The Nueces River basin is running low. Reservoirs in the Coastal Bend are below historical averages for late May. And a drought assessment released this month places a significant swath of South Texas — from Laredo east toward Corpus Christi — in severe to extreme conditions.

A report this week from RFD-TV added a dimension that most drought coverage skips: fuel cost risk. The connection is real, and it hits Texas households from two directions at once.

What's actually changing

Drought in South Texas is not just a ranching and agriculture story, though it is absolutely that. It also affects energy infrastructure in ways that ripple into your gas tank and electric bill.

Here's the chain: When soil moisture collapses and vegetation dies back, wildfire risk climbs. The state's transmission corridors and pipeline rights-of-way become more vulnerable to fire-related disruptions. At the same time, agricultural diesel demand spikes as irrigators run pumps harder to compensate for dry conditions — competing with commercial and consumer fuel supply in rural distribution networks. Neither of these factors will necessarily produce a dramatic price spike next week. But they tighten margins in a system that is already tighter than it looks.

Separately, ERCOT grid stress is a legitimate concern. Texas air conditioning load in a hot, dry June and July pulls hard on natural gas peakers. When gas demand for power generation rises sharply, wellhead prices and, eventually, retail prices follow. Recent summers have shown that this isn't a theoretical risk.

The drought also hits household water supply in ways that matter for preparedness. South Texas municipalities including those along the I-35 corridor draw from the same stressed surface water sources that ranchers are watching. Smaller communities outside major metros face the most acute exposure.

What we'd actually do

Lock in your fuel costs where you can. If you drive a gasoline or diesel vehicle in South Texas and you have room on a credit card with a consistent payoff habit, consider filling your tank more consistently rather than running low and buying at whatever the pump says. For households with secondary vehicles, keeping tanks above half costs nothing extra and removes a decision point if prices spike or supply tightens locally. This is not hoarding — it is basic buffer management.

Fuel stabilizer is worth having if you store any quantity of gasoline for generators or equipment. In a Texas summer, untreated gasoline degrades quickly in heat. Products like PRI-G or Sta-Bil extend viability meaningfully, and a single bottle costs less than $10 at any farm supply store in the state.

Audit your generator situation before June. South Texas experienced rolling outages in recent summers, and a drought-stressed grid adds risk. If you own a generator, run it under load now — not during an outage. Check oil, check the carburetor if it sat all winter, and confirm you know how much fuel it burns per hour at your actual load. A 5,500-watt generator running a window AC unit and a refrigerator will burn through a 5-gallon can faster than most owners expect.

Map your water backup for a two-week scenario. If your household is on city water tied to a stressed surface reservoir, understand your municipality's current storage levels. Texas Commission on Environmental Quality (TCEQ) publishes drought contingency status for public water systems. Look yours up. If you're on a rural water co-op or a private well, drought conditions can affect pressure and output without warning. A modest stored water supply — FEMA recommends one gallon per person per day as a baseline, which most preparedness practitioners treat as a floor, not a target — is achievable for most families with a weekend's effort.

Reduce discretionary fuel burn through August. Consolidate errands. Combine trips. This sounds obvious. It's also something families actually fail to do until prices sting enough to force behavior change. Getting ahead of that pressure now costs nothing.

The bigger picture

South Texas drought conditions in late May, tracked against historical patterns, suggest this is not a one-month event. The La Niña signal that contributed to drying conditions through spring has not fully reversed. That doesn't mean a crisis is certain — Texas weather is famously unpredictable, and a Gulf moisture event can change conditions within weeks. But planning for durability means building small buffers before you need them, not after.

The goal here is not to stockpile your way into anxiety. It's to make your household slightly less fragile to fuel price volatility and grid stress during a period when both are elevated risks in your region. A full tank, a tested generator, and a honest look at your water situation are three things you can do before the end of next week.
