Water Quality and Hydrology of Whitefish Lake
Whitefish Lake, which is officially named Bardon Lake, is an oligotrophic, soft-water seepage lake in northwestern Wisconsin, and classified by the Wisconsin Department of Natural Resources as an Outstanding Resource Water. Ongoing monitoring of the lake demonstrated that its water quality began to degrade (increased phosphorus and chlorophyll a concentrations) around 2002 following a period of high water level.
To provide a better understanding of what caused the degradation in water quality, and provide information to better understand the lake and protect it from future degradation, the U.S. Geological Survey did a detailed study from 2004 to 2008. The goals of the study were to describe the past and present water quality of the lake, quantify water and phosphorus budgets for the lake, simulate the potential effects of changes in phosphorus inputs on the lake's water quality, analyze changes in the water level in the lake since 1900, and relate the importance of changes in climate and changes in anthropogenic (human-induced) factors in the watershed to the water quality of the lake.

In the News: DNR's sturgeon expert Ron Bruch honored
Year after year, Bruch counts the prehistoric fish as they course through the Lake Winnebago system of lakes and rivers.
Each spring, he wades into the Wolf and Embarrass rivers to look for and tag those fish that survived yet another spearing season.
Bruch has even shared top billing with the large fish in a movie about the Great Lakes and eight years ago brought sturgeon experts from around the world to Wisconsin to tour the sturgeon's breeding grounds.So it's no surprise the Wisconsin Conservation Congress recently named Bruch the state Department of Natural Resources' fishery manager of the year.
"I've been around for 55 years and every fisheries manager we've had has been good, but Ron is exceptional. He listens to the people and works with us," said Dick Koerner of Neenah, an official of the conservation group and part of the DNR's sturgeon advisory committee.
Bruch has worked for the DNR for 32 years and the last 19 years became known as the sturgeon biologist for the Lake Winnebago system, which includes lakes Winnebago, Poygan, Butte des Morts and Winneconne and the Wolf and Embarrass rivers.
"This honor means a lot to me because it came from people I've worked with throughout my entire career, not only in Oshkosh, but in other parts of the state," Bruch said.
To read more of this article, go to the Post-Crescent.
Along with Kathleen Kline and Fred Binkowski of the UW Aquatic Sciences Center, Bruch is a co-writer of People of the Sturgeon: A love affair with an ancient fish, being published this October.

Great Lakes Maps
Take a look at Great Lakes online exhibits, brought to you by Wisconsin's Water Library and University of Wisconsin Sea Grant.
Making Maps, Mapping History
This exhibit traces the evolution of mapmaking since the 1600s and the historical influence of the Great Lakes on the history of Wisconsin. The original maps were collected for an exhibit at the University of Wisconsin-Madison Memorial Library Department of Special Collections, March 19 through June 29, 2007.
The maps are from the UW-Milwaukee American Geographical Society (AGS) Library and the UW-Madison Space Science and Engineering Center. The AGS Library is one of North America’s foremost geography and map collections. The Space Science and Engineering Center includes one of the first remote sensing facilities in the United States.
U.S. Lake Survey
In 1841, Congress created the Lake Survey within the U.S. Army Topographical Engineers, which later became part of the U.S. Army Corps of Engineers. The Survey, based in Detroit, Mich., was charged with conducting a hydrographical survey of the Northern and Northwestern Lakes and preparing and publishing nautical charts and other navigation aids. The Lake Survey published its first charts in 1852. In 1882, after producing 76 charts, it had completed its Congressional mandate.
This pioneering effort eventually grew into a comprehensive program of scientific investigations and monitoring of the Great Lakes conducted through NOAA’s Great Lakes Environmental Research Laboratory (GLERL) in Ann Arbor, Mich.

Film review: Flow
Flow: For the love of water, a film by Irena Salina, takes you to every continent of the world in a quest to understand water as a resource. In Bolivia, for example, the privatization of water leaves poor citizens with dirty water. In South Africa, citizens are asked to pay per use with tokens that the poor cannot afford. Dams are built, but are costly and give off harmful greenhouse gases like methane. Water that is bottled in the United States, while a $40 billon dollar industry, creates trash and its production is unsustainable, especially in its use of petroleum products. Worldwide, multinational corporations are making water a commodity, rather than a natural resource and human right. Major players in the water industry as well as environmental activists concerned with the world water crisis are interviewed in this compelling film.

Zebra Mussels Hang On While Quagga Mussels Take Over
FOR IMMEDIATE RELEASE
For more information contact:
Suzanne Peyer, Doctoral Candidate, smpeyer@wisc.edu, (608) 262-9225
Dr. Carol Eunmi Lee, Professor, UW-Madison Center of Rapid Evolution, carollee@wisc.edu, (608) 262-2675
Editors Note: High-definition video of quagga mussels feeding can be found at www.youtube.com/UWASC. The video is called “Quagga Mussels Feeding.”
MADISON (6/12/2009) --The zebra mussels that have wreaked ecological havoc on the Great Lakes are harder to find these days – not because they are dying off, but because they are being replaced by a cousin, the quagga mussel. But zebra mussels still dominate in fast-moving streams and rivers.
Research conducted by Suzanne Peyer, a doctoral candidate in the UW-Madison Department of Zoology, shows that physiological differences between the two species might determine which mollusk dominates in either calm or fast-moving waters.
“Zebra mussels quite rapidly colonized rivers close to the Great Lakes right after their introduction, within a year or two,” Peyer explained. “Quagga mussels were introduced in the Great Lakes around 20 years ago, but they are still not found in the rivers or tend to be present in low numbers.”

Lake Michigan marine sanctuary
MANITOWOC — Representatives from the National Oceanic and Atmospheric Administration and Wisconsin Historical Society were met with open arms by area divers Wednesday, who seemed excited and pleased at the possibility of opening a marine sanctuary in the area around Lake Michigan.
Ellen Brody, the regional coordinator for the Great Lakes and Northeast Region for NOAA was grinning ear-to-ear after a successful hour-long meeting at Maritime Divers where locals seemed to embrace the possibility of a sanctuary.
"We've been blown away by the support here," Brody said. "I'm not really feeling like there is going to be opposition to this."
The purpose of a marine sanctuary would be to study and preserve the many shipwrecks in Lake Michigan. The study area for the proposed sanctuary begins just north of Two Rivers and stretches through Manitowoc, Cleveland, Sheboygan and Port Washington.

In the News: Lake Delton is back
LAKE DELTON, Wis. -- The last time Bobbie Kochendorfer's family saw Lake Delton was about a year ago -- after the earth gave way and gravity drained the lakewaters into the Wisconsin River.
"You could walk anywhere," she said Monday. "And there was that muck. You know, that stinky muck?"
Several million dollars later, the lake is back, and so is Kochendorfer's family, enjoying the view from an amphibious Duck boat spewing diesel fumes and whoops of joy.
Since heavy rains washed out a berm holding the artificial lake back from the Wisconsin River last summer, engineers, town leaders and the Wisconsin state bureaucracy have moved tons of earth to restore this jewel of the Wisconsin Dells.

U.S. Designates Upper Mississippi River Floodplains a Wetland of International Importance
Secretary of the Interior Ken Salazar today announced approval of portions of the Upper Mississippi River, including the Midwest's largest national wildlife refuge, as a Wetland of International Importance.
In making the announcement, Secretary Salazar said, "The ecological, social, and economic values of the Upper Mississippi River make it one of the crown jewels of this nation's wetlands. This marks the 27th U.S.
wetland designated under the Convention on Wetlands. The U.S. became a party to the convention in 1987, which now includes 150 countries. It's certainly fitting that this area has now officially received international recognition."
The designation includes just over 300,000 acres of federal and state lands and waters of the Upper Mississippi River floodplain from near Wabasha, Minn. to north of Rock Island, Ill. The designation includes all of the 240,000-acre Upper Mississippi River National Wildlife and Fish Refuge headquartered in Winona, Minn. and the adjacent 6,226-acre Trempealeau National Wildlife Refuge in Wisconsin.
Other designated sites in the U.S. include such wetland icons as Okefenokee National Wildlife Refuge in Georgia and Florida, Everglades National Park in Florida, and Horicon Marsh in Wisconsin.

USGS report
Nutrient Trends in Streams and Rivers of the United States, 1993–2003
By Lori A. Sprague, David K. Mueller, Gregory E. Schwarz, and David L. Lorenz
Trends in streamflow and concentrations and loads of total phosphorus, total nitrogen, and nitrate were determined for the period from 1993 to 2003 in selected streams and rivers of the United States. Flow-adjusted trends in concentration (the trends that would have occurred in the absence of natural changes in streamflow), non-flow-adjusted trends in concentration (the trends resulting from both natural and human factors), and trends in load (trends in the nutrient mass transported downstream) were determined, and the results were examined spatially to determine whether a consistent pattern of trends occurred across groups of sites at multiple locations. Relations between the trends and changes in nutrient sources and streamflow are examined.

Rip currents awareness week
Rip Current Awareness Week
June 7-13, 2009
In an effort to heighten public awareness of rip currents at surf beaches, each year NOAA designates the first full week of June as national Rip Current Awareness Week, coinciding with the traditional start of the summer vacation season.
Rip currents are currents of water moving away from shore. The strongest rip currents can attain speeds reaching 8 feet per second; this is faster than an Olympic swimmer can sprint! On average, more people die every year from rip currents than from shark attacks, tornadoes or lightning. According to the United States Lifesaving Association, 80 percent of surf beach rescues are attributed to rip currents, and more than 100 people die annually from drowning in rip currents.
To learn more, go to NOAA's Rip Current Safety website.
