Water Damage Restoration in Dimmit County, TX
The Nueces River drains most of Dimmit County, crossing its northeastern quarter past Carrizo Springs, where a July 2026 Flood Watch again put low-lying land near the river at risk. The service provides 24/7 connection to vetted local water-damage restoration pros.
Water damage in Dimmit County usually arrives with brief, intense storms rather than steady rain: the county averages only 19.8 inches of precipitation a year but sits along the flood-prone Nueces River. Federal disaster declarations here total 17, and in July 2026 the National Weather Service issued a Flood Watch and Flood Warning as the Nueces River near Asherton rose toward moderate flood stage.

Why Dimmit County homes flood
Dimmit County sits in semi-arid brush country, averaging 19.8 inches of rain a year — but that total tends to arrive in bursts, and the flat-to-rolling terrain drains through loamy and clayey soils that shed water rather than absorb it. The Nueces River crosses the northeastern quarter of the county, and the river gauge near Asherton is the local benchmark: minor flooding begins at 20 feet, moderate at 24, and major at 27. The record crests, 33 feet in June 1935 and June 1913, remain the ceiling; more recent highs include 30.21 feet in July 2002 and 29.97 feet in October 2018.
Risk here is lowland and riverine rather than urban. Federal records count 17 declared disasters for the county, among them two flood declarations and four hurricanes, including Hurricane Hanna in 2020. In July 2026 the National Weather Service issued a flood watch and then a flood warning for the Nueces near Asherton, forecasting a crest near 25.8 feet as upstream runoff moved past Carrizo Springs.
For homeowners, that pattern cuts two ways. Nueces flooding builds over days as water works downriver, so low-lying property near Asherton can stay inundated well after the rain stops. The other major source is indoors: the 2021 winter storms produced two federal ice-storm declarations, and freeze-burst plumbing floods a house from the inside. In both cases drying has to start quickly, since saturated drywall and insulation hold moisture and mold follows within days — the water damage restoration guide outlines the general sequence.
Flood repair permits & inspections
Flood-damage repairs in Dimmit County are regulated largely through the National Flood Insurance Program. The unincorporated county and the cities of Carrizo Springs and Asherton all participate in the program, so repairing a structure in a mapped Special Flood Hazard Area calls for a floodplain development permit before work begins. The unincorporated county issues its own permits through its planning office, while each incorporated city handles work inside its limits. When repair costs reach half of a building's pre-damage market value, the local floodplain administrator classes the work as substantial damage, which can require elevating the structure to the current Base Flood Elevation as a condition of the permit.
| Permit / inspection | When it applies |
|---|---|
| Floodplain development permit — unincorporated Dimmit County | Issued by the county, not a city: required before repairing, rebuilding, or otherwise developing a structure in a Special Flood Hazard Area in the unincorporated county. The county (NFIP community 480789) entered the program's Regular phase on October 1, 2007 and administers floodplain permits for areas outside city limits through its county planning office. |
| Floodplain development permit — City of Carrizo Springs | For repairs in the Special Flood Hazard Area inside Carrizo Springs, the city administers the permit rather than the county. Carrizo Springs (NFIP community 480199) has participated since its Flood Insurance Rate Map took effect July 1, 1987; the City of Asherton (community 480790) participates as well, effective September 1, 1987. |
| Substantial-damage determination (50% rule) | Applied by the local floodplain administrator when a flood-damaged building sits in the Special Flood Hazard Area: if restoring it to its pre-damaged condition would cost 50% or more of the structure's market value before the damage, it is classed as substantial damage and must be elevated to the current Base Flood Elevation. In each participating community the damage is assessed before residents may begin repairs. |
Local water-damage notes
- Nueces River flood waves arrive days after the rain falls upstream — Dimmit County's river flooding is often driven by rainfall that fell well upstream in the Hill Country rather than by local storms. During the July 2026 event, forecasters warned that river flooding "continued to threaten Crystal City and Carrizo Springs and other areas along the Nueces, Frio and Medina Rivers as water pushed downstream," with widespread lowland flooding on the Nueces poised to damage homes around Crystal City and threaten livestock, fencing and roads. Properties near the river can take on water on a clear day, after the local rain has stopped.
- Nueces River near Asherton is the county's river forecast point — The Nueces River near Asherton (USGS station 08193000) is the NWS river forecast point covering the county, and it is the gauge Flood Warnings for the area reference. A Flood Warning was issued for the county on July 15, 2026 by NWS Austin/San Antonio, alongside a Flood Watch issued July 14 by NWS Corpus Christi that ran until July 17. Riverside owners can track the stage at that gauge to judge how much lead time exists before water reaches a structure.
- Carrizo Springs' water supply runs through a single large transmission line — The City of Carrizo Springs has seen its main water source cut by a break in a 20-inch transmission line located roughly four miles outside the city limits. During that outage the city set up non-drinking water distribution at two points, at HEB on North 5th Street and on Wildcat Drive, and asked residents to bring their own containers and conserve while crews repaired the line. A break on that scale can also mean saturated ground and standing water at the failure point.
