How Pawnee County floods

Flash flooding from severe thunderstorms dominates the flood risk profile in Pawnee County, Oklahoma, accounting for 35 out of 45 recorded flood events over the last 30 years, alongside 10 general flood events.

Recent weather patterns illustrate this hazard, such as a strong upper-level storm system that produced heavy rainfall and flooding on May 20, 2019, and a persistent wet pattern that caused widespread flooding on June 1, 2019. Slow-moving thunderstorms similarly triggered isolated flash flooding on June 7, 2021, and a line of severe storms produced localized flash flooding on June 14, 2025.

Federal insurance claim records indicate that property damage has been concentrated in specific areas, led by Zone A with 5 claims averaging $10,589 per payout and an average recorded water depth of 2 inches. One claim was also recorded in an unknown zone, with an average payout of $790 and an average recorded water depth of 5 inches. Homeowners and real estate agents managing properties within Zone A should pay the closest attention to these localized flash flood and flood risks.

From the storm reports

Flash Flood · Jun 14, 2025. A line of strong to severe thunderstorms moved through portions of eastern Oklahoma during the late morning and afternoon of the 14th, as warm, moist and unstable air was drawn over a stationary front across the area. The strongest storms produced hail up to nickel size, and localized flash flooding.

Flash Flood · Jun 7, 2021. A broad low pressure center in the middle and upper atmosphere moved from northern Texas to northeastern Oklahoma on the 6th and 7th. The first round of thunderstorms affected southeastern Oklahoma during the morning and afternoon hours of the 6th. Locally heavy rainfall occurred, which resulted in isolated flash flooding. ||A more pronounced and focused area of thunderstorms developed during the early morning hou…

Flash Flood · Sep 26, 2019. Thunderstorms developed across northeast Oklahoma during the late evening of the 25th, and continued across the region into the early morning hours of the 26th. The strongest thunderstorms produced large hail up to half dollar size and damaging wind. Additionally, the thunderstorms moved slowly and produced locally heavy rainfall repeatedly across the same areas, which resulted in some flash flooding.

Flash Flood · May 21, 2019. A strong upper level storm system moved into the Southern Plains from the Rockies on the 20th and 21st. The attendant warm front moved from northern Texas northward into northeastern Oklahoma during the day on the 20th, and then the cold front associated with this storm system moved through eastern Oklahoma during the late evening of the 20th and early morning hours of the 21st. Warm, moist, and very unstable air…

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.

  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 Pawnee County

If a building in Pawnee 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.
