Environmental Conditions in Sherman County, Kansas

Radon potential, monitored air quality and current drought status for Sherman County, Kansas, from the Environmental Protection Agency and the U.S. Drought Monitor.

Radon potential

Zone 1

highest radon potential

EPA predicts an average indoor level at or above 4 pCi/L, so the EPA recommends a radon test for every home in this zone, and a mitigation system for new construction.

Air quality (2024)

Median AQI 27Good

2 days at unhealthy for sensitive groups or worse.

90th percentile 58, peak 138 across 324 monitored days.

Drought status

Abnormally dry in 50% of the county

Drought Severity and Coverage Index 50 of 500.

  • D0 Abnormally dry50%

Map of 13 October 2026.

Sources: EPA Map of Radon Zones (September 2025), EPA Air Quality Index (2024) and the U.S. Drought Monitor. A radon zone is a regional planning tool, not a prediction for any individual home — the EPA recommends testing every home regardless of zone. Air quality is shown only for counties that host an EPA monitor. Drought figures describe one weekly map, not a long-term climate average. Compare counties in Kansas.

GIS Data for Sherman County, KS

The Sherman County GIS map on this page loads live federal layers in your browser, so you can check flood zones, terrain, land cover and district boundaries anywhere in Sherman County without a separate GIS login. All of the Sherman GIS data below is drawn from public U.S. government sources.

Layers you can turn on

  • FEMA flood zones

    National Flood Hazard Layer — flood insurance rate map zones and floodways.

  • Elevation contours and hillshade

    USGS 3DEP terrain, so you can read slope and relief across the county.

  • Land cover

    NLCD land cover classes — forest, developed, wetland and water.

  • School districts

    Census TIGER unified and elementary school district boundaries.

  • ZIP code and county boundaries

    Census TIGER ZCTA and county boundary lines.

Where the data comes from

County boundaries come from the U.S. Census Bureau TIGER/Line program, flood zones from FEMA's National Flood Hazard Layer, terrain from the USGS 3D Elevation Program, land cover from the Multi-Resolution Land Characteristics Consortium, and demographics from the American Community Survey.

Property records and tax maps in Sherman County

Most people who look up Sherman County GIS data are after parcel-level records: who owns a property, what it last sold for, and what it is assessed at. Those records are kept locally, not federally, so they are not part of this map. Sherman County property and tax map data lives with the county's own records office, and what that office is called varies by state — Texas counties run an appraisal district (usually searched as a “CAD”), Kentucky uses a Property Valuation Administrator (PVA), and most other states use a county assessor, auditor or tax office. Start with that office for a deed, a tax map number or a parcel boundary; use the map above for flood zones, elevation and land cover on the same land.
