May 4th Water Levels Report
A wet weather pattern has resulted in heavier than normal rainfall over the last week for the southern portions of the Great Lakes Basin. Rainfall forecasts for the basin call for a continuation of the wet weather pattern with the southern portions of the basin expected to receive another 1 to 2 inches of rain in the next week while the northern reaches are expected to receive less than 0.5 inches.
All of the Great Lakes are above their level of a month ago. Lake Michigan-Huron is 9 inches above its level last month, around 9 inches higher than it was a year ago, and is projected to rise 3 inches over the next month.
Lake Superior’s outflow through the St. Mary’s River, and Lake Michigan-Huron’s outflow into the St. Clair River, are forecasted to be above average in May. Outflows from Lake St. Clair through the Detroit River are also predicted to be above average.
No clear satellite image is available for the entire Bay, but reports are that all the ice has now gone.
