With the Lake Michigan lakefront now open to swimmers for the season, the Chicago Park District will be using a new system to monitor bacteria level and ensure a safe swimming environment for visitors. 
 
From The Chicago Tribune: 
“Chicago’s new elaborate system of buoys and statistical models will monitor 16 of the city’s 24 beaches, and Park District officials are seeking grant money from the U.S. Environmental Protection Agency to expand the system to cover all beaches by next summer.
 
The model will predict the levels of harmful bacteria at each beach using data on the location of sources of contamination, like colonies of sea gulls or sewer outlets; the motion of waves that can disturb bacteria growing in the sand; lake-current speeds; water temperature; and sunlight.”

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.Learn more at the link in bio.
