is the children’s selection and the adult selection is “The Best Part of Us” by Sally Cole-Misch.

“The Water Walker” is the story of a determined Ojibwe grandmother, a “nokomis,” named Josephine Mandamin who walks to raise awareness of the need to protect “nibi” (water). Robertson wrote and illustrated the book, which was published in 2017.

Published in 2020, Sally Cole-Misch’s award-winning novel, “The Best Part of Us”, explores a family’s ties to an island in the Canadian waters of an inland lake just north of Lake Huron—how those ties are tested both through natural processes and family dynamics.A calm lake and an island in the background.

“The Great Lakes have shaped Wisconsin as we know it. These inland seas provide drinking water and fuel our agriculture, shipping, manufacturing and recreation,” said WWL Senior Special Librarian Anne Moser. “These two books will bring the lakes alive in new and evocative ways. We hope readers will reflect on the lakes and be inspired, become passionate and feel more connected to them.” 

WLA Executive Director Laura Sauser said, “All Wisconsinites are encouraged to read these titles, and we also hope to be a catalyst for libraries throughout the upper Midwestern states and Canadian provinces to engage patrons through a range of activities.”

Both selected authors will be featured in a free webinar series happening on Sept. 25 and Oct. 2 and 9. All events will start at 6 p.m., CT, and will be open to the public.

By Lily Cartier, University of Minnesota Duluth

Knowledge of the oceans is more than a matter of curiosity, our very survival may hinge on it.

–President John F. Kennedy

While this inspiring quote is about the oceans, the same could be said about two waterbodies that we know and love locally: the St. Louis River and Lake Superior.

But how much do we really know about these waters? Brandon Krumwiede, a Great Lakes geospatial coordinator for the National Oceanic and Atmospheric Administration (NOAA), told listeners at the March River Talk held at the Lake Superior Estuarium in Superior that what lies at the bottom has largely been unknown and unmapped.

Krumwiede said that full-fledged mapping of the St. Louis River Estuary was not undertaken until 1943, driven by World War II and the importance of local ship-building and steel production.

“It was really important to map out the river and the estuary so that we had safe navigation, commerce could commence, and all the vessels that were being built in the Twin Ports could be shipped overseas,” Krumwiede said.

After that, estuary mapping efforts languished. Currently, there is not a comprehensive modern picture of the St. Louis River Estuary or the Great Lakes. It is difficult to know the health of the plants, animals and water in the area without knowing what lies below the surface. 

Along with an assortment of government and local agencies, NOAA gained funding from the Great Lakes Restoration Initiative in 2020 for a project called the Collaborative Benthic Habitat Mapping in the Nearshore Waters of the Great Lakes. The team uses benthic habitat mapping to measure the water levels in the Great Lakes. The goal is to map any part of the Great Lakes that has a depth of 80 meters or less. As of now, the project has mapped about 13% of the Great Lakes. 

This underwater mapping is done through two different methods. The first is called “sonar,” a process that uses sound waves to map the area. This uses small survey boats that move up and down the area that is mapped. The second is called “lidar,” which stands for light detection and ranging. This mapping technique uses green lasers on vessels or drones to map the substrate.

“At night, with a bathymetric lidar survey, you[‘ll] see this plane spinning around a green laser all over the beach. It looks like a UFO,” Krumwiede said.

Both types of underwater mapping come with pros and cons – the main one being the reliance on good weather while the data is taken. As you can imagine, lake conditions in northern Minnesota and Wisconsin are not often optimal for boats and small vessels. This study has a short season of about May to early November, at the latest. 

Krumwiede wished they would have prepared better for the warm weather we had this winter. “This season would have been amazing. We should have had survey boats here year-round because we were ice-free,” he said.

Why is mapping the river and Great Lakes vital? 

“It’s really important to think about, how do we ensure that we get the data that’s needed to make sure we make the right decisions and manage these natural resources into the future. For our generation and future generations down the road,” Krumwiede said.

The final River Talk for the season will be held at 6:30 p.m. on Wednesday, April 10, at the Lake Superior Estuarium. Keith Okeson with the Lake Superior Chapter of Muskies Inc., will present, “Muskies and the St. Louis River.”

A team from the University of Wisconsin-Madison received a grant from Illinois-Indiana Sea Grant to study PFAS (per- and polyfluoroalkyl substances) messaging to water users in Wisconsin with a special focus on Latinos, since they are the largest and fastest-growing minority group in the state.

PFAS, sometimes called “forever” chemicals, are found in various products and can contaminate drinking water. High levels of PFAS have been linked to health risks, such as increased cholesterol levels, decreased vaccine response, risk of thyroid disease, lower birth weights and reduced fertility in women. However, health risks at lower levels are uncertain. Communicating these risks effectively to increase understanding, avoid undue fear and provide recommendations for behaviors people can do to reduce risks is crucial to the 70% of Wisconsinites who depend on municipal water supplies.

“The Wisconsin Department of Natural Resources now requires monitoring for PFAS in municipal water supplies and reporting when any are detected at over 70 parts per trillion,” said Lyn van Swol, principal investigator and a professor with UW-Madison’s Department of Communication Arts. “Given these new requirements and uncertainty about the health effects of PFAS, particularly at lower levels, public health educators are struggling with how to communicate with the public about the presence of PFAS in their municipal water supplies.”

Van Swol and the grant team will work to develop effective communication strategies about PFAS risks, focusing on engaging messages that encourage actions such as using water filtration systems. They will do this in three parts. First, they will gather data on people’s internet searches related to PFAS information. Second, they will test specific messages with municipal water users, and finally, test which messages engage social media audiences.

They will share their results via webinars, news releases and collaborations with Spanish-speaking media. The team will also develop resources for environmental and health communication professionals designed to enhance public understanding and proactive response to PFAS exposure in their communities.

The grant team is comprised of van Swol and Bret Shaw, professor with the Department of Life Sciences Communication and an environmental communication specialist with UW-Division of Extension; Gavin Dehnert, emerging contaminant scientist with Wisconsin Sea Grant; and Cristina Carvajal of Wisconsin Eco-Latinos.

Other partners include UW-Madison Extension, the Wisconsin Department of Health Services, the Wisconsin Department of Natural Resources, Public Health Madison & Dane County and the UniverCity Alliance.

The study is part of a larger project coordinated by Illinois-Indiana Sea Grant that addresses PFAS knowledge gaps in the Great Lakes region.

Released Goldfish Grow to Monstrous Size, Destroy Habitat

Original Story: Livia Albeck-Ripka, The New York Times

Inside a fishbowl, the goldfish — a species of carp native to East Asia, bred for aesthetic delight and traditionally believed to bring good fortune — is hardly more than home décor. Usually just a few inches long, it is among the easiest of pets to keep.

But released into the wild, the seemingly humble goldfish, freed from glass boundaries and no longer limited to meager meals of flakes, can grow to monstrous proportions. They can even kill off native marine wildlife and help destroy fragile and economically valuable ecosystems.

“They can eat anything and everything,” said Christine Boston, an aquatic research biologist with Fisheries and Oceans Canada.

Over the past several years, Ms. Boston and her colleagues have been tracking invasive goldfish in Hamilton Harbour, which is on the western tip of Lake Ontario, about 35 miles southwest of Toronto. The bay has been decimated by industrial and urban development as well as by invasive species — making it among the most environmentally degraded areas of the Great Lakes.

Their study, published last month in the Journal of Great Lakes Research, could help pinpoint goldfish populations for culling, said Ms. Boston, who is the lead author. “We found out where they are before they start spawning,” she said. “That’s a good opportunity to get rid of them.”

The fast-growing female goldfish, Ms. Boston noted, can also reproduce several times in one season. “They have the resources,” she added, “and they can take advantage of them.”

Goldfish were first spotted in Hamilton Harbour in the 1960s, but largely died off in the 1970s because of industrial contamination. In the early 2000s, their population appeared to recover. Goldfish can tolerate a wide range of water temperatures, reach sexual maturation quickly, and can eat nearly anything, including algae, aquatic plants, eggs and invertebrates, Ms. Boston said.

The feral goldfish are also destructive, uprooting and consuming plants that are home to native species. They help spawn harmful algal blooms by consuming the algae and expelling nutrients that promote its growth, Ms. Boston said, creating conditions that are intolerable to native fish.

To track the goldfish, the researchers captured and sedated 19 of the larger adults and surgically implanted tags the size of AA batteries into their bellies. The tags, which sent signals to acoustic receivers around the bay, provided researchers with a map of their locations.

Eight of the fish died, but the remaining 11 led Ms. Boston and her colleagues to find that the fish tended to spend the winter in deep waters and moved to shallower habitats by spring, where they prepared to spawn.

Some options for removing the goldfish, she said, include capturing them with specialized nets deployed beneath winter ice, or using “electro fishing,” which involves stunning the fish with an electrical current and scooping them from the water. Both techniques, she added, would avoid killing the native fish.

Nicholas Mandrak, a professor of biological sciences at the University of Toronto Scarborough, said that while goldfish were introduced to North America in the late 1800s, the wild population had begun to “dramatically increase” in the past two decades. Their spawning explosion, he said, resulted partly from people in densely-populated areas releasing pets in urban ponds.

Climate change may play a role, because of the goldfish’s capacity to adapt to warming and poorly oxygenated waters, he added.

“There are literally millions of goldfish in the Great Lakes, if not tens of millions,” Dr. Mandrak said.

Despite the threat, he added, environmental managers tend to forget the goldfish. “They just assume, ‘It’s been there for 150 years — there’s nothing we can do about it.’”

The problem is not unique to Canada. In Australia, a handful of unwanted pet goldfish and their offspring took over a river in the country’s southwest. Feral goldfish have flooded waterways in the United Kingdom, and, in Burnsville, Minn., the discovery of football-size creatures in a lake in 2021 led officials to beg their constituents: “Please don’t release your pet goldfish into ponds and lakes!”

People wrongly believe that because goldfish are “small and cute” they won’t pose a problem when released into the wild, said Dr. Ricciardi. “It’s the ‘Free Willy’ syndrome.”

Goldfish, he added, are just a small part of a vast invasion of non-native species whose outcomes can be unpredictable, and in some cases, are worsened by climate change.

“Under human influence, beasts are moving faster farther in greater numbers, reaching parts of the planet they could never reach before,” he said. “We’re talking about the redistribution of life on Earth.”

Anthony Ricciardi, a professor of invasion ecology at McGill University in Montreal, noted that not all invasive goldfish become supersized, but even the small ones are problematic, outpacing native fish populations and damaging the environment.

Their football-shaped bodies can swell to a size that makes them too large a meal for predators — up to about 16 inches long. “A fish would have to have a really big mouth to eat it,” she said.

Visitors to the Wisconsin Maritime Museum in Manitowoc can now get up close and personal with one of the Great Lake’s most infamous invasive fish, the sea lamprey. The new exhibit, entitled “Attack of the Sea Lampreys,” was made possible through a collaboration between Wisconsin Sea Grant and the Great Lakes Fishery Commission and tells the story of how sea lamprey were introduced to the Great Lakes, their impact and the ongoing efforts to manage them.

Chief curator Kevin Cullen and the education team revamped an invasive species lab on the museum’s lower level to house the new exhibit. The space was largely dormant and full of locked cabinets. Said Cullen, “People would just pass by it, so it became a really good opportunity to enhance a space that was already there.”  

The redesigned space provides a more interactive, sensory experience. Visitors can now open the cabinet doors to find answers to questions about sea lamprey, such as how many eggs they lay or bones they have. Content is written at a middle-school reading level, and many items are meant to be touched and handled, making the exhibit ideal for kids and families.

The irrefutable stars of the show, however, are the lamprey. Thanks to support and a custom-built tank from the Great Lakes Fishery Commission, museum-goers can enjoy watching over a dozen lamprey hanging out, their toothy maws suctioned to the side of the glass.

Cullen said initial feedback has been positive. “[Visitors] love it. I think they’re creeped out by these things and fascinated to see them.”

The creep factor is due largely to how sea lamprey feed. A parasitic fish, sea lamprey latch onto larger fish and suck out blood and body fluids. Their mouths are disc-shaped and ringed with rows of horned teeth to better grab flesh. Once suctioned onto a host, sea lamprey then use their sharp tongue to bore a hole in the fish, usually near its heart. A single lamprey can kill up to 40 pounds of fish.

For many, the story of sea lamprey is the stuff of nightmares—or at least a low-budget horror film. Titus Seilheimer, the fisheries specialist with Wisconsin Sea Grant who helped the museum secure the lamprey tank, hopes the exhibit helps visitors see another story.

“It’s one of the great success stories of invasive species management,” said Seilheimer.

Originally from the Atlantic Ocean, sea lamprey arrived in the Great Lakes via shipping canals, landing in Lakes Michigan and Superior by the 1930s and 1940s. By the mid-twentieth century, the lamprey population exploded, devastating the Great Lakes fishery and ecosystem. It wasn’t until the discovery of TFM, a chemical that selectively kills lamprey, that numbers decreased.

The population of sea lamprey is now 90% lower than what it was at its peak. But because lamprey can lay up to 100,000 eggs, that success is tenuous. Said Seilheimer, “If you take your foot off the gas, you see lamprey numbers increase.” Continuous management is required to keep the population in check.

The exhibit is a reminder of how humans have shaped and continue to shape the Great Lakes ecosystem. Said Cullen, “I hope [visitors] have a sense of responsibility when they leave that how they behave in the Great Lakes basin affects others.”

“Attack of the Sea Lampreys” at the Wisconsin Maritime Museum is now open to the public.

Wisconsin’s Busiest Boating Holiday; Help Prevent Invasive Species This July 4th

Every year, tens of thousands of Wisconsinites and visitors take to the water in early July to celebrate summer and the 4th of July, the state’s busiest boating holiday. Starting this summer, our long running Clean Boats Clean Waters Landing Blitz has been fulling incorporated into the Great Lakes Landing Blitz, joining all of the Great Lakes states and provinces in the effort to educate boaters that simple clean up steps and draining water from the boat and live wells can help to prevent the spread of aquatic invasive species (AIS).

In Wisconsin, from June 30-July 9, many boaters will be greeted at landings and access points by volunteers and regional aquatic invasive species prevention partners sharing the simple but powerful message: YOU can protect lakes and rivers form aquatic invasive species impacts. Clean Boats Clean Waters boat inspectors will give out a brand new red, white, and blue boat trailer sticker with a boat graphic showing people all the places where plants, tiny animals and potentially contaminated water can hide.

“It only takes a minute to remove plants, animals, mud or debris from boats, trailers and equipment and to drain all water from bilges, livewells and bait buckets,” said Erin McFarlane, the Statewide CBCW Educator with Extension Lakes. “These simple steps help keep invasive species from hitching a ride from one lake or river to another.”

Do your part to keep Wisconsin waters healthy and stop the spread of AIS by following these easy steps:

  • Inspect boats, trailers and equipment for attached aquatic plants or animals.
  • Remove all attached plants or animals and mud
  • Drain all water from boats, motors, livewells and other equipment.
  • Never move live fish away from a waterbody.
  • Dispose of unwanted bait in the trash.
  • Buy minnows from a Wisconsin bait dealer.

Following these steps helps boaters comply with Wisconsin state law which prohibits the transport of aquatic invasive species. To learn more about invasive species and their impacts to Wisconsin’s waters and economy, visit the DNR’s Aquatic Invasive Species Efforts webpage.

Great Lakes water levels could increase on average from 19 to 44 centimeters in the next few decades, study says

New research into Great Lakes water levels looks farther into the future to predict how much climate change will increase lake levels in four of the five Great Lakes.

The predictions for the levels between now and 2050 show average increases from 2010-2019 levels of Lake Superior rising 19 centimeters (7.5 inches), Lake Erie 28 centimeters (11 inches) and lakes Michigan and Huron by 44 centimeters (17.3 inches).

The Lake Michigan and Lake Huron waters governed by an 1836 treaty are at the heart of negotiations between Michigan, the federal government and Native American tribes to determine how much and what kinds of fish can be harvested by recreational, state-licensed and Native American commercial fishers. Much has changed since the treaty was signed, notably because of invasive mussels. But change created by human activity was underway even before the signatories to the Washington Treaty ink dried in Washington D.C. in March 1836.

Since the early 2000s fewer young whitefish have been making it to adulthood. Understanding the decline of lake whitefish recruitment is important for fishery managers and regulators as they approach the deadline to update a 2000 consent decree that regulates recreational and commercial fishing in Lake Huron and Lake Michigan.

How the shape of the Great Lakes now compares with their past is important as negotiators update the consent decree addressing commercial and recreational fishing interests in waters covered by an 1836 treaty. The deadline is at the end of June, the third such decree covering these contentious waters. The most recent one in 2000 was for 20 years, and it’s overdue for an update.

The impact that quagga mussels have on the Great Lakes food web gives deep meaning to the saying, ‘food for thought.’ These prodigious filter-feeders are implicated in the decline of many Great Lakes fish species, well beyond those with commercial and recreational value.

The food web in lakes Michigan and Huron has changed in ways that jeopardize age-old fishing traditions and raise questions about how we’ve managed them. Now negotiators are updating a legal settlement that spells out where and how much lake whitefish and lake trout can be harvested.

A free online video game for children about a Great Lakes shipwreck is now available. “The Legend of the Lost Emerald,” is a point-and-click adventure game designed for players grades 4-6. It was developed by the University of Wisconsin-Madison’s Field Day Lab in partnership with Wisconsin Sea Grant, PBS Wisconsin Education and the Wisconsin Historical Society. Teacher fellows offered insights at every step of the game’s development. Funding was provided by PBS Wisconsin Education with additional help from the Wisconsin Coastal Management Program and Sea Grant.

Players must use critical thinking and historical inquiry skills to find the wreck as they step into the shoes of Jules, a maritime archaeologist, with help from a cast of diverse family members. Players dive underwater to gather clues, build evidence and uncover the real treasure – stories of shipwrecks inspired by Great Lakes history. It takes two classroom sessions to complete (about 2 hours).

“The goal of the game is to connect students with the maritime history in their own state – to go beyond the story of the Titanic,” said Anne Moser, senior special librarian and education coordinator for Wisconsin Sea Grant. “It includes topics like lake ecology, maritime archaeology, trade and commerce.”

Even in water-rich Michigan, no guarantee of enough for all

By John Flesher, Associated Press

ALLENDALE, Mich. (AP) — Dale Buist knew running a commercial greenhouse would pose challenges. He just never expected a water shortage to be among them. Not in Michigan, with its vast aquatic riches.

Yet a couple of irrigation wells yielded only a trickle.

As the megadrought in the Western U.S. worsens, calls for freshwater diversions from the Great Lakes to the West have grown increasingly popular. Water diversion from the Great Lakes harms not only the ecosystem, but also the cultural significance of water, according to MIchigan environmental policy expert.

Online event will feature poet Moheb Soliman

Wisconsin’s Sea Grant’s “Lake Talks,” a series of informal presentations on science and humanities topics related to the Great Lakes, continues Thursday, Dec. 9, from 7-8 p.m. The evening’s event is titled “Place, identity and the Great Lakes region: A conversation with poet Moheb Soliman.”

The virtual event will be held on Zoom. It is open to all, though registration is required. (Register for this event now.) The hour will include time for audience questions.

Poet Moheb Soliman (photo: Melissa Lukenbaugh)

Soliman is an interdisciplinary poet from Egypt and the Midwest who has presented his work in the U.S. and Canada with support from numerous foundations and institutions. His first book of poems, HOMES (Coffee House Press, 2021), alludes to an acronym used to remember the names of the Great Lakes: Huron, Ontario, Michigan, Erie and Superior. Yet the title has other meanings as well, as Soliman’s writing offers an intimate perspective on an immigrant experience as he drives his Corolla past exquisite vistas and abandoned mines, through tourist towns and Midwestern suburbs, seeking to inhabit an entire region as home.

He will be featured in a conversation-style event with Senior Special Librarian Anne Moser of the Wisconsin Water Library. Moser is also the education coordinator for Wisconsin Sea Grant. Their discussion will be interspersed with Soliman reading from his work.

The cover of HOMES by Moheb Soliman (Coffee House Press, 2021)

Reviewing HOMES for EcoLit Books, Lillie Gardner praised the book as “stunning” and noted that “Soliman reflects on heavy topics with easy-going wit and candor.” She wrote, “An engaging meditation on our world and our place in it, HOMES takes the idea of borders as neat dividing lines and cracks it open, redefining place as a space that is shared and changeable.” To learn more about Moheb Soliman, visit his website at www.mohebsoliman.info.

For Lake Talks event and registration information, visit the Sea Grant website, or follow Wisconsin Sea Grant on Facebook or Twitter. You can register for Moheb Soliman’s talk now.

Great Lakes Breakdowns: There’s a thin line between affordable and not for boat tows

When the COVID-19 pandemic struck, millions of Americans suddenly found themselves out of work or working remotely, their recreational options severely limited with the closure of bars, eateries, gyms and countless public spaces.

So what better way to spend time with family while remaining socially distanced than buying a boat and hitting the water?

What Makes a Region: A look at three definitions of the Great Lakes

Beyond the obvious proximity to the five Great Lakes, what makes a region? The Midwest has its own stereotypes – the Rust Belt has become a popular term for northern post-industrial cities – but perhaps the draw of the Earth’s bounty of freshwater is more meaningful?

Aside from the cultural influence of the lakes, the Great Lakes region is a combination of environmental science, politics and economy.
