Current Drought Status

June 2026

The Drought Coordination Committee of the Metropolitan Washington Council of Governments (COG) issued a drought watch on June 3, 2026. The regional Drought Watch applies to nearly six million residents across the District of Columbia, suburban Maryland and Northern Virginia including Prince William County.

COG issued the Drought Watch due to persistent dry conditions, including record-breaking temperatures, historically low Potomac River streamflow and a two‑year rainfall deficit of nearly eight inches. These indicators point to a growing risk of more severe drought, prompting officials to encourage voluntary water conservation across the region.  

In response to the drought watch, we are encouraging our customers throughout our service area to voluntarily practice wise water use:

  • Monitor watering lawns, plants and shrubs; 
  • Sweep sidewalks and driveways (instead of using a hose); 
  • Avoid washing your car, or instead use a commercial car wash that recycles water; 
  • Fix any plumbing leaks – especially toilets and faucets; 
  • Reduce shower length; 
  • Turn off water while brushing your teeth; and 
  • Wash full loads of dishes and clothes.

Overview

Prince William Water is committed to providing safe, reliable drinking water for every household, business and community we serve.

To ensure long‑term water reliability, we continuously monitor regional water supply conditions such as rainfall, river flow, groundwater levels and weather forecasts.

Prince William Water participates in regional drought planning with the Metropolitan Washington Council of Governments (COG). As Prince William County is in the Potomac River Watershed, Prince William Water follows the drought designations of the Interstate Commission on the Potomac River Basin (ICPRB). 

ICPRB issues reports monthly from April through November. This page will be updated periodically. Please refer to the ICPRB website for the latest drought information.

Impact of Droughts

Drought conditions can impact our region’s water supply, local streams and groundwater levels. Higher temperatures can lead to faster evaporation of water. As a result, rivers and reservoirs will have visibly lower levels, groundwater may recharge slower and water demand may increase. Droughts can stress local plants and wildlife, and increase operational challenges for utilities, farms, businesses and the broader community. 

ICPRB reports the drought status for the Potomac River Basin that affects the primary drinking water source in Prince William County; however, other drought classifications may also apply to residents and businesses based on where they are located. 

Prince William Water's Response to Droughts

No matter the weather or drought conditions, we work around the clock to ensure that we provide reliable and safe drinking water for Prince William Water customers. Our teams work daily to track supply levels, adjust system operations as needed and coordinate with regional partners to protect long-term water reliability.

Prince William Water encourages customers to use water wisely year-round, with heightened outreach and conservation messaging during drought conditions. Additionally, under Prince William County Code §30‑84, the Board of County Supervisors and the County Executive are authorized to enact drought‑related water use restrictions. Prince William Water works closely with its regional partners and Prince William County to coordinate efforts when restrictions are anticipated.

Prince William Water supports conservation efforts, provides operational expertise and helps communicate restrictions once they are issued.
