Rainfall in excess of 10 inches occurred during the first 5 days of November 1985, resulting in devastating flooding in the Mid-Atlantic states of West Virginia, Pennsylvania, Maryland, and Virginia. Throughout the area, many streams exceeded previously known flood heights and discharges and, in many cases, the recurrence interval of peak discharges exceeded 100 years.
The peak stage and discharge for the maximum previously known flood and the November 1985 flood are compared. Flood hydrographs for selected locations also are presented.
