The U.S. Army Corps of Engineers, Detroit District, announces that despite a dry month of February across the Great Lakes basin, water levels on each of the Great Lakes remain very high going into the spring. Lakes Superior, Michigan, Huron, and Erie set new monthly records for February 2020. The records were previously set on lakes Superior, Michigan and Huron in 1986, and in 1987 on Lake Erie.
Although 2020 started with wetter conditions, February was a fairly dry month for the Great Lakes basin with precipitation below average throughout the region. Also, a few cold air outbreaks during the month led to increased evaporation. Late winter and spring is usually a period of seasonal rise on all of the Great Lakes due to increased rainfall and runoff. Water levels typically peak in the summer or early fall. Significant erosion continues in many locations as water levels remain extremely high. Strong storm systems and resulting large waves have led to substantial erosion along much of the Great Lakes coastline.
“After months of generally wet conditions, February was finally drier across most of the Great Lakes.” said John Allis, chief of the Great Lakes Hydraulics and Hydrology Office, Detroit District. “However levels remain above or near record highs for this time of year, and we expect impacts to those along the coastline to increase as water levels now begin rising towards their seasonal peaks.”
The U.S. Army Corps of Engineers urges those impacted by the high water levels in 2019 to prepare for similar or higher levels in 2020. The most recent six-month forecast of Great Lakes water levels still forecasts that water levels could peak very near last year’s record levels.
