Addressing Southern Lake Michigan Water Level Variability Thumbnail
File Type: pdf
File Size: 1.66 MB
Year: 2025

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.

Investigating Crayfish and Freshwater Ecosystems Thumbnail

Year: 2025

The use of live crayfish in classrooms has been identified as a pathway for the introduction of invasive crayfish into our local waterways. To address this issue, the Investigating Crayfish and Freshwater Ecosystems curriculum was developed to teach students about Great Lakes ecosystems, the significance of native crayfish, and the ecological threats posed by invasive crayfish. It contains nine lesson plans aligned to Next Generation Science Standards, Common Core State Standards, and Center for Great Lakes Literacy Principles. The curriculum is best suited for students in grades 6-12 but offers numerous adaptations/extensions to meet the divergent needs of students in grades 2–5.

Regional Water Demand Forecast for Northeastern Illinois, 2020-2050 Thumbnail

Year: 2024

Understanding future water demand is key to managing these resources sustainably. The Chicago Metropolitan Agency for Planning (CMAP), Illinois-Indiana Sea Grant (IISG), and University of Illinois Extension recently updated the region’s water demand forecast to reflect new population and employment projections. The forecast shows that water use is expected to continue declining, due to steady advances in water conservation and efficiency that are outpacing population and employment growth. However, in some areas, forecasted water demand will exceed available groundwater supplies.
