How Muskogee County floods

Flash flooding from severe thunderstorms and heavy rainfall dominates the flood risk in Muskogee County, accounting for 76 recorded events and 2 deaths over the last 30 years, alongside 23 general flood events and 2 additional deaths. Severe storms and heavy rainfall produced flash flooding during events such as June 2022 and August 2024, while widespread showers caused flooding in November 2024.

National Flood Insurance Program records show claims across multiple zones. Properties in Zone A experienced 156 claims with an average payout of $66,450 and an average recorded water depth of 3 inches. Zone X properties recorded 63 claims with an average payout of $89,516 and an average water depth of 8 inches. Unshaded Zone X properties had 25 claims with an average payout of $36,420 and an average water depth of 3 inches, while shaded Zone X properties saw 14 claims averaging $14,736 with an average water depth of 2 inches.

Homeowners, real estate agents, and journalists should pay the most attention to properties in high-risk Zone A, which holds the highest volume of claims, as well as properties located in Zone X where average recorded water depths reached 8 inches during flood events.

From the storm reports

Flash Flood · Apr 28, 2024. Severe thunderstorms developed during the afternoon of the 27th over central Oklahoma, along and ahead of the dry line, as a strong upper level low pressure system deepened into the Southern Rockies. Strong instability and strong wind shear over eastern Oklahoma supported organized severe thunderstorms, including supercells. The first round of storms affected portions of far northeastern Oklahoma during the early…

Flash Flood · Aug 11, 2024. Showers and thunderstorms produced widespread rainfall amounts of two to three inches, with locally heavy amounts up to five inches, across portions of northeastern Oklahoma during the morning of August 11th. This locally heavy rainfall resulted in isolated areas of flash flooding.

Flood · Nov 8, 2024. Widespread showers and thunderstorms developed across eastern Oklahoma on the 8th, ahead of a strong, slow-moving storm system that translated into the Southern Plains from the Southern Rockies. These showers and thunderstorms produced a corridor of locally heavy rainfall in northeastern Oklahoma, which resulted in some flash flooding.

Flash Flood · Jun 10, 2022. Two organized lines of thunderstorms moved into eastern Oklahoma during the morning of the 10th, one from the southwest and one from the northwest. The strongest thunderstorms produced damaging wind. Locally heavy rainfall also occurred in some locations, with a swath of three to six inches falling across Muskogee, Sequoyah, and northern Le Flore Counties, which subsequently resulted in some flash flooding.

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Muskogee County

If a building in Muskogee 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.
