USGS Chesapeake Accomplishments for 2021

The U.S. Geological Survey (USGS) works with Federal, State, and academic science partners to conduct monitoring and research in the Chesapeake Bay ecosystem, the Nation’s largest estuary. The USGS interacts through the Chesapeake Bay Program (CBP) to apply science for restoration and conservation decisions.

The CBP consists of the Federal Government, six states, and the District of Columbia, to make progress toward achieving the goals in the Chesapeake Watershed Agreement (2014-25). The agreement goals range from sustaining fisheries, improving water quality, recovering habitats, conserving healthy watersheds and vital lands, engaging citizens, and addressing climate resiliency.  USGS Chesapeake studies also collaborates with and informs work in other critical ecosystems across the country.

USGS revised Chesapeake Science Strategy for 2021-25 around four themes:

  • Theme 1: Develop an integrated understanding of the factors affecting stream health, fish habitat, and aquatic conditions.

  • Theme 2: Assess the risks to coastal habitat and migratory waterbirds.

  • Theme 3: Characterize land use to assess the vulnerability and resiliency of habitats and healthy watersheds. 

  • Theme 4: Integrate science and inform decision making. 

USGS Chesapeake studies are supported by multiple Mission Areas (Ecosystems, Water, Core Science Systems, and Hazards), collectively providing about $15M in 2021. The integrated, multi-disciplinary projects and monitoring are carried out by scientists in multiple USGS Science Centers.

Selected highlights during 2021 include:

Fish Habitat, Populations, and Health
Stream Health
Toxic Contaminants 
Nutrients and Sediment
Coastal Habitats
Characterize Land Use and Change
Integrate Science and Engage Partners
