Dickens County, Texas Flood Zone Map

1 federal flood & hurricane disasters

FEMA’s digital flood map shows no high- or moderate-risk zones in Dickens 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 19, 2018. Scattered thunderstorms developed late this afternoon ahead of a dryline, initially in the Rolling Plains and then farther west and in greater number across the southern South Plains through late evening. Strong instability and moderate wind shear resulted in many of these storms becoming supercells, some with destructive hail to 3 inches in diameter, but very few severe wind gusts were reported. The south side…

Flash Flood · Sep 18, 2014. During the third week of September, an unusually moist and unsettled pattern overspread much of West Texas. The majority of this moisture was sourced from the remnants of Pacific Hurricane Odile and contributed to multiple waves of slow-moving showers and thunderstorms punctuated by periods of flooding. The most extensive flooding was noted during the morning and afternoon of the 18th from the northern South Plain…

Flash Flood · May 6, 2008. An active round of severe thunderstorms impacted the west Texas South Plains during the late afternoon and evening of the 6th and continued into the early morning of the 7th. ||Convection originated along a dryline near the Texas and New Mexico border, as well as near a pre-existing weak frontal boundary stretched west-to-east over the southwestern South Plains. ||Many of the thunderstorms were supercellular in na…

Tropical Depression · Aug 17, 2007. Tropical Depression Erin, previously a tropical storm during landfall on the middle Texas coast early on the 16th, brought large amounts of rain to portions of west Texas. This rain fell primarily on the 17th and 18th of August on the South Plains and Rolling Plains before the system moved northeastward over Oklahoma. ||Erin maintained a defined circulation well after making landfall, and even strengthened signifi…

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 Dickens County

If a building in Dickens 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.
