How Piscataquis County floods

River flooding and flash flooding from heavy rainfall dominate the flood history of Piscataquis County, supported by 66 general flood events and 36 flash flood events over the last 30 years, alongside 5 tropical storm impacts. Recent documented events include an ice jam on the Pleasant River in Milo that caused road closures and isolated homes in March 2025, and heavy rainfall from the remnants of Hurricane Beryl that triggered flash flooding in July 2024.

National Flood Insurance Program records indicate that properties in Zone A experienced the highest frequency of claims with 60 claims averaging a $19,422 payout and an average recorded water depth of 4 inches. Properties in Zone X_SHADED recorded higher severity claims, averaging $129,970 with an average water depth of 8 inches across 7 claims. Zone X properties averaged $14,166 with an average water depth of 9 inches across 6 claims, while Zone X_UNSHADED averaged $4,205 with an average water depth of 1 inch across 7 claims, and Zone UNKNOWN averaged $7,584 with an average water depth of 3 inches across 7 claims.

Residents near rivers, low-lying fields, and those located within FEMA Flood Zones A and shaded or unshaded Zone X should pay the closest attention to flood risks.

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.

Cross-section of a river floodplainDiagram: a river valley.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Piscataquis County

If a building in Piscataquis 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.
