In recent decades, cultural eutrophication of coastal waters and inland lakes around the world has contributed to a rapid expansion of harmful cyanobacteria (blue-green algae). Potential outbreaks of toxin-producing cyanobacteria species have drawn concern from health officials and water managers given their negative ecological, aesthetic, and socioeconomic impacts. Currently, little information regarding expected summertime cyanobacteria abundance is available prior to the season. With sufficient lead time, communicating the likelihood of elevated cyanobacteria abundance may be informative for proactively managing potential threats to lake and beach safety. We developed a model to issue predictions in early June of expected summertime cyanobacteria abundance for Lake Mendota. The prediction model demonstrates moderate to good skill and an ability to accurately predict summers with above-normal cyanobacteria abundance. Associated beach closure predictions also show promise but are highly sensitive to the short observational record – a limitation directly being addressed by Clean Lakes Alliance volunteer monitors and researchers at UW-Madison.

About our Speaker

Dr. Paul Block is an associate professor in civil and environmental engineering at the University of Wisconsin – Madison. His research focuses on hydroclimatology and water resources systems, with a goal to couple climate, hydrology, and management models and knowledge to reduce risks and promote sustainability of water resources for societal benefit. He is involved in many national and international projects that promote season-ahead forecasts as a means to inform decision-making, with applications to reservoir operations, agricultural planning, water quality assessment, and disaster management. He also has extensive experience as a licensed civil engineer working on groundwater protection and extraction, landfill management, and storm water control projects.

This event will be held at The Edgewater hotel - grand ballroom level 5 (1001 Wisconsin Pl, Madison, WI 53703). Doors open at 7:30 a.m. The program runs from 8 - 9 a.m. A Q/A session will follow the presentation as time allows. Complimentary event parking will be available at The Edgewater parking ramp. Parking spots fill up quickly and may be limited depending on hotel capacity.

A Zoom link will be sent to all registrants via the Eventbrite confirmation email.

Clean 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 presenting sponsors First Weber Foundation and Johnson Financial Group, hosting sponsor The Edgewater, supporting sponsor National Guardian Life Insurance Company, and media partner WKOW.
