Flash flooding and standard flooding dominate the historical flood profile of Shannon County, Missouri. Over the last 30 years, the NOAA Storm Events Database recorded 79 flood events and 75 flash flood events, which resulted in a total of two deaths.
Severe weather events illustrate this recurring risk. For example, a heavy rainfall system from April 4th to April 6th brought 8 to 10 inches of rain—with localized amounts up to 12 inches—to southern Missouri, resulting in significant flash flooding, minor to moderate river flooding, and two flood fatalities.
Homeowners and real estate agents should pay the most attention to properties located within FEMA Flood Zone A, which accounts for the majority of historical National Flood Insurance Program claims in the county. Properties in Zone A recorded 16 claims with an average payout of $10,809 and an average recorded water depth of 6 inches. Additionally, properties with unknown flood zones should exercise caution, as two claims in Zone UNKNOWN recorded an average water depth of 69 inches with an average payout of $3,147.

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