While water levels throughout the Great Lakes continued their natural, gradual seasonal decline in the autumn, drought conditions in certain regions of the Great Lakes accelerated the water level decline in some of the lakes. Water levels in each of the Great Lakes, except for Lake Erie, were currently below long-term monthly averages. At the beginning of February and also for this time of year, Lake Superior was the lowest it has been since 2013, Lakes Huron-Michigan were the lowest since 2014, and Lake Ontario was the lowest since 2003. Lake Erie levels were the lowest since 2014, although they remained about 1 centimeter, or 0.39 inches, above the long-term average. Marine Link (Easton, Ct.), Feb 25, 2025
