Flash Flood · May 15, 2025. Thunderstorms initiated during the early afternoon hours over northern Cherry County. They then expanded to the south, into northern Lincoln County over the next few hours becoming severe. A second area of strong to severe storms, originating over northeastern Colorado, tracked into southwestern Nebraska later in the evening. The two areas merged, before lifting northeast into South Dakota after midnight. Hail up…

Flash Flood · Oct 12, 2023. A warm front was situated over southern Nebraska on the morning of October 12th. Aided by strong mid level winds, thunderstorms developed along this front and lifted quickly north into central Nebraska during the mid to late afternoon hours of October 12th. Heavy rain was reported with these storms. Broken Bow received 5.45 inches of rainfall in 2 to 3 hours which led to flooding in and around Broken Bow. The 5.45…

Flash Flood · May 12, 2023. A closed low pressure system moved slowly across the northern Plains and spawned multiple tornadoes across north central Nebraska.

Flood · Mar 13, 2019. Historical flooding occurred in north central Nebraska as rivers, creeks and other streams rose due to the combination of snow, rain, and rapid snow melt on top of frozen ground. The greatest flooding occurred along the Niobrara, Keya Paha, Elkhorn and Loup Rivers; Ponca, Long Pine, Victoria and Cedar creeks; and one fatality occurred from the failure of Spencer Dam that is located on the Niobrara River.

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 Garfield County

If a building in Garfield 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.
