River Report – ICPRB Stops Drought Monitoring

From Drought Watch to Flood Watch, it is never a dull moment along the Potomac River, a notoriously flashy river. The Onion reported it best with their hard-hitting news piece, Every Place On Earth Has Wrong Amount Of Water.

After months of below-average rain, the Middle Atlantic River Forecast Center predicts the region will receive 4 inches of rain over the next 3 days. Due to the expected river flows, ICPRB has suspended Drought Monitoring.

Unlike the quick thunderstorms, this sustained rain will help recharge our rivers, groundwater, and soil and will go far to reduce our drought.

Of course, if the rain doesn’t come (or doesn’t come again for a long time), ICPRB will be back tracking the drought and keeping you informed.

If the recent weather has you inspired to pen poetry and your are curious about the different drought terms, our recent Facebook post sets it straight >>>

We want to express our appreciation to all of the people who provide us with the data during our daily Drought Monitoring, including water suppliers and partner agencies: Fairfax Water, Washington Aqueduct, WSSC Water, and Loudoun Water, US Geological Survey and the NWS Middle Atlantic River Forecast Center. It is no small task to compile this information and we sincerely appreciate all their help.

Hot of the presses is the Water Supply Outlook for August, the monthly ICPRB report that explores the possibility of regional water supply releases. It indicates that precipitation and temperature will be above-normal through the end of the summer.

Our relationship with invasive, non-native aquatic species in the Potomac River basin is complicated. Alarms are sounded and eradication efforts mobilized for some species (zebra mussels, blue catfish), while concerns about other non-native species fade as they fill empty ecological niches (Asiatic clams) or become prized fisheries (smallmouth bass). The goal of this effort is to convene a one-day, in-person conference to enhance awareness of the ecological roles that aquatic invasive species have or could assume in the Potomac River basin and the adverse impacts they impart when natural controls are missing.

The day will start out with an invasive species case study of blue catfish and lead into research on other invasive species in the Potomac River.

We have extended the deadline for poster presentations. Please submit an abstract if you are interested in having a poster at the event.

River Report – Drought Watch declared for DC Metro Area

On Monday, the Drought Coordination Committee of the Metropolitan Council of Governments (COG) declared a Drought Watch for the DC Metro area which calls for voluntary water conservation measures by the region’s residents and businesses. This is the second level in COG’s four-stage regional drought response plan.

Read ICPRB’s News Release about the Drought Watch >>>

The most recent U.S. Drought Monitor map shows almost 90% of the watershed is experiencing moderate to extreme drought conditions. The extreme drought conditions are concentrated in the western part of the watershed.

Governor Justice of West Virginia declared a state-wide State of Emergency due to impacts from drought.

At least 92 counties and cities in Virginia are in either Drought Watch or Drought Warning status.

The Maryland Department of the Environment declared a Drought Watch for the western part of the state.

Most smaller jurisdictions across the Potomac watershed are a asking folks to voluntarily minimize their water use to reduce the stress on local streams and groundwater. Some cities are imposing mandatory water restrictions.

A Comprehensive Look at Water Use in the Potomac Basin

When the Potomac Basin Comprehensive Water Resources Plan identified a possible inadequacy in the understanding of water-use on a watershed-wide level, ICPRB staff looked into it. The resulting paper, recently published in the Journal of the American Water Resources Association, investigated if the full spectrum of water uses is known —  and needed — in order for sustainable management of water resources.

News Release: ICPRB Joins Regional Partners in Drought Watch Declaration

Click here for a PDF of News Release: ICPRB Joins Regional Partners in Drought Watch Declaration > > >

Low river flow and very little rain in the forecast has prompted regional organizations to ask residents of the DC Metro area to voluntarily conserve water.

Rockville, MD (July 29, 2024) – The Interstate Commission on the Potomac River Basin (ICPRB) joins their regional partners in asking residents and businesses to voluntarily reduce their water use due to the area’s dry conditions.

On July 26, 2024, the Drought Coordination Committee of the Metropolitan Council of Governments (COG) declared a Drought Watch which calls for voluntary water conservation measures for residents of the DC Metropolitan region. This is the second level in COG’s four-stage regional drought response plan.

“Our region’s ‘water supply bank account’-system of reservoirs is full, and we are able to meet the current water needs of the region. This next step will help ensure that remains the case,” states ICPRB’s executive director, Michael Nardolilli.

ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) continues Drought Monitoring by providing a daily report with weather forecast, river flow data, and regional water demand. This information is shared across social media platforms using #droughtmonitoring. They will continue to do so until conditions improve. If flows in the Potomac River continue to drop, they may reach a level that triggers CO-OP Drought Operations, which includes twice daily reports and may require releases from upstream drinking water reservoirs if forecasted flow in the river is not sufficient to meet expected needs.

According to the U.S. Drought Monitor, the Potomac River watershed is in 70% is in either Severe or Extreme Drought Status.

Nardolilli recommends some options to reduce water use:

  • Prioritize your outdoor watering. Only water newly planted trees, shrubs, and lawns. A slow drip (versus a heavy pour) will allow the water to reach the root system and not run off the soil.
  • Check faucets and toilets for leaks.
  • Take short showers instead of baths.
  • Run the dishwasher and laundry only when full.

Reducing water use will help protect the area’s water supply as well as the aquatic ecosystems of local rivers and streams.

“While nearly 6 million people rely on the Potomac River for drinking water, we can work together as one to reduce our water use and protect this valuable resource,” says Nardolilli.

River Report – New historic minimum flows

There is now a lot of red on the U.S. Drought Monitor map, with 43% of the watershed in Extreme Drought (red) and 28% in Severe Drought (dark orange).

River flows in some areas of the watershed are reaching new record lows. The river flow at the USGS gages at Shenandoah River at Millville, WV, and South Branch Potomac River near Springfield, WV, both hit a century-old recorded historical low this week.

Adjusted flow at Little Falls as of July 17, 2024

Closer to the DC Metro area, the adjusted flow at Little Falls is hovering around the 10th percentile (see the graph).

Some jurisdictions across the western part of the Potomac River watershed are asking residents to conserve water, while some communities are making cutbacks mandatory.

Low river flows, lack of scouring pulses from rain, and record-breaking temperatures are leading to a series of algal blooms throughout the basin. Health officials recommend you (and your dog!) avoid contact with algal mats, especially if the water is discolored, murky, or smelly.

ICPRB continues daily drought monitoring. Check out #droughtmonitoring on social media to see our daily report on river flow, water demands, and weather forecasts.

New Water Supply Outlook Published and Back in Drought Monitoring

On July 5, ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) resumed daily Drought Monitoring. The threshold to begin Drought Monitoring is when the river’s flow at the USGS Gage at Point of Rocks dips below 2,000 cubic feet per second (cfs).

The July Water Supply Outlook suggests we might be headed for a dry summer. Streamflow is currently below normal, and groundwater levels are below normal. 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.

Drought in the Potomac River watershed:
  • 52% in moderate drought conditions
  • 38% in severe drought conditions
The report states drought is likely to persist in the Potomac Basin over the coming months.
Currently, there is sufficient water to meet our demands. If low-flow conditions further develop, we are protected from a water supply shortage owing to carefully designed drought-contingency plans.

River Report – Drought Monitoring suspended, for now

After less than a week of daily Drought Monitoring, we are back to normal operations after suspending the daily reporting on July 1.

However, as of this morning, the flow at the USGS Point of Rocks gage is hovering at the Drought Monitoring threshold of 2,000 cubic feet per second (cfs). The adjusted flow at Little Falls was below the 10th percentile on July 1.

ICPRB CO-OP staff will be monitoring the flows and forecast to determine whether we will be going back into Drought Monitoring. It is not unusual to have Drought Monitoring in fits and starts throughout the dry season.

Follow #droughtmonitoring on social media to get up-to-date Drought Monitoring information from ICPRB.

Drought is still in the news, from lawn care tips to increased fire danger. June was the fourth driest on record for the DC area. The excessive heat could lead to harmful algal blooms which can be dangerous to humans and pets in the water. Shenandoah National Park has closed fishing due to low flows. Some municipalities, like Strasburg, Virginia, are grappling with an equitable approach to drought restrictions while other Virginia counties are asking folks to voluntarily conserve water.

The best way to beat the heat is by getting in the water. Even with the low river flows, there are still plenty of ways to enjoy the plethora of outdoor adventures this region has to offer. Join ICPRB and the Potomac Riverkeepers next Friday for a kayak and snorkel adventure in the Shenandoah, Seneca Rocks Discovery Center is offering snorkel programs through the summer, and there is a new outdoor outfitter to check out.

Bringing our Partners Together

Last week, ICPRB gathered our Federal partners for a day of collaboration and inspiration at the Reservoir Center for Water Solutions. The day focused on identifying areas of common interest and opportunities to collaborate with our Federal partnerships to implement the Potomac River Basin Comprehensive Water Resources Plan.

Projects and partnerships were discussed while attendees learned about ICPRB’s scientific research, regional collaboration, and educational programs. There was inspired conversations, creative thinking, and camaraderie as we worked together towards our parallel goal of protecting our shared natural resources. Future project ideas that were discussed will address better spill response, expand data management, collaborate on educational opportunities, include more diverse communities, and much more.

We’re Growing new Mussels

Thanks to everyone that joined us for last Saturday’s Walk in the Woods: Mussel Power! We had such a blast learning all there is to know about freshwater mussels with our friends at Anacostia Watershed Society (AWS) and our esteemed expert, Jorge Bogantes.

Did you know that some mussel species can live up to 100 years? The average alewife floater or eastern lampmussel that one would encounter in the Anacostia Watershed has a lifespan of 30-40 years. Of course, that’s if a muskrat or blue catfish doesn’t get to them first.

We even got to welcome a fifth species to the Anacostia (eastern elliptio)!

This wraps up our spring/summer Walk in the Woods series of free, fun, and informative hikes. We start the series again this fall with a couple events on the calendar already.

Drought Monitoring suspended, for now

After less than a week of daily reports, ICPRB is suspending Drought Monitoring as flow at the USGS gage at Point of Rocks has exceeded the daily threshold of 2000 cubic feet per second (cfs). It is predicted flows will stay above this threshold for at least the next 5 days.

River Report – ICPRB Initiates Drought Monitoring

It’s dry. While the low humidity might feel pretty good, our river and groundwater levels are suffering. ICPRB has initiated daily Drought Monitoring. A Drought Warning has been declared for much of Northern Virginia. The flow at Little Falls (see the graph) is between the minimum in recorded history and the 10th percentile.

We had a good winter as far as rain was concerned. Things were looking up after a dry 2023. However, we are now 58% below average for the past 30 days. The lack of rain combined with the high temperatures has created a flash drought situation.

ICPRB and our partners across the watershed are monitoring the situation. When flow of the Potomac River at the Point of Rocks USGS gage dips below 2,000 cubic feet per second (cfs), the staff at ICPRB’s Section for Cooperative Water Supply Operations on the Potomac (CO-OP) initiates daily drought monitoring. This means that CO-OP staff prepare a daily report with flow, water demand, and weather forecasts on behalf of the CO-OP water suppliers: Fairfax Water, Washington Aqueduct, and WSSC Water. This is a requirement of the Water Supply Coordination Agreement of 1982, which is a pivotal planning document that helps ensure the DC Metro area is well prepared during a drought.

Follow the conversation across social media platforms using #droughtmonitoring.

There is a little rain in the forecast, but even if we get some rain, grass and other vegetation will still be dry. Firefighters are encouraging everyone to be safe and smart when it comes to their 4th of July celebrations. The safest way to enjoy fireworks is to leave it to the professionals, but if you are going to have your own rocket show, celebrate responsibly:

🌾 Avoid setting off fireworks in areas with dry vegetation

🌊 Have a hose on hand in case of sparks

🧨 Place spent fireworks in a bucket of water

🎆 Happy 4th of July! 🎆

What to celebrate this week: National Catfish Day (June 25)

A national holiday since 1987, this day commemorates the whiskery fish that is found on every continent except Antarctica. Although there are native species of catfish that deserve honoring, the blue catfish does not warrant celebration. It is increasingly becoming a problem as an invasive species in the Potomac and other Chesapeake Bay tributaries.

One way to address invasive species is to put them on the menu. Departments of natural resources are working to make them more appetizing to help fight this invasive species that eats everything from rockfish eggs to crabs.

Put blue catfish on your menu with these creative recipes!

On October 17, ICPRB will be hosting a conference on addressing invasive species—2024 Potomac River Conference: Reeling in the Challenge of Aquatic Invasive Species. Sign up to get notified once registration opens >>>
