The Week’s River Report: Slight relief came but will it last?

What a difference a week makes.

The Potomac’s flashiness was on full display over the weekend as the flow shot from historical lows to the upper echelons of the graph. But will it remain? Doubtful.

The Potomac watershed is in a donut-hole over the next week—but not the good kind, the dry kind. With very little rain in the forecast, NOAA/NWS predicts flows to plummet, again.

However, the U.S. Drought Monitor map showed some relief over last week thanks to the 2-5 inches of rain in the region.

Severe and Extreme Drought conditions remain but were reduced in size. Currently, 58% of the region is in Moderate Drought, 31.5% in Severe Drought and 8.5% in Extreme Drought.

Letter to the Editor on Data Centers

**In early May an editorial was published in The Washington Post, “The right response to the data center backlash”. The following is a recently published Letter to the Editor penned by ICPRB Executive Director Michael Nardolilli in response.**

I am the executive director of the Interstate Commission on the Potomac River Basin, the agency designated by Congress for the “integration and coordination of the planning for the development and use of the water” in the Potomac River watershed.

The ICPRB is neither for nor against data centers. Nonetheless, we do believe that decision-makers and the public need more data on data centers. D.C. and Arlington are the two most vulnerable cities in the U.S. to a cutoff of their drinking water because they have only one source of water (the Potomac River) and only a one-day backup supply. Should an extreme drought occur in 2050, an ICPRB study indicates, “serious water supply shortages are likely unless additional resources are added to the system.” Though national data suggest data centers account for a small portion of U.S. freshwater use, such averages obscure intense local and regional stress. The ICPRB projects that by 2050, data center water use in the D.C. area will increase to approximately 22 million gallons per day on average and more than 80 million at summer peak use.

Data centers should address the lack of transparency surrounding water use and water quality implications. Nondisclosure agreements hamper agencies, such as ours, from accessing site-specific water demands. Virginia’s recently enacted bill requiring specified water users to report monthly volumes of potable and reclaimed water supplied to data centers and other users is a welcome first step. So is Maryland’s legislation requiring an analysis of the likely environmental, energy and economic impacts of data center development in the state.

In short, the right response to the data center backlash is better transparency and more vigilance regarding water consumption.

Michael Nardolilli, Arlington

This Week’s Potomac News Reservoir – May 14, 2026 >>>

The Week’s River Report: A gloomy Water Supply Outlook, flows hovering around record lows for May

Even though some much-needed rain fell yesterday across the basin, this week’s U.S. Drought Monitor Map still shows the Potomac basin overwhelmingly in the Severe Drought category, at 95.7%.

🟥 A small area in the southern portion of the map (1.3% of the basin) is in Extreme Drought conditions. In the past 30 days, the basin has only received an average of 1.7 inches of rain, 1.9 inches below normal.

👀 This month’s Water Supply Outlook, a monthly report recently published by ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP), estimates a 23 to 34 percent probability that flow will become low enough later this year that a release of water from upstream reservoirs would be needed to boost water supply.

📉 Flows at the USGS gage at Little Falls have been below historic minimums for several days. Today’s flow at Point of Rocks was 2,680 cubic feet per second (cfs), barely above the lowest recorded value on today’s date, 2,600 cfs.

💧 Right now, there is sufficient flow in the Potomac River to meet demands in the Washington Metro Area, though it will help if everyone can do their part to conserve water, especially when it comes to outdoor uses like watering lawns and gardens.

🤝 Should low flows worsen, the metro area is well‐protected from a water supply shortage through cooperative planning.

Protecting Drinking Water at the Source

Earlier this week, members of the Potomac River Basin Drinking Water Source Protection Partnership (DWSPP (http://www.potomacdwspp.org/) ) met for their quarterly meeting. On the agenda: 🗺️ An overview from Nicole Horvath on the Reservoir Center for Water Solutions real-time, public-facing monitoring program with the chance for members to provide feedback on future monitoring locations. (Stay tuned for more information on this soon!) 🥤 A presentation from William Isenberg on the goals and partnership opportunities of the Virginia Department of Environmental Quality’s Marine Debris Reduction Plan.

See more photos on ICPRB’s Facebook page >>>

Coordinated by ICPRB, the Partnership is a voluntary association of water suppliers and government agencies focused on protecting sources of drinking water in the Potomac River basin. By undertaking a collaborative approach, the unique Partnership helps to ensure that people’s most basic need for clean, safe and abundant water is reliably met.

ICPRB Publishes Water Supply Outlook for May

The Interstate Commission on the Potomac River Basin (ICPRB)’s Section for Cooperative Water Supply Operations (CO-OP) has published the Water Supply Outlook for May 2026. The Water Supply Outlook is published on a monthly basis between the drier months from April to October, and provides an update on the possibility of water supply releases from the area’s reservoirs based on long-term precipitation data, flows, and other information for the Potomac basin.

According to the report, there is an above-normal probability of releases from the Washington metropolitan area’s back-up water supply reservoirs for the 2026 summer and fall seasons. Typically, the use of the Jennings Randolph and Little Seneca reservoirs is triggered by low river flows resulting from a combination of low summer precipitation and low groundwater levels. The Potomac basin upstream of Washington, D.C., received 2 inches of precipitation in April, which is 1.4 inches below normal. As of May 1, the 12-month cumulative precipitation is 37.4 inches, or 2.6 inches below normal. Streamflow has reached historical low records for this time of the year. Groundwater levels remain below normal across much of the basin. The U.S Drought monitor indicates extreme drought to abnormally dry conditions are present in the Potomac basin. The seasonal drought outlook indicates drought Is likely to persist over the coming months.

There is a 23 to 34 percent conditional probability that natural Potomac flow will drop below 600 to 700 million gallons per day (MGD) at Little Falls through December 31 of this year. At these flow levels, water supply releases from Jennings Randolph and Little Seneca reservoirs may occur. Releases occur when predicted flow is less than demand plus a required environmental flow-by. Drinking water demand ranges from 400 to 700 MGD during the summer months and the minimum flow-by at Little Falls is 100 MGD. Note that natural flow is defined as observed flow at the Little Falls gage plus total Washington metropolitan Potomac withdrawals, with an adjustment made to remove the effect of North Branch reservoir releases on stream flow.

The conditional probability is estimated by analyzing historical stream flow records and considering recent stream flow values, precipitation totals for the prior 12 months, and current groundwater levels. Years with watershed conditions most similar to current conditions are weighed more heavily when determining conditional probability. In contrast, the historical, or unconditional, probability is based solely on the long-term record without adjustment for current conditions. The 23 to 34 percent conditional probability compares to the 8 to 15 percent historical probability and is considered the more reliable indicator.

At present, there is sufficient flow in the Potomac River to meet Washington metropolitan area’s water demands without augmentation from upstream reservoirs. If low‐flow conditions worsen, the metro area is well‐protected from a water supply shortage through well-established contingency plans.

🌊 New low flow record; 🏆Potomac Critter of the Year; ✨ EPA says cleanup is finished; and more, in this week’s Potomac News Reservoir – May 7, 2026 >>>

The Week’s River Report: Extreme drought on the map and new record low flows

The U.S. Drought Monitor Map released this morning has a small area in the southwest corner in Extreme Drought conditions (red) with 92% in Severe Drought conditions (dark orange).

The dry conditions in Virginia have prompted several local governments to institute burn bans due to increased wildfire risk.

New record low flows continue to be set. Today, the USGS gage at Little Falls is 3,570 cubic feet per second (cfs), while the 96-year historical low for this time is 3,820 cfs. That low was set in 1969, not coincidentally around the same time that ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) was established. This is the section of ICPRB tasked with drought monitoring and operations.

ICPRB was originally established in 1940 to address water pollution issues, but in 1970 — after several years of extreme drought — the compact was amended to empower the organization to work on water resources, with the understanding that a coordinated operation of water resources across jurisdictions will create a more resilient system overall. CO-OP is tasked with drought monitoring and operations.

News From Around the Basin – April 30, 2026

The Week’s River Report: Following the Flow

The recent rain hasn’t boosted river flows much. At 3,240 cubic feet per second (cfs), the flow at Point of Rocks is only slightly higher than the 130-year historical low for this time period of 3,000 cfs.

The adjusted flow at Little Falls has dropped into the lower ranges earlier in the year than seen during previous droughts in 1999 and 2002.

Rain in the basin is 6.4 inches below normal since last fall. That timing is important because this is typically the period when groundwater recharge supports future streamflow.

Flows are even lower now than they were during the same time last year. The spring low flows in 2025 bounced back when the region received heavy rain — up to 11 inches in some areas of the basin — in early May that lead to widespread flooding.

According to the U.S. Drought Monitor Map released this morning, 93% of the watershed is in severe drought conditions, an increase of 11% over last week.

NOAA’s 7-day forecast calls for 0.01-1.0 inch of rain in the watershed, with the majority of the basin receiving the lower end of the forecast.

New historical low flow; data centers and water; lawsuit over the Potomac Interceptor spill; and more in this week’s Potomac News Reservoir – April 23, 2026 >>>

The Week’s River Report: New historical low

It appears we have reached a new historical low flow for this time of year. Current flow at the USGS Point of Rocks gage is 3460 cubic feet per second (cfs) while the lowest flow for today in the 131-year record was 3860 cfs.

Today’s U.S. Drought Monitor Map is bright orange, with 82% of the Potomac River watershed in Severe Drought conditions.

The Virginia Department of Environmental Quality (DEQ), has declared a Drought Warning across  almost the entire state. This advisory level is intended to spread awareness that the “onset of significant drought event is imminent”.

Western and central Maryland are in a Drought Watch status, while the eastern shore is under Drought Warning. Central Maryland drought status is subject to agreements with subject to agreements with the Metropolitan Washington Council of Governments (MWCOG).

🚜 Nine Maryland counties and 24 Virginia localities have received drought disaster declarations from the USDA. Farmers across the basin may be eligible for Farm Service Agency emergency loans due to the drought declarations.

🧯 Officials are warning of an increased wildfire risk due to the ongoing dry conditions.

💧We would like to remind everyone to please use water wisely as conditions across the basin are dry. Some examples:

  • Take shorter showers
  • Only run the laundry or dishwasher with a full load
  • Turn the tap off when you aren’t actively using it

Data Centers: What About Water?

News From Around the Basin – April 16, 2026

River flow at near historical low; Potomac declared endangered; first Water Supply Outlook of 2026; and more, in this week’s Potomac News Reservoir – April 16, 2026 >>>

This Week’s River Report: Water Supply Outlook released

The U.S. Drought Monitor Map released this morning shows the area in severe drought status creeping up (31%) with the remainder of the region in moderate drought.

The river’s flow at Little Falls is close to the lowest historical flow for this time of year.

The first Water Supply Outlook of 2026 was released earlier this week by ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP). The monthly report provides an update on the possibility of low flow conditions in the Potomac basin.

Here are few key excerpts:

  • There is an above-normal probability of releases from the Washington metropolitan area’s back-up water supply reservoirs for the 2026 summer and fall seasons.

  • As of April 1, the 12-month cumulative precipitation is 37.6 inches, or 2.2 inches below normal.

  • Streamflow and groundwater levels remain below normal.

  • Precipitation is expected to be near normal over the next couple of weeks. At the same time, higher-than-normal temperatures are expected to increase evaporative demand.

Drought status across the region

As of March 31, the Central and Western drought regions in Maryland are under a drought watch while the Eastern drought region is under drought warning. In Virginia, five regions are currently under a drought warning, including Shenandoah and Northern Virginia, while several are under a drought watch. In Pennsylvania, portions of the Potomac River basin, primarily Franklin, Fulton, and Bedford Counties are under a drought warning. The metropolitan regional drought stage, under the Metropolitan Washington Council of Governments (MWCOG) Water Supply and Drought Response Awareness Plan, is normal.

We’re number one!

We’re number one! We’re number one! Not on a list anyone wants to find themselves, though.

American Rivers just named the Potomac River as America’s Most Endangered River of 2026. Citing the proliferation of data center development and the recent massive sewage spill, American Rivers brings attention to the issues faced by “the economic lifeline and cultural heart of our nation’s capital”, the Potomac.

“ICPRB appreciates the fact that American Rivers has chosen to highlight the vulnerability of the Potomac River and the need to invest in upgrading both our water supply system and our wastewater pipes,” says Michael Nardolilli, Executive Director of ICPRB. “The Nation’s Capital is vulnerable to both severe droughts and contamination events and ICPRB continues to work to make our region more resilient to these and other threats.”

Farewell to Laurel Glenn, and welcome to Ernest Parker

As Ms. Laurel Glenn steps into a well‑earned retirement, ICPRB extends its sincere gratitude for her outstanding service as Director of Administration. No kidding, Laurel truly earned her April-Fools “Mitigator of Madness” title in everything she did, from organizing ICPRB’s payroll and yearly audits with ease, to making our office space safe and sound (in not one but two buildings), to hiring a half dozen new team members and guiding them through orientation, to organizing every last logistical detail of our quarterly meetings of the Commission.

Reflecting on Laurel’s impact, Michael Nardolilli, Executive Director of ICPRB, shared: “I would like to thank Laurel for doing such a great job for ICPRB as our Director of Administration. Among her many other achievements during her tenure, she oversaw ICPRB’s move to our new headquarters as well as spearheading the revision of ICPRB’s Manual of Operations. Laurel will be missed.”

Laurel’s dedication, professionalism, and tireless work made ICPRB’s systems efficient and smooth. We wish her all the best in retirement. Happy trails, Laurel— we appreciate you!

As we say goodbye to Laurel, we are pleased to welcome Mr. Ernest Parker as ICPRB’s new director of finance and administration. Mr. Nardolilli remarks, “I look forward to working with Ernest Parker in his new position at ICPRB. As a CPA who teaches an upper-level accounting course at Montgomery College, Ernest will bring a new skill set to ICPRB’s leadership team.”

Ernest is a seasoned financial management professional with more than 30 years of experience in public accounting, government contracting, and international auditing. A Certified Public Accountant (CPA), adjunct professor of accounting and management, and holder of a doctorate in strategic leadership, he has led audit, assurance, and financial operations across diverse sectors.

Originally from Liberia, Ernest has lived with his family in the Washington, DC–Maryland area for over 25 years. Outside of work, he enjoys staying active through hiking, running, skiing, and racquetball.

We extend a warm welcome to Ernest and look forward to the expertise and leadership he brings to ICPRB.

Interstate Commission on the Potomac River Basin | Rockville, MD
rbourassa@icprb.org | 301.417.4371 | website

ROCKVILLE, MD (April 15, 2026) – Since 1940, the Interstate Commission on the Potomac River Basin (ICPRB) has played a major part in the improvement of water quality in the Potomac River. It was recently announced that ICPRB will receive $650,000 in federal funding under the Fiscal Year 2026 Energy and Water Appropriations Act recently passed by Congress and signed into law by the President.

ICPRB will use these funds to ensure sustainable water uses and supplies, manage human land use for sustainability, protect and improve water quality, improve drinking water quality, and preserve ecological health — all actions that will benefit the more than the 6 million residents of the Potomac River basin.

On being notified of the award, ICPRB Executive Director Michael Nardolilli, acknowledged the critical role played by Maryland Senators Chris Van Hollen and Angela Alsobrooks in securing these important funds. “All of us who call the 14,000 square miles of the watershed of the Potomac River our home are indebted to Senator Van Hollen and Senator Alsobrooks for supporting ICPRB’s important mission in protecting and enhancing the treasured water resources of the Potomac River,” Nardolilli said.

“For more than 80 years, the ICPRB has played a critical role in the restoration of the Potomac River watershed. With $650,000 in direct federal funding we fought to secure, the Interstate Commission can continue its efforts to improve the river’s health, which are more vital than ever – and protect a key drinking water supply that millions in our region depend on,” said Senator Chris Van Hollen, a member of the Senate Appropriations Committee.

“We must guarantee that every Marylander has access to clean drinking water – and that we are striving to reach our goals for ecological health. This year, Senator Van Hollen and I worked to secure $650,000 in federal funding for the Interstate Commission on the Potomac River Basin, which will ensure improved water quality and environmental health in the Basin, benefitting over 6 million residents,” said Senator Alsobrooks.
