Krishnadev Calamur: A Fish With Cancer Raises Questions→

NPR

“Late last year, an angler caught a smallmouth bass in the Susquehanna River near Duncannon, Pa. That fish, officials from the Pennsylvania Fish & Boat Commission said this week, had a malignant tumor. It’s the first time this type of tumor has been found on a smallmouth bass in the river, the agency says.

Cancerous growths and tumors on fish are “very, very infrequent,” John Arway, the agency’s executive director, said in an interview.

”These cancers can be initiated by contaminants,” he said.”

In addition to this story, more Information on the fish populations in the Susquehanna River is available here.

Steven Elbow: Lake Conservation Can't Keep Up with Pollution Increases→

Cap Times:

“A new report says that a 14-year effort to clean up Lake Mendota couldn’t keep up with increasing amounts of phosphorous streaming from the watershed.

The study from the Water Sustainability and Climate Project at the University of Wisconsin-Madison says a 14-year effort to clean up Lake Mendota failed because of changes in farming, land development and climate change.

“There’s been a lot of tremendous work and effort to at least stay on the treadmill,” said co-author Eric Booth, a Climate Project researcher. “The problem is the treadmill keeps getting faster and faster with these other unaccounted for drivers of change.”

The result is that increasing efforts have slowed but not improved the decline of the lakes.

The report is specific to Lake Mendota, but could have implications worldwide as communities elsewhere try to tackle similar problems.”

Andrew McCann: Atlanta's Beltline Project

Urban Milwaukee:

“One of largest-scale urban redevelopment programs ever undertaken in the United States is the Atlanta BeltLine, a sustainable redevelopment project in Atlanta, GA. The project is converting 22 miles of disused Civil War-era railroad tracks encircling the city into a new transit greenway – a walkable green space – that links over 40 neighborhoods across the city like never before. The project is still in its early stages, but has already stimulated dramatic changes in people’s understanding of where they live and how they interact with their space. With plans underway to incorporate the city’s existing subway system, its new streetcar, and a system of multi-use trails across the city, the BeltLine is fast becoming one of Atlanta’s defining features.
The project’s origin is just as remarkable. The BeltLine began as a “kernel of an idea,” the subject of a Georgia Tech graduate student’s 1999 Master’s thesis on architecture and urban planning. Now an urban designer at Perkins+Will, Ryan Gravel’s original vision for the BeltLine has expanded beyond what anybody imagined in the project’s early days.

“Today the vision…include[s] ideas like 1,400 acres of new parks, a linear arboretum, public art, new streetscapes, brownfield remediation, significant investments in affordable housing, and a list that continues to grow,” says Gravel.

The BeltLine made its public debut in 2001 and began its implementation in 2005. Though still in the early stages of development – worst-case projections are for a 2031 completion date – it’s already had an enormous impact on the city.

“It is not only changing the physical form of the city, it’s changing the way we think about this place we live in and the decisions we make about living here,” says Gravel.”

NASA: US Government Develops Tool to Detect Toxic Algal Blooms

Accuweather:

“Four government organizations are combining resources to tackle a threat to U.S. freshwater: toxic algal blooms. These harmful algal blooms cost the U.S. $64 million annually to combat.

NASA is working alongside the National Oceanic and Atmospheric Administration, the Environmental Protection Agency (EPA) and the U.S. Geological Survey (USGS) to transform satellite data used to monitor ocean biology into valuable information to monitor detrimental freshwater algal blooms.

The new project, using ocean color satellite data, will formulate an “early warning indicator” for toxic algal blooms in freshwater systems and aid public health advisories, NASA reported.
”Observations from space-based instruments are an ideal way to tackle this type of public health hazard because of their global coverage and ability to provide detailed information on material in the water, including algal blooms” said Paula Bontempi of the Earth Science Division at NASA Headquarters in Washington, D.C..”

Elizabeth Dunbar: Polluted Minnesota Lakes and Rivers→

Minnesota Public Radio:

“Six and a half years after Minnesotans voted to raise taxes to clean up lakes and streams, it’s clear the state has a long way to go. A report released Wednesday representing data from half of the state’s watersheds shows half or more of lakes and streams monitored in the southern half of the state are plagued by bacteria, sediment, nutrients and other pollutants.

Those bodies of water are often too nasty to swim in and can’t fully support fish and other aquatic life, according to the report. With help from the Legacy Amendment, which voters approved in 2008 to raise sales tax revenue for the environment and the arts, the Minnesota Pollution Control Agency is monitoring and assessing lakes and rivers in all of the state’s 81 watersheds — geographic areas defined by all of the waters emptying into the same body of water.”

Ron Meador: Can Minnesota Achieve Sustainable Water Use?→

MinnPost:

“Swackhamer has a serious gift for synthesizing complex scientific material in ways that non-specialist listeners can grasp, and it’s paired with matchless expertise on this subject: She directed the University of Minnesota’s Water Resources Center from 2002 to 2014, and led the effort to produce the massive Minnesota Water Sustainability Framework, commissioned with funds from the Legacy Amendment to provide policy guidance for decision-making over the next 25 years.

She has served in leadership roles on scientific panels advising the U.S. Environmental Protection Agency and the International Joint Commission, and has just begun a three-year term on a National Academy of Sciences panel focused on environmental science and toxicology, recognition of her focus on toxic-chemical pollution. And she does not shrink from controversy. For example, she had much to say about the fraught connections between large-scale agriculture and Minnesota’s water problems, some of it quite provocative.

If we shift from issues of water quantity to issues of water quality, she observed, we see that more than 4,100 lakes and stream sections across the state – or more than 40 percent of the total – are classed as “impaired” because they fail to meet federal quality standards. The major driver of these impairments is excessive inputs of nutrients, primarily phosphorus and nitrates from fertilizers, and the major source of those nutrients is row-crop agriculture.”

Anson Mackay: Lake Baikal Threatened by Proposed Dam→

The Conversation:

“Mongolia is hoping a massive dam on its largest river could provide much needed power and water for the country’s booming mining industry. However environmental groups are concerned that the hydroelectric power plant and a related pipeline project will do immeasurable environmental damage to oldest and deepest freshwater body in the world: Lake Baikal...

he Shuren Hydropower Plant, planned on the Selenga River in northern Mongolia, was first proposed in 2013 and is currently the subject of a World Bank-funded environmental and social impact assessment. In tandem, Mongolia is also considering building one of the world’s largest pipelines to transport water from the Orkhon River, one of the Selenga’s tributaries, to supply the miners in the Gobi desert 1,000km away.

By far the largest and most important of the 350-plus rivers that flow into Lake Baikal is the Selenga River, which contributes almost 50% of the lake’s water. The Selenga and its tributaries cover a vast area, much of it in northern Mongolia, and the catchment of Lake Baikal is bigger than Spain. The river enters Lake Baikal through the Selenga Delta, a wetland of internationally recognised importance.

The delta is crucial to the health of Lake Baikal. Its shallow waters are a key spawning ground for Baikal’s many endemic fish and is on the migratory route for millions of birds every year. It also filters out impurities flowing through the river before they reach the lake.”

Tim Crosby: Researchers Tracking Mudpuppies→

Southern Illinois University:

“Alicia Beattie, a graduate student zoology at Southern Illinois University Carbondale, holds a mudpuppy caught in a frozen lake in northern Illinois this past winter. The full aquatic salamanders are the subject of an ongoing research project funded the Shedd Aquarium in Chicago to learn more about the threatened species, which lives in freshwater lakes and streams throughout the eastern half the country.

“One of the angles of this project is to find out more about how they live in lakes,” said Matt Whiles, professor of zoology and interim director of the Cooperative Wildlife Research Laboratory, and director of the Center for Ecology at SIU. “There’s been a fair amount of research on populations that live in streams and rivers. We’re looking at populations that live in lakes in the Great Lakes area. Much less is known about those. The species does appear to be declining, but at one time it was fairly abundant throughout their range. Nobody really knows why.”
Whiles, along with Robin Warne, assistant professor of zoology, is supervising the work of SIU zoology graduate student Alicia Beattie, who is spending many hours drilling holes on frozen Wolf Lake in northern Illinois and trapping, studying and releasing the foot-long “fish with legs.” Beattie, the daughter of Jean and Joe Beattie of Hastings, Minnesota, said her favorite aspect of the research so far has been meeting and working with people from different walks of life and organizations. She also has enjoyed the many and varied challenges associated with trapping and studying mudpuppies.”

Dennis Anderson: Some Farmers for Buffer Bill→

Star Tribune:

““What happens to water as it goes through my farm is my responsibility,” Kanne said, noting that in his part of the state, the amount of drain tile laid by farmers has doubled every two years for the past 10 years, significantly altering the region’s hydrology.

“We need to get [buffer requirements] in place because, as a farmer, I’m not the problem,’’ Kanne said. “But I’m part of the problem. And I will be part of the solution.’’

Not so fast, say lobbyists who have plied the Capitol’s hallways in St. Paul this session representing Minnesota farm and commodity groups. Their objective since Gov. Mark Dayton announced his buffer initiative in January has been to weaken, stall and/or kill the proposal. Keep the dirty water flowing, they seem to say.”

Darrel Mosel: Farmers will Find Production Benefits with Buffers→

SC Times:

“As a farmer who has a drainage ditch, a small creek and larger creek flowing through my land, I know that when there isn’t a buffer between the crop field and the streambank, runoff takes soil and any chemicals along for the ride right over the edge. I have buffers that range from 50 to 120 feet wide. That leaves me plenty of room to raise crops on the rest of my land. And it makes a difference — the stream banks are stable, and I know my soil and inputs are staying where they belong.

But upstream and downstream, people are still trying to farm to the edge, and when heavy rains come, it’s a disaster. Creeks turn chocolate, and the banks cave in. This type of farm run-off is a major contributor to our state’s water pollution problems. It’s also an incredible waste of seed, fertilizer and chemicals.”

The intended benefits of shoreline buffers that is well described by a practicing farmer.

Charles Marohn: Environmentalism and Density on Minnesota's Lakes→

Strong Towns:

“A small town in Minnesota just gave an extended middle finger to one of the state’s most impotent bureaucracies. What is setting up is a school yard brawl between two underweight, skinny greasers with switchblades. Could be a lot of slapping and name calling, but if things go horribly wrong there is the potential that someone gets their throat slit.

Detroit Lakes is a town very similar to my hometown of Brainerd, with the primary distinction being that their auto-based, Ponzi-scheme development blowout happened within the city limits where here in Brainerd that mess was absorbed in the neighboring (competing) city of Baxter. In a grass is greener kind of way, I’ve always perceived them to be doing a little better than we are here. I’m probably wrong.

The current dispute between Detroit Lakes and the Minnesota Department of Natural Resources (DNR) is over an $11.8 million hotel and restaurant very near Detroit Lake.”

Charles Marohn is right to be infuriated with Minnesota's shoreland density requirements for cities -- all Minnesota citizens should be disappointed. The State's shoreland development standards are old. These standards are outdated with regard to lake protection, and they're inconsistent with good land use development principles and practices. When the Minnesota DNR attempted to revise the 1970-80s era standards several years ago, Governor Pawlenty dismissed them because, perhaps rightly, the public and local governments might not have accepted the shoreline buffer provisions that were proposed to protect water quality. Those proposed standards would have also allowed cities to use their own density standards provided that the area was served by sewer and proper stormwater controls. In Lakeshore Living, we speak to the changes that are necessary and how we could use sound place-making principles and good bottom-up community design. Charles Marohn helped me, a lake ecologist, better understand Strong Town principles. Thanks Charles! 

Mitch Smith: Conflict between Farm and City Water→

New York Times:

“The flat, endless acres of black dirt here in northern Iowa will soon be filled with corn and soybean seeds. But as farmers tuned up their tractors and waited for the perfect moment to plant, another topic weighed on their minds: a lawsuit filed in federal court by the state’s largest water utility.

After years of mounting frustration, the utility, Des Moines Water Works, sued the leaders of three rural Iowa counties last month. Too little has been done, the lawsuit says, to prevent nitrates from flowing out of farm fields into the Raccoon River and, eventually, into the drinking water supply for roughly 500,000 Iowans. The suit seeks to make farmers comply with federal clean-water standards for nitrates that apply to factories and commercial users, and requests unspecified damages.”

No price signals to farmers for their export of pollution downstream, so other legal means are being explored to address degraded water quality,

James Fallows: Nice Downtowns→

The Atlantic:

“It’s tempting, if you haven’t seen the varied stages of this process, to imagine that some cities just “naturally” have attractive and successful downtowns, and others just don’t happen to. It’s like happening to be located on a river, or not.

But in every city we’ve visited with a good downtown, we’ve heard accounts of the long, deliberate process that led to today’s result. The standard discussion will go: “See this restaurant [bar / theater / condo / Apple store with surrounding retail outlets]? Ten years ago, you wouldn’t have [dreamed of coming here at night / seen anyone but crack addicts / been able to rent a condo, or wanted to].” We’ve heard variations of this account so often we now feel a little let down if we don’t get the “this used to be a crack house” speech when visiting a nice hotel or downtown tech-company headquarters...

In every place we’ve been, every one we’ve talked with about downtown recovery stresses the crucial importance of getting people to live there.”

How do you get people to live there? It often requires investing or restoring amenities.

Scott K. Johnson: Lake Science Using Remote Sensors→

Ars Technica:

Rensselaer Polytechnic Institute

“The largest streams that flow into Lake George are now being monitored year-round by sampling stations. Water is pulled into a heated enclosure (ice isn’t helpful) where it is analyzed by a data-logging device with probes for things like temperature, pH, dissolved oxygen, conductivity, dissolved organic matter, and algae content. Other instruments measure the water level and flow velocity of the stream. The data is periodically uploaded over a cellular Internet connection and entered into the project database. And at the same time, a carousel of sample bottles is automatically filled and periodically retrieved for additional tests in the analytical chemistry labs back at the field station.

That same kind of data-logger is also going to be active out in the lake itself, operating from a set of anchored, floating platforms. The floats raise and lower the data-loggers, allowing them to sample a vertical profile of the lake. That’s enormously useful, because the lake stratifies into a warmer surface layer and a cooler deep portion (as most lakes do). The first two floats hit the lake last summer, but five will go out this spring after the ice melts.

A number of current profilers will be placed at the bottom of the lake as well. These devices bounce acoustic waves off particles drifting by, using the slight Doppler shift of the returning waves to calculate velocities at various heights above the device. For now, they will simply store data to be downloaded when they are retrieved, but they may run cables in the future to allow near real-time access.”

Very cool. Data and models will provide useful information for lake management. 

David Goldenberg: How Fishing Pros Finally Caught George Perry’s Miracle Bass→

FiveThirtyEight:

“In late 2009, two men walked into a room somewhere in Japan and found a fisherman hooked up to a polygraph. His name was Manabu Kurita, and he was there to answer some questions. The 32-year-old fishing guide had claimed to have caught a bass that weighed just under 22 pounds, 5 ounces — a weight that would make it co-world-record holder in the all-tackle weight category for largemouth bass, the most hallowed class in all of fishing. The other men in the room were representatives from the International Game Fish Association (IGFA) and, with the polygraph running, they asked Kurita about the precise position of his boat on Japan’s Lake Biwa and the tackle he used to haul in his catch. His answers from the hourlong session evidently passed muster; six months after he hauled the fish in, the catch was certified as the IGFA’s co-world-record holder.”

Interesting story on the history of big bass. To clarify, at the moment there are two recognized subspecies of the largemouth bass (Micropterus salmodies): the northern largemouth (Micropterus salmoides salmoides) and the Florida largemouth (Micropterus salmoides floridanus). 

Kyle Potter: Dayton Proposes More Money to Reimburse Farmers for Buffers →

Associated Press:

“In an effort to ease concerns about his plan to create 50-foot buffer zones along Minnesota waterways, Gov. Mark Dayton started lining up more money this week to reimburse farmers.

The governor set aside $20 million in his proposed bonding bill unveiled Tuesday to buy up swaths of cropland from farmers. The state had also previously applied for hundreds of millions of dollars through a federal program that pays farmers in 10- to 15-year contracts for environmentally friendly practices that could include buffers, his office said.”

The current paradigm is that we have to pay farmers to do the right thing. Why as a farmer can I pollute my neighbor's place or a public resource? Why does my neighbor have to pay me to stop me from sending my pollution downstream to him? Is it my right to pollute? What would Aldo say?

Josephine Marcotty: Buffer are a Rallying Cry for Cleaner Water→

Star Tribune:

“Buffers are a remarkably simple solution for a lot of pollution. “Mother Nature has an awesome filter,” said Richard Schultz, a professor at Iowa State University who has studied the effects of buffer strips on one stream near Ames, Iowa, for two decades. “Let her do her thing, and she will do it.”

Buffer strips have been a common feature in farming for centuries. Barriers of grass, bushes and trees can block the rush of water from increasingly large rainstorms, slowing erosion on the land and in river beds. More important, they also stop most of the soil, phosphorus and nitrogen that the water carries off. Tall, stiff, prairie grasses on the edge of a field act as a wall to hold soil. And phosphorus, a nutrient that produces massive and sometimes toxic algae blooms in water, sticks to the soil and stops at the barrier. Plants also capture nitrogen through their roots, absorbing it and releasing it into the air before it reaches the stream.”

Yeah but, a uniform regulation consisting of 50 feet of perennial vegetation is a great start -- compared to many places without a buffer.

Scott K. Johnson: WI Cutting and Censoring Science→

Ars Technica:

“Since taking office in 2010, Wisconsin Governor Scott Walker has reshaped the state’s Department of Natural Resources (DNR). He appointed a former state senator and critic of the agency to be its secretary and hired an outside “deer czar” in response to hunters’ complaints about the state’s management of the deer herd. Gov. Walker also re-wrote state mining regulations to clear the way for an ill-fated iron mine proposal that was finally abandoned last month. Several days ago, the Milwaukee Journal Sentinel reported that the mining company’s lobbyist and spokesman had been considered for appointment as the DNR’s deputy secretary—until officials realized there was a federal law specifically preventing that kind of thing. (He was, instead, hired for a job in another agency.)

Now, the DNR has come under the budget knife. Among other changes and position cuts, the agency’s science bureau faces a 30 percent reduction in staff. Now, Wisconsin Watch reports that the DNR is considering eliminating the science bureau altogether, shuffling remaining staff into other divisions.”

I don't like to post on politics, but it is sad to see natural resource management agencies, like the WI DNR, discounted and their valuable work reduced.

Julie Buntjer: Minnesota Governor Dayton Talks about Buffer Initiative→

Governor Dayton at Worthington

“An estimated 200 people, including farmers from more than a 12-county area of southern and western Minnesota, packed inside the Worthington Fire Hall Thursday morning to ask questions and voice concerns about Gov. Mark Dayton’s proposal seeking to require 50-foot buffer strips along all lakes, rivers and streams across the state.

Arriving a few minutes behind schedule to a standing-room-only audience, Dayton acknowledged immediately that there will be disagreements and everyone is entitled to an opinion. He listened to question after question and occasionally offered responses on his bipartisan bill (HF1534/SF1537) for nearly two hours.

Dayton’s proposal seeks to create an additional 125,000 acres of water quality buffer strips statewide, and he wants to see the initiative under way before his term expires in another three and a half years.

The idea for added buffers came from the governor’s first-ever Minnesota Pheasant Summit late last year. Since then, it has evolved to focus not only on additional habitat and space for pollinators, but also on improving water quality.”

Adam Nagourney, Jack Healy and Nelson D. Schwartz: California Drought Tests History of Endless Growth→

New York Times:

“For more than a century, California has been the state where people flocked for a better life — 164,000 square miles of mountains, farmland and coastline, shimmering with ambition and dreams, money and beauty. It was the cutting-edge symbol of possibility: Hollywood, Silicon Valley, aerospace, agriculture and vineyards.

But now a punishing drought — and the unprecedented measures the state announced last week to compel people to reduce water consumption — is forcing a reconsideration of whether the aspiration of untrammeled growth that has for so long been this state’s driving engine has run against the limits of nature.”

Great pictures and a story that asks difficult questions challenging our paradigm of technical solutions to limits of nature.
