Gove County, Kansas Flood Zone Map

FEMA’s digital flood map shows no high- or moderate-risk zones in Gove 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.

How Gove County floods

Flash flooding from summer thunderstorms dominates the flood history of Gove County. Over the last 30 years, NOAA records show 30 flash flood events compared to 11 general flood events.

Recent storms illustrate this pattern. On June 21, 2020, unorganized supercells merged into a line extending from Greeley County to Sheridan County, producing flash flooding in Grinnell, KS that left a vehicle stuck in the water. Later, on September 16, 2024, storms repeatedly moved over the same location following wind gusts up to 67 MPH and 1.5-inch hail, resulting in flash flooding.

Homeowners, real estate agents, and journalists should pay the most attention to properties vulnerable to sudden, intense rainfall and localized runoff generated by slow-moving or training thunderstorm cells.

From the storm reports

Flash Flood · Sep 16, 2024. In the early afternoon of the 16th, scattered storms began to form near the west Kansas border. By the early evening, an organized line of storms began producing wind gusts up to 67 MPH. Over the following hours, a report of 1.5 inch hail was sent in and the storms began to repeatedly move over the same location, leading to flash flooding.

Flash Flood · Jun 21, 2020. Unorganized supercells formed along the dry line in Wallace/Logan counties and moved east into an increasingly unstable air mass. As the cells moved east, they merged into a line that extended from Greeley County to Sheridan County. The storms from this event produced a landspout tornado near Hoxie, KS, up to ping pong sized hail, and flash flooding in Grinnell, KS with a vehicle stuck in the water.

Flash Flood · Aug 20, 2019. Thunderstorms produce isolated hail up to golf ball size and flash flooding in northwest Kansas.

Flood · May 28, 2018. The largest severe weather outbreak of the year began in the morning. The storms activity spread west across Northwest Kansas, eventually expanding into Southwest Nebraska and East Central Colorado. The first tornado of the day for Northwest Kansas occurred near Hill City. No damage was reported from the tornado. The largest hail size reported was golf ball size from multiple locations area. Some of the thund…

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 Gove County

If a building in Gove 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.
