From the storm reports

Flash Flood · Jun 5, 2025. Mid-level CVA with surface heating leading to instability, storms initiated along a surface boundary in Colorado. Into the afternoon these storms strengthened and moved into SW Kansas producing a tornado, hail, strong wind gusts, and areas of flash flooding.

Flood · Jun 11, 2015. Both a cold front and an upper level low moving out of the Rockies helped fuel severe thunderstorms during the evening.

Flash Flood · Sep 23, 2014. Thunderstorms during the previous late evening produced heavy rainfall and caused flash flooding across parts of Stevens county.

Flash Flood · Sep 23, 2014. Sustained surface convergence of an unstable atmosphere led to thunderstorms developing during the evening, some of which became severe.

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 Stevens County

If a building in Stevens 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.
