How Woodward County floods

Flash flooding and river flooding equally dominate the flood history of Woodward County, with 14 flash flood events and 13 flood events recorded over the last 30 years. NOAA storm reports illustrate these risks, noting a stationary area of thunderstorms that dropped over five inches of rain and caused flash flooding in portions of Woodward on July 13, 2022, as well as slow-moving thunderstorms that produced isolated flash flooding on September 1, 2022.

National Flood Insurance Program records show that claims are heavily concentrated in high-risk areas. Zone A accounts for the vast majority of claims with 42 filings, resulting in an average payout of $6,610 and an average recorded water depth of 4 inches. Properties located in Zone A should pay the closest attention to flood preparedness, given this historical concentration of claims and water depth. Minimal claim activity is recorded outside of high-risk areas, with only two claims in unshaded Zone X averaging an average payout of $5,529 and an average water depth of 2 inches, one claim in shaded Zone X averaging an average payout of $4,746 and an average water depth of 1 inch, and one claim in an unknown zone with no payout or recorded water depth.

Flood insurance in Woodward County

If a building in Woodward 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.
