Date: Wed, 03 Apr 2024 11:21:33 EDT

Summary: Repeated rounds of precipitation resulted in minor to moderate flooding in Maryland, the District of Columbia, and Delaware

In the past 2 days, Maryland, Delaware, and the District of Columbia have received a widespread 3-4 inches of rain, which has caused minor flooding, as defined by the National Weather Service, with an
additional one inch of precip expected today (Wednesday) and overnight. Western Maryland (Garrett, Allegheny, and western Washington County) have been the hardest hit so far; however, the precipitation is heading east and
is starting to affect Central Maryland, including the Baltimore and D.C. Metro Areas and Delaware. The MD-DE-DC Water Science Center has a total of 23 staff responding to this event to measure streamflow and collect water-quality samples.
We are actively monitoring the larger drainages, which will be measured and sampled as needed. Field work is likely to continue through the end of the week and the
first part of the weekend, particularly at the larger rivers such as the Potomac and Susquehanna Rivers.

Field Response by office:
Baltimore, MD: 8 staff measuring streamflow, 6 staff collecting water-quality storm samples.
Dover, DE: 4 staff measuring streamflow.
