The Flooding Character of Kennebec County

River flooding and flash flooding are the dominant flood types in Kennebec County, ME. Between 1994 and 2024, NOAA data recorded 96 flood events and 14 flash flood events. Recent events illustrate these risks, including widespread river flooding and isolated flash flooding in April 2024, driven by rainfall, snowmelt, and saturated ground. In August 2023, heavy rainfall associated with an area of low pressure caused significant flooding across southern interior Maine.

National Flood Insurance Program (NFIP) claims data indicates that properties in Zone A, which have the highest average water depth and payout, experience substantial flood impacts. Properties in Zone X_UNSHADED also show a high average payout, though with fewer claims and a lower average water depth. Homeowners in areas designated as Zone A, or those located near rivers and streams, should pay particular attention to flood risk.
