Current Drought Status

May 2026

The Interstate Commission on the Potomac River Basin (ICPRB) reports that our region is experiencing significant drought conditions. Here’s what that means in everyday terms:

  • About 80% of the Potomac River Basin is in a severe drought. This means the area is much drier than normal and water levels are not recovering quickly.
  • The Potomac River is running at some of the lowest levels ever recorded for this time of year. Lower river flow means less water available for drinking water supplies and the environment.
  • Groundwater and streams are also below normal. This affects wells, small streams and the overall health of the watershed.
  • There is a higher chance that backup reservoirs may need to be used later this year. These reservoirs help support the region’s drinking water supply during extended dry periods.

There are currently no drought restrictions in place for Prince William County. Prince William Water is actively monitoring local and regional water indicators and will communicate promptly if conditions change.

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 shortly after the monthly reports. Please refer to the ICPRB website for the latest drought information. 

Impact of Droughts

Drought conditions can impact on 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.

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.

During some drought conditions, Prince William Water may suggest customers use water wisely. 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 supports conservation efforts, provides operational expertise and helps communicate restrictions once they are issued.
