Watering Your Foundation During OKC Droughts
Short answer: In a drought, water the soil evenly around your whole foundation to keep clay from shrinking away from it. Lay a soaker hose 1 to 2 feet from the wall, run it slowly with rest breaks, and never pour water straight into gaps.[41] Central Oklahoma got only 71% of normal rain over the past year.[40]
Clay soil shrinks as it dries. When it pulls away from your slab, the foundation loses support and can settle unevenly.[41][29] Steady soil moisture is the goal, not soaking.
How Dry Is It?
- NOAA normal: Oklahoma City averages 36.39 inches of rain a year (1991–2020).[42]
- Last 365 days: Central Oklahoma got 26.62 inches, 71% of normal, from October 14, 2025 through October 13, 2026.[40]
- Last 30 days: Just 1.68 inches, 45% of normal (September 14 to October 13, 2026).[40]
- Summer is the dry stretch. NOAA normals show OKC rain drops from 5.31 inches in May to 3.59 inches in July.[42]
How to Water Around Your Foundation
- Use a soaker hose. NDSU Extension says it lets you water the soil without getting water on the house wall.[41]
- Place it 1 to 2 feet from the foundation, not in the gap next to the wall.[41]
- Go slow. Apply water slowly with rest periods of several hours so it soaks in deep.[41]
- Water the whole perimeter evenly, not just one side.[41]
- Stop if it puddles or runs off, let it soak in, then resume. OSU Extension gives the same advice for watering lawns.[43]
- Water early in the morning. OSU Extension calls it an ideal time to irrigate.[43]
What to Avoid
- Don't pour water into gaps or cracks. NDSU Extension warns that water applied directly into the gap may get into the basement.[41]
- Don't overdo it. The aim is steady moisture. Soggy soil next to the house causes its own trouble.
- Don't let downspouts dump at the wall. OSU Extension says downspouts should drain away from the house.[30]
- Check local rules. Follow your city's watering restrictions during drought.
When Watering Isn't Enough
If cracks keep growing, doors stick or floors slope even with steady watering, the foundation may have already moved. A local pro can tell you what's going on.

Frequently Asked Questions
Should I water my foundation in Oklahoma?
During long dry spells, yes. Keeping soil moisture steady helps stop clay from shrinking away from the slab.[41]
How far from the house should the soaker hose be?
About 1 to 2 feet from the foundation, so water soaks the soil without running into the gap along the wall.[41]
How long should I run the soaker hose?
There's no single number. Run it slowly with rest breaks of several hours, and stop if water puddles or runs off.[41][43]
Can watering fix foundation damage?
No. Watering can help limit soil shrinkage, but it doesn't reverse movement that already happened.
Is OKC in a drought right now?
Central Oklahoma was rated "severely dry" for both the 3-month and 12-month periods through September 2026.[40]
