From the storm reports

Flood · Jun 23, 2021. A strong moisture plume with increasing surface instability under a southerly flow aloft produced strong thunderstorms across portions of Deschutes County, OR. These thunderstorms produced heavy rainfall and severe hail at times.

Flood · Jul 1, 2019. Slow moving thunderstorms produced localized flooding and minor mud flows around the Tumalo area during the evening of July 1st. Nearby CoCoRaHS stations just north of Bend reported up to an inch of rainfall with these storms.

Flash Flood · May 21, 2015. A large low pressure system off of southern California would spin up moisture to the area over several previous days. Embedded impulses would enhance convective activity leading up to the day. High CAPE and Perceptible Waters suggested thunderstorms with very heavy rainfall. Several areas across eastern Oregon recorded nearly an inch of rain in 30-60 minutes time. Streets in Bend had been closed of due to st…

Flash Flood · May 28, 2005. Very heavy rain from a thunderstorm led to flash flooding on some streets in Bend, with some debris floating down roadways. One vehicle became stranded at a flooded underpass in Bend. Rainfall amounts from the storm totaled up to 1.25 inches, with .5 inches falling in a 10 minute period.

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.
  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 Deschutes County

If a building in Deschutes 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.
