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.
Road salt elevates salinity above background levels in freshwater streams and rivers
The findings of this study show that salinity is elevated above background levels throughout most freshwater streams within the Chesapeake Bay watershed. This information can help prioritize salt management strategies for local streams and rivers.
Susquehanna River Story — What does the science say about water quality?
The wide and majestic Susquehanna River is one of the oldest rivers in the world and provides water for over 4 million people. Despite its beauty, the Susquehanna River and the Chesapeake Bay downstream has been facing the detrimental effects of excess nutrients (nitrogen and phosphorus).
