The average streamflow into the Chesapeake Bay was 42.2 bgd (billion gallons per day) in 2000, which was 16 percent below the long-term average, according to hydrologists at the U.S. Geological Survey.
Although the yearly rainfall was slightly above normal, the fall was drier than normal, according to USGS, resulting in the lower yearly average streamflow into the Chesapeake Bay.
The low flows also continued into 2001, according the USGS. January figures showed that streamflows entering the Bay averaged 23.9 bgd, which was 59 percent below normal.
