Historic Summer Flooding

Historic late June rains have brought some of the most significant flooding ever seen on the Maumee River during the summer months of June, July or August.  Current river heights are at the highest levels ever seen for this time of year.  The reason why?  An astounding estimated 200 to 300 BILLION gallons of rain fell in the Maumee River Watershed fell on Saturday alone!  Rainfall alone over the past 7 days has been 400 to 600% of normal!
