From the storm reports

Flash Flood · May 15, 2023. A moist southwest flow aloft and building instability at the surface allowed for thunderstorms to develop throughout the day on May 15th. Several thunderstorms that produced periods of heavy rainfall trained over areas of central OR, which result in localized flooding across portions of Crook county.

Flash Flood · Aug 9, 2019. A powerful upper storm system combined with modest low and mid level moisture to yield scattered strong to severe storms and flash flooding. Storms developed first across the higher terrain of central Oregon nearer the Cascades and adjacent Ochoco mountains. Storms then built northward with hail and damaging winds along the way.

Flash Flood · Aug 8, 2019. An approaching storm system combined with modest instability allowed for spotty strong to afternoon storms near the Cascades. The slow moving nature of the storms also lead to heavy rainfall and flooding in at least one area.

Flood · Jan 17, 2011. A large Pacific weather system became established in mid January that produced copious amounts of rainfall with unseasonably warm conditions in parts of Oregon.

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.

  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 Crook County

If a building in Crook 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.
