Drought risk in Texas

Drought in Texas: Geography, Seasons and Hotspots

Drought is one of the most frequent and costly natural hazards in Texas, and the state is rated at the highest level (5 out of 5) for this risk. The reason is geography. Texas is enormous and climatically split: average annual rainfall ranges from more than 50 inches in parts of East Texas to less than 12 inches in the Trans-Pecos and far west. The western two-thirds of the state is naturally dry and depends heavily on stored water — reservoirs, spring-fed rivers, and aquifers such as the Edwards and the Ogallala.

Texas droughts also vary in timing. They often build during La Niña winters and springs, when storm tracks shift north of the state and Gulf moisture is limited, then deepen through summer as temperatures and evaporation peak. A single hot, dry season can push a region into severe drought quickly — sometimes called "flash drought" — while other droughts settle in for years. The 2011 drought is a well-documented example of a multi-season event that left many Texas reservoirs far below normal.

Conditions are tracked with the U.S. Drought Monitor, which classifies drought from D0 (abnormally dry) through D4 (exceptional drought). As categories rise, cities and water utilities activate drought contingency plans with staged watering restrictions, and the Texas Division of Emergency Management coordinates with state and local partners on drought and wildfire response.

Where the risk is greatest

• Far West Texas and the Trans-Pecos — the driest part of the state, with the lowest annual rainfall and very high evaporation.
• The Panhandle and High Plains — depends on the Ogallala aquifer, where long-term pumping plus drought can lower water tables.
• The Edwards Plateau and Hill Country — springs, rivers and private wells are closely tied to rainfall and aquifer recharge.
• South Texas and the Rio Grande Valley — recurring dry spells and heavy demand on the Rio Grande.
• North and Central Texas — fast-growing metro areas rely on reservoir storage, so a single dry year can trigger restrictions.

Late spring through early fall is when impacts usually peak, but drought can develop or persist in any season.

How It Affects Homes

Drought seldom damages a house in one dramatic event. Its effects accumulate over months and years, and in Texas the most common problems are:

• Foundation movement. Much of the state sits on expansive clay soils that swell when wet and shrink when dry. As soil pulls away from a slab, uneven movement can crack interior and exterior walls, crack floor tile, cause doors and windows to stick, and open gaps around trim and brick.
• Plumbing and slab leaks. Shifting soil can stress or break water and sewer lines beneath or beside the slab, and repairs plus resulting water damage can be costly.
• Tree and landscape loss. Stressed or dead trees become hazards themselves, dropping limbs and trunks, and dry vegetation becomes fuel for wildfire — which is why drought and wildfire risk often rise together in Texas.
• Water supply limits. Municipal watering restrictions, declining private well levels in rural areas, and higher water bills all affect how a home and yard can be maintained.
• Wildfire exposure. Counties frequently issue burn bans during dry spells, a reminder that drought raises the odds of a fire reaching the property line.

On insurance, accuracy matters: most standard homeowners policies do not cover damage caused by drought, soil movement or settlement, and they generally exclude earth movement. Depending on the policy language, water damage from an accidental pipe break may be covered even when the soil movement behind it is not. Because carriers and endorsements differ, ask your agent directly what your policy excludes, whether any foundation or water-line endorsement is available, and how a claim would be handled. The Drought.gov clearinghouse and FEMA's National Risk Index are useful references for understanding local exposure.

How to Prepare Your Home

1. Know your water source and your city's drought plan. Find out whether you are on a municipal system, a water district or a private well, and review the staged restriction stages your supplier uses.
2. Reduce outdoor thirst. Replace high-water turf with native and drought-tolerant plants, group plants by water needs, and keep a 3-inch layer of mulch to hold soil moisture.
3. Water efficiently. Use drip irrigation or soaker hoses instead of sprinklers where possible, water in the early morning, add a rain sensor or smart controller, and check regularly for runoff and leaks.
4. Upgrade fixtures indoors. WaterSense-labeled toilets, showerheads and faucets cut indoor use, and fixing running toilets and dripping faucets saves water year-round. See EPA WaterSense.
5. Protect your foundation. Maintain consistent soil moisture around the perimeter with a soaker hose rather than flooding, keep gutters and downspouts discharging well away from the slab, and watch for new cracks or sticking doors as early warning signs.
6. Care for mature trees. Water deeply and infrequently at the drip line, keep mulch away from the trunk, and avoid heavy pruning or fertilizing a tree that is already drought-stressed.
7. Capture free water. Rainwater harvesting with barrels or cisterns is encouraged in Texas, and air-conditioner condensate can be directed to plant beds. Check local rules and any homeowners association requirements.
8. Plan for wildfire while it is dry. Clear dead vegetation and debris from the first few feet around the home and keep roofs and gutters free of leaves.
9. Store emergency water. Ready.gov guidance suggests at least one gallon per person per day for several days, plus supplies for pets.
10. Review coverage annually. Re-check your policy limits, exclusions and any endorsements before dry conditions arrive.

Frequently Asked Questions

Does homeowners insurance cover drought damage in Texas?

Generally, no. Standard homeowners policies typically exclude damage from drought, settling and earth movement, so foundation cracks caused by shrinking clay are usually not covered. Some resulting damage — for example, water damage from an accidental pipe break — may be covered depending on your policy wording. Ask your agent to explain your exclusions in writing.

Which parts of Texas are most at risk from drought?

Far West Texas and the Trans-Pecos, the Panhandle and High Plains, the Edwards Plateau and Hill Country, and South Texas are the most consistently exposed because they receive the least rainfall and depend on stored water. However, drought is a statewide hazard: even humid East Texas can experience short, intense dry spells, and metro areas in North and Central Texas can face water restrictions when reservoirs drop.

What can I do during a drought to protect my foundation?

The goal is steady soil moisture, not saturation. A soaker hose run around the perimeter on a consistent schedule during hot, dry weeks helps limit shrink-swell movement. Keep downspouts and drainage away from the slab, avoid pooling water next to the foundation, and monitor for new cracks, sticking doors or gaps in brickwork so you can call a licensed engineer early.
