Shaded areas are FEMA’s mapped flood hazard zones in and around Duchesne County, Utah. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Flash flooding from summer thunderstorms dominates the flood risk profile in Duchesne County. Over the last 30 years, the NOAA Storm Events Database records 15 flash flood events, resulting in one death, alongside six general flood events.
Monsoonal surges frequently drive these severe weather patterns. For example, an active monsoon surge brought back-to-back days of thunderstorms producing heavy rain, damaging wind gusts, and hail in July 2021, followed by another flash flood event on August 1, 2021. A subsequent deep monsoonal event similarly impacted the region with widespread thunderstorms and flooding on August 1, 2023.
National Flood Insurance Program records indicate six claims in zones classified as unknown, with an average payout of $4,598 and an average recorded water depth of two inches. Homeowners and real estate agents managing properties in unmapped or less-understood risk zones should pay the closest attention to these localized storm-driven hazards.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Duchesne 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.
