Maryland

Maryland's water supply comes from streams, rivers, groundwater and reservoirs. Many of these systems flow to the Chesapeake Bay, the Nation's largest estuary. This complex ecosystem has been degraded due to the impact of human-population increase. The MD-DC-DE Water Science Center studies the impacts this has on water quality, habitats and biological communities.

January streamflow in the Potomac River at Washington, DC, and total flow into the Chesapeake Bay were the second-highest on record, exceeded only by flows in January, 1996, according to the U. S.Geological Survey (USGS). The generally wetter-than normal conditions increase the likelihood of flooding from storms that may follow.

About half the high nitrate concentrations in nontidal streams and rivers that contribute to the decline of fish populations in Chesapeake Bay come from underground sources, according to research findings presented by the U.S. Geological Survey (USGS) today (Dec 9. 1997).

Analysis of Chesapeake Bay sediment cores collected by the U.S. Geological Survey and the University of Maryland Center for Environmental and Estuarine Studies (CEES) indicates that some of the sediment samples dating back hundreds or thousands of years contain Pfiesteria-like organisms and other microbes.

Scientists from the U.S. Geological Survey (USGS) and other federal and state agencies involved in Chesapeake Baystudies are working together to understand the delivery of nutrients from the land into the Bay and the relationship of nutrients to Pfiesteria-like organisms and ultimately fish health.

The U.S. Geological Survey (USGS) is working with scientists from George Mason University and the Maryland Department of Natural Resources to collect a water sample from the Pocomoke River and analyze the sample for a variety of commonly used pesticides.

"We are extremely concerned about this issue, especially in light of the fish kill which began Wednesday (Aug.6) near the mouth of the Pocomoke River," said USGS Chief Biologist Dennis Fenn.

Total river flow into the Chesapeake Bay was about 16.2 billion gallons per day (bgd) in July, 31 percent below the normal inflow for July (23.4 bgd), according to the U.S. Geological Survey (USGS). The long-term average is based on 47 years of information.

Potomac River flow near Washington, D.C., was well above normal in June at 7.3 billion gallons per day (bgd), one and one-half times the normal flow for this time of year, according to the U.S. Geological Survey.

Total freshwater inflow into the Chesapeake Bay during 1996 was the highest ever recorded, according to the U.S. Geological Survey.
