FEMA’s digital flood map shows no high- or moderate-risk zones in Sheridan County. That can mean the area was never studied in detail or has no digital map, not that it can’t flood; the county floodplain administrator can say which.

Share of the whole county outline, rivers and lakes included; parts FEMA hasn’t mapped count as zero.

From the storm reports

Flash Flood · May 25, 2023. In the late morning of the 25th, a line of storms from eastern Kansas restrengthened as they slowly moved northwest. These storms dumped upwards of 6 inches of rain near Hoxie and caused flooding in various locations in northwest Kansas. As the day progressed, more storms began firing to the west from the outflow of this initial system. In the afternoon of the 25th, these new slow moving, high precipitation thunde…

Flash Flood · May 10, 2023. During the afternoon hours, scattered storms developed over Northwest Kansas as a warm front moved north. These storms produced hail ranging from pea to golf ball in size and a brief tornado near the town of Selden. The largest hail fell near the towns of Selden, Levant, and Edson. Heavy rain with amounts up to five inches produced flash flooding over portions of Thomas and Sheridan counties. These storms also pr…

Flash Flood · May 26, 2019. Thunderstorms in northwest Kansas produced a tornado in Thomas County in addition to several reports of hail, strong winds, and flash flooding from heavy rains.

Flash Flood · Jun 23, 2018. Scattered thunderstorms developed along a west to east weak cold front during the afternoon. Only a few storms were responsible for the hail reports. The largest hail size reported was hen egg in Colby. Prolonged heavy rainfall over Selden caused flooding to occur over part of Highway 83. The highest wind gust reported occurred southeast of Sharon Springs.

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.

  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 Sheridan County

If a building in Sheridan 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.
