Big Lake Not Yet at Lowest Low 

The water level in Lake Superior was expected to be at 599.8 feet in February, 4 inches lower than the previous month and 19 inches below the long-term monthly average, says the U.S. Army Corps of Engineers.

Even so, Lake Superior was still 2 inches higher than the lowest recorded average for February, from 1926. The Corps is forecasting that lake levels into July should remain slightly above the 1926 record lows. And as the drought has kept its hold on the region, the lack of snow on the western end of the lake has hurt winter tourism businesses and has boosted the likelihood of spring grass fires. The National Weather Service’s Climate Prediction Center suggests improvement in drought conditions in northern Wisconsin and Michigan’s Upper Peninsula along Lake Superior through May.

For northern Minnesota and Lake Superior, the center predicts that the drought will persist.
