How Oregon County floods

Flash flooding dominates the flood character of Oregon County, accounting for 57 recorded events compared to 34 standard floods over the last 30 years.

Recent history illustrates this severe weather pattern. Multiple rounds of showers and thunderstorms between April 4th and April 6th brought 8 to 10 inches of rain—with localized amounts reaching 12 inches—to southern Missouri, causing significant flash flooding, minor to moderate river flooding across south central Missouri, and two flood fatalities in West Plains. Later, on June 29th, early morning thunderstorms produced localized flash flooding alongside severe winds across the region.

National Flood Insurance Program claims data indicates that properties located within FEMA Zone A face the highest risk, accounting for 37 total claims with an average payout of $13,455 and an average recorded water depth of 8 inches. By contrast, Zone X and Zone UNKNOWN recorded only one claim each, with average payouts of $3,089 and $4,617 respectively, and average recorded water depths of 0 inches. Homeowners and real estate agents with properties situated in Zone A should pay the closest attention to flood preparedness and insurance requirements.

Where the flood claims came from

Less than 1% of Oregon County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

In flood insurance claims here that reported a flood depth, the average was 8 inches.

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 Oregon County

If a building in Oregon 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.
