Superior levels drop below average

Lake Superior dropped two inches in March, a month it usually drops only a half-inch. The Duluth News Tribune reports the International Lake Superior Board of Control made the announcement late Tuesday.

The lake now sits 13 inches below the long-term average for April 1 and 3 inches below the level at this time last year.

The board said water supply to the entire Lake Superior basin was down from usual, even though snowfall in some areas was up.

Lake Superior will begin its annual, seasonal increase in April as ice and snow melt and rains become more frequent. The lake will rise into September and then begin to fall again.

Lakes Michigan and Huron, meanwhile, rose an inch in March, a month the lakes usually rise 2 inches. That’s not good news for shipping and boating interests worried about low water levels, as the lakes now are 27 inches below their long-term average and 15 inches lower than April 1, 2012.

Northland News Center reports Maude Barlow, national Chairperson of the Council of Canadians and chair of Food and Water Watch's board is embarking on a seven-city speaking tour in Canada and the United States in an effort to protect the Great Lakes.

She will be touring regions of the Great Lakes to talk about threats such as low lake levels, pollution, over-extraction, climate change and invasive species. The tour kicks off today in Duluth.
