Chesapeake Bay Activities
Home
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. See our Science page to learn about our themes and topics being addressed.
USGS develops tool to further examine nutrient and sediment trends
USGS has developed the nontidal network mapper to share the short-term (2009-2018) water-year nutrient and suspended-sediment load and trend results for the Chesapeake Bay Program’s non-tidal network.

Estimating streamflow and base flow within the nontidal Chesapeake Bay riverine system
Daily mean streamflow was estimated for all the nontidal parts of the Chesapeake Bay riverine system with the Unit Flows in Networks of Channels computer application using measured streamflow at the most downstream gage of selected rivers. The streamflows estimated by the Unit Flows in Networks of Channels computer application were aggregated at...

Aquatic invasive species in the Chesapeake Bay drainage—Research-based needs and priorities of U.S. Geological Survey partners and collaborators
Executive SummaryThe U.S. Geological Survey (USGS) is revising the Chesapeake Bay-based science plan to align it with recent U.S. Department of Interior and USGS science priorities that include, as stated in the plan, providing “an integrated understanding of the factors affecting fish habitat, fish health, and landscape conditions” in Chesapeake...

Sediment dynamics and implications for management: State of the science from long‐term research in the Chesapeake Bay watershed, USA
This review aims to synthesize the current knowledge of sediment dynamics using insights from long‐term research conducted in the watershed draining to the Chesapeake Bay, the largest estuary in the U.S., to inform management actions to restore the estuary and its watershed. The sediment dynamics of the Chesapeake are typical of many impaired...
