Water Levels IA Plan (PDF)

After more than a decade of decline, water levels in Lakes Michigan and Huron reached historic lows in 2013, impacting the economy and ecology of the region. Following cooler and wetter conditions in 2014, water levels have since risen, underscoring the dynamic nature of the Great Lakes system.  Determining what to do about these changing levels becomes increasingly complex as one considers relatively stable water levels on the lower Lakes Erie and Ontario, contentious debate over engineering options, uncertainty about climate change impacts, and the wide range of affected stakeholders.

To help decision makers address the challenges and opportunities posed by Great Lakes water level variability, the Integrated Assessment Center and Water Center at the Graham Sustainability Institute are proposing an Integrated Assessment focused on Lakes Michigan-Huron and Erie, including the Lake Huron to Lake Erie corridor, which asks:

What environmentally, socially, politically, and economically feasible policy options and management actions can people, businesses, and governments implement in order to adapt to current and future variability in Great Lakes water levels?

Planning Grants

The Graham Institute awarded a total of $70,000 to the following seven teams of U.S. and Canadian researchers for six-month planning grants. Running from March through August 2015, the planning grants will examine potential adaptive strategies and identify appropriate localities and partners willing to collaborate in the IA.
