Heavy rain and snowmelt combined to produce significant flooding in the northern Adirondacks. Rivers were running high due to melt from an above normal snowpack, then two to three inches of rain fell across the area on April 26 and 27. An additional one to two inches of rain fell on May 3 and 4, prolonging the flood event. Water flowing out of the lakes regions of the Adirondacks were slow to rise and slow to recede.
