From 1998-2022, CBF's State of the Bay report tracked the health of the Chesapeake Bay and provided insight into the progress—or lack thereof—being made. 2022 State of the Bay Report Overall Score: 32 (D+)

Water quality monitoring data in the freshwater, or 'non-tidal,' streams and rivers of the Chesapeake Bay watershed provide information on pollution levels of nitrogen, phosphorus and sediment, and how they have changed over time.

This story map will look at nitrogen, phosphorus, and sediment pollution levels in the Chesapeake Bay.

May 16, 2023 · Because of the large spread of water sources that lead to the Chesapeake Bay in Virginia, there are a significant amount of pollution points that lead to the Bay. This includes, but is not limited to, water runoff, agricultural runoff, deforestation, sewage …

Jan 1, 2016 · Runoff in the Chesapeake Bay watershed carries pollutants, such as nutrients and sediments, to rivers and streams that drain to the Chesapeake Bay. The health of the Chesapeake Bay is therefore affected by changes in streamflow and the amount of pollution the water flowing to the Bay contains.

In 2022, the amount of nitrogen and phosphorus pollution flowing into the Bay from all major rivers was below the 10-year average, in part due to implementation of the Chesapeake Clean Water Blueprint, the Bay’s long-term restoration plan.

Oct 17, 2023 · Our experts also look at the total amount of nitrogen, phosphorus and sediment pollution entering the Chesapeake each year, based on data coming from monitoring stations located on the nine largest tributaries of the Bay.

River and Watershed Input of Pollution Loads. Years denote the water year measured between October 1 and September 30. See how these data are used in the Water Quality Standards Attainment and Monitoring Outcome and the Factors Influencing the Submerged Aquatic Vegetation (SAV) Outcome .

May 3, 2024 · The Chesapeake Bay Program (CBP) announced new results yesterday, derived from its Watershed Model, that estimate jurisdictions in the Chesapeake Bay watershed have made progress towards meeting their 2025 pollution reduction goals.

Jul 9, 2024 · HARRISBURG, Pa. (AP) — The overall health of the Chesapeake Bay, the nation’s largest estuary, received its highest grade since 2002 in an annual report released by scientists Tuesday: a C-plus.
