From the storm reports

Flash Flood · Jul 23, 2025. Thunderstorms moved across the region during the morning of the 23rd ahead of a cold front. While the storms were not severe as they reached northwestern Wisconsin, they were producing heavy rainfall. State Highway 35 through Siren was covered by water during the late morning hours following the storms leading to minor traffic issues.

Flash Flood · Aug 26, 2024. Storms developed across Minnesota during the afternoon hours of the 26th across Minnesota and moved into northwest Wisconsin during the evening hours. These storms were mainly wind producing storms with numerous reports of downed trees and power lines across the region. Minor flash flooding was also observed in Siren.

Flash Flood · Jul 27, 2023. Warm and humid conditions developed across northeastern Minnesota on the 27th ahead of a frontal boundary that stalled out across the region. Storms were primarily hail producers across northeastern Minnesota but transitioned to more of a wind threat as they grew upscale across northwestern Wisconsin. Numerous reports of trees and powerlines downed were received across the area with some flash flooding occurring l…

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…

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 Burnett County

If a building in Burnett 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.
