Changes proposed to ballast water rules


From the Wisconsin Department of Natural Resources (WDNR):

Published: December 21, 2010 by the WDNR Central Office

MADISON – Wisconsin is proposing to change its requirements for oceangoing ships arriving in its Great Lakes waters. The change would set ballast water discharge standards to those required by the International Maritime Organization. The proposed change reflects the latest science about reducing the risk from invasive species carried in the ships’ ballast water, state officials say.

The proposed modifications to a general permit issued by the Wisconsin Department of Natural Resources to large oceangoing commercial ships will be the subject of a public hearing January 26 in Superior.

New Funds Allocated to Halt Asian Carp

Many efforts are still being made to stop, or reduce the number of, Asian carp spreading to the Great Lakes. Yesterday $47 million in funds were announced that will go toward 13 different projects of prevention.

In addition to creating a lab in Wisconsin where Asian carp DNA will be sampled, pathways into the Great Lakes are going to be examined with hopes of finding ways to block the route of the fish.

Some of this funding is coming from money that was previously designated by the federal government for clean-up and restoration of the Great Lakes. Arguments have been made that the funding to fight Asian Carp should come from a separate source. For further information, see the Detroit Free Press article.

Phosphorus Rules in Effect in Wisconsin

Passed in June this year by the Natural Resources Board, the Phosphorus Rules will go into effect this month. Compliance with these rules, basically governing the numeric level of phosphorus that can be permitted to enter the water, will help to keep waters cleaner and will ultimately benefit fish and wildlife, fisheries, waterfront property owners, and recreational water users among others. Some of the negative effects of phosphorus include "toxic algae, excessive weed growth and murky water" (WDNR release).

The rules were developed over a period of time based on years of scientific research and evidence. Input from farmers, water treatment systems, manufacturers, food processors, local governments and environmental groups was also essential in their formation. There is also further work being done to help lower the cost of compliance.

For more information, see the WDNR news release.

Another Step in Fox River Cleanup & Restoration

An agreement was reached between the City of Green Bay, Brown County and the Army Corps of Engineers that a sum of $5.2 million go toward cleanup and restoration of the Fox River. Most of this money will be spent on dredging polychlorinated biphenyl (PCB) contaminants from the river. Part of this money will also be set aside for future response costs. Officials say this payment shares "reflect the roles of the Corps, the County and the City in the resulting damages to natural resources."(WDNR release) This is one in a series of agreements relating to contamination in the Fox River and Lower Green Bay.

For further information, see the WDNR news release, or their information page about the Fox River/Green Bay Cleanup Project.

Road Sealant Responsible for Water Contamination

Water samples have been taken from Alaska to Florida by the USGS and results are in. Contaminated lakes and rivers show a higher concentration of polycyclic aromatic hydrocarbons (PAHs), on the rise since the 1960s. These contaminants are toxic for fish and other aquatic life.

Researchers have found the main source of the PAHs to be coal-tar-based pavement sealant. One of the most common uses for this material is the squiggly, shiny black lines that seal the cracks in roadways. While effective, this material has a life span of only three to five years and is easily being transmitted into lakes and stream ecosystems. Storm runoff is a common mode of travel for PAHs from the sealant into the lakes.

The USGS news release gives further details, and the full journal article is available in Science of the Total Environment. For further reading suggestions, see our recommended reading list on Understanding and Protecting Groundwater.

Clean Marina Update

With the addition of five new marinas yesterday, a total of nine have joined the Clean Marina Program in the last five months. This program, initiated by a collaboration between the Wisconsin Sea Grant and the Wisconsin Marina Association, is meant to help marinas within the state take steps to better protect their natural resources. Voluntarily taking these steps, the marinas also become safer and environmentally friendlier places for all parties involved.

Yesterday's five new additions included The Abbey Marina (Fontana), Gaslight Pointe Marina (Racine), Lakeshore Towers (Racine), Manitowoc Marina and SkipperBud’s Reefpoint Marina (Racine). Beside the nine marinas that have already become certified, there are also several marinas that have pledged "to keep Wisconsin's waterways free of harmful chemicals, excess nutrients, and debris and commit to actively pursue designation as a Wisconsin Clean Marina" (Clean Marina website).

For more details on yesterday's event, see the UW Sea Grant press release.

New Rules Regarding Groundwater Virus Treatment

Later this year, rules will go into effect that require disinfection of water by all municipal water systems in Wisconsin. This will increase protection for any state residents whose drinking water comes from groundwater. These rules are based on a discovery highlighted in the 2010 Groundwater Coordinating Council Report that showed viruses are able to travel through layers of rock and soil, which was previously thought to be an adequate filtration system. The Groundwater Coordinating Council (GCC) is responsible for identifying areas where research is needed, reviewing research proposals, and publicizing research findings.

In addition to assessing water quality, the 2010 GCC Report also "described recent research on arsenic treatment, the effects of nitrates on stream invertebrates, the occurrence of mercury in wetlands, extreme precipitation events and developing new tools for investigating fecal contamination" (WDNR Release).

Wisconsin's Water Library offers reading lists for the following related topics: Arsenic in Groundwater, Drinking Water Quality, Protecting our Wetlands, Understanding & Protecting Groundwater and Wastewater Treatment.

Great Lakes Earth Partnership

Earth Partnership for Schools (EPS), a statewide initiative, is growing. Founded in 1991, the program is meant to connect people with the land and water where they live. One of the program's goals is to allow children to experience nature while at school. Ecological restoration is another main focus. EPS helps young ones to understand their connection to the land and how they can help to give back.

Phase I of the Great Lakes Earth Partnership, a new regional EPS initiative funded by Wisconsin Sea Grant, recently took place in waters across the state including the Milwaukee River, estuaries of Lake Superior, the Kakagon Wild Rice Sloughs and others. Findings of the different teams will be discussed in Green Bay this winter. Read more about phase I in the Arboretum News Release.

Phase II is scheduled to continue in 2011 with funding from the EPA Great Lakes Restoration Initiative.

Grant to Document and Survey Five Shipwrecks

The Wisconsin Historical Society (WHS) recently received a $170,000 grant from the Federal Highway Administration Transportation Enhancement program that will fund the documenting and surveying of five shipwrecks in Lake Michigan. Divers will measure, photograph, and sketch the vessels to create a digital mosaic to show landlubbers how the wrecks appear underwater.

The five wrecks that have been selected include the S.S. Milwaukee (near Whitefish Bay), the EMBA (near Milwaukee's main harbor), the Floretta (near Manitowoc), the America (near Kewaunee), and the Lakeland (near Sturgeon Bay). These ships sank between 1880 and 1932 and were selected for this project because "they represent a cross section of historically significant vessels" (JSonline release).

For more information about Wisconsin's Great Lakes Shipwrecks, visit the UW Sea Grant and Wisconsin Historical Society site, wisconsinshipwrecks.org. The Wisconsin's Maritime Trails site was also created based on the Maritime Trails program founded by WHS. The Water Library also has a reading list of books about Great Lakes Shipwrecks.

35th Anniversary of Sinking of Edmund Fitzgerald

For Release: November 9, 2010

Contact:
Moira Harrington, communications manager, (608) 263-5371, moira@aqua.wisc.edu
Chin Wu, University of Wisconsin-Madison engineering professor, (608) 263-3078, chinwu@engr.wisc.edu

Madison (11/9/2010) -- The intense and dangerous wind storm and accompanying high waves the Great Lakes states experienced in late October is thought to be the same kind of storm that occurred on Lake Superior causing the fatal wreck of the ship Edmund Fitzgerald 35 years ago on Wednesday. A University of Wisconsin Sea Grant Institute-funded researcher is studying extreme waves in hopes of preventing future tragedies.

Extratropical cyclones are characterized by very strong winds carried over a long distance generating large waves. Buoys on the northern part of Lake Superior recorded waves as high as 27 feet in the recent storm. But the lake might have been even rougher during the Edmund Fitzgerald storm on Nov. 10, 1975, according to a scientific process called hindcasting, the opposite of forecasting.

Using a combination of observational data and computer modeling, scientists at NOAA’s National Weather Service and the Great Lakes Environmental Research Laboratory in Michigan show that sustained winds were likely blowing at 50 to 60 knots, roughly 57 to 69 miles per hour. Winds of that velocity would have generated waves about 24.6 feet high.

Such rough conditions could have produced an individual wave 46 feet high, although “rare and unlikely,” according to the NOAA scientists. No one will know exactly what caused the demise of the Edmund Fitzgerald because all 29 crew members perished. However, computer models showed that one such wave – known as a freak, rogue or giant wave – occurred at the exact time and location of the ship’s sinking.

Freak waves are exceptionally large, steep and asymmetric and often occur in the Great Lakes, according to University of Wisconsin-Madison researcher Chin-Hsien Wu. He is currently investigating the conditions and locations prone to producing the dangerous waves, which can take down a vessel like the Edmund Fitzgerald.

Freak waves can also be dangerous to kayakers and recreational boaters. Wu is particularly interested in the potential for rogue waves to occur in the Apostle Islands off the north shore of Lake Superior.

“The occurrence of extreme waves is still a mysterious phenomenon in the field of fluid mechanics,” said Wu, professor of civil and environmental engineering. The Apostle Islands include a complex network of islands and shoals that under the right wind conditions are likely to produce freak waves.

Using funds provided by the University of Wisconsin Sea Grant Institute, Wu is using a combination of wave gauge instrumentations and computer models to better understand the likelihood of extreme waves occurring at the Mawikwe Bay Sea Caves, a place that is popular, but also potentially dangerous, to sea kayakers who enjoy viewing the sea caves from the water. Since wave measurements are critical for safety, data must be transmitted in real-time via a website to alert paddlers to current wave conditions. The system was field tested in the summer and could be fully operational next year.

Improving knowledge of how extreme waves are created should prove invaluable to prevent further tragedies like the sinking of the Edmund Fitzgerald. Several commemorative activities are planned for tomorrow, including in River Rogue, Mich., near where the ship was built in 1958.

Consequences of Altering Stream Flow

A recent USGS study has shown several negative effects of altering natural stream flow. When the amount of water is changed, the types of creatures that are able to survive in the stream change as well. In many streams where the flow has slowed and the amount of water decreased, desirable species such as trout have moved on, making space for less desirable species such as carp. Trout require a quickly moving stream with a rocky bottom, whereas carp are more likely to be found in a setting with a much slower flow, more similar to a pond.

The surprising fact may be that 90% of the streams studied by the USGS had in some way been altered. Some of the causes for alteration may include "reservoirs, diversions, subsurface tile drains, groundwater withdrawals, wastewater inputs, and impervious surfaces, such as parking lots, sidewalks and roads." (USGS Release) Water quality and the health of the ecosystem are also being negatively affected by some of these changes to the streams. As water managers get a better understanding of the ecological effects of altering stream flow, they will be able to make more informed choices about dealing with streams in a healthy way. For further details and information, see the aforementioned USGS releases.

Bacteria DNA Discovered through Mud Core Study

Last summer, the public swimming area was closed for a month at Lake Wingra on account of cyanobacteria. These bacteria are not only smelly, but some can produce toxins that attack the liver or nervous system. Some researchers even say that these bacteria can be linked to liver cancer. One problem in studying this has been that few lakes have adequate historical records of cyanobacteria over time.

Cyanobacteria has not just been an issue in the recent past for Lake Wingra and other area Lakes. UW Madison researchers have now discovered that this bacteria is actually traceable back over 50 years. A modified kind of mud testing of the lake-bottom has shown Cyanobacteria DNA presence has risen over time as the climate has become warmer. This will be a way for many other lakes to be investigated as well.

See the full story released by UW News. For further reading on climate change, see our topical readings lists.

UW Water Resources Institute's New Videos

Within the past month, the UW Water Resources Institute has added two new videos. Produced by John Karl, these short YouTube videos are informative and to the point, a very effective way to spread some news from the field.

The first video(above), entitled "Testing Well Water for Microorganisms," explains a simple process of water testing to check for contaminants. The goal of the project is a methodology to find the source of the contamination.

In the second video, "A New Measure of Groundwater Flow," researchers experiment with pumping hot water into a well to determine the flow of the groundwater. The hot water will disperse more quickly if the water flow is quicker. Watch this video and others on University of Wisconsin Sea Grant Institute's YouTube channel.

Book Review: The Immortal Life of Henrietta Lacks

This book, containing many layers, could appeal to a wide array of readers, each for different reasons. The story focuses on the history of African-American Henrietta Lacks and her cells, while also detailing related progress in the field of science and medicine, the struggle of her family, and quest for knowledge which resulted in this book. Author Rebecca Skloot coherently connects the pieces of several stories to come up with this successful non-fiction piece which explores ethical issues in science and poverty.

The book jumps right in, reminding me of an action movie in which new ideas are constantly being brought to the table. Skloot keeps the reader’s attention, and is effectively able to interweave the strands of a story that she methodically gathered over several years. Comparisons she draws between the Lacks family's case and other pertinent health issues that have been brought to light over the years help the reader to become more informed about the medical field in general, giving this book much more of an appeal to the non-medical or non-scientist than previous books in the area may have had.

While I cannot say that I enjoyed this book, it was definitely more interesting than most of the non-fiction I encounter, and most people who I spoke with did recommend the book. Not only will it prompt your brain into action on several important issues, it will lead to thoughtful discussions with those who have read it.

Cat Islands Project Update

On Wednesday, Dean Haen, the manager of the Port of Green Bay, and other key people involved in the Cat Islands project met with members of the public to discuss the Cat Island Chain Restoration Project in lower Green Bay. The meeting was to discuss a possible time-line of events and clear up questions in the community. Funding for 35% of the project, estimated to cost around $34.2 million, has been secured by Brown County, but the rest of the funding, slated to come from the federal government, has no set time of arrival. In a Green Bay Press Gazette release, Haen is quoted: "We could be doing something as early as April, or as late as 2013."

For the majority of Wednesday's meeting, presentations were heard from representatives from the port, the Corps of Engineers, the Wisconsin DNR and the U.S. Fish & Wildlife Service. Members of the public brought up a few questions referred to in the article Timeline unclear on Cat Island restoration in Green Bay. A DNR fisheries biologist present at the meeting explained the benefits the project should have on aquatic life in Green Bay.

Water is Quite the Molecular Party

Within fractions of a second, any amount of water, containing two molecular structures, is able to break apart and reform, frequently. There is no issue with the recently discovered tightly packed, regularly arranged, crystal lattice molecular structure reforming with the jumbled, loosely packed, blob one. These complex and dynamic bonds allow for the forming of complex organic molecules. Water molecules easily form weak bonds with other neighboring molecules to create more complex compounds. This may be the reason why so many life forms come from a wet environment.

These are just some of the discoveries of a recent study, published in full-text by The Journal of Physical Chemistry B. Science Magazine also recently wrote a piece on the article called At the Smallest Scale, Water Is a Sloppy Liquid, which quotes UW Madison physical chemist James Skinner. This research has proven about water's molecular structure what other studies could only suggest.

Lake Michigan Water Trail - Wisconsin

Covering approximately 450 miles of shoreline in Wisconsin, and connecting to the Michigan and Illinois Water Trails, the Lake Michigan Water Trail aims to increase public lakefront landholding while providing information on access points, safety considerations, activities, and points of interest to recreationists. The Wisconsin DNR in collaboration with Wisconsin Coastal Management Program, National Park Service - Rivers, Trails & Conservation Assistance Program (RTCA), and Bay-Lake Regional Planning Commission aim to identify areas where public access is needed to close gaps in the trail, create an image for the Lake Michigan Water Trail Network that can be recognized by the public, and to provide "educational opportunities that will encourage the understanding of the Lake Michigan ecosystem" (DNR Release). The DNR plans to update their site as progress in made in the trail's construction and encourages interested parties to follow along.

EPA Promotes Lakeshore Stewardship

Scientists studying lakeshores have determined that poor lakeshore habitats have a direct relationship with a poor overall biological condition of the surrounded lake. The National Lakes Assessment (NLA) released a report earlier this year showing that while 56% of lakes are in good biological condition, nearly one third suffer from poor lakeshore habitats.

In light of these findings, EPA's Office of Water has launched a new Web clearinghouse called Lake Shoreland Protection Resources with information about protecting and restoring lake shorelands. It includes links to webcasts, fact sheets, videos and other resources. This is part of an outreach campaign to educate the public about NLA's findings.

More information for property owners is available through the Web clearinghouse or in the pdf "Shoreland Property: A Guide to Environmentally Sound Ownership." See our reading list for further reading on Coastal Community Planning & Development.

Study of the Upper Great Lakes: St. Clair River

In December of 2009, the International Upper Great Lakes Study released their summary report entitled Upper Great Lakes Water Levels: St. Clair River. This report conveyed findings from the first phase of a study of the upper Great Lakes, detailing the physical changes in the St. Clair River since 1962. Based on the findings of this study, the board recommends that no corrective action be taken in the St. Clair River at present, and that a comprehensive study be conducted to determine the need of future mitigative measures in the river due to the effects of climate change. The International Joint Commission (IJC), Canada and the United States, wrote a letter to US and Canadian government officials to inform them of the findings. The IJC also asked the committee to study what would happen to the great lakes system were the water levels in Lake Michigan and Lake Huron to be raise. The final report will be due in early 2012.

Hot topic: Flooding

2010 has already been another year of flooding for the state of Wisconsin. Many remember the severe floods of 2008 and in April 2009 a conference was held in Madison to consider what could be learned from this type of disaster and what can be done to mitigate the related problems. A new reports just out summarizes key contributions from that conference and covers a broad range of relevant topics about flooding in Wisconsin such as hydrology, climate change, water quality, health impacts, mitigation options, human services and economic consequences.

Experts who spoke at the symposium emphasized stronger leadership, more communication, better research, greater education and stiffer laws to help control food damage and reduce the loss of property and lives. They also identified a need to fundamentally reconsider how policymakers ask residents to share risk and responsibility, and the role of government in shaping those choices.

Danger in Rising Groundwater Usage Levels

Since the 1960's, the use of groundwater has more than doubled. Approximately 70-80% of groundwater is used for agricultural purposes. Most of this water ends up going into the oceans, which also impacts the rising sea levels. A large concern is the rate at which the groundwater is being used. Aquifers are being depleted much faster than they can be replenished.

A study was recently conducted by members of Utrecht University and the International Groundwater Resources Assessment Center at Deltares in the Netherlands. This research helped to identify areas where high groundwater depletion is occurring. Findings were published in Geophysical Research Letters, and a recap of some of the important points can be seen in the Discovery News article: Groundwater Levels Draining Fast. The article also provides some suggestions for how new irrigation techniques might be used to slow groundwater usage.

Mayor of Bayfield Wins Award, Going Traveling

Mayor Larry J. MacDonald of Bayfield Wisconsin was recently awarded the Peter Wege Award for best sustainable practices for a Great Lakes City under 100,000. Mayor MacDonald is a member of the UW Sea Grant Advisory Council.

In addition to the award, MacDonald will attend an invitation-only, all-expense-paid coastal economics workshop in Charleston, S.C., sponsored by the National Oceanic and Atmospheric Administration (NOAA), meant to help the NOAA Coastal Services Center identify what kind of information coastal managers need to make decisions later this month. And in October, the Embassy of Sweden has invited MacDonald, along with nine other U.S. mayors, to an all-expense-paid First European Green Capital Conference.

Congratulations, Mayor MacDonald!

29th Annual Banned Books Week

Banned Books Week has officially arrived. Kick-0ff events took place on September 25th and celebration will continue through October 2nd. Over 200 participants attended Chicago's kick-off event in the city’s historic Bughouse Square. Recognizing Banned Books Week is a way to celebrate the freedom to read. This began in 1982 because of a sudden increase in the number of challenged books. ALA defines a challenge as "an attempt to remove or restrict materials, based upon the objections of a person or group."

Ideas for and information about Banned Books Week can be seen here, and a listing of events by state is also available.

USGS Finds Elevated Nitrogen and Phosphorus in Groundwater

While nitrogen and phosphorus levels were previously an issue in groundwater systems, and many steps have been taken, and money spent to attempt to address this issue, a recently released study by the USGS shows that these levels have stayed the same or even risen since the 1990's. Some streams contain levels two to ten times higher than what is recommended by the EPA's Water Quality Standards. Areas affected most nationally include the Northeast, Midwest, and Northwest due to high use of fertilizer and manure for agricultural purposes.

Beside threatening aquaculture in these streams, drinking water with high nitrate levels is also a concern for humans. Aquifers and shallow wells are at risk and the potential for these nitrate levels to rise in the next few years as groundwater high in nutrient concentration penetrates the soil. Since private wells are not under the jurisdiction of the Federal Safe Drinking Water Act, homeowners should test their water annually to make sure that it is safe.

The USGS's fact sheet for Nutrients in the Nation’s Streams and Groundwater gives a detailed analysis of the study's findings. For further reading suggestions, see our recommended reading list on drinking water quality.

Genetically Engineered Fish and Chips

Would you side with 78% of surveyed adults who feel the FDA should not yet approve genetically engineered salmon for human consumption? Meetings have taken place, and parties are casting their votes. Some of the controversial topics are: whether or not the FDA should approve genetically engineered (GE) salmon, if approved, should labeling be required to advise consumers of the type of fish they are purchasing, and if the GE salmon are as healthy for people and for the environment as regular farm raised salmon are.

Obviously, there are many interdependent factors here, such as the methods companies use to grow the fish. AquaBounty Technologies, one of the sponsors of the GE salmon, submitted reports indicating the fish would be safe to eat, and safe for the environment. Many demand more research be done, and the public seems to be in agreement according to a study recently released by Food & Water Watch.

The FDA's Overview of Atlantic Salmon provides some useful information for interested parties. Food & Water Watch's release about the labeling of GE salmon can be seen here. For further reading, you can view our recommended reading list on aquaculture.

Project WET - Water Education for Teachers

Project WET, a national program that is delivered on a statewide basis, is available for teachers interested in becoming qualified to teach water education. They provide materials that can be used to get kids thinking about water and environmental issues. Materials from this non-profit water education program are available for kids ages 5-18. The prepared teaching materials are "designed to facilitate and promote awareness, appreciation, knowledge, and stewardship of water resources" (DNR release).

Incorporating different learning styles, including community service opportunities, there are over 90 activities available from Project WET. There are four main beliefs upon which Project WET was founded. One, water quantity and quality is important to all users. Two, knowledgeable water management is key to maintaining a healthy environment. Three, water connects a vast array of life and systems. Finally, being aware and respectful of water resources can encourage positive community involvement. Teachers are also able to sign up for workshops that are conducted by a network of Wisconsin facilitators.

For further curriculum ideas involving water, see our website.

Real-time wave information now available

by Gene Clark, PE (Wisconsin Sea Grant) and Dr. Chin Wu (UW Madison)

The sea caves at the Apostle Islands National Lakeshore are unique and spectacular natural rock formations. These eroded sandstone formations were formed when lake water and waves eroded the soft sandstone near the water edge, yielding a series of caves carved out of the exposed sandstone cliffs.

In Lake Superior, many sea caves are located on two of the islands—Devils Island and Sand Island—as well as on a relatively remote area on the mainland near Meyers Beach. The mainland sea caves can be viewed from above on land by a rugged two-mile hike along the bluff top trail from the Meyers Beach parking lot, but the best way to see these rock formations is on the water.

New Climate Change Resources in the Library

Recently, Wisconsin's Water Library updated our website to include information on, and access to a variety of climate change materials. We have created several climate change recommended reading lists for adults, which are broken down by category. These include Economies and Society, Policy, Great Lakes and Water.

We have also added a climate change recommended reading list for children, as well as a list of websites that were designed specifically for kids. For teachers and educators, we have added a curriculum ideas page which will provide some good starting points for those wishing to incorporate climate change into their lesson plans.

USGS Tracks Loon Migration by Satellite

Minnesota has the highest loon population in the continental US with over 10,000 adult loons. Many Midwestern loons reside in the Great Lakes during spring and summer months before they begin their annual migration to warmer areas such as the Pacific, Atlantic, or Gulf Coasts. Loons feed mainly on fish and other aquatic life.

Since the 1960's scientists have recorded cases of botulism in loons, but the numbers greatly increased starting in 1999. The Upper Midwest Environmental Sciences Center, a branch of the USGS, has equipped ten loons with satellite transmitters in hopes of tracking migration and ultimately discovering physical and biological links to the botulism outbreaks. The loons were tagged in July and their migration can be followed on this website. These transmitters allow researchers to track temperature and pressure, as well as location, which they hope will reveal foraging information. Other loons were also tagged with geolocators which will record information that researchers will collect when they remove the tags during the following season.

You can hear the call of a common loon here. For further reading, click here to access our recommended reading list on Great Lakes Birds.

Why Worry About Asian Carp When There Are Quagga?

Dr. Charles Kerfoot, a researcher funded by NOAA and The National Science Foundation, isn't worried about Asian Carp. He says "by the time the carp get here, there won’t be anything left for them to eat," referring to the quagga activity that has been identified in Southern Lake Michigan.

These small European mollusks, about the size of a lima bean, have been discovered in abundance feeding on phytoplankton in Lake Michigan. A doughnut shaped collection of algae and other tiny plants was discovered in winter with the aid of NASA’s new Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Between 10,000 and 15,000 quagga mussels can inhabit one square meter in the soft lake bed and have been found in all of the Great Lakes. Consuming phytoplankton at a rate of five to seven times that of the production rate, the massive number of quagge are excreting enough to stimulate the growth of Cladophora algae (see the DNR article on it here). When the algae dies and decomposes, it eliminates oxygen from the surrounding waters increasing the likelihood of botulism. The predictable result from all this is a decline in lake species starting with smaller ones such as zooplankton, and then continuing on to chub and alewives, eventually leading to even the larger fish that inhabit Lake Michigan.

The Journal of Great Lakes Research has published the article on Kerfoot's research called "Approaching Storm: Disappearing Winter Bloom in Lake Michigan," which is available online, here. For an overview of the topic see the Michigan Tech News release, here.

Lake Superior National Estuarine Reserve

The State of Wisconsin nominated the freshwater estuary situated on the confluence of the St. Louis River and Lake Superior for consideration as the 28th National Estuarine Research Reserve in 2008. NOAA has been working with the reserve state partner, University of Wisconsin-Extension and others, to complete the Final Environmental Impact Statement and Management Plan for the proposed Lake Superior Reserve. The proposed site consists exclusively of public lands and waters owned by the Wisconsin Department of Natural Resources, City of Superior, Douglas County and the University of Wisconsin. The site is a diverse complex of representative terrestrial and aquatic habitats that form a unique freshwater estuary where the St. Louis River empties into Lake Superior. Each of the four components identified as the preferred alternative are within close proximity to each other. The combination of components being considered will provide a wide range of estuarine research and public education opportunities and contribute to the national system of research reserves.

The Federal Register announcement for the Reserve appeared on September 3rd.

[Search help: Click on this link for advanced search and input September 3rd as publication date and search for the term "Lake Superior National Estuarine Reserve". The first hit will be the Federal Register notice.]

Where Does the Salt from Winter Roads Go?

A recently released study conducted by the USGS Wisconsin Water Science Center has shown that streams are being adversely affected by the use of salt for deicing roads, sidewalks and parking lots. The study focused especially on eastern Wisconsin and Milwaukee, but also included other northern U.S. cities.

In eastern and south-central Wisconsin, chloride levels exceeding US EPA chronic water quality criteria were found in 100 percent of urban streams during winter. These chloride levels are the determinant of toxicity in the water. Further, the chloride levels of the water were not declining enough even by the time summer came in order for those streams to be suitable for many aquatic inhabitants. Nationally, 55 percent of northern streams samples chloride levels exceeded US EPA chronic water-quality criteria.

Matthew C. Larsen, the Associate Director for Water at the USGS says: "This study suggests the need for advancements that will reduce salt loads to surface waters." Read the full release: "Many Urban Streams Harmful to Aquatic Life Following Winter Pavement Deicing" on the USGS website. For further reading suggestions, see our recommended reading list on Understanding and Protecting Groundwater.

Asian Carp: The Introduction You May Have Missed

While you have probably heard about the controversy and fears surrounding Asian carp, maybe you missed a bit of the background information. The term Asian carp actually accounts for four different types of fish according to the USDA: black carp, silver carp, the Bighead carp and grass carp. An article written by the California Academy of Sciences on these fish can be seen here.

These fish were originally introduced for the purpose of algae control, but then spread in an unintended manner. They can grow to over 20 feet long and 100 pounds, eating up to 40% of their weight a day in plankton. This causes a danger to the food chain, especially for the bottom of it. Asian carp are also know for jumping out of the water when they are scared or alarmed, which happens somewhat frequently in the presence of boats, since they feed near the water's surface. For a fish this size, unpredictable flight type movements have been known to injure boaters and fisherman. This video can help you get an idea of the movement of these fish.

Yellow Perch Numbers Up In Green Bay

According to the Wisconsin DNR, Yellow Perch numbers are up this year, and are the third highest seen in the last 30 years. This may have to do with increased water temperatures that were present during spring and summer this year, as well as an early hatch. A high rate of mortality among first through third year yellow perch has the DNR concerned. Some causes are hypothesized, including predators such as walleye and/or northern pike, as well as birds called cormorants which the DNR are taking specific steps to control. More about the cormorant can be read here. Fishermen are not suspected as being problematic in this instance because most yellow perch they keep are around 8 inches or more, which typically occurs in the third year. Click here for the full press release from the WDNR.

Lake Superior Bathymetric Lidar Collection is Complete

From NOAA:

Lidar is a laser-based technology used to map land, beach, and underwater elevations. Planes equipped with lidar sensors have been surveying much of Lake Superior’s nearshore bathymetry since early July, and as of August 12, 2010, this bathymetric lidar data collection effort is complete.

Over 900 linear kilometers of data were collected in forty-seven days. This exceeded the requirements of the contract by close to 200 linear kilometers, as the original requirement was for collection of 725 linear kilometers of data. Fugro Lads used the LADS MkII system to collect the bathymetric lidar along the shoreline up to 1000 m lakeward or to the extinction of the laser. The same system was used to collect lidar points on land to approximately 30 m inland, so that this collection could be tied to existing and future topographic lidar collections.

This effort, funded by the Great Lakes Restoration Initiative, was extremely successful and will yield data that is greater than 85% very good or good depth coverage. Data in these categories typically extends out to around 20m depth. The raw data will now undergo a refinement process and a quality assurance process. The final data will be delivered to the federal government’s National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center (Center), and the data will be served from the Center’s Digital Coast website by the winter of 2011. Through this website the data will be available for use, free of charge.

Standardized data protocols for processing, assuring quality, and serving the data will be followed, which means a wide variety of organizations can use these data for many different uses. Uses for this dataset are wide-ranging, including planning for restoration efforts, remediating stamp sands, evaluating essential fish habitat, enhancing navigation, and developing scenarios for lake level drop.

Lake Sturgeon - on a hook and a line

The lake sturgeon hook and line season opens September 4th and runs through September 30th. High water levels in state rivers should make this one interesting.

The 2010 season marks the fourth year that the minimum length for harvesting sturgeon is set at 60 inches, with a one-fish limit per season. There is a catch and release season on a stretch of the Menominee River downstream from the Hattie Street dam to Green Bay.

New this year is a catch and release season on the lower St. Croix River from St. Croix Falls Dam downstream to the Mississippi River from Oct. 1 through Oct. 15 to allow Wisconsin and Minnesota to have the same regulations for the same species. This is not reflected in the Fishing Regulations 2010-2011.

Remember to follow all required fishing regulations and bring your bug spray!
