Following last year’s record low water levels in the Great Lakes, and in Lake Michigan and Lake Huron specifically, this year’s rains have helped push those levels back towards the historical average. 

From MLive.com: 

“Heavy October rain could help Lake Michigan and Lake Huron continue to rise toward the long term average water level. Lake Michigan – Huron is still 15 inches below the long term average, but is 11 inches higher than this time last year. Slowly the lake level is increasing. The lake levels will likely fall over the next four months. This is a normal cycle. If the lakes don’t fall as much as normal this winter, the lakes are set up to be higher next summer than this summer…

All of this rain can help Lake Michigan – Huron not fall as much as usual in November.”
