Rainfall and melting snow in the Lake Michigan watershed has resulted in increasing water levels.
The water level of Lake Michigan measured in Milwaukee has been trending upward since early April. Heavy rainfall occurred in Milwaukee on April 8th, 9th and 10th and again on April 17th and 18th. Notice in the below graph how the water level in Milwaukee responded to the influx of rainfall during these periods.
The Lake Michigan water level measured in Milwaukee has increased about two feet since mid-January. Lets hope this gradual upward trend continues through the rest of the Spring.
