Water levels in the Great Lakes are lower than their long-term averages. Despite a wet season, experts believe the gains could evaporate.
After the unusually warm temperatures this summer, lake levels are lower than many would like. Unseasonably warm temperatures have kept ice from forming on many parts of the lakes.
Ice cover slows evaporation because the ice must first melt before the water can evaporate.
Water levels make a difference in shoreline habitat, fish spawning, recreational boating, and the amount of cargo carried in commercial ships.
