The streams and rivers that flow into the Bay are also called tributaries.
The Chesapeake Bay watershed's streams and rivers are home to a diverse population of fish, invertebrates, amphibians and other types of wildlife.
The health of the nation’s most endangered river has improved for the third year in a row.
Sediment pollution overshadows progress in treating wastewater and curbing nutrients.
Volunteer-collected water quality data is a critical part of Chesapeake Bay restoration.
