The Week’s River Report: Holding Steady

It is a mixed bag in today’s River Report.

While the drought status across the region on today’s U.S. Drought Monitor map (see below) holds steady from last week, the flow at the USGS Point of Rocks gage hovers around 2,020 cubic feet per second (cfs). While this is not unusual for this time of year — the median is 2220 cfs — at 2,000 cfs, ICPRB begins Drought Monitoring activities, which means a daily email to water suppliers and other stakeholders with information on flow, water use, and weather forecasts. It’s essentially an extra set of eyes on the data when the flow gets low.

Due to last year’s dry winter, we are still in a rain deficit of 7.6 inches for the past calendar year. However, year to date for 2026 has seen closer to average. (NOAA)

While some rain is expected in the region, it appears NOAA’s 7-day forecast doesn’t have more than an inch across the watershed.

Welcoming new ICPRB Alternate Commissioner for DC

ICPRB Staff and Commissioners would like to welcome Jayne Brown as the newest Alternate Commissioner (DC) to join the Commission. Brown is the associate director of inspection and enforcement at the DC Department of Energy and Environment (DOEE). Her Division regulates industrial, municipal, and construction stormwater and wastewater compliance. Among other board positions, she has previously served as Chair of the Potomac Basin Drinking Water Source Protection Partnership.

“I would like to welcome Alternate Commissioner Jayne Brown to ICPRB in her new capacity. Jayne is no stranger to ICPRB and we look forward to working with her in this new role,” says ICPRB Executive Director Michael Nardolilli.

The ICPRB Commission is composed of three Commissioners and three Alternate Commissioners from the District of Columbia, Maryland, Pennsylvania, Virginia, West Virginia and the Federal Government.

The Week’s River Report: Improvements Continue

Drought conditions continue to improve across the watershed, but as one news article says, it’s still pretty droughty out there.

Today’s U.S. Drought Monitor map remains similar to last week, with a swath of Moderate Drought conditions across the center of the watershed and much of the remaining area Abnormally Dry.

Flow at the USGS Point of Rocks gage is Above Normal (in the 75-90th percentile).

Average rain still remains in a deficit though, at 8 inches below average for the past year.

The Week’s River Report: Improvements Across the Watershed

Good news in this week’s river report. Here it is by the numbers:

🗺️ 0% – Severe Drought in the basin: Today’s U.S. Drought Monitor map shows no Severe Drought conditions in the watershed, a nice improvement over last week. A broad swath of moderate drought runs through the center of the watershed, while most of the remaining area remains abnormally dry.

🌊3030 cubic feet per second (cfs): Flow at the USGS Point of Rocks gage is slightly above median.

☔ -8.5 inches: The region’s rain deficit for the past year, which improved from last week.

🔮 Up to 2 inches: The amount of rain forecasted over the next week, with the higher amounts expected to hit the south-east section of the basin.

Small Systems Roundtable in Moorefield, WV, Brings Potomac Partners Together

ICPRB and the Potomac River Basin Drinking Water Source Protection Partnership (DWSPP) recently brought together drinking water professionals and partners for a Small Water Supply Systems Roundtable focused on the unique needs and experiences of smaller water systems in the Potomac basin.

The gathering created an opportunity for participants to exchange ideas, learn about available resources, and connect with other water professionals working throughout the region.

The event reflected DWSPP’s broader mission of bringing utilities and government partners together to strengthen source water protection throughout the basin.

The day included discussions on source water protection, harmful algal blooms, agricultural best management practices, funding opportunities, spill response and modeling, and watershed protection, along with a tour of the Moorefield water treatment facility. Just as importantly, participants had time to learn from one another and identify successes, challenges, and opportunities that many small systems face. The strong participation and lively discussion made the roundtable a success and demonstrated the value of making sure small systems have a seat at the table in basin-wide source water protection efforts.

The Week’s River Report: August Water Supply Outlook

The August Water Supply Outlook was published yesterday. This monthly report provides an update on the possibility of water supply releases from the area’s reservoirs and gives an overall look at drought in the watershed.

Yesterday’s report shows improvement over earlier this summer. While the July report calculated the chance of needing to release water from upstream reservoirs was up to 48%, the August has up to a 16% chance, which is a more positive outlook for the rest of the year. However, some drought conditions remain.

Here is the full summary:

There is a near-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 3.9 inches of precipitation in July, 0.1 inches above average; as of August 1, the 12-month cumulative total was 29.2 inches, 10.9 inches below average.

Groundwater conditions are generally near normal basin-wide, though above- and below-normal readings occur at individual wells.

Recent rainfall has increased Potomac River streamflow, prompting ICPRB to suspend daily drought monitoring on August 9 after initiating it on August 3 in response to declining flows.

The Climate Prediction Center’s seasonal outlook indicates drought conditions across much of the Mid-Atlantic should improve or be removed by the end of October. A Drought Watch for the metropolitan Washington region remains in effect. Reservoirs remain near full.

At present, Potomac River flow is sufficient to meet metropolitan area water demands without upstream reservoir augmentation. The region remains well protected by established contingency plans should conditions worsen.

Read the full report >>>

Drought conditions remain across portions of the basin with only a slight improvement over last week. As of August 11, about 12 percent was in severe drought (D2), 44 percent in moderate drought (D1), and 37 percent abnormally dry (D0), with no area in extreme drought (D3).

The Week’s River Report

Earlier this week ICPRB initiated daily Drought Monitoring due to low flows in the Potomac River.

Staff in ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) begins daily Drought Monitoring when flow at the USGS stream gage at Point of Rocks, Maryland, falls below 2,000 cubic feet per second (cfs).

During Drought Monitoring, CO-OP staff send out daily email reports to stakeholders, including water suppliers and government agencies, summarizing the river’s flow, weather predictions, and how much water the region is using on a daily basis.

Summary of today’s report:

🌊 Rainfall over the past few days has not raised Potomac River flows significantly. Flow at USGS Point of Rocks gage is 1780 cubic feet per second.

🔮 0.1 to 1.0 inches of rain is predicted over the next 3 days. (MARFC)

A summary of the daily report will also be posted on ICPRB’s socials using #DroughtMonitoring. Find a link to the full report on ICPRB’s Drought Monitoring and Operations website.

Established in the 1970s, CO-OP helps manage the Washington metropolitan area water supply system by recommending and coordinating releases from upstream reservoirs when forecasted flow in the river is not sufficient to meet expected needs.

At present, there is sufficient flow in the Potomac River to meet Washington metropolitan area’s water demands without releases from upstream reservoirs. If low‐flow conditions worsen, the metro area is well‐protected from a water supply shortage through well-established contingency plans, which includes CO-OPs drought monitoring and operations protocols.

🗺️ Today’s U.S. Drought Monitor Map shows a slight improvement in drought conditions over last week, with the most marked improvement seen in the Washington metro region and south along the I-95 corridor, which upgraded from moderate drought to abnormally dry conditions.

Watershed Management Conference Next Week

ICPRB Initiates Drought Monitoring – August 3, 2026

Today, ICPRB has initiated daily Drought Monitoring due to low flows in the Potomac River.

Staff in ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) begins daily Drought Monitoring when flow at the USGS stream gage at Point of Rocks, Maryland, falls below 2,000 cubic feet per second (cfs).

Currently, the flow is 1,740 cfs.

During Drought Monitoring, CO-OP staff send out daily email reports to stakeholders, including water suppliers and government agencies, summarizing the river’s flow, weather predictions, and how much water the region is using on a daily basis.

A summary of the daily report will also be posted on ICPRB’s socials using #DroughtMonitoring. Find a link to the full report on ICPRB’s Drought Monitoring and Operations website.

Established in the 1970s, CO-OP helps manage the Washington metropolitan area water supply system by coordinating withdrawals from the Potomac River and off-river reservoirs and recommending releases from upstream reservoirs when forecasted flow in the river is not sufficient to meet expected needs.

At present, there is sufficient flow in the Potomac River to meet Washington metropolitan area’s water demands without releases from upstream reservoirs. If low‐flow conditions worsen, the metro area is well‐protected from a water supply shortage through well-established contingency plans, which includes CO-OPs drought monitoring and operations protocols.

The Week’s River Report: July’s Water Supply Outlook

July’s Water Supply Outlook was published last week. This monthly report 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. The rundown…

👀 There is an above-normal probability of releases from the area’s back-up water supply reservoirs this  summer and fall.

☔ The Potomac basin upstream of Washington, D.C., received 2.7 inches of rain in June, which is 1.1 inches below normal. As of July 1, the 12-month cumulative precipitation total was 30.8 inches, which is 9.3 inches below normal.

🗺️ The U.S. Drought monitor indicates extreme drought to abnormally dry conditions are present in the Potomac basin. The seasonal drought outlook indicates that drought is likely to persist over the coming months.

🌊 Although conditions improved temporarily during the month, stream flows were much below normal by the end of June and groundwater levels remain below normal across much of the basin.

📣 A Drought Watch for the metropolitan Washington region remains in effect. Authorities are asking for voluntary water conservation among residents and businesses in the region.

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.
