Four out of five Great Lakes set February water level record
Four out of the five Great Lakes set water level records for the month of February.
Lakes Superior, Michigan, Huron, and Erie had their highest February water levels. Each number in red on this map show how high each lake was above the previous record. Lake Ontario was about five inches below the record for the month, shown in green. Lake Michigan saw the biggest increase from the previous record. The water level increased more than 5.5 inches from the previous record, which was set in 1986.
Here are the official water levels for February according to the US Army Corps of Engineers. These values are given in feet.
Water levels have been high throughout 2020. Lake Michigan also set the record for the highest water level for the month of January to start the year. The high water levels are projected to continue through the summer.
Focusing specifically on Lake Michigan, the February 2020 level was 581.53 feet. As of early March, the value is down slightly, to 581.40 feet. Even though the water level is dropping, the level is still above the record for the month of March also by around four inches.
With high water levels comes increased erosion and shrinking shorelines. This will likely be an issue as we head into the spring season, which is predicted to be wetter than normal. You can read more about this problem in our Washed Away coverage.
