This heavy rain resulted in some flash flooding across portions of Buffalo, Trempealeau and Taylor Counties. In Fountain City (Buffalo County), water entered into a home when the levels reached as high as a door. High water covered some city streets in Arcadia (Trempealeau County) and up to a foot of water covered roads in an…

This heavy rain produced flash flooding in parts of Buffalo and Trempealeau Counties. In Buffalo County, Mondovi, Gilmanton and Cream were hit hard by the flash flooding. Water rescues had to be performed in Gilmanton, numerous roads around both communities sustained damaged and were closed and LP tanks were knocked loo…

Flood · Jul 19, 2011. A stationary front was draped across the central portions of Minnesota and Wisconsin. Thunderstorms developed along this front during the evening of July 19th and produced numerous reports of high winds. Some locally heavy rain also occurred which created a little bit of flooding.

Flood · Aug 2, 2011. A low pressure system pushed into north central Wisconsin during the morning hours of August 2nd. Thunderstorms developed along and ahead of the low pressure system and produced very heavy rainfall. The heavy rain filled ditches north of Medford (Taylor County) and a cooperative observer measured 4.00 inches of rainfall near Westboro (Taylor County).

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.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Taylor County

If a building in Taylor 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.
