USGS translates our science from reports and journal articles, and engages stakeholders, to inform restoration and conservation decisions across the Chesapeake watershed. Multimedia information includes geologic maps, and from publications, videos, and Geonarratives that provide stories and maps about selected findings.
Various species of field-collected freshwater fish displaying DELT, including A) an eroded fin, B) melanistic areas, C) parasitic leeches (black arrow) and black spots (trematode, white arrows), D) a cyst (on gill), and E) tumors.

Fish collection streams (n= 1,196) for 57 species within the Chesapeake Bay watershed (black outline). Grey circles indicate the presence of observed DELT, and white circles indicate its absence, in at least one individual fish at each stream. Major land use and land cover were obtained from the Chesapeake Bay Program (2023).

Map showing predicted environmental concentrations (PEC) of PFAS in Potomac River watershed streams, where PFAS is represented as the summed concentration of eight PFAS found in wastewater treatment plant discharges, in nanograms per liter (ng/L).

This map displays the 10-year trend for total nitrate + nitrogen (also known as inorganic nitrogen), as well as the total change in flow-normalized loads per acre for total nitrate + nitrite across the Chesapeake Bay Watershed from 2014 to 2023.

The Chesapeake Bay is one of the Nation's largest ecosystem restoration efforts, so monitoring to assess changes in condition is crucial. The USGS is monitoring the status and trends of key indicators for the health of streams and rivers in the Chesapeake Bay watershed.

Narrated presentation that provides a unique, long-term perspective (1950-2050) of the major drivers of nitrogen change up to the present, and forecasts how they may affect nitrogen into the future for the Chesapeake Bay watershed. Information is based off of U.S. Geological Survey Circular 1486.
