Maryland-Delaware-D.C. Water Science Center
Home
Welcome to our Water Science Center! Water resources of Maryland, Delaware, and the District of Columbia consist of numerous streams, springs, lakes, and aquifer systems. Streamflow, groundwater levels, and water-quality data are collected at numerous locations, and water-use data are collected throughout the area in cooperation with other federal, state and local agencies, universities, and research centers. Feel free to examine the hydrologic data we collect and the scientific investigations we conduct at the MD-DE-DC Water Science Center.
Chesapeake Bay Activities
The USGS has the critical role to provide scientific information for the improved understanding and management of the Bay ecosystem. The USGS works with Federal, State, and academic science partners to provide research, assessment, and monitoring.

Multi-region assessment of chemical mixture exposures and predicted cumulative effects in USA wadeable urban/agriculture-gradient streams
Chemical-contaminant mixtures are widely reported in large stream reaches in urban/agriculture-developed watersheds, but mixture compositions and aggregate biological effects are less well understood in corresponding smaller headwaters, which comprise most of stream length, riparian connectivity, and spatial biodiversity. During 2014–2017,...

Meeting the challenge: U.S. Geological Survey North Atlantic and Appalachian Region fiscal year 2020 in review
The utilization, preservation, and conservation of the Nation’s resources requires well-informed management decisions. The North Atlantic and Appalachian Region (NAAR) of the U.S. Geological Survey (USGS) supports science-based decision making for Federal, State, and local policymakers to meet the challenges of today and into the future. The...
Mapping stream and floodplain geomorphic characteristics with the Floodplain and Channel Evaluation Tool (FACET) in the Mid-Atlantic Region, United States
Quantifying channel and floodplain geomorphic characteristics is essential for understanding and modeling sediment and nutrient dynamics in fluvial systems. The increased availability of high-resolution elevation data from light detection and ranging (lidar) has helped improve methods for extracting these metrics at a greater accuracy across...
