Wisconsin watershed program involves high schools to collect, share data
A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program. The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch. 
 
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.” 
 
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.

Springfield, Ohio, a college town of 60,000 in southwestern Ohio, sits on the confluence of the Mad River and Buck Creek. Springfield’s streams are as much a part of the city as is Wittenberg University. The streams and the university’s brick infrastructure stand as a constant backdrop to the action of the community but do not often draw attention themselves. 
 
Over the next year, however, Springfield will be paying close attention to its waterways in an effort to eliminate illegal discharges. 
 
“The city is required to determine the location of every pipe that enters Springfield’s streams,” said Sky Schelle, the stormwater coordinator for the city of Springfield. “If a pipe is flowing, we must determine the source of the flow.

Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. 
 
For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. 
 
Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.
