How Franklin County floods

Franklin County experiences a flood risk profile dominated by standard river floods and flash floods, with 58 flood events, 52 flash flood events resulting in 1 death, and 4 tropical storm events recorded over the last 30 years. Recent impacts include ice jam flooding along various rivers on March 17, 2025, when rain and snowmelt runoff caused the Carrabassett River in Kingfield to overflow and flood properties. Additionally, heavy rainfall from the remnants of Tropical Storm Beryl on July 10, 2024, brought 3 to 5 inches of rain over a 36-hour period following saturated ground conditions from previous storms.

National Flood Insurance Program claim data shows that properties in Zone A carry the heaviest risk burden, accounting for 59 claims with an average payout of $33,039 and an average recorded water depth of 9 inches. Properties categorized under Zone UNKNOWN recorded 18 claims with an average payout of $3,637 and an average water depth of 3 inches, while Zone X properties logged 10 claims with an average payout of $25,248 and an average water depth of 2 inches. One claim was recorded in Zone X_SHADED with an average payout of $2,262 and an average water depth of 1 inch. Residents in Zone A and near rivers should pay the closest attention to flood risks given these historical claims and water depths.

From the storm reports

Flood · Mar 17, 2025. The combination of rain and snowmelt runoff on March 17 was sufficient to produce ice jam flooding along various rivers in the Western Maine Mountains. Most of the ice remained within the streambanks, with the exception of the Carrabassett River. An ice jam on the Carrabassett River in Kingfield resulted in flooding of properties.

Flash Flood · Jun 24, 2024. A cold front stalled over the region with an area of low-pressure riding along it, becoming a focal point for shower and thunderstorm development. The steering winds were under 5 miles per hour, allowing storms to stall. This resulted in localized flash flooding in Chesterville and China Maine with road washouts in each community.

Flood · Apr 12, 2024. A cold front brought widespread soaking rainfall to the area. This rainfall combined with significant snowpack loss and saturated grounds to produce minor to moderate river flooding, with isolated flash flooding across the mountains. Repeated rounds of rain compressed, warmed, and ripened the area snowpack in advance of the heavier rain on Friday the 12th. The combination of rain, strong winds, and high dew point…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Franklin County

If a building in Franklin County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
