Drought risk in Maine

Drought in Maine: What to Expect

Drought is a recurring natural hazard in Maine, though it is less frequent and often less severe than in the arid West. The state is rated level 2 out of 5 for drought risk by HomeRiskMap, indicating a moderate hazard. Maine's climate is generally humid, with ample annual precipitation, but extended periods of below-normal rainfall, above-normal temperatures, and low snowpack can trigger drought conditions that affect water supplies, agriculture, and wildfire potential.

Drought in Maine often develops during the summer and fall, when high temperatures and increased evaporation stress water resources. “Flash droughts” — rapid-onset dry spells — can also occur, catching homeowners off guard. Winter drought matters too: when snowfall and snowpack are below normal, spring recharge of groundwater and streams can be limited. The U.S. Drought Monitor is the official source for tracking drought conditions across the state, and Drought.gov provides state-specific updates and outlooks.

While drought can touch any part of Maine, impacts are often most acute in areas that depend on private wells, shallow groundwater, and small municipal systems. Northern, eastern, and parts of central Maine have experienced notable drought episodes in recent years, but the southern and coastal regions are not immune. Homes on sandy or rocky soils may see water levels drop quickly, while those near larger rivers or lakes may be less affected. Regardless of location, prolonged dry weather can lead to water restrictions, reduced streamflows, and increased wildfire risk.

How it affects homes

For homeowners, drought is primarily a water-supply and foundation concern, with secondary risks from wildfire and landscape loss. The most common impacts include:

• Well water shortages: Many Maine homes rely on private wells. During drought, water tables can fall, causing wells to run dry or produce less water. Shallow or dug wells are especially vulnerable.
• Foundation and soil movement: As soils dry and shrink, especially clay-rich soils, foundations can settle or crack. This can lead to uneven floors, wall cracks, and sticking doors or windows.
• Landscaping damage: Lawns, gardens, and ornamental trees may wither or die without irrigation, and replacing mature landscaping can be costly.
• Wildfire threat: Drought dries out vegetation, increasing the risk of wildfires that can damage or destroy homes, especially in wildland-urban interface areas.
• Water restrictions: Local utilities may impose mandatory outdoor watering bans, affecting pools, car washing, and garden irrigation.

Insurance considerations are important. Standard homeowners policies typically do not cover drought-related damage such as a well going dry or foundation cracking from soil shrinkage. These are often considered maintenance issues or fall under earth movement exclusions. However, if a drought-fueled wildfire damages your home, fire damage is generally covered. Some insurers offer endorsements for water backup or well protection, but coverage varies. Review your policy and talk to your agent about what is and isn't covered.

How to prepare your home

Preparing for drought in Maine involves conserving water, protecting your foundation, and reducing wildfire risk. Here are concrete steps:

• Monitor drought conditions: Check the U.S. Drought Monitor and Drought.gov regularly, and follow guidance from the Maine Emergency Management Agency.
• Conserve water indoors: Fix leaks promptly, install EPA WaterSense-labeled fixtures (toilets, showerheads, faucets), run dishwashers and washing machines only with full loads, and take shorter showers.
• Conserve water outdoors: Use drought-tolerant native plants, apply mulch to retain soil moisture, water early morning or evening, and consider drip irrigation. Rain barrels can capture roof runoff for outdoor use where allowed.
• Maintain your well: Have your well inspected and water level checked periodically. If your well is shallow or has a history of running dry, consider deepening it or installing a storage tank. Keep a supply of bottled water for emergencies.
• Protect your foundation: During dry spells, maintain consistent soil moisture around the foundation with soaker hoses or mulch, but avoid overwatering. Ensure gutters and downspouts direct water away from the house to prevent erosion and settling.
• Reduce wildfire risk: Create defensible space by clearing dead brush, leaves, and debris within 30 feet of your home. Keep grass short, prune low-hanging branches, and use fire-resistant landscaping materials.
• Review insurance coverage: Understand what your policy covers for wells, foundations, and wildfire. Ask about endorsements or separate policies that might fill gaps.
• Have an emergency water plan: Store at least one gallon of water per person per day for several days. Identify alternative water sources, such as community filling stations or neighbors with deeper wells.

Frequently asked questions

How does drought affect private wells in Maine?

Many Maine homes depend on private wells, which draw from groundwater. During extended dry periods, water tables can drop, causing wells to run dry or produce less water. Shallow or dug wells are most at risk. You might notice sputtering faucets, sediment, or air in your water lines. If your well goes dry, you may need to haul water, reduce usage, or drill deeper. Monitoring groundwater levels and conserving water can help you avoid a crisis.

Does homeowners insurance cover drought-related damage in Maine?

Generally, standard homeowners insurance does not cover damage from drought, such as a well going dry or foundation cracking due to soil shrinkage. These are often viewed as maintenance issues or excluded under earth movement provisions. However, if a drought-driven wildfire damages your home, fire damage is typically covered. Check with your insurer about specific endorsements or separate policies for wells or water backup.

What can I do during a drought to conserve water at home?

Follow any local water restrictions first. Indoors, fix leaks, run full loads in appliances, take shorter showers, and install WaterSense-labeled fixtures. Outdoors, water early morning or evening, use drip irrigation, mulch, and choose native or drought-tolerant plants. You can also capture rainwater for outdoor use where allowed. The EPA WaterSense program offers many practical tips.
