Mid-Atlantic groundwater levels starting to decline: Region's streams still at record lows
WASHINGTON, DC, April 7, 2006 -- Despite recent rain, water levels in streams throughout the Mid-Atlantic and surrounding regions remain near record lows for this time of year, according to hydrologists at the U.S. Geological Survey (USGS). Although rains over the past week have improved conditions in parts of the Midwest, West Virginia and Ohio, rivers and streams from northwestern Pennsylvania to southeastern North Carolina are still flowing at levels below normal.
"Stream data collected for 109 years by the USGS on the Potomac River at Point of Rocks tell us that normal flows this week should be about 15,000 cubic feet per second, but the actual streamflows are less than 4,000," said Dan Soeder, hydrologist at the USGS Water Science Center in Baltimore, Md. "Levels this low usually don't occur until July or August. Streams were flowing at essentially normal conditions until about mid-February, but have been dropping steadily since then."
The National Weather Service reported that only 0.05 inch of rain fell in March 2006 at Reagan National Airport in Washington, D.C. compared to a normal value of 3.60 inches for the month. Thurgood Marshall BWI Airport near Baltimore recorded similar low values -- just 0.18 inch of rain in March 2006 compared to 3.93 inches during a normal March.
Spring is usually the wettest time of the year in the eastern United States, with high flows in streams from rainfall and snowmelt, and significant infiltration of water into the soil to recharge groundwater aquifers. The dry spring could have impacts later in the summer on regional water resources and on the Chesapeake Bay.
Groundwater levels so far are generally showing relatively minor drops from the dry weather. Declines in water levels of a few feet were observed in wells in eastern Maryland and Delaware during March, but wells in Frederick, Washington, and Allegany counties showed more significant drops.
Although the declines in regional groundwater levels are generally modest, the fact that levels are declining at all is of concern. Spring is the time of year when ground water normally recharges, and the water levels should actually be rising in March, not falling. Seepage of ground water provides the majority of flow to streams during the absence of runoff, and drawdown of the shallow ground water by streamflow will continue as long as precipitation remains below normal.
Most of the municipal ground water used in the region is supplied from deep, confined aquifers, which remain relatively unaffected. If the dry weather continues into the late spring or summer, however, these water resources could face increasing demands.
According to the Baltimore city government, storage in the Baltimore reservoir system is at 100 percent of capacity. The Washington Suburban Sanitation Commission reports that Triadelphia and Duckett reservoirs on the Patuxent River, which serve Montgomery and Prince George's counties, also have nearly full storage, and the U.S. Army Corps of Engineers is showing a near-normal pool elevation in Jennings Randolph Reservoir on the Potomac River.
Freshwater flow into the Chesapeake Bay set a new record low in 2006 for the month of March, averaging 51,500 cubic feet per second (cfs), equivalent to 313 billion gallons per day. This is 65 percent below average for March, and 10,000 cfs lower than the previous March low-flow record set in 1981.
Consequences of the low river flows include reduced nutrient and sediment loads to the bay, and higher salinities because of less freshwater input. Fewer nutrients and less sediment could result in improved water quality conditions for fish and crabs this summer. On the other hand, higher salinities could make oysters more susceptible to disease, impact fresh-water species of underwater grasses, and favor greater numbers of jellyfish.
In May, the Chesapeake Bay Program (CBP) will be producing an ecological forecast of summer conditions. The USGS interacts with the CBP partners to produce the ecological forecast by providing river flow and nutrient loads to the bay as one of the critical pieces of information for the predictions. More information about USGS studies to help with the protection and restoration of the Chesapeake Bay and its watershed can be found at http://chesapeake.usgs.gov.
Streamflow and groundwater levels are used to assess current water conditions and help to predict the potential for flooding and drought. These USGS data are provided to state and local water resource managers, and are critical for making appropriate decisions on water regulation.
Real-time and historical data on streamflow and groundwater levels in Maryland, Delaware, and Washington, DC, are available on the web at WaterData.

• Water Innovate's N-Tox technology wins Shell Springboard award -- CRANFIELD, United Kingdom, April 6, 2006 -- Shell has awarded Water Innovate nearly $70,000 to help extend the market potential of its N-Tox® nitrous oxide monitoring technology. The product was one of just three Southern Region finalists out of 265 entries selected to go through to the Shell Springboard National Final in London. Springboard judges were looking for commercially viable business plans for innovative products and services which would lead to greenhouse gas reductions. Prof. Tom Stephenson, Water Innovate's technical director, explained that N-Tox detects nitrous oxide, a greenhouse gas with almost three hundred times the global warming potential of carbon dioxide. Having recognized this issue, Water Innovate has invested significant resources in developing N-Tox to enable wastewater plant operators to detect nitrous oxide, thereby helping to reduce greenhouse gas release and mitigate global warming effects. The new technique has the additional advantage that, at the same time, it can be used for evaluating nitrification efficiency in industrial and municipal activated sludge systems...
