Updated: February 28, 2001

See definitions.

Maryland And Delaware. -- Streamflow increased throughout the entire bi-state area. In Western Maryland and on the upper Potomac River, streamflow increased, moving from the below into the normal range.  In Central Maryland, flows increased slightly, and moved from the normal into the below normal range. Flows on the lower Potomac River increased, and  moved from the below into the normal range. In north east Maryland, flows increased, and remain in the normal range.  On the Eastern Shore, streamflow increased, also remaining in the normal range.

Contents of the Baltimore reservoir system increased, and near month's end were 87 percent of capacity. End of month contents = 66,370 million gallons.

Ground-water levels, near months end, were below average throughout most of the bi-state area:  In western Maryland, ground water levels rose, and remain in the below-average range. In west-central Maryland, ground water levels increased,and remain in the below-average range. In central Maryland, water levels increased, also remaining in the below-average range. On the Eastern Shore, water levels rose, and remain in the above-average range.
