Update as of 3 pm:

Flow of the Potomac River near Washington, D.C., averaged 4.5 bgd, nearly two and one-half times the average October flow of 1.9 bgd, according to hydrologists at the U.S. Geological Survey.

ON FRI., NOV. 3, 1995, AT 3 P.M., FLOW OF THE POTOMAC RIVER NEAR THE DISTRICT WAS ABOUT 2.5 BGD, 25 PERCENT BELOW THE NOVEMBER AVERAGE FLOW OF 3.3 BGD.

During October, the flow varied from a low of 1.2 billion gallons per day (bgd) on October 4 to a high of 27 bgd on October 23, in response to record October rainfall.

Not surprisingly, total freshwater inflow to the Chesapeake Bay from the Susquehanna, Potomac and James rivers was well above normal at 41 bgd, 50 percent higher than the October average inflow of 27.3 bgd.

Ground-water levels in the region remain below normal for the 14th consecutive month despite heavy October rains. At a USGS observation well in Montgomery County, Md., the water level was about 14.9 feet below the land surface, 1.4 feet below the long-term average for October of 13.5 feet.

Contents of the Baltimore reservoir system decreased in October to about 64.6 million gallons, 16 percent less than October of last year.

Diversions of Potomac River water for municipal use averaged about 396 mgd, about four percent more than October of last year.
