From the storm reports

Flash Flood · Jul 27, 2025. A mid-level wave embedded in the eastern periphery of a developing ridge produced two periods of severe thunderstorms across much of west-central and central MN on Sunday, July 27th. Westerly flow advected in an extremely unstable airmass with favorable amounts of wind shear to support rotating updrafts. Late morning convection occurred across western MN producing quarter size hail and damaging wind gusts across…

Flood · Apr 11, 2023. A near-record snowfall season across Minnesota and Wisconsin led to a snowpack with snow-water-equivilent (SWE) values of 4 to 6 inches across much of the region by mid-March. Below normal temperatures for the first of of spring kept much of the snowpack in tact until the end of the month when it started to melt.||The melt accelerated in early April. On April 08, highs were in the 60s across the region. On April 0…

Flash Flood · Jun 21, 2013. Two rounds of severe thunderstorms occurred across portions of southern and central Minnesota, between Friday afternoon, June 21st and early Saturday morning, June 22nd. These storms first developed across central South Dakota and moved into west central Minnesota after 4 pm, causing large hail, damaging winds and torrential rainfall. ||These storms weakened briefly in central Minnesota, before re-intensifying acr…

Flash Flood · Jun 20, 2013. Several rounds of thunderstorms developed Thursday late afternoon and evening, June 20th, mostly in west central Minnesota, and moved eastward. These storms produced some penny to quarter size hail, but the main event was damaging straight line winds and torrential rainfall during the late evening and overnight period. These storms moved across central and east central Minnesota after midnight, with some redevelop…

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.
