How Emmet County floods

River flooding and flash flooding from summer storms dominate the flood history of Emmet County, which recorded 71 flood events and 13 flash flood events over the last 30 years according to the NOAA Storm Events Database. Recent regional impacts include heavy rainfall in June 2024 that saturated soils and caused flash flooding, followed by additional storms on June 21 and 22, 2024, that produced widespread 3 to 4 inch rainfall totals, road closures, and significant river flooding that persisted into July 2024.

National Flood Insurance Program records indicate that property damage claims have occurred across different zones. Zone A recorded 16 claims with an average payout of $5,558 and an average recorded water depth of 2 inches. Zone X recorded 2 claims with an average payout of $8,374 and an average recorded water depth of 1 inch. Zone X Unshaded recorded 1 claim with an average payout of $11,576 and an average recorded water depth of 0 inches. Properties located in Zone A and river-adjacent areas should pay the most attention to flood risk given the documented history of heavy rainfall and river overflow.

From the storm reports

Flood · May 24, 2024. There were several rounds of rainfall over the period starting around May 20 through around May 25. This is when there were two rounds of heavy rainfall along with severe thunderstorms including tornadoes and straight-line winds, detailed in respective severe entries for the month. 60-hour rainfall totals ending May 21 at 7pm were up to 4 to 6 inches over portions of Marshall, Tama, Poweshiek, and Jasper Counties.…

Flood · Jun 22, 2024. Heavy rain began late on June 21 and continued into the morning of June 22 as storms persisted along a stalled war front over northern Iowa. A widespread 3-4 inches of rain fell in northern Iowa, resulting in a few road closures across the area. This heavy rain also pushed rivers in northwest Iowa even higher, the catalyst for what would be in some cases catastrophic river flooding in the days to come.

Flood · Jun 21, 2024. Heavy rain fell over portions of northern Iowa, especially northwestern Iowa and bordering states later on June 20 through early on June 21. This rainfall caused flash flooding in portions of northwest Iowa and also aided in saturating the soil. As another round of heavy rain fell later on June 21 into the night and morning of June 22, this rainfall led to renewed flash flooding. This rainfall made its way into st…

Flood · Jul 1, 2024. Significant, and at times record, river flooding in northwest Iowa continued from June into July. Flooding resulted in massive sandbagging efforts, prolonged road closures and damages, and impacts to home and businesses. Continued heavy rain in early July kept some locations in flood through the middle of the month.

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.

Flood insurance in Emmet County

If a building in Emmet 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.
