Understanding the Water Balance



Details
A major task of the IUGLS was to improve understanding of hydroclimatic conditions in the upper Great Lakes system. This involved assessing the validity of existing methodologies used to determine contemporary estimates of the water balance. Although the existing conventional methodologies used for estimating water balance components have proven relatively successful in the past, questions remain regarding measurement uncertainties associated with the principal components of the Great Lakes water balance (i.e., precipitation, evaporation and runoff). To address these questions, the Study sought to improve accuracy and consistency in net basin supply estimates, including the modification of existing models, development of new models, collection of new data, and improvement of a range of methodologies that have been used for lake level estimation. These analyses were also fundamental to ensuring that any potential future climate outcomes could be understood and attributed to past changes.
