Streamflow and Groundwater levels were in the normal range across Maryland and Delaware in August according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. Streamflow at Seneca Creek at Dawsonville, Maryland, was 108 percent above normal and the Potomac River near Washington, D.C., was 42 percent above normal. Storage in the Baltimore Reservoir system also improved and is up to 87 percent of capacity.

Streamflow in Deer Creek near Rocks in Harford County increased in August but continues to be below normal. Streamflow entering the Chesapeake Bay averaged 15.4 bgd (billion gallons per day), which is 22 percent below the long-term average for August (see graphs at The Potomac River contributed a greater percentage of the streamflow (33 percent) entering the Chesapeake Bay in August than the Susquehanna River (23 percent), which reflects the dry conditions in Pennsylvania.

Groundwater levels in water-table wells at the end of August generally decreased, but remain in the normal range for Maryland and Delaware (see graphs at

As the Nation's largest water, earth and biological science, and civilian mapping agency, the USGS works in cooperation with more than 2,000 organizations across the country to provide reliable, impartial scientific information to resource managers, planners, and other customers. This information is gathered in every state by USGS scientists to minimize the loss of life and property from natural disasters, contribute to the sound conservation and the economic and physical development of the nation's natural resources, and enhance the quality of life by monitoring water, biological, energy, and mineral resources.
