#WaukeganRiver and its ravines to be subjects of study; ‘This is for the next generation and the generations to follow’

An engineering design study starting by Sept. 1 will determine what can be done with the Waukegan River system to enhance the area as it flows into #LakeMichigan.

By Steve Sadin | Lake County News-Sun
UPDATED: August 11, 2025

Excerpt: "Labeled the Waukegan River Ravines Corridor Improvements Project, the effort will design strategies to stabilize eroding ravines, remove invasive species, enhance native habitat and improve recreational trails. Some trails already exist in parks that abut the ravines.

"#Waukegan Mayor Sam Cunningham, who chaired the Mayor’s Water Equity Commission of the Great Lakes and St. Lawrence Cities Initiative during his first term, reengaged with the organization when he returned to office in May. Building partnerships is important for the city, he said.

" 'Rebuilding Waukegan requires partnerships,' Cunningham said. “With me being involved again, and this in the pipeline, will only further our goal of rebuilding Waukegan. We are working with partners who can help our vision.”

"Funded by a $250,000 grant from the National Fish and Wildlife Foundation to Waukegan via the Great Lakes and St. Lawrence Cities Initiative, Altenberg said it will enhance the effort to adapt to climate change, flooding and erosion in the area.

"Daron Terfehn, a special project analyst for the city of Waukegan, said the Waukegan River is a watershed stream that brings rainwater from the ravines around the city into Lake Michigan near the harbor. The area incurred a lot of erosion in the past.

" 'A lot of things have been dumped in the ravines over the years,' Terfehn said.

" 'Everything (there) flows into Lake Michigan. It affects the salmon, the trout, everything that’s in the lake.'

"Before projects can be discussed with potential partners like the Waukegan Park District and the Lake County Stormwater Management Commission, Terfehn said the results of the study are essential. He estimates it will take approximately a year.,

" 'Much of the land is private property,' Terfehn said. 'Some belongs to the city and some to the Park District where it touches their parks. Once we have an idea of what we have to do, we can work with the Park District and stormwater management to do projects together.'

"When Cunningham began his second term, Altenberg said the mayor quickly took a leadership role again with the Great Lakes Initiative organization. He is now the co-chair of the Western United States Region which includes Illinois, #Michigan, #Wisconsin, #Minnesota and #Indiana."

This may be my first Canadian #clay sample, but it’s my second sample from the #GreatLakes region. A while back, a friend brought me some clay from Lake Ontario (left) which melts into a pea-green glaze. The clay that I collected from the Niagara Peninsula—about 80km/50mi inland from the shores of Lake Ontario—gave very similar results.

I’ve also collected clays five miles apart (or even in the same general location but different elevations) that were vastly different from each other. #WildClay

Scientists discover new life aboard Great Lakes research vessel | UMD News CenterScientists discover new life aboard Great Lakes research vesselWhen Large Lakes Observatory (LLO) Marine Superintendent Doug Ricketts brought a cup of tar-like substance to researchers last September and asked, "Think you guys could do anything with this?" he probably wasn't expecting to launch the discovery of a brand-new species. But that's exactly what happened when UMD scientists examined the mysterious "ship goo" seen oozing from the R/V Blue Heron's rudder shaft during an unanticipated repair.The research vessel, which had been pulled out of Lake Erie into the Great Lakes Shipyard, Cleveland, to fix a noisy propeller shaft, yielded an unexpected treasure: previously unknown microorganisms thriving in the warm, oxygen-free environment of the rudder shaft housing. Lead researcher Cody Sheik, a biologist at UMD and LLO, and his team temporarily dubbed their discovery "ShipGoo001".Unexpected Life Form"The biggest surprise was that the ship goo had life in it at all," Sheik explained. "We thought we'd find nothing. But surprisingly, we found DNA and it wasn’t too destroyed, nor was the biomass too low."Instead, through DNA sequencing and comparison with global databases, the team confirmed they had discovered entirely new species. The microbes appear to thrive in the peculiar conditions found in the rudder shaft: a semi-warm, stable environment with no oxygen, where the grease creates a unique ecological niche.The discovery highlights how much remains unknown, even in familiar places. While the Sheik Lab has extensively studied microbes living in extreme environments like Lake Superior, deep ocean hydrothermal vents, and hot springs, the built environments we interact with daily–from ships to buildings–remain drastically undersampled.Home of DiscoveryThe R/V Blue Heron is part of the US Academic Research Fleet, a flotilla of ships owned by the United States government to conduct research in oceans and coastal waters. The Large Lakes Observatory at the University of Minnesota Duluth operates the R/V Blue Heron, which is the only academic research vessel designated for the study of the US Great Lakes. While many of these research fleet vessels have helped discover new life in the oceans, this is the first time that new life has been discovered on a ship itself!The ‘ship goo’ organisms appear to be part of a complex food web, possibly even contributing to biocorrosion of the metal rudder shaft. Interestingly, while the particular species ShipGoo001 is new to science, some of its companions have been found in tar pits and petroleum wells around the world, suggesting these microbes may be more widespread than initially thought.The discovery raises intriguing questions, like where did these organisms originate? The lake waters surrounding the vessel are oxygenated, yet these microbes can only survive without oxygen. Sheik speculates they may have been dormant in the oil used to grease the rudder, waiting until conditions were right for growth. The fact that no oozing was observed during the vessel's previous maintenance in November 2021 adds another layer of mystery.Beyond satisfying scientific curiosity, the discovery could have practical applications. Some organisms in the “ship goo” appear to be methane producers, potentially useful for biofuel production. The next steps involve studying what these microbes actually do in their environment and understanding their metabolic processes.Take Time To Be Curious The warm, oxygen-free environment of the greased rudder shaft housing unexpectedly provides a home for previously unknown microorganisms. The find also underscores the importance of supporting basic science and allowing researchers the freedom to explore. "Scientists don’t often have time to be playful – we're focused and have projects to complete," Sheik said. "Time and resources for exploratory work can be daunting. But this shows why it matters."Following standard scientific protocol, the team will make the genome publicly available in repositories and publish their findings in peer-reviewed journals, allowing other scientists to build on their work.As for the official name, that remains to be determined. Sheik plans to collaborate with the community later this summer to help name the species."It's fun science," Sheik concluded. "By calling it ship goo for now, it brings some joy to our science. We can find novelty wherever we look."The discovery serves as a reminder that even in our everyday environments–or in this case, in the oily recesses of a research vessel–nature continues to surprise us. Sometimes the most remarkable discoveries come not from distant planets or exotic locations, but from the things we work with every day.

Manitoulin Island: The World's Largest Freshwater Island 🌊

Manitoulin Island is the world’s largest freshwater island located in Lake Huron The current name of the island is the English version, via French, of the Ottawa or Ojibwe name Manidoowaaling (ᒪᓂᑝᐙᓕᓐᒃ). It's home to hiking trails, Indigenous communities, and serene beaches. You can even find lakes *on* the island—with islands in them!

While fish can swim to cooler or warmer waters to tolerate gradual temperature changes, the same isn't always true for sudden jumps in either direction, Abdelhady said. Fish eggs are particularly susceptible to abnormal temperature spikes or drops.

Hot and cold streaks can also disrupt the natural mixing and stratifying cycles of the lakes, which affects the health and water quality of lakes that people rely on for recreation and drinking water

1. My primary care doc put in a referral for the orthopedic hand doc. Hopefully the referral will get me a quicker appointment than my phone call did (late September).
1.a. Blessed I didn’t need the orthopedic hand doc in over 4 years. Trouble is, if it’s been over 3 years, you’re treated as a new patient so there’s a long wait for an appointment at a time when you really need to get in sooner than later. Lesson learned.
2. High of 75 here in the Blue Ridge Mountains today and only 72 tomorrow. Yay!
3. Listened to my favorite songs in the car on the way to and from the doctor appointment. Windows down, sun roof open and good music is good for the soul.

Bonus - love looking back at my nightly sunset shots on Lake Superior when we stayed at our family cabin last year. I miss living near the Great Lakes (home).

#RadioactiveWaste leakage would be threat to area: critic

By Doug Diaczuk The Chronicle-Journal Apr 22, 2025

"A radioactive waste specialist from the United States says #NuclearWaste disposal sites place a giant bullseye on an area, as well as all communities along the transportation route, and residents of Northern #Ontario should take notice.

"#KevinKamps, a radioactive waste specialist with #BeyondNuclear, a non-profit advocacy group in the United States, will be speaking in Thunder Bay at Environment North's annual meeting on Wednesday [April 23].

"Kamps has opposed several nuclear waste sites across North America, including a site in the #YuccaMountains in #Nevada and a site at #Kincardine in #Ontario at the #BruceNuclear Generating Station.

" 'That was a 20-year campaign all told, but we prevailed in the end,' Kamps said of the Kincardine site in an interview with The Chronicle-Journal.

"The Nuclear Waste Management Organization [#NWM] identified a site between #Ignace and #Wabigoon Lake as the location for a proposed deep geological repository [#DGR] for #SpentFuel from #Canadian #NuclearPower plants.

"Last summer, the #TownshipOfIgnace expressed a willingness to be the host community for the repository following a survey showing the majority of residents supported the site.

"But several #FirstNation communities have spoken out in opposition to the site, citing #environmental concerns and the safety of transporting spent fuel through the region.

"Kamps said if anything was to go wrong at the deep geological repository site it would be catastrophic: 'for all points #downstream, #downwind, up the #FoodChain, down the generations.'

" 'In your neck of the woods, what I find ironic is the current target in your area is just outside of the #GreatLakes basin and I think it is a raw political calculation to try to silence what has been more than a decade of U.S. congressional opposition to the #LakeHuronDump,' he said.

" 'Now magically a site has been chosen outside of the Great Lakes basin.'

"There are many safety concerns to take into consideration when it comes to nuclear waste, Kamps said, beginning with the transportation of nuclear material to the site itself.

" 'One of the most controversial aspects is the transportation component, because it makes it everyone's problem along those routes,' he said. 'So that is another part of our challenge, to educate communities that would be along the most likely transportation route, be it road, rail, or waterway.'

"Then there is the site itself, which Kamps said could be vulnerable to #ExtremeWeather, #NaturalDisasters, or even potential attacks.

" 'You had better know your geology really well because if and when this starts leaking from its containers into the geology, then it's a question of how long will it take to mix with underground waterflows and perhaps even surface waterflows,' he said. 'And then the risk flows with the water, and with the air.'

"For those opposed to such sites, Kamps said the best way to fight back is through the democratic process and engaging with government representatives at all levels.

"He cited the opposition to the #Kincardine site that was a 20-year fight and the role First Nations communities played.

" 'An important part of that was the #SaugeenOjibwayNation who asked good questions and in the end voted 86 per cent no to that dump coming into their community,' he said.

"In terms of what to do with nuclear waste from generating stations, Kamps said it should stay at the site of origin."

"In a recent incident, on June 21, a storm surge caused Lake Superior's waters to dramatically change, particularly near the beaches of Whitefish Bay and Sault Ste. Marie, according the Great Lakes Environment Research Laboratory.

Water levels in Whitefish Bay increased 45 inches in less than 2.5 hours, the largest increase recorded in the past 30 years."
