How Phelps County floods

Flash flooding from severe thunderstorms and heavy rainfall dominates the flood risk in Phelps County, Missouri, accounting for 70 flash flood events compared to 44 general flood events over the last 30 years. Recent storms have demonstrated this hazard, including localized flash flooding and severe weather on June 29, 2025, and June 30, 2025, as well as significant flash flooding and minor to moderate river flooding produced by multiple rounds of showers and thunderstorms between April 4 and April 6, 2025.

National Flood Insurance Program records indicate that properties situated within high-risk Zone A have experienced the heaviest impact, accumulating 215 claims with an average payout of $43,672 and an average recorded water depth of 22 inches. Properties in Zone X have also seen significant claims activity with 62 claims, averaging a payout of $47,567 and an average recorded water depth of 18 inches. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A and Zone X, where historical claims demonstrate a substantial risk of structural water damage and costly repair averages.

Flash Flood · Jun 6, 2025. A round of showers and thunderstorms occurred during the late night hours of June 5th through the morning hours of June 6th. A line of thunderstorms moved into the area from the southwest and caused damaging winds and a tornado. Additional rainfall on June 7th caused flash flooding occurred due to saturated soils.

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 Phelps County

If a building in Phelps 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.
