Project: Assessing Uncertainty and Impacts of Climate Change in Historical Estimates of the Great Lakes Water Balance

Abstract

Ensuring continued access to freshwater is an essential part of managing consumptive use, withdrawals and diversions in the Great Lakes system. This is primarily accomplished through the Great Lakes Compact Agreement, administered by the Great Lakes and St. Lawrence Governors and Premiers’ Regional Body and Compact Council. We used the latest findings from the Large Lake Statistical Water Balance Model to better understand historical trends in precipitation, evaporation, runoff and inter-lake flow in support of this Cumulative Impact Assessment.
