Water Level Rises in Great Lakes

April precipitation raised the Mississippi River from worryingly low levels to worryingly high levels, but what about the Great Lakes? Lake Michigan and Huron, in particular, was at risk of setting an all-time low, before the heavy rains last month. The Great Lakes were nearer the edge of the heavy April rains, though, and it takes more water to fill a lake than a river.

It was an extra two inches of rain in April, though, and that was enough to bring Michigan-Huron up to last year’s levels. Water levels are still low enough to cause problems, but it would take a summer drought to take the lake down to record low levels and possibly bring a stop to large-scale shipping.
