Can't remember where I found this, but I had saved it to word until I had time to post. It's good news anyway!
LANSING — Lake Superior’s water level increased rapidly the past few months. Now, it will outflow more water into Lakes Michigan and Huron.
In fact, all of the Great Lakes water levels have risen dramatically this year. Only Lakes Michigan and Huron remain significantly below long-term averages — at 18 inches below.
Lake Superior is only 5 inches below its long-term average. Lake St. Clair is 2 inches below the long-term average. Lake Erie is 2 inches above, and Lake Ontario is 5 inches above the long-term average water level.
Lake Michigan has risen sharply, said Jim Lewis, U.S. Army Corps of Engineers hydraulic engineer. It had the longest way to go to rise to near the long-term average water level.
Lakes Michigan, Huron and Superior have had their fifth largest January-to-June water level rise in 96 years of records.
Lake Michigan has risen 20 inches since January, while Lake Superior is 19 inches higher since March. Lake St. Clair is up 23 inches. Lake Erie is up 22 inches. Lake Ontario’s water level has increased 32 inches.
Several months of above normal precipitation in the Superior drainage basin have lifted the lake considerably. As a result, the U.S. Army Corps of Engineers and Environment Canada performed the regulation plan for Lake Superior.
As of Aug. 1, the outflow of Lake Superior through the St. Marys River locks has been increased 28,248 cubic feet per second, so more water is being let into Lake Michigan and Lake Huron from the St. Marys River. Lewis said if all other factors stay the same, 28,000 cubic feet per second would equal 1 inch of water in Lakes Michigan and Huron in one month.
