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.

With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. 
 
A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. 
 
Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.
