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 Chesapeake Bay Highlights for FY2020

USGS Chesapeake Bay Highlights for FY2020

USGS Chesapeake studies are supported by multiple Mission Areas, collectively providing $14.85 million, which included a $2 million increase in 2020. Monitoring and projects are carried out by multiple USGS Science Centers.

New Review of Sediment Science Informs Choices of Management Actions

New Review of Sediment Science Informs Choices of Management Actions

The USGS conducted a synthesis on the state-of-the-art science of sediment dynamics for the Chesapeake Bay watershed to inform restoration efforts. The synthesis reviewed and summarized multiple aspects of sediment.

Development of a suite of functional immune assays and initial assessment of their utility in wild smallmouth bass health assessments

Methods were developed for measuring immune function in Micropterus dolomieu (smallmouth bass). The ultimate objective is to monitor and evaluate changes over time in immune status and disease resistance in conjunction with other characteristics of fish health and environmental stressors. To test these methods for utility in ecotoxicological...

Spatial and temporal patterns in streamflow, water chemistry, and aquatic macroinvertebrates of selected streams in Fairfax County, Virginia, 2007–18

Urbanization substantially alters the landscape in ways that can impact stream hydrology, water chemistry, and the health of aquatic communities. Stormwater best management practices (BMPs) are the primary tools used to mitigate the effects of urban stressors such as increased runoff, decreased baseflow, and increased nutrient and sediment...

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...
