Oklahoma Flood Zone Map
Last updated: August 2026
Oklahoma faces flash flooding from severe thunderstorms, riverine flooding from the Arkansas, Red, and Canadian rivers, and dam failure risks. The state's highly variable climate produces extreme rainfall events that can rapidly overwhelm river systems and urban drainage.
2 of 77 Oklahoma counties are rated high or very high for inland flood risk by FEMA's National Risk Index. 13 communities participate in FEMA's Community Rating System, qualifying residents for flood insurance discounts of up to 45%.
Oklahoma has recorded 12,998 NFIP flood insurance claims since 1978, totaling $259.7M in payouts. See how Oklahoma compares in our nationwide NFIP claims data breakdown.

Levee Protection in Oklahoma
The USACE National Levee Database lists 8 levee systems protecting parts of 5 Oklahoma cities. A system's FEMA accreditation status determines how its protected area is mapped - accredited levees are typically mapped as Zone X, while non-accredited or provisionally accredited (PAL) systems generally leave their protected area in the SFHA.

Oklahoma Flood Zone FAQ
How do I check if my Oklahoma property is in a flood zone?
Enter your OK address in FludZone's free lookup tool. We query FEMA's National Flood Hazard Layer in real-time to show your flood zone designation, whether flood insurance is required, and your property's risk level.
Do I need flood insurance in Oklahoma?
If your Oklahoma property is in a Special Flood Hazard Area (SFHA), meaning zones starting with A or V, and you have a federally regulated or government-backed mortgage, federal law generally requires your lender to ensure you carry flood insurance. Properties in Zone X are not subject to the federal mandate but lenders may still require coverage, and it is often recommended given Oklahoma's flood history.
What are the most common flood zones in Oklahoma?
The most common FEMA flood zone designations in Oklahoma are Zone AE, Zone A, Zone AO, Zone X. Each zone reflects a different level of flood risk, from high-risk areas where flood insurance is generally required for federally regulated or government-backed mortgages to lower-risk areas where coverage is optional but recommended.
Can I remove my Oklahoma property from a flood zone?
Yes, if your Oklahoma property's natural ground elevation was always above the Base Flood Elevation and FEMA inadvertently mapped it in the SFHA, you can apply for a Letter of Map Amendment (LOMA) through FEMA. For properties in Oklahoma's AE and A zones, the LOMA process is relatively straightforward when the elevation data supports it. If your property was raised above the BFE with fill, the process is a LOMR-F. A successful LOMA generally removes the federal mandatory flood insurance requirement, but your lender may still choose to require coverage. You'll need an elevation certificate from a licensed surveyor.
Do any Oklahoma communities offer flood insurance discounts?
Yes, 13 Oklahoma communities participate in FEMA's Community Rating System (CRS), a voluntary program that rewards communities for exceeding minimum flood mitigation standards. Residents in participating communities can receive NFIP premium discounts of up to 45% in the Special Flood Hazard Area. Properties outside the SFHA also benefit: CRS classes 1 through 6 receive a 10% discount, and classes 7 through 9 receive a 5% discount on NFIP premiums. Check your city's page on FludZone to see if your community participates.
How much does flood insurance cost in Oklahoma?
The average NFIP flood insurance premium in Oklahoma is $1,056 per year across 9,760 active policies. Premiums vary by zone: Zone AE policies average $1,254/yr. Under FEMA's Risk Rating 2.0, your specific premium depends on property type, elevation relative to the Base Flood Elevation, and distance to water, not just your flood zone designation.
Which Oklahoma counties have the highest flood risk?
According to FEMA's National Risk Index, Tulsa, Oklahoma are among Oklahoma's highest-risk counties for inland flooding. Overall, 2 of 77 Oklahoma counties are rated "High" or "Very High" for inland flood risk. County-level ratings account for historical flood losses, social vulnerability, and community resilience.
How many NFIP flood insurance claims has Oklahoma had?
Oklahoma has recorded 12,998 NFIP flood insurance claims totaling $259.7M in payouts since 1978. The highest-claim year was 1984, with 1,633 claims and $32.6M in payouts. This history reflects cumulative flood damage to Oklahoma properties across decades of storm and rainfall events.
How many Oklahoma properties have flooded repeatedly?
Oklahoma has 1,064 properties with multiple flood losses. Of these, 173 are classified as Severe Repetitive Loss, meaning they have experienced four or more NFIP claims of $5,000 or more, or two or more claims where the total exceeds the building value. 83 of these properties have been mitigated.
What percentage of Oklahoma homes have flood insurance?
Only roughly 1 in 160 households in Oklahoma carries NFIP flood insurance (0.6% of estimated households). 60 counties in Oklahoma have elevated flood risk but low insurance coverage, indicating a significant protection gap.
Are there levees protecting Oklahoma cities?
Yes. The USACE National Levee Database lists 8 levee systems protecting parts of 5 Oklahoma cities. 4 are FEMA-accredited (generally mapped as Zone X), 4 are non-accredited (the protected area stays in the SFHA), and 0 are provisionally accredited (PAL, accreditation in progress). Levee protection is system-specific, not citywide - check a specific city's page or use the address search above for the zone at a specific property.
