March rains helped water levels increase across Maryland and Delaware, according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. Additionally, water storage in the Baltimore reservoir system increased by 5 percent to 92 percent of capacity at the end of March.

Streamflow entering the Chesapeake Bay during March also increased to 67.0 bgd (billion gallons per day), but this level is still 21 percent below the long-term average and below-average conditions have persisted since September 2000 (see graphs at http://md.water.usgs.gov/monthly/bay.html). Streamflow at the Potomac River near Washington, D.C., increased by 56 percent over February, but was 26 percent below the long-term average for March. Streamflow at the Choptank River near Greensboro, Maryland, on the Eastern Shore, was 50 percent above normal.

Ground-water levels for Maryland and Delaware continued to increase, putting most water levels in the normal range. Twenty new sites have been added to the monthly updates of ground-water conditions for key observation wells in Maryland and Delaware available at: http://md.water.usgs.gov/groundwater/. The graphs show monthly water levels and long-term records for 39 water-table wells and 13 artesian wells.

The USGS serves the nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.
