Water Science for Maryland, Delaware and the District of Columbia

 


Welcome to our homepage! This site is your source for water-resources information collected and interpreted by the U.S. Geological Survey representing Maryland, Delaware, and the District of Columbia.

The 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. These hydrologic data and other data are used in research and hydrologic studies to describe the quantity, quality, and distribution of the area's water resources. The collection, analysis, and interpretation of these data are done in partnership with other federal, state and local agencies, universities, and research centers.

We also maintain and monitor a network of real-time data-collection sites throughout the region. Read our >>Science Strategy<< to learn more about our goals and operations.

 NAWQA Chesapeake Bay
Maryland's water supply comes from streams and rivers, groundwater, and reservoirs. In the Baltimore region and other metropolitan areas, the primary source of water is surface water (streams or reservoirs). Water regulators, planners, and policy makers need to know how much water can be withdrawn from wells and streams without causing adverse impacts.
The National Water Quality Assessment (NAWQA) is a national program of the U.S. Geological Survey designed to provide consistent and reliable information on the quality of streams, groundwater, and aquatic ecology in the United States. Primary goals of the NAWQA program include determining the status of streams and groundwater, identifying changes over time, and understanding interacting natural and human influences on observed status and trends.
The Chesapeake Bay, the Nation's largest estuary, has been degraded due to the impact of human-population increase, which has doubled since 1950, resulting in degraded water quality, loss of habitat, and declines in populations of biological communities. Since the mid-1980s, the Chesapeake Bay Program (CBP), a multi-agency partnership which includes the Department of Interior (DOI), has worked to restore the Bay ecosystem.
