      Yahara Lakes 101: Salt and our freshwater lakes Join us for Yahara Lakes 101 to learn about the issues that impact our lakes! About this Talk Road salt is often thought of as an ‘environmentally safe’ chemical. However, at high concentrations, chloride can alter aquatic ecosystems by stressing freshwater species, and deteriorate drinking water sources. For 70+ years, we have applied road salt (sodium chloride) to paved surfaces, without any regard for the environmental consequences. In this month’s Yahara Lakes 101 talk, Hilary Dugan will discuss long-term chloride trends and the state of our lakes across the Midwest and Northeast United States with regard to chloride contamination. We'll also learn what is currently being done locally to curtail further environmental damage.  Additionally, representatives from Wisconsin Salt Wise, a partnership with agencies in Dane County including the Land & Water Resources Department, Madison Metropolitan Sewerage District, and the Madison Water Utility, will be on hand to discuss proper ways to use salt at a home or business. About our Speaker Hilary Dugan is an assistant professor at the Center for Limnology at the University of Wisconsin – Madison. As a limnologist, Hilary studies how terrestrial and atmospheric changes, such as warming air temperatures or land use patterns, alter biogeochemical fluxes and aquatic processes in lakes. Her research balances field based programs, which rely heavily on sensor networks, with the use and development of analytical models, and the application of geophysical and geospatial tools. Her research focus is on temperate and polar lakes, with sites spanning from Wisconsin to Antarctica. One of Hilary’s recent research projects examined long-term chloride trends in over 500 lakes in North America and Europe. She found that many urban lakes in North America have undergone considerable long-term salinization stemming from road salt application. Event Details The event is held at The Edgewater. Come at 7:30 a.m. for a meet-and-greet and to enjoy coffee, pastries, and fruit. The program begins at 8 a.m., and class is dismissed by 9 a.m. Complimentary event parking will be available at The Edgewater. Admission is FREE for Friends of Clean Lakes. If you are not a Friend, admission is $10 per event. Registration for each event is requested for all attendees. Yahara Lakes 101 Lecture Series Yahara Lakes 101 is a series of educational events open to the public and a great chance for residents to learn more about the science behind the issues that affect our lakes. Each month we feature a different expert to make the science accessible and interesting to non-technical audiences. The series is produced in partnership with the UW-Madison Nelson Institute for Environmental Studies, with hosting sponsor The Edgewater, presenting sponsor First Weber Group, supporting sponsor The Evjue Foundation, and media sponsor The Isthmus.
