Flash flooding and river flooding from severe thunderstorms equally dominate the flood history of Blaine County, Oklahoma. Over the last 30 years, the NOAA Storm Events Database has recorded an even split of 8 standard flood events and 8 flash flood events. These occurrences are frequently driven by supercell storms, frontal boundaries, and linear thunderstorm systems moving across the region, such as the severe weather and storms that occurred in May 2015, April 2017, and May 2019.
Federal flood insurance claims data shows that flood impacts extend beyond designated high-risk areas, though Zone A properties bear the primary financial burden. Zone A accounts for 5 claims with an average payout of $21,042 and an average recorded water depth of 4 inches. Single claims were also recorded in Zone X and an unknown zone, both resulting in zero-dollar average payouts and zero inches of recorded water depth.
Homeowners and real estate professionals working with properties located within FEMA Zone A should pay the closest attention to flood risks in Blaine County, as these parcels account for the entirety of historical claim payouts and measurable water depths in the area.

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 Blaine 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.
