How Schleicher County floods

Flash flooding driven by heavy rainfall and tropical moisture dominates the flood history of Schleicher County. Over the last 30 years, the NOAA Storm Events Database recorded 23 flash flood events, alongside single occurrences of a flood and a tropical depression.

Specific historical events illustrate this risk. In October 2018, an upper-level low pressure system and deep moisture brought heavy rain that caused widespread flooding, forced lakes and rivers above flood stage, and damaged roads and county infrastructure, while Johnson Fork Creek overflowed its banks. Another significant event occurred in September 2018, when a slow-moving trough and Gulf moisture produced devastating flash flooding, hitting the town of Sonora along the Dry Devil's Draw with a wall of water.

Federal insurance records reflect low overall claims activity, with a single claim recorded in Zone X averaging zero dollars in payouts and zero inches of recorded water depth. Residents near creeks, rivers, and low-water crossings, as well as those located in identified flash flood-prone areas, should pay the closest attention to local weather warnings during periods of heavy rainfall.

From the storm reports

Flash Flood · Jul 13, 2025. The combination of deep tropical moisture and a weak upper level area of low pressure produced heavy rainfall and flash flooding across portions of the Northwest Hill Country and Heartland.

Flash Flood · Sep 21, 2018. A slow moving upper and surface trough, an abundance of Gulf of Mexico moisture, and remnants of moisture from a dying Pacific tropical cyclone resulted in devastating flash flooding in part of West Central Texas. The town of Sonora along the Dry Devil's Draw was hardest hit by a wall of water and subsequent flash flooding.

Flood · Oct 16, 2018. An upper level low pressure system remained park across Baja California through October 17. This feature interacted with plenty of moisture and resulted in periods of very heavy rain from October 15 through the 17. ||Widespread flooding developed across the area and many lakes and rivers rose above flood stage and resulted in widespread flooding. Millions of dollars of damage was done to roads and county infras…

Flash Flood · Sep 6, 2018. A cold front moved into a very moist airmass situated across West Central Texas. This clash in airmasses caused some flash flooding across the region.

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.

Flood insurance in Schleicher County

If a building in Schleicher 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.
