Multimedia
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.

Chesapeake Bay Status and Trends (AD)
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.
