From the storm reports

Flash Flood · Jul 26, 2020. An approaching cold front interacted with a hot and humid airmass to produce areas of showers and thunderstorms that produced heavy rain across portions of northern Wisconsin during the morning hours. Rainfall amounts ranged from 3 to 8 inches across northern Wisconsin, which produced some flash flooding in some areas. ||Several roads and culverts were damaged as a result of the flooding with several towns declar…

Flood · Jun 11, 2017. More thunderstorms developed later on the afternoon of June 11th in the vicinity of a surface frontal boundary. The storms downed trees and power lines across parts of northern Wisconsin and produced torrential rainfall that caused street flooding in Lac du Flambeau (Vilas Co.), Merrill (Lincoln Co.) and Antigo (Langlade Co.).

Flood · Mar 28, 2004. Warm temperatures late in the month produced a significant, rapid snow melt causing many rivers to rise to near flood stage. On the 28th rainfall amounts of up to an inch fell over the saturated ground and led to even higher river levels.Spring Brook in the city of Antigo (Langlade co.) was already starting to flood before the rain began there. The flooding reached its peak around 7 pm or 8 pm on the 28th and wa…

Flood · Jul 8, 2000. A nearly stationary front across Wisconsin combined with upper air support and abundant moisture to produce a prolonged period of thunderstorms. A few of the storms contained high winds and hail but flooding from heavy rainfall caused the majority of the problems.The heaviest rainfall occurred in an area that extended from southern Vilas county southeast into Manitowoc county. Rainfall totals in this area ranged…

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 Langlade County

If a building in Langlade 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.
