Precipitation in February helped to replenish ground-water levels and reservoir supplies in the Maryland-Delaware-D.C. region, according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. However, improved water-supply conditions will be sustained only if precipitation remains near normal in the coming months. Ground-water levels at the end of February have increased throughout most of the area and are in the normal range throughout the entire bi-state area. Contents of the Baltimore reservoir system increased from 60,740 million gallons (60.74 billion gallons) in January to 65,750 million gallons near the end of February, which was 87 percent of average and 94 percent of last year at this time. End-of-month contents in February 1999 were about 69,490 million gallons.

Flow into the Chesapeake Bay was 80% of average (68.5 billion gallons per day or bgd) for the month of February and was estimated to be about 55 bgd. February streamflow has increased in bi-state area local streams and has moved from the below normal range to the normal range for this time of year. Streamflow at Potomac River near Washington, D.C. has moved from the deficient into the normal range.
