Lots of rain in November slowed the seasonal decline of Lake Superior, the International Lake Superior Board of Control reports.
The big lake dropped less than a half-inch in November, a month it usually drops about 2 inches. The Dec. 1 level of the lake was 5 inches above average but 4 inches below this time last year.
The water supply to lakes Michigan and Huron also was up, and those lakes dropped 1 inch in November, less than their usual 2-inch drop. The lakes now sit 7 inches above their long-term average but an inch lower than on Dec. 1, 2014.
The upper lakes generally drop from September to April and then rise from May to August. They are currently holding their own in a higher-than-average trend that's lasted about two years after more than a decade of below-normal water levels.
