Your Local Risks · Hazard Guide
Drought is a slow-onset hazard. It doesn't break windows or flood streets. It dries wells, strains reservoirs, kills crops, and amplifies wildfire risk over weeks and months. By the time most people notice, they're already in it.
Understanding the hazard
The U.S. Drought Monitor classifies severity from D0 (abnormally dry) through D4 (exceptional drought). At D3 and D4, reservoirs drop to critical levels, agricultural losses mount into billions, and wildfire conditions become extreme. The Dust Bowl of the 1930s remains the benchmark, but severe drought has struck every region of the country in the modern era.
Drought does not stay in one lane. It compounds other hazards. It dries the fuels that feed wildfires, reduces the water available to fight them, stresses power grids as air conditioning demand spikes, and pushes food prices higher as crop yields fall. A drought in the Colorado River basin affects water and electricity in seven states.
Most households don't think about drought until water restrictions are announced or their well runs low. The time to understand your water source, your vulnerability, and your conservation options is before the monitor turns red.
Know your exposure
Your vulnerability depends on your water source, your region's precipitation patterns, and how your local systems handle scarcity.
Municipalities draw from reservoirs, rivers, and aquifers. During severe drought, mandatory water restrictions limit outdoor use first. In extreme cases, supply-side rationing affects indoor use. Know your utility's drought response plan.
Wells tap groundwater, and water tables drop during drought. Shallow wells are the first to go dry. Know your well's depth, your aquifer's recharge rate, and have a backup water plan before the well pump starts pulling air.
Drought reduces vegetation moisture, making landscapes far more flammable. If you live in or near the wildland-urban interface, drought conditions should trigger your fire preparedness review.
Drought reduces crop yields and raises food prices. Rural communities face additional economic stress as farm income declines. Home gardens also suffer without supplemental watering.
Before it worsens
Find out where your water comes from. Municipal supply? Private well? Surface water? Each source has different vulnerability to drought. If you're on a well, learn your well's depth and the historical low for your aquifer. Your county extension office or state geological survey can help.
One gallon per person per day is the planning standard. Fourteen days of stored water for a family of four is 56 gallons. Food-grade containers, stored in a cool dark place, rotated every six months. This is your buffer if supply is interrupted or rationed.
A dripping faucet wastes thousands of gallons per year. Fix leaks, install low-flow showerheads and faucet aerators, and consider a high-efficiency toilet. These changes pay for themselves in normal conditions and become critical during restrictions.
Shift to native and drought-tolerant plants. Apply mulch heavily to retain soil moisture. If you have a garden, drip irrigation uses 30-50% less water than sprinklers. Rainwater collection, where legal, supplements irrigation during dry spells.
When restrictions hit
Water restrictions escalate in stages. Having a plan for each stage means you're never scrambling to adjust.
Reduce outdoor watering to designated days. Shorten showers by two minutes. Run dishwashers and washing machines only when full. These changes alone can reduce household water use by 15-20%.
Outdoor irrigation may be banned entirely. Car washing restricted. Greywater reuse becomes practical: capture rinse water from dishes and laundry for garden use. Know your municipality's specific restriction tiers in advance.
In exceptional drought, per-household water allocations may be enforced. At this stage, stored water becomes your critical buffer. Prioritize drinking water and essential hygiene. Know where your nearest emergency water distribution point would be.
If your well runs dry, options include deepening the well, connecting to municipal supply if available, or hauling water. All of these are expensive and time-consuming during a drought when contractors are overbooked. The time to plan for well failure is before it happens.
