Forecasts
Flooding impacts along the immediate shore are typically closely tied to wave height. For more inland areas such as marinas, protected harbors, and the lower reaches of some rivers, the average lake level plus storm surge is important.

Factors Affecting Lake Levels
Great Lakes water levels are based upon a combination of multiple factors, including precipitation, evaporation, river flow into the lakes, river flow out of the lakes, and other diversions. The primary driver of water levels are precipitation, evaporation, and river flow into the lakes, also referred to as "net basin supply." The long term trend for both precipitation and evaporation has been upward over the last several decades.
More information about factors affecting lake levels is available from the US Army Corps of Engineers.
