Recent analysis of land use and land cover data from the Chesapeake Bay Program’s Very-High Resolution Land Use/Land Cover and Change Data show 1,927,940 acres (3,012.4 square miles) throughout the watershed are covered by impervious surfaces. This represents 4.75% of the entire land area of the Bay watershed (an area of approximately 40,546,643 acres, or 63,354 square miles). Impervious surfaces are considered to be any area that blocks the filtration of water.

In 2022, an estimated 76,462 acres of underwater grasses were mapped in the Chesapeake Bay and its tidal tributaries, which is 12% higher than in 2021 and 9% higher than the long-term average taken between 1984 and 2022.

Researchers from the Chesapeake Bay Program, the University of Maryland Center for Environmental Science, University of Michigan and U.S. Geological Survey announced today that they are predicting the 2023 dead zone to be significantly smaller than the long-term average taken between 1985 and 2022.

The eighth annual Chesapeake Bay Awareness Week will take place from June 3-11, 2023. While this week has been officially designated in Maryland, Pennsylvania and Virginia, events will take place throughout the entire watershed to raise awareness about this valuable economic and environmental resource—a national treasure that directly connects over 18 million residents.

Reducing the amount of pollution entering the Chesapeake Bay and improving its water quality is proving to be more challenging than anticipated, according to a new report released by the Scientific and Technical Advisory Committee (STAC) for the Chesapeake Bay Program. The STAC, an independent entity that provides scientific and technical advice to the Chesapeake Bay Program, has spent the past four years evaluating reasons as to why progress in meeting the goals of the Chesapeake Bay Total Maximum Daily Load (Bay TMDL) and achieving water quality standards in the Chesapeake Bay has been slower than anticipated. The report also offers suggestions on how progress can be accelerated moving forward.

The Chesapeake Bay Program’s Scientific and Technical Assessment Committee is pleased to release Achieving Water Quality Goals in the Chesapeake Bay: A Comprehensive Evaluation of System Response. This independent report has been four years in the making to evaluate why progress meeting the Chesapeake Bay Total Maximum Daily Load and achieving healthy water quality standards in the Bay has been slower than expected. The report also identifies opportunities for improving the effectiveness of the Bay Program’s water quality management programs and living resource response. Authors of the report will be on hand to present an overview of findings and answer questions.
