There was more water in Lake Superior last month than has ever been recorded in any June since monitoring began in 1918.
Data from the U.S. Army Corps of Engineers shows that the water level surged three inches past the previous June high-water mark, which was established in 1985. The lake is a foot above its historical average for this time of year, but is still three inches below the all-time record, which was set in October of 1985.
Above-average snowfall, significant ice cover last winter, and a wet spring are credited for the surplus.
The Corps projects that, barring a significant drought, the lake will stay near record levels through the summer, but could begin to drop off this fall.
Other Great Lakes are also experiencing historically high water levels.
