FEMA’s digital flood map shows no high- or moderate-risk zones in Beaver County. That can mean the area was never studied in detail or has no digital map, not that it can’t flood; the county floodplain administrator can say which.

Share of the whole county outline, rivers and lakes included; parts FEMA hasn’t mapped count as zero.

How Beaver County floods

Flash flooding driven by slow-moving summer thunderstorms dominates the flood profile of Beaver County, Oklahoma. Over the last 30 years, the NOAA Storm Events Database records 28 flash flood events compared to only one standard flood event.

Recent weather patterns illustrate this hazard. On May 28, 2023, a discrete supercell formed over Beaver County and remained stationary over the area, producing flooding rains alongside large hail. Another heavy rainfall event occurred from June 18 to June 19, 2024, when a slow-moving cold front combined with abundant atmospheric moisture to generate training showers and thunderstorms across the northern Oklahoma Panhandle.

Historical National Flood Insurance Program records for Beaver County reflect one claim in Zone X, which logged an average payout of $0 and an average recorded water depth of 0 inches. Property owners, real estate agents, and journalists monitoring localized storm hazards and heavy convective rainfall should pay the most attention to these flash flood risks.

From the storm reports

Flash Flood · Jun 18, 2024. A slow moving cold front moved south out of Kansas into the northern Panhandles during the evening of June 18 into the morning of June 19, 2024. The cold front along with upper level dynamics and abundant moisture throughout the atmosphere, combined to form a line of showers and thunderstorms across the northern half of the Panhandles, in particular for the Oklahoma Panhandle. Due to weak flow aloft, the storms mo…

Flash Flood · May 28, 2023. A few discrete supercells formed across the combined Oklahoma and Texas Panhandles on during the afternoon of the 28th, before a complex of storms moved from the northwest to southeast across the combined Panhandles. One of the discrete cells in the afternoon formed over Beaver County in the Oklahoma Panhandle and not only produced hail up to 2.5 in diameter, but also sat over the same area producing flooding rain…

Flash Flood · May 22, 2023. Early in the afternoon on the 22nd, multiple storms developed across the south central to southeastern Texas Panhandle. Some of these storms produced hail up to 1.5 and some heavy rainfall causing flooding in Gray County. Later in the afternoon a supercell developed over Beaver County in the Oklahoma Panhandle with another supercell forming in southwest Kansas before moving into the central and eastern portions of…

Flash Flood · Jul 8, 2023. Early in the evening on the 8th a small cluster of storms moved southeast through Deaf Smith and Randall County from eastern New Mexico. Later into the evening a much larger complex of storms moved into the Oklahoma Panhandle from SE Colorado and SW Kansas, before entering the Texas Panhandle. It was this complex that brought widespread severe wind gusts and some heavy rain into the combined Panhandles. Wind gusts…

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.

  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 Beaver County

If a building in Beaver 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.
