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. Populations of local frog and bird species are also tracked.

Pulse Flow Brings Colorado River Delta Big Benefits

A few years ago, a pulse flow was released into the Colorado River Delta per Minute 319 of the U.S.-Mexico Water Treaty of 1944. The flow began March 23, 2014 and ended on May 18, 2014, pushing around 130 million cubic meters of water downstream. A few months after that, this magazine checked in with some of the scientists involved in monitoring the effects of the pulse flow. Investigators told us they had deployed more than 100 piezometers to study groundwater levels. Flow trackers were giving them discharge data and measurements on salinity were being gathered with conductivity probes. For gauging the impacts to waterfowl, the researchers were using stereos to send out mating calls while listening for responses. But there was so much more data collection underway than we knew.

Lake Erie Infographic

It’s pretty easy to find a Lake Erie infographic these days. And that makes sense, because the water body is an incredibly important one. We laid out some of the dynamics that make it that way in our most recent print edition, published in fall 2016 . Those include its shallow depth, a factor that makes it one of the most productive Great Lakes both for fish and algae. Another is the population surrounding Lake Erie. Did you know that the Erie watershed has nearly 12 million people? That makes it the most populated area of the region! In our latest edition, the Lake Erie infographic serves as a nice background for readers who may be unfamiliar with the lake. It also helps to introduce our coverage of Lake Erie’s western basin.
