Nearly half the United States is currently in drought — a statistic that most Americans encounter as an agricultural or environmental story. But drought is also a public health emergency, with direct consequences for drinking water quality, heat illness risk, wildfire smoke exposure, food safety, and mental health — and as of the week of June 9, 2026, the condition is worsening, not improving, across wide swaths of the country.
According to the U.S. Drought Monitor — jointly produced by the National Drought Mitigation Center, USDA, and NOAA — 46.93% of the United States and Puerto Rico, and 56.16% of the contiguous lower 48 states, are under active drought conditions as of June 9, 2026. Severe Drought (D2) is actively expanding in the Northeast, Mid-Atlantic, and Minnesota, driven by widespread heat and precipitation deficits. An additional 15% of the country is classified as abnormally dry.
Where the Drought Is — and How Serious
The June 9 Drought Monitor breakdown for the contiguous U.S. tells a sobering geographic story:
- Moderate Drought (D1): 16.4% of the U.S.
- Severe Drought (D2): 18.2% — actively expanding in the Northeast and Mid-Atlantic
- Extreme Drought (D3): 8.8% — including much of the West and parts of the South
- Exceptional Drought (D4): 0.9% — the most severe category
The West remains the hardest-hit region. Utah's Governor Spencer Cox declared a statewide drought emergency after snowpack peaked at just 2.7 inches of snow water equivalent on April 1 — the lowest recorded since 1930. "April 1 snowpack was just 2.7 inches of snow water equivalent, the lowest ever recorded since 1930," Cox said at a press conference at Little Dell Reservoir. Utah's state ecology director described the snowpack as "no-pack," with 93.6% of the state in severe drought and 58.86% in extreme drought as of late May.
Washington State declared its fourth consecutive statewide drought emergency on April 8, 2026 — its fourth statewide emergency since 2015 and the seventh year in the past ten with drought in part or all of the state. The Washington Department of Ecology stated bluntly: "drought is becoming the pattern, our new normal." The state has made $3 million available in emergency drought response grants for affected public water systems.
In the Colorado River Basin — the water lifeline for Phoenix, Las Vegas, Los Angeles, and much of the Southwest — Lake Powell stood at just 25% capacity as of late April 2026 and is projected to continue declining, prompting the Bureau of Reclamation to take unprecedented emergency water-storage actions and raising the prospect of historic lawsuits among basin states.
In Texas, the small town of Mathis — which depends entirely on Lake Corpus Christi for its drinking water — is racing to find alternative supply before reservoir levels fall to the point where the intake valve draws sludge rather than clean water, according to Seven Seas Water Group.

The Health Risks: What Drought Actually Does to People
Drought.gov's public health resource page identifies four primary categories of health impact from drought: decreased water quantity and quality, increased disease, increased mortality, and adverse mental health outcomes.
Drinking Water Quality: As reservoir levels drop and water sources concentrate, naturally occurring contaminants — including nitrates, arsenic, bacteria, and cyanotoxins from algal blooms — can increase in concentration. In San Luis Valley, Colorado, the megadrought is already draining groundwater and increasing concentrations of toxic metals, with few protections for residents drinking from private wells, according to Circle of Blue. Communities that depend on surface water sources, springs, or shallow wells face the highest risk during drought.
Heat Illness: Drought and extreme heat are coupled hazards. When drought reduces soil moisture and vegetation cover, surface temperatures rise further, amplifying urban heat islands. This summer's drought-heat combination is already triggering heat advisories across drought-affected areas. Heat illness — from heat cramps and heat exhaustion to heat stroke — is directly preventable with access to hydration and cooling, which drought complicates. Populations most at risk include outdoor workers, the elderly, infants, and people without air conditioning.
Waterborne Disease: Drought can concentrate waterborne pathogens in smaller volumes of water. When drought breaks with sudden heavy rainfall, the runoff can overwhelm water treatment systems and introduce agricultural runoff, animal waste, and other contaminants. This pattern — drought followed by flood — is increasingly common and is a known driver of waterborne disease outbreaks.
Mental Health: Extended drought affects farmers and agricultural communities with particular severity — threatening livelihoods, forcing difficult decisions about livestock and crops, and driving financial stress. Research consistently links sustained drought to elevated rates of depression, anxiety, and suicide risk in affected agricultural communities.
What Residents in Drought-Affected Areas Should Do
The EPA and CDC offer guidance tailored to different drought scenarios. For residents in drought-affected areas, the most important immediate steps include:
- Check your water source. If you rely on a private well, have it tested for nitrates, arsenic, bacteria, and other contaminants — especially if nearby surface waters are low. Contact your local health department for testing resources.
- Monitor boil-water advisories. Follow your local water utility's communications closely. During periods of very low reservoir levels, treatment capacity may be strained.
- Stay cool and hydrated. Heat and drought co-occur. Know the signs of heat exhaustion (heavy sweating, dizziness, nausea) and heat stroke (hot dry skin, confusion, loss of consciousness). Heat stroke is a medical emergency — call 911 immediately.
- Follow local water restrictions. Many drought-affected municipalities have enacted outdoor watering restrictions. These restrictions exist to preserve drinking water supply.
- Monitor air quality. Drought conditions increase wildfire risk and smoke exposure. Check AirNow.gov for daily AQI data.
The June 2026 NOAA Drought Outlook, published by NCEI, projects that the most serious drought concerns — in the West, Rockies, Plains, Southeast, Mid-Atlantic, and Northeast — are not expected to improve significantly in the near term. Drought is expected to develop further in parts of the Midwest.
Frequently Asked Questions
How much of the U.S. is in drought right now?
As of June 9, 2026, the U.S. Drought Monitor reports that 46.93% of the United States and Puerto Rico, and 56.16% of the lower 48 states, are under active drought conditions (Moderate D1 through Exceptional D4). Severe Drought is expanding in the Northeast, Mid-Atlantic, and Minnesota.
What health risks does drought create?
Drought can reduce and concentrate drinking water, increasing contaminant levels. It amplifies heat illness risk by reducing soil moisture and vegetation. It creates conditions favorable for waterborne disease outbreaks, particularly when drought breaks with heavy rainfall. Extended drought also drives significant mental health impacts, especially in farming communities.
Is my city's tap water safe during a drought?
In most cases, yes — municipal water utilities are required to maintain treatment standards regardless of source water levels. However, very low reservoir levels can strain treatment capacity. Follow your local utility's communications and any boil-water advisories. If you rely on a private well, have it tested.
Which states are in the most severe drought?
As of June 2026, Utah and Washington have declared statewide drought emergencies. Utah is experiencing one of its worst droughts in recorded history, with snowpack at its lowest level since 1930. The Colorado River basin — affecting Arizona, Nevada, California, Colorado, Utah, Wyoming, and New Mexico — faces particularly serious long-term water supply concerns.
What can I do to protect my health during a drought?
Monitor local water quality advisories, test private wells if you have them, stay hydrated and cool during heat events, follow local water restriction orders, and check AirNow.gov for wildfire smoke air quality data if you are in or near fire-prone areas.
