Great Lakes Water Levels

Lake levelsAfter 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 the recent cold winter and wet spring of 2014, water levels have risen providing relief to many areas.  The question of what to do about these changing levels becomes increasingly complex as one considers uncertainty about climate change impacts, relatively stable water levels on the lower Lakes Erie and Ontario, contentious debate over engineering options, and the wide range of affected stakeholders.

Given this challenging context, the Graham Institute and U-M Water Center are developing an Integrated Assessment to consider socially, politically and economically feasible policy and management options for addressing changes in Great Lakes water levels.
