Water Resources Review – November 2001

Updated: November 30, 2001

See definitions.

Maryland And Delaware. -- Streamflow was below normal throughout the entire bi-state area. In Western Maryland and on the upper Potomac River, streamflow decreased, and remained in the below-normal range. In Central Maryland, flows increased slightly, although moving from the normal into the below normal range. Flows on the lower Potomac River decreased slightly, and remained in the below-normal range. In northeast Maryland, flows showed a slight increase, however, continue to remain in the below-normal range (6 of the last 7 months below normal flows). On the Eastern Shore, streamflow also increased slightly, and moved from the normal into the below normal range.

Contents of the Baltimore reservoir system decreased, and near month's end were 68 percent of capacity. End of month contents = 51,430 million gallons.

Ground-water levels were below normal throughout most of the bi-state area. In western Maryland, ground-water levels rose, although remaining in the below-normal range. In west-central Maryland, ground-water levels decreased, also remaining in the below-normal range. In central Maryland, water levels increased slightly, and remained in the below-normal range. On the Eastern Shore, water levels fell, and remain in the below-normal range.

Normal is defined as the median (50th percentile) of long-term monthly-mean discharge or monthly total runoff. The normal range is defined as discharge or runoff falling between the 75th and 25th percentiles of long-term records.
