How Steele County floods

General flooding and flash flooding from summer thunderstorms and snowmelt dominate the flood risk profile in Steele County, supported by 16 flood events and 12 flash flood events recorded over the last 30 years by the NOAA Storm Events Database.

Historical events illustrate these hazards. An April 2019 event demonstrated flooding driven by lingering winter snowpacks and subsequent spring snowmelt affecting low-lying areas and roads. Additionally, an August 2011 event brought severe, slow-moving thunderstorms with very heavy rainfall to the area, impacting communities like Hope with both strong winds and heavy rain.

Properties in FEMA-designated Zone X and Zone D should pay the most attention to this risk. NFIP records show 6 claims in Zone X with an average payout of $31,142 and an average recorded water depth of 0 inches, alongside 2 claims in Zone D with an average payout of $5,203 and an average recorded water depth of 0 inches.

From the storm reports

Flash Flood · Sep 20, 2019. By the late afternoon of the 20th, a weak area of surface low pressure set up near Devils Lake, with the warm front extending out to the east-southeast. Temperatures had risen into the mid 70s to low 80s in the warm sector, with dew points in the upper 60s to lower 70s. To the southwest of the low, a cold front extended back toward Bismarck. Just before 5 pm CDT, a fairly solid line of thunderstorms developed alon…

Flood · Apr 4, 2019. The winter snow melted first on the Minnesota side of the southern Red River Valley. Visible satellite imagery confirmed this fact, showing a distinct snow free north to south band that extended roughly 20 or so miles east of the Red River from Grant to Wilkin to Clay counties. In Fargo, the snow depth fell to zero on April 6th. However, a blizzard from April 10th to 12th brought more snow to the area. This snow f…

Flood · Apr 10, 2011. The winter of 2010-2011 generally brought above normal amounts of snow to the area, but particularly so for the Devils Lake basin, the Sheyenne River basin, and the Wild Rice River basin. By April 1st, snow water equivalents were estimated to be about four to six inches in these areas with about two to four inches elsewhere. A see-saw pattern of temperatures led to a generally slow April snowmelt. At Fargo, the fi…

Flood · Aug 1, 2011. This episode began late in the evening of July 31st and continued into the early morning hours of August 1st, as severe thunderstorms from central North Dakota moved into eastern North Dakota. Many of these storms showed a bow structure, or a structure indicative of strong winds. The storms were also slow movers and several rounds of them tracked over the same area. Hope, ND, was hit by both strong winds and very…

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.

Flood insurance in Steele County

If a building in Steele 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.
