Sea Grant Illinois-Indiana

Description:

Water level variability in Lake Michigan, such as the rapid 6 ft rise between record lows in 2013 to near highs in 2020, had substantial impacts along the southern Lake Michigan coast, forcing communities to quickly respond and plan for future changes. To help address this challenge, Illinois-Indiana Sea Grant (IISG) hosted a series of four virtual workshops in October 2020, focused on improving communication about water level variability along the Lake Michigan coast of Illinois and Indiana. This factsheet summarizes the need, goals, and outcomes of the workshop series, and highlights key resources developed by IISG to address prioritized datasets and outreach products identified in the workshops.
