Outreach

USGS is the Nation's largest natural-science agency and has the principal responsibility within the Federal government for mapping the Nation, assessing its geologic resources and hazards, understanding its natural biological resources, and providing hydrologic information for appraising the Nation's water resources. The Maryland-Delaware-D.C. District Office is mostly involved with conducting water-resources investigations. However, the District Chief (Baltimore) represents all of USGS in Maryland and D.C., and the Subdistrict Chief (Dover) represents USGS in Delaware.

The water resources of Maryland, Delaware, and the District of Columbia consist of numerous streams, springs, lakes, and aquifer systems. Streamflow, ground-water levels, and water-quality data are collected at numerous locations, and water-use data are collected throughout the area. These hydrologic data and other data are used in research and hydrologic studies to describe the quantity, quality, and location of the area's water resources. The collection, analysis, and interpretation of these data is done in cooperation with other federal, state and local agencies, universities, and research centers.

The U.S. Geological Survey provides the Nation with reliable, impartial information to describe and understand the Earth. This information is used to minimize loss of life and property from natural disasters, manage water, biological, energy, and mineral resources, enhance and protect the quality of life, and contribute to wise economic and physical development.

Press Releases and Reports

Current Water Conditions Summary
Updated during the first week of each month, our press releases feature the latest information on ground-water and surface-water in the MD-DE-DC Water Science Center.

Reports on USGS programs in Maryland, Delaware, and the District of Columbia: This page contains a Bibliographical Listing of online publications from the Maryland-Delaware-D.C. district of the US Geological Survey, Water Resources Division.
Estimated Streamflow Entering the Chesapeake Bay Total | Cross Sections: A monthly summary of cumulative streamflow into Chesapeake Bay designed to aid those concerned with studying and managing the Bay's resources. Cumulative streamflow is estimated using data collected near the end of each month from index stations on the Susquehanna, Potomac, and James Rivers.
Potomac River Streamflow: Total streamflow of the non-tidal portion of the Potomac River and the total of diversions for water supply in the Washington area.
Ground-Water Levels in Maryland and Delaware: Current ground-water information maps are listed by county, categorized by water table well or confined aquifer well, with 5 year information.
NWC - Water Resources Review: Updated monthly - featuring information on surface-water and ground-water in the Maryland-Delaware-DC district
