Drought risk in Colorado

Drought in Colorado: A High-Risk Reality

Colorado's climate is naturally semi-arid, with much of the state receiving less than 20 inches of precipitation per year. The state depends heavily on winter snowpack in the Rocky Mountains, which acts as a natural reservoir, slowly releasing water through spring and summer. When snowpack is below average or spring temperatures arrive early, drought conditions can quickly develop or worsen.

Drought risk in Colorado varies by region and season. The Western Slope, including the Colorado River headwaters, is especially sensitive to snowpack deficits. The Front Range, home to most of the state's population, relies on trans-mountain diversions and reservoirs, making it vulnerable to prolonged dry periods. Eastern Plains communities, with their dependence on groundwater and limited surface water, can also experience severe drought impacts. Summer is the peak season for drought stress, as high temperatures accelerate evaporation and increase water demand from agriculture and cities.

Colorado has experienced notable drought episodes in recent decades, and the US Drought Monitor shows that large portions of the state are periodically classified as abnormally dry or in moderate to exceptional drought. Climate projections suggest that rising temperatures will make droughts more frequent and intense, even if precipitation totals remain similar.

How It Affects Homes

Drought affects homes in several direct and indirect ways. The most common property damage comes from soil shrinkage. When dry conditions persist, expansive clay soils common along the Front Range lose moisture and contract, causing foundations to shift, crack, or settle. This can lead to costly repairs for homeowners, often not covered by standard insurance.

Other impacts include:

• Landscape damage: Lawns, gardens, and trees may die or become stressed, reducing curb appeal and property value.
• Well water outages: Homes relying on private wells may find their water supply depleted, requiring expensive deepening or new well drilling.
• Wildfire risk: Drought dries out vegetation, increasing the risk of wildfires that can threaten homes directly or expose them to smoke and ash damage.
• Water restrictions: Municipalities may impose watering bans, limiting homeowners' ability to maintain landscaping.

Insurance considerations are important. Standard homeowners policies typically do not cover drought-related damages like foundation settlement or cracked driveways, as these are considered gradual or caused by earth movement. Wildfire, however, is covered under most standard policies, but in high-risk areas insurers may raise premiums or decline coverage. Flood damage from post-drought fires or poor drainage is also excluded from standard policies, requiring separate flood insurance.

How to Prepare Your Home

Preparing for drought means both reducing water use and protecting your home from drought-induced damage. Here are practical steps:

• Check and adjust your irrigation system: Install smart controllers that adjust watering based on weather and soil moisture. Water deeply but infrequently to encourage deep root growth.
• Replace thirsty turf: Consider drought-tolerant grasses or xeriscaping with native plants, mulch, and rock. Use resources from the EPA WaterSense program to select water-efficient plants and irrigation practices.
• Fix leaks promptly: Even small leaks in outdoor spigots or underground pipes can waste hundreds of gallons a month. Check your water meter regularly for unexpected usage.
• Protect your foundation: Monitor soil moisture around your home during dry spells. If you see cracks forming in the soil near the foundation, water the foundation perimeter deeply and evenly (if local water restrictions allow). Install gutters and downspouts that direct rainwater away from the house to prevent future expansion.
• Inspect for existing cracks: Seal cracks in your foundation, walls, and pavement before they worsen. Consult a structural engineer if you notice shifting doors or windows.
• Prepare for water restrictions: Install rain barrels (where permitted) to capture rainwater for gardens. Have a plan for prioritizing water for trees and high-value plants during a ban.
• Maintain your well: If you have a private well, test the water level annually and consider installing a low-water alarm. Have a licensed driller evaluate your well's capacity before a severe drought hits.
• Create an emergency water supply: Store at least one gallon of water per person per day for two weeks, and replace it every six months.

Frequently Asked Questions

Is drought a natural disaster in Colorado?

Yes, drought is recognized as a natural hazard in Colorado. The state experiences periodic drought conditions that can lead to agricultural and water-supply emergencies. The Colorado Division of Homeland Security and Emergency Management coordinates drought response and provides guidance to local governments, but drought is rarely declared a federal disaster except in extreme cases when agricultural losses are severe.

Will my homeowners insurance cover drought damage?

Most standard homeowners insurance policies do not cover drought-related damage, including foundation cracks caused by soil shrinkage, dry soil settling, or damage to landscaping. However, if drought leads to a wildfire that damages your home, that loss is typically covered. Contact your insurance agent to understand exactly what your policy includes, and consider purchasing separate coverage for foundation issues if you live in high-risk clay soils.

How can I find out if my area is in a drought?

You can check the US Drought Monitor for weekly updates on drought conditions across Colorado. It provides maps showing areas of abnormally dry, moderate, severe, extreme, and exceptional drought. You can also visit Drought.gov for detailed county-level data, forecasts, and local drought impacts.
