This document summarizes work completed by Illinois-Indiana Sea Grant (IISG) during the summer and fall of 2023 in support of the Great Lakes Water Quality Agreement (GLWQA) Annex 2 Lake Michigan Partnership. Specifically, IISG is supporting the Lake Michigan Partnership’s activities to determine science priorities for the Cooperative Science and Monitoring Initiative (CSMI) 2025 Field Year on Lake Michigan. The work described herein was sponsored by the International Joint Commission and comprised a 2-day in-person workshop plus a follow-up, online survey. Information contained in this report is intended as guidance only. While it is primarily written to help the Lake Michigan Partnership as the group sets research priorities for the 2025 intensive field year, other researchers and entities studying Lake Michigan might find the document useful.

The role of the Cooperative Science and Monitoring Initiative (CSMI) is to direct enhanced monitoring and research activities across each of the Laurentian Great Lakes to provide relevant information to address the science priorities of each Lake Partnership (established under the Lakewide Management Annex of the 2012 Great Lakes Water Quality Agreement). CSMI is an intensive effort to collect information on the health of one Great Lake each year, cycling through the lakes on a five-year period. In 2020/2021, it was Lake Michigan’s turn (over a two-year period due to COVID). This is an executive summary of the 2020/2021 research results and the associated white paper containing more specific information.
