News From Around the Basin – January 2, 2025

The river’s year in review, the warmest year on record, snow in the forecast, and more, in this week’s Potomac News Reservoir – Jan 2, 2025 >>>

River Report: Year in Review

If you are one of those who typically only look at the graphs in our weekly River Reports, we have a lot of eye candy for you this week as we look at the year in review.

As Ian Livingston of the Washington Post notes, the year “will be remembered for persistent and record-breaking warmth, recurrent drought, and several significant weather events…”

(1) The adjusted flow at Little Falls gives us a good idea of where the river’s flow was in regards to the average. The spring storms kept the flow above the 50th percentile. However, once we moved out of the wet spring into the dry summer, the flow dipped below the 10th percentile. A few storms blew in after the summer which kept the flow (mostly) above the 10th percentile.

(2) The river’s flow at Point of Rocks shows the flashiness of the river. This means the river moves quickly from low flows to high flows and back again.

(3) According to the National Weather Service’s Middle Atlantic River Forecast Center (MARFC), the Potomac River above Little Falls received precipitation of 1.4 inches below average during 2024. Although we were close to an average amount of rain, much of the rain was in short, heavy bursts (as seen in the previous graphs). There were extended periods without rain during the year.

(4) There were record-breaking temperatures.

(5) The U.S. Drought Monitor is ending the year with over half of the Potomac watershed in Moderate Drought status (56%), while the remaining areas are either Abnormally Dry or in Severe Drought.

We will have a more in-depth Potomac River Year in Review in our 2024 Annual Report, which will be published soon. Stay tuned!

Remy Says, “Just a Pinch!”

Back in October, ICPRB’s director of communications, Renee Bourassa, in partnership with the Maryland Department of the Environment and the Izaak Walton League of America, led a workshop at the Chesapeake Watershed Forum on communications around the impacts of winter salt on water quality.

As part of the workshop, attendees teamed up to design their own salt box art. What is “salt box art”, you ask? Salt boxes are icons of winter in Baltimore. The yellow boxes filled with winter salt provide residents the opportunity to salt their own sidewalks and roads before the city is able to service them. A recent art movement has seen the boxes getting fun and interesting refurbishments. What better place to communicate smart winter salting practices to protect our waterways?

At the forum, workshop attendees teamed up to create their own salt box panel. One lucky team’s art would be sketched by Baltimore artist and business-owner, Juliet Ames.

We are excited to announce that Ames has installed the art just in time for the region’s first real winter storm of the season. See more photos on her Threads and Instagram account.

News From Around the Basin – Dec 5, 2024

ICPRB has a new address, holiday boat parades, an update on drought conditions, and more, in this week’s Potomac News Reservoir – Dec 5, 2024 >>>

River Report: Remaining steady, but dry

While areas north of us are getting slammed with multiple feet of snow, our region is forecasted to receive roughly 1 inch of precipitation in the coming week.

According to the most recent U.S. Drought Monitor, with the exception of a tiny portion in Pennsylvania that is abnormally dry (yellow), almost the entirety of the Potomac River watershed remains in moderate to severe drought conditions. There is not much of a shift in percentages from last week.

The river flow at Point of Rocks continues to fall following last week’s rainstorms but remains above the ICPRB CO-OP Drought Monitoring threshold of 2,000 cubic feet per second.-

As a reminder, the D.C. Metro area remains in the drought watch declared by MWCOG back in July. Much of the Potomac region of both Virginia and Maryland also remains in a drought watch status. Authorities are asking folks to use water wisely by following simple action items like taking shorter showers, only running the laundry and dishwasher when full, and turning off the faucet when not actively using it.

The Past, Present, and Future of the Potomac River

ICPRB Executive Director Michael Nardolilli recently spoke on a webinar with the Master Gardeners of Northern Virginia and Arlington Regional Master Naturalists about the Potomac River and ICPRB’s work.

He took them on a journey through the past, present, and future of our nation’s river, covering the struggles and triumphs of the river that provides drinking water for more than 5 million people in the Metro DC region. Nardolilli revealed the river’s incredible history and dove into drought, contaminants, policies, emergency response, and more.

News From Around the Basin – November 14, 2024

New records set, burn bans across the region, drought watch still in effect, and more, in this week’s Potomac News Reservoir – Nov. 14, 2024 >>>

River Report: October was one of the warmest and driest on record

Our record-breaking streak of 38 days without rain was broken on Sunday. We’ve been dry ever since. A small chance of rain is in the forecast for the coming days. Experts say that we will need an extended period of soaking rain to ease us out of the dry conditions that have caused authorities to enact burn bans as wildfires are popping up throughout the region.

According to NOAA, October was the second-warmest and second-driest on record. Recent USGS research indicates warmer temperatures may have more severe impacts on drought than previously known due to the heat-induced moisture loss. According to the authors, “droughts will last longer, cover wider areas, and become more severe as the climate warms.”

Due to the persistent dry conditions, staff in ICPRB’s Section for Cooperative Water Supply Operations (CO-OP) released a November Water Supply Outlook earlier this week.

Highlights from the report:

  • CO-OP commenced its fourth “Drought Monitoring” period of the year on November 1.
  • The Potomac basin upstream of Washington, D.C., received 0.8 inches of rain in October, which is 2.2 inches below normal.
  • Streamflow is currently below normal.
  • Groundwater levels are below normal in many observation wells in the basin.

According to the U.S. Drought Monitor Map released today (see below), the amount of the Potomac watershed in Moderate Drought jumped by 22% in the past week.

ICPRB’s Webinar: Integrating Climate and Resilience with Equity

Join ICPRB at noon on December 6 for the next installment of our webinar series. Integrating Climate and Resilience with Equity will highlight data and tools to better understand and characterize climate and flooding threats, focusing on vulnerable and underserved communities. We will also explore funding opportunities to support resilient communities.

This webinar will be helpful to policymakers, government agencies, community Green Teams, HOAs, and anyone interested in creating a more resilient community. Click here to register >>>

This webinar series for land use decision-makers is produced by ICPRB as part of the implementation of the Potomac basin-wide comprehensive plan. Find previous webinars on our YouTube page.

November Water Supply Outlook is Published

Due to the persistent dry conditions, the publication period for the Water Supply Outlook has been extended into November.
The ICPRB Section for Cooperative Water Supply Operations (CO-OP) commenced its fourth “Drought Monitoring” period of the year on November 1. CO-OP initiates drought monitoring when the flow at the U.S. Geological Survey (USGS) stream gage in Point of Rocks, Maryland, falls below 2,000 cubic feet per second.
The Potomac basin upstream of Washington, D.C., received 0.8 inches of rain in October, which is 2.2 inches below normal. Streamflow is currently below normal. Groundwater levels are below normal in many observation wells in the basin.
The U.S. Drought Monitor reports that 19% of the Potomac basin is experiencing severe drought conditions, while 52% is facing moderate drought conditions.
