The U.S Army Corps of Engineers is reporting a resurgence in Great Lakes water levels. After years of record-setting lows the frigid winter and ice coverage of the Great Lakes offers hope of lake level recovery. They report, “Lakes Superior and Michigan-Huron are 12 and 14 inches, respectively, above their levels of a year ago. Lake St. Clair is 2 inches lower while Lakes Erie and Ontario are 3 and 6 inches, respectively, above what they were at this time last year. Over the next 30 days, Lake Superior is expected to drop 2 inches and Lake Michigan-Huron is expected to remain near its current level. Lakes St. Clair and Erie are expected to rise 10 inches and 3 inches respectively over the next 30 days while Lake Ontario is expected to drop 1 inch. Ice building in the connecting channels can cause significant water level fluctuations, especially in Lake St. Clair.”
Meanwhile NOAA is recording slightly above normal levels at Harbor Beach with approximately 2 inches above datum.
