From the storm reports

Flash Flood · Jun 29, 2025. Thunderstorms developed ahead of an approaching cold front during the afternoon hours on Sunday (6/29) across central and east-central Wisconsin. The strongest storms produced damaging winds, hail up to half dollar size, and flash flooding as 2 to 3 inches of rain fell across the area.

Flood · Jul 27, 2016. Slow moving thunderstorms, in a moist and very unstable air mass in the vicinity of a nearly stationary front, produced isolated wind damage and minor flooding in central Wisconsin. Rainfall from the storms was heavy enough to cause street flooding near and west of Edgar (Marathon Co.) and in Birnamwood (Shawano Co.).

Flood · Sep 23, 2010. An excessive rainfall event, with amounts of 3 to 6 inches, occurred across parts of central and northeast Wisconsin starting on the evening of September 22 and lasting through the morning hours of September 23. The initial band of heavy rain formed along a warm front that extended across north-central Wisconsin. Additional rains were a result of a cold front that moved across the state on September 23.||The hea…

Flash Flood · Aug 2, 2006. As thunderstorms slowly trekked across central Wisconsin they produced heavy rainfall that caused flash flooding in Marathon county and Shawano county. Rain flooded roads with 10 to 12 inches of water near the Wausau Hospital (Marathon co.), flooded ditches southeast of Wausau, caused water to pond on Highway 29 near Wittenberg (Shawano co.) and flooded ditches, streets and basements in Tigerton (Shawano co.).

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 Shawano County

If a building in Shawano 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.
