Flow of the Potomac River near Washington, D.C., was more than twice the average flow for November, according to the U.S. Geological Survey.

In its second month of above-average flow, the Potomac flow in November was about 7.3 billion gallons per day (bgd), well above the average flow of 3.3 bgd. The highest flow, 18 bgd, occurred on Nov. 16 and the lowest flow, 2.3 bgd, was on Nov. 10.

ON THURS., DEC. 7, 1995, AT 2 P.M., FLOW OF THE POTOMAC RIVER NEAR THE DISTRICT WAS ABOUT 5.9 BGD, FIVE PERCENT BELOW THE DECEMBER AVERAGE FLOW OF 6.2 BGD.

Combined freshwater inflow to the Chesapeake Bay from the Susquehanna River, the Potomac River and the James River was well above normal for the second consecutive month, at about 51.7 bgd, 38 percent higher than the November average inflow of 37.5 bgd.

Ground-water levels around Washington, D.C., rose in November but are still slightly below normal for the 15th consecutive month. At a USGS observation well in Montgomery County, Md., the water level was about 13.6 feet below the land surface, about three-tenths of a foot below the November average level of 13.3 feet.

Contents of the Baltimore reservoir system increased in November to about 69,330 million gallons, 9 percent less than November of last year.

Diversions of Potomac River water for municipal use averaged about 369 million gallons, about 2 percent more than November of last year.
