Chesapeake Bay Activities
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.
Science-Based Approach for Targeting Resources

The Chesapeake Bay Program (CBP) needs to accelerate progress on multiple outcomes to meet deadlines in the Chesapeake Watershed Agreement. The CBP partnership spends about $1.2B annually on activities toward achieving the Watershed Agreement, with a focus on water-quality improvement.
