Chesapeake Bay Activities
The Chesapeake Bay is our Nation’s largest estuary and provides over $100 billion in annual economic value. The USGS works with Federal, State, local, and academic partners to provide research and monitoring and to communicate results to inform management for the Chesapeake and other important landscapes across the Nation.
USGS Collaborates on Maryland Healthy Watersheds Assessment
USGS Collaborates on Maryland Healthy Watersheds Assessment
The assessment is intended to inform watershed management decision-making to sustain the health of State-identified healthy watersheds, which have been defined in Maryland as the watersheds associated with its designated high-quality, Tier II waters.
Groundwater Affects Fish Population Stability and Resiliency to Climate Change
Groundwater Affects Fish Population Stability and Resiliency to Climate Change
Researchers surveyed stream fish communities where they were sampled 29-30 years previously and evaluated biological changes based on groundwater processes that promote stable environmental conditions.

Quantifying connectivity and its effects on sediment budgeting for an agricultural basin, Chesapeake Bay Watershed, United States
Excessive sediment runoff as a result of anthropogenic activities is a major concern for watershed ecologic health. This study sought to determine the sources, storage, and delivery of sediment using a sediment budget approach for the predominantly pasture and forested Smith Creek watershed, Virginia United States, a tributary to the Chesapeake Bay. Utilizing a novel combination of the Universal S
A case study: Temporal trends of environmental stressors and reproductive health of smallmouth bass (Micropterus dolomieu) from a site in the Potomac River Watershed, Maryland, USA
Decades of poor reproductive success and young-of-the-year survival, combined with adult mortality events, have led to a decline in the smallmouth bass (SMB; Micropterus dolomieu) population in sections of the Potomac River. Previous studies have identified numerous biologic and environmental stressors associated with negative effects on SMB health. To better understand the impact of these stresso

Improving Understanding and Coordination of Science Activities for Per- and Polyfluoroalkyl Substances (PFAS) in the Chesapeake Bay Watershed
Issue: Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in a variety of industries in the United States since the 1940s. PFAS are ubiquitous and persistent in the environment and have the potential to have adverse human and ecological health effects. The Chesapeake Bay Program (CBP) partnerships has concerns about how PFAS will affect the Chesapeake Bay ecosystem. The CBP...
Chesapeake Bay Land Use and Land Cover data is now published in additional formats
The Chesapeake Bay Land Use and Land Cover (LULC) database was developed by the University of Vermont’s Spatial Analysis Laboratory in cooperation with Chesapeake Conservancy (CC) and U.S. Geological Survey (USGS). The high-resolution land data were developed as part of a 6-year Cooperative Agreement between Chesapeake Conservancy and the U.S. Environmental Protection Agency (EPA), and a separate...
Study reveals importance of groundwater for stability of freshwater fish populations and resilience to climate change
Issue: Climate change is warming streams and rivers of the Chesapeake Bay watershed, and this is a critical concern for fisheries management and conservation. To address this issue, the Chesapeake Bay Program (CBP) recently identified four actions: • address the threats of climate change in all aspects of the partnership’s work; • prioritize communities, working lands, and most vulnerable habitats...
