How Haskell County floods

Flash flooding from slow-moving thunderstorms dominates the flood profile of Haskell County, Oklahoma. Over the last 30 years, the NOAA Storm Events Database recorded 39 flash flood events alongside 5 general flood events.

Heavy rainfall and localized flash flooding occurred during severe weather events in October 2019 and May 2020, driven by slow storm motion and approaching cold fronts that produced locally heavy rainfall across eastern Oklahoma.

National Flood Insurance Program records indicate that flood risks affect properties across multiple zones. Zone A policies accounted for 5 claims with an average payout of $16,653 and an average recorded water depth of 1 inch. Zone X policies recorded 1 claim with an average payout of $98,507 and an average recorded water depth of 1 inch. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within designated Special Flood Hazard Areas (Zone A) as well as properties in moderate-to-low risk areas (Zone X) where severe storms can still produce costly flood damage.

From the storm reports

Flood · May 15, 2020. Thunderstorms developed into eastern Oklahoma during the morning of the 15th. The strongest storms produced damaging wind and a tornado across northeastern Oklahoma. Very moist air across the region, combined with slow storm motion, resulted in locally heavy rainfall and flash flooding. The storms developed slowly southward during the day, with intensification noted as they moved into southeastern Oklahoma, which…

Flash Flood · Oct 10, 2019. Strong to severe thunderstorms developed across eastern Oklahoma during the afternoon and evening of the 10th, as a cold front moved through the region. The strongest storms produced hail up to quarter size and damaging wind.

Flash Flood · Apr 29, 2017. Strong to severe thunderstorms developed during the late evening hours of the 28th over portions of eastern Oklahoma, along and north of a warm front that had moved into the area during the day. These storms produced a strong tornado, hail up to baseball size, damaging wind, and locally heavy rainfall through the early morning hours of the 29th. ||Another round of severe weather developed during the afternoon hour…

Flood · Dec 30, 2015. A strong upper level low pressure system moved from the desert southwest into the Southern Plains in late December. Unseasonably moist air was in place across the region ahead of this approaching system as Pacific moisture in the mid and upper levels combined with very moist air in the low levels from the Gulf of Mexico. Strong atmospheric lift from the approaching upper level low and a warm front moving across th…

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.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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 Haskell County

If a building in Haskell 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.
