Drought Risk in Wyoming — Level 4 of 5

Wyoming is rated level 4 of 5 for drought risk on the National Risk Index. Drought affects water supply, can cause foundation and landscaping damage, and increases wildfire risk. Homeowners should understand the hazards and take proactive steps to conserve water and protect their property.

Understanding Drought in Wyoming

Wyoming's arid and semi-arid climate makes drought a recurring natural hazard. The state experiences an average of less than 10 inches of precipitation per year in many lower-elevation areas, though mountain regions receive more as snow. Snowpack acts as a natural reservoir, slowly releasing moisture through spring snowmelt. When snowpack is low or summer temperatures are extreme, drought conditions can quickly develop.

Drought in Wyoming can occur in any season, but it typically becomes most visible in late summer and fall. According to the U.S. Drought Monitor, large sections of Wyoming have experienced severe to exceptional drought in recent years. The most exposed areas are generally the lower elevations, including the Powder River Basin, the Bighorn Basin, and the Wyoming High Plains, where agricultural irrigation depends heavily on surface water and groundwater. Mountain communities can also face increased water supply pressure when snowpack fails to accumulate.

Because Wyoming is ranked at level 4 of 5 on the National Risk Index for drought, homeowners should understand that drought is both a water supply issue and a property hazard. The Drought.gov database shows that some Wyoming counties have experienced long-term drought episodes lasting years, which raises the likelihood of cumulative impacts on homes and infrastructure.

How It Affects Homes

Drought can damage homes in several ways, even though it is not a sudden event like a storm. The most common issue is soil shrinkage. As ground moisture dries out, clay-rich soils contract and settle. This can cause foundations to crack, driveways to sink, and exterior walls to shift. If soil dries unevenly, it may also pull on underground utility lines.

Another serious problem is the loss of landscaping. Lawns, trees, and shrubs can die, leading to increased erosion and dust near the home. In extreme drought, dead vegetation may also increase wildfire risk. According to the Wyoming Office of Homeland Security (hls.wyo.gov), drought-related wildfires have forced evacuations and destroyed homes in past years.

Well-water dependent homes are especially vulnerable. When the water table drops during a drought, wells can run dry or pump sand and sediment. This requires expensive drilling or redevelopment and may also affect water quality. Homeowners with private wells should monitor output closely during dry periods.

Insurance considerations are important. Standard homeowners insurance policies generally do not cover damage caused by earth settlement, foundation cracks, or seepage from dry soil. Damage from wildfires is typically covered, but some insurers have raised rates or non-renewed policies in drought-prone areas. If you experience a burst pipe from sudden freeze after a dry spell, that may be covered, but it is not directly a drought loss. Review your policy with your agent to see whether you need supplemental coverage for groundwater-related issues or increased wildfire protection.

How to Prepare Your Home

Preparing for drought reduces its impact on your home and water supply. Consider these steps:

Conserve water indoors. Fix leaks, install low-flow fixtures, and run washing machines and dishwashers only with full loads. The EPA WaterSense program (epa.gov/watersense) offers guidance on water-efficient upgrades.
Make your landscaping drought-tolerant. Replace turf with native or low-water plants. Mulch flower beds to retain soil moisture. Use drip irrigation instead of sprinklers.
Protect your soil and foundation. Keep a consistent level of soil moisture around your foundation. Use soaker hoses or adjust downspouts so water doesn't pool in one area. Installing a foundation watering system can help prevent differential settling.
Check and maintain your well. Have your well professionally tested for flow and water level. Store water containers for emergency use if you rely on electricity for pumping.
Create defensible space against wildfire. Clear dead brush, keep grass short, and store firewood away from your home. Follow local fire codes.
Reduce rainwater runoff. Install a rain barrel to capture roof runoff for outdoor plants, but check local regulations first.

Frequently Asked Questions

Does homeowners insurance cover drought damage?

In general, standard homeowners insurance does not cover drought-caused foundation movement, cracked pavement, or soil settlement because these are considered earth movement issues. However, damage from a drought-driven wildfire is typically covered by homeowners insurance. It's wise to review your policy and ask your agent about specific drought-related exclusions.

What is the difference between a drought and a water shortage?

A drought is a natural event defined by a period of unusually dry weather. A water shortage is when water supply fails to meet water users' demands. Drought can cause a water shortage, but water shortages can also occur because of infrastructure failure, high demand, or contamination. The U.S. Drought Monitor provides daily information on drought severity, while their drought impacts page tracks water shortage reports.

How can I tell if my property is at risk for drought impacts?

You can use the U.S. Drought Monitor's national map to see the current drought level in your area. Also, visit Drought.gov's "Compare" tool to view maps and rankings for your county. If you have a well, track your water level over time. Local conservation districts and the Wyoming Office of Homeland Security may also provide drought status updates and recommendations.
