Drought to the west of Lake Superior has allowed the lake’s level to drop in August below the seasonal average for the first time in more than 7 years. Tributaries in northern Minnesota that typically flow into Lake Superior were barely flowing and, in some cases, not flowing into the massive lake anymore, due to drought. The St. Louis River, the largest U.S. tributary to Lake Superior, was flowing in August at just 10% normal. Lake Superior generally rises from April through August and then slowly drops from September to March. Duluth News Tribune (Minn.), Sept 7, 2021
