From the storm reports

Flash Flood · Jul 4, 2025. A warm front lifted across northwestern Wisconsin the morning of the 4th bringing a very warm and humid airmass to the region. Thunderstorms developed during the afternoon hours with a few being severe across Burnett and Washburn counties. Sporadic wind damage to trees was reported along with some marginally severe hail. Areas just west of the town of Shell Lake in Bashaw Township in Washburn County saw extensive…

Flash Flood · Aug 27, 2024. A decaying complex of storms moved northeast out of east-central Minnesota in the hours after sunrise the morning of the 27th. A few isolated reports of tree damage were received along with a few washed out gravel roads from the heavy rainfall.

Flood · Apr 12, 2023. Record breaking snowfall for the 2022-2023 winter season was received across all of northwest Wisconsin which was about 200% of normal snowfall. Much of this snowpack remained on the ground into April. Warm temperatures 10 to 20 degrees above normal during the second week of the month led to rapid snowmelt across the region with fast rises on area waterways. This above normal warmth was quickly followed by a late…

Flood · Apr 12, 2022. A strong and slow moving area of low pressure moved from the Central Plains on the 12th to over Minnesota on the morning of the 14th and became occluded. A cold front pushed across northwest Wisconsin on the 13th with heavy rainfall being received in some locations. Rainfall totals or 2-3 inches were recorded around Washburn County with most falling in a 5 hour period. Additionally, frost was still in the ground l…

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.

Flood insurance in Washburn County

If a building in Washburn 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.
