Drought risk in Utah

Drought in Utah: Geography, Seasons, and Exposure

Utah is one of the driest states in the nation, with much of its landscape classified as arid or semi-arid. Drought is a natural and recurring feature of the state's climate, not a rare event. The state's water supply relies heavily on winter snowpack in the Wasatch and Uinta Mountains; when snowfall is below average, drought conditions develop and intensify.

Drought can occur in any season, but it typically builds over months or years. The U.S. Drought Monitor is the official source for tracking drought conditions across the country, including Utah. The state often experiences multi-year droughts, which can strain water resources for homes, agriculture, and natural ecosystems.

Which areas are most exposed? The Wasatch Front—including Salt Lake City, Provo, and Ogden—is the most populous region and depends on mountain snowpack for its water. Southern Utah, including St. George, has a hotter, drier desert climate that makes it particularly vulnerable to prolonged drought. The Uinta Basin and other rural areas also face high exposure, especially where agriculture and livestock are important to the local economy.

Utah's drought risk is rated 5 out of 5 by the National Risk Index, meaning the state is highly susceptible to drought impacts. The Utah Division of Emergency Management coordinates drought response and preparedness efforts across the state.

How it affects homes

Drought itself does not directly cause physical damage to homes like floods or hurricanes, but its secondary effects can be costly for homeowners.

One major concern is soil movement. During extended dry periods, clay-rich soils shrink, which can lead to foundation cracks, settling, and structural damage. This is especially common in areas with expansive soils along the Wasatch Front and in some valleys. Homeowners may notice cracks in walls, uneven floors, or doors that stick.

Drought also increases wildfire risk. Dry vegetation becomes fuel for fires, and homes near wildland areas—the wildland-urban interface—are at greater risk. Wildfires can destroy homes and property, and even after a fire, the soil can become water-repellent, leading to flash flooding and debris flows.

Water restrictions during drought can affect landscaping and outdoor water use. Homeowners may need to reduce irrigation, which can stress plants and trees. In severe cases, municipalities may impose mandatory watering schedules or bans on outdoor watering.

Insurance considerations: Standard homeowners insurance typically covers fire damage, including wildfires. However, damage from drought-induced soil movement, such as foundation cracking, is often not covered. It's important to review your policy and consider additional coverage if you live in a high-risk area. Some insurers may offer endorsements for foundation damage, but availability varies. Also, after a wildfire, insurance may cover rebuilding, but check your limits and keep an up-to-date home inventory.

How to prepare your home

Taking steps now can reduce your risk and help you cope with drought conditions. Here are concrete actions:

• Create defensible space: Clear dry vegetation, dead leaves, and debris within at least 30 feet of your home, or more if local fire officials recommend. Use fire-resistant landscaping and keep gutters clean.
• Install WaterSense labeled fixtures: Upgrade to low-flow toilets, showerheads, and faucets. Fix leaks promptly. The EPA WaterSense program provides guidance on efficient products.
• Implement drought-tolerant landscaping: Replace thirsty lawns with native or drought-tolerant plants. Use mulch to retain soil moisture and reduce evaporation.
• Manage soil moisture around your foundation: In areas with expansive clay, maintain consistent moisture by watering deeply but infrequently, especially during drought. This can help prevent soil shrinkage and foundation cracks. Be sure to follow any local water restrictions.
• Install rain barrels or cisterns: Collect rainwater for outdoor use, where allowed by local regulations. This can reduce demand on municipal supplies.
• Check your insurance coverage: Review your homeowners policy to understand what is covered for wildfire and foundation damage. Consider additional coverage if needed. Talk to your agent about your specific risks.
• Have a wildfire evacuation plan: Know your routes and have a go-bag ready. Sign up for local emergency alerts through your county or the Utah Division of Emergency Management.
• Stay informed: Follow the U.S. Drought Monitor and Drought.gov for current conditions and outlooks. Adjust your water use accordingly.

Frequently asked questions

Why is Utah rated 5 out of 5 for drought risk?

Utah is rated at the highest level because much of the state is arid, water supplies are highly dependent on variable snowpack, and drought can have widespread impacts on water availability, agriculture, and wildfire risk. The National Risk Index considers historical drought frequency, severity, and expected losses.

How does drought affect my home's foundation?

During drought, clay soils lose moisture and shrink, which can cause the ground to pull away from your foundation. This can lead to cracks, uneven floors, and structural damage. Maintaining consistent soil moisture around your foundation and ensuring proper drainage can help mitigate this.

Does homeowners insurance cover drought damage?

Generally, standard homeowners insurance does not cover damage from drought itself, such as foundation movement due to soil shrinkage. However, fire damage from wildfires—which are more likely during drought—is typically covered. Review your policy and talk to your agent about your specific risks.
